[Zope] Re: ZPT and attributes
Hi Antonio, Hi all: How I can create attribute names dynamically? tal:attributes=attributename expression Sorry, I haven't explain the problem correctly :) The problem is the number of refX depends on the list of urls, i.e. if I have ['http://foo', 'http://boo', 'http://google.com'] then I create: books ref1='http://foo' ref2='http://boo' ref3='http://google.com' but with ['http://foo'] I create: books ref1='http://foo' How I create refX? Greetings. For example, I want something like this: books tal:attributes=ref1 string:http://boo;; ref2 request/URL3 / And so on. I think you are using zpt for the wrong thing. For me it seems that what you should use would be a xml product like ParsedXML. I haven't used it, but I have taken a look at the source code of Silva and saw that it may be possible to create dynamic attributes with a setAttribute or some thing like that.

[Zope] Re: Question regarding changing Zope site to another distro
Hi Mário Now... I think my Zope is suffering from arthritis :( I can't undo any more, either in Zope nor Plone and i can't compress Zope's database without getting an error and... no database compressed. As if you care to rapidly browse the site, you will see it is indeed a small one, but the /usr/local/zope .bz2 tarball is already at 1 GB and increasing. Well, if you want somebody able to help you, you should post the error you got + a traceback. Does this sympthoms means that i'm going to have troubles now migrating to RHEL 4 ? Perhaps your Data.fs is corrupted or something like that. If I'm not wrong, there was a bug when packing the ZopeDB on that zope version. Somewhere on the zope hirarchy there is a script to repair this (look the archives). Anyway, if I were you, I would try to solve the problem before migrating and off course do a backup before trying something. Maintaining the Zope and Python version of course and the same scheme. I don't want to upgrade Zope, nor Python, nor Plone. You don't have to upgrade, but the new versions have some important bug fixes. I'm also using the same zope as you and I really want to migrate it.

[Zope] Re: Forcing all Zope access to come through an Apache/SSL proxy
Hi, I saw that others already answered to your question; however, they use the proxy module and you are using rewrite, which is what I use: IfDefine SSL VirtualHost YOUR_IP:443 ServerName your.domain.com ServerAlias your.domain.com *.your.domain.com SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /usr/local/apache/conf/ssl.crt/server.crt SSLCertificateKeyFile /usr/local/apache/conf/ssl.key/server.key RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/https/your.domain.com:443/VirtualHostRoot/$1 [P,L] /VirtualHost /IfDefine Note: this module also depends on the proxy module, but the sintax is diferent. Regards, Josef Reuven M. Lerner wrote: I've written a Zope application that needs to be behind SSL. I assumed that the most straightforward way to do this would be to (1) set up Zope on port 8080 and (2) use Apache to act as a proxy between the outside world and Zope. Unfortunately, while it was a piece of cake to set up a proxy for non-SSL access to Zope, I'm rather stumped regarding SSL. I've done non-SSL proxying for years with mod_rewrite, and it was really a snap, so I'm surprised that this is so difficult. Zope is working just fine when I access it directly (using HTTP) on port 8080. I have installed the (self-signed) SSL certificate into Apache without any trouble, and am able to access individual documents on disk via SSL, using Apache. So if all I would want is to use Apache with SSL, I would be done by now. Here is the relevant portion of the Apache configuration file (with names and numbers changed somewhat): VirtualHost 66.123.23.17:443 ServerName myserver.com ServerAdmin [EMAIL PROTECTED] SSLProxyEngine on RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/https/myserver.com:443/app/$1 [L,P] /VirtualHost The above should make it possible (I believe), an HTTPS connection between my browser and my cup. Apache should then take that incoming SSL request and issue its own request to the Zope server. Zope will respond, sending it back to Apache, which (in turn) sends it back to me. But of course, that doesn't happen. Zope's provides indicates that many of the requests begin with \x80g\x01\x03. My guess is that the SSL request is being piped to Zope directly, but it's hard to know from just a few characters. Does this mean that I need to do some more translating, from HTTP into HTTPS? Not that it should make any difference, but I'm running Apache 2.0.52 on Red Hat Enterprise 4.0, with Zope 2.7.5 and Python 2.3.4.

[Zope] Re: How do I logout using DTML
How do I logout current user using DTML
I used dtml-call expr=acl_users.logout(REQUEST) but it didn't work
and zope gave me this.
Site Error
An error was encountered while publishing this resource.
*Error Type: AttributeError*
*Error Value: logout*
**
*What did I do wrong??*
You didn't specify which user folder you are using and if, for example,
you use it with CookieCrumbler or other pluggins. If you use
CookieCrumbler, then you can expire the authentication cookies like
this:
dtml-call REQUEST['RESPONSE'].expireCookie('__ac', path='/')
dtml-call REQUEST['RESPONSE'].expireCookie('__ac', path='/')
I think a redirect is also needed, but I'm not sure.
If you aren't using CookieCrumbler, then you can try the method
described here:

[Zope] Re: How do I logout using DTML
Dear Allen, please post your replies to the newsgroup as well. I tried both yours and the dtml-raise methods, but both of them didn't work. With yours I redirect myself out but I still logged in. With dtml-raise Unathorized, it popped out an password query box and kept ask me to input password for three time and went to an error page and I'm still logged in as well. Did I do anything wrong?? The dtml-raise should work. I don't know why isn't workning for you. Perhaps you stored the password in the browser or something like that, try deleting the stored passwords. About the popup window and the error message, as Jens post in the other message you started, this is the normal behaviour and can't be avoided. One way I can think about solving this behaviour is storing a hidden input field like go_to_logout, then check the request in the standard_error_message when an unauthorized exception occures and close the window with javascript if such variable is found. I know that zope can access the variables on the request after an error happens, but I'm not I'm not sure if this is going to work with an UnauthorisedException. For the second approach with the authorization cookies, you first have to make sure that you have installed CookieCrumbler and that you have created an instance of it. After doing this, the expiration cookies method should work. Once you install CookieCrumbler, you can modify the default login forms if you want.

[Zope] Re: Opening .doc files in zope
The short answer is it depends. To make such files generally available you have to convert them to HTML so arbirary browsers can access them. You can use MS Word to do the conversion. If your Zope is running on a Windows machine that also has Word, you can manage the conversion dynamically using an External Method or a Product (which you'd have to write). Alternatively, you could store the MS Word document in it's XML form and use that to drive the rendering. If you are not interested in general availability and you users are all running Windows with Word installed, you can configure IE, I believe, to render Word documents directly. In addition, you could use the wmWare libraries to convert the word files to html/pdf, but they don't work well with complicated word documents. You can download there here: http://wvware.sourceforge.net - linux http://gnuwin32.sourceforge.net/packages/wv.htm - Windows Regards, Josef ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Hi Erik,

strings; their initiallized value.
very strange.
Looking at your python script I saw that initially you set error and
message to the empty string ''. I guess the script is not detecting a
'next_state' keyword in the request. So, it is excecuting the first if
of your code:
if not request.has_key('next_state'):
return container['MAIN'](context, request, error=error, message=message)
Where are you initializing 'next_state'? Try printing the request
object to see if it really exists or perhaps you are doing some typo.

Josef

You have three alternatives (perhaps four if you consider linux): First alternative: 1.1 Install the python 2.3.4 binaries (the python that comes with zope, isn't logged on the registry, so, you can't use it) 1.2 Install the the egenix binaries 1.3 Copy the egenix installed files to: C:\YourZopeFolder\lib\python If I'm not wrong, the binaries are installed on : C:\python2.3\lib\python2.1 - Make sure that you don't overwrite something in the zope's python. You can download the source code of egenix to have an idea of the files it installs 1.4 Uninstall python if you want Second alternative: 2.1 Create a folder called Python in C:\ 2.2 Create manualy this registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.3\InstallPath] 2.3 Set its value to C:\Python 2.4 Install the egenix binaries (they will be installed somewhere on C:\Python). 2.5 Copy the egenix installed files to: C:\YourZopeFolder\lib\python 2.6 Delete the registry key Alternatively to step 2.2, you can get this registry file: http://www.zope.org/Members/SmileyChris/HowTo.2005-02-06.0339/pil_for_windows_fakepython.reg Before double clicking on it, change the 2.1 by 2.3 in your preffered text editor. Then you can double click on it and it will automatically install the key. Be aware that the key will remain on the registry till you manually delete it. Third alternative: Install python from source and then egenix. Here you need a C compiler. Finally copy the egenix files to C:\YourZopeFolder\lib\python I hope this was usefull.

Normally you have to put them inside a i18n folder located in your product tree.

The only problem I see here is that you have to remmember it every time you update plone. I'm not sure if this would work: you could try to create a dummy folder, let's say MyTranslations, inside the Products folder of your instance.

[Zope] Re: NauScheduler problem
Hi Barry, I'm getting an attribute error when I try to run Zope 2.7.6, which is occurring when NauScheduler starts up: AttributeError: ignoreLater [...] schedule.ignoreLater() AttributeError: ignoreLater It means that the object schedule doesn't have or can't access a method called ignoreLater. With it can't access I mean that the object is there, but it is broken. Looking at the source code of the NauScheduler, I saw that the __init__.py file checks for an instance of the ScheduleList class, which has the same id and if I'm not wrong it is created the first time that you create a NauSchedulder object in the ZMI, then the absolute path of the new created object is added to a path list inside the ScheduleList object. So, it means that somehow you already tried to create a NauScheduler Object, but something when wrong causing either the creation of a broken object or the object wasn't created at all, but its path was stored in the ScheduleList. And I think that's why you get AttributeError: ignoreLater because None or a broken object don't have or can't access the ignoreLater method. So, my suggestion is: 1) Make a backup of your Data.fs 2) Remove the NauScheduler Product from your Products folder. 3) Restart Zope 4) Remove the NauScheduler objects 5) Remove the ScheduleList object. 6) Stop Zope 7) Move the NauScheduler again to the Products folder 8) Restart zope 9) Watch at the console to see if an error is printed 10) If no errors are printed, then try to create a NauScheduler object and see if it works. I am using NauScheduler on other windows and unix systems. But have not seen this problem before. Can anyone help? Below is the traceback. Another possibility is that you are using a Data.fs comming from a unix system into a Windows XP PC and somehow the import of the instances wasn't successful. If this is the case, the question is: did you make sure to first install all the products you are using in linux before moving the Data.fs?

That's because the user running zope doesn't have any root privileges and a external method is run as this user and not as root. Anyway, I just don't think it is safe to allow an zope admin user to create users in your operating system. What if your zope admin password gets hacked? Then the hacker could easily create a user in your machine and gain access to it as well. Why don't you do it directly by following the old way: logging in to the unix console, su to root and then calling useradd? Anyway, if you still want to do this, then you have to use sudo as Andreas said. Other alternatives would be: 1) Run zope as root. 2) use set-user-ID or set-group-ID (man chmod) with a C binary that calls useradd 3) Add your zope user to the group of root.

The message is also different, but it could be related. Anyway, just in case you migrated from zope 2.5.x to 2.6.0, you could try: http://www.zope.org/Members/jmeile/upgradingZope I don't know if this also affects versions 2.6.0 because by that time there was only 2.6.0/2.6.1 available. This small article assumes that you still have your Data.fs from the old zope instance. If not, the only thing I could think about would be to downgrade, check that everything works, and then upgrade following the instructions - I'm not sure if this may work; I've never done such thing, for I always keep a backup of my old Data.fs By the way, before doing anything, make a backup of your Data.fs file and then try the instructions. It could be also that you forgot to install a product you used in your old zope into the new one, assumming again you were migrating. So, check the products folder. By the way, posting your zope version, whether you migrated or not, and the previous version you had before migrating would be useful in order to get more help from the list.

[Zope] Re: Cookie Crumbler
Hi Infor,
I found that my weakness is that I am DTML scripter. After printing the Cookie
Crumbler source code,
I need some help/advice as how to access the Cookie Crumbler methods
or api from DTML. I have searched
the Zope documents however have found none that can help.
I would appreciate some advice or pointers.
Thank you.

I have a trying time using Cookie Crumbler 1.2 with Zope2.8.4 (windows version).
I could NOT figure out how to log out a user. I have simplified to the orginal
logged_out form to this:
dtml-call RESPONSE.expireCookie('__ac_name')
a href=/manage_zmi_logoutlogout/a
Except for the /manage_zmi_logout part, I'm using some similar
script. I'm using it on zope 2.6.4 and it works. I don't know if
it works in 2.8.4. Anyway, here it is:
dtml-call REQUEST['RESPONSE'].expireCookie('__ac', path='/')
dtml-call REQUEST['RESPONSE'].expireCookie('__ac', path='/')
Note: Yes, I expired the cookie twice. If I'm not wrong, I recall to
have had problems with only one call (Not sure).

[Zope] Re: Zope User in Apache Logs
Dear list,
I've been going through the list archives looking for tips on logging
(getting sensible statistics from my log files).
At the moment I have the setup recommended by most posts, namely
multiple Apache virtual hosts that proxies requests to a single Zope
instance.
I would like to know how I can get Apache to log the current Zope user.
Here's an example from my Apache access_log:
10.0.0.100 - - [02/May/2006:15:32:18 +0200] GET / HTTP/1.1 200 35721
Which results in this entry from my Z2.log:
127.0.0.1 - adp [02/May/2006:15:32:21 +0200] GET
/VirtualHostBase/http/mysite.com:80/vhosts/mysite.com/VirtualHostRoot/
HTTP/1.1 200 36054 Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US;
rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2
The current user is logged by Zope, but not by Apache.
Is there a way to make Apache aware of who is logged in through Zope?
I'm also trying to do the same thing. I want either to modify the zope
log in order to show the real user IP and replace the referrer by the
one the user typed in the browser (without everything between
VirtualHostBase and VirtualHostRoot) or just return the authenticated
user to apache.
I read the answer from Dieter and unfortunately I'm not authenticating
from Apache. So, I went for the approach indicated by Chris Withers
without any success:
If your Zope auth solution can put a header in the http response,
then you can use a custom apache logging directive to put this in your
Apache log in place of what it thinks the username is.
I put this on the log method of the medusa/http_server.py file:
self.response.setHeader('remote_user',name)
and set my apache access log like this:
CustomLog /home/apache/httpd/logs/access_log combined
The combined log is defined as follows:
LogFormat %h %l %u %t \%r\ %s %b \%{Referer}i\ \%{User-Agent}i\
combined
There you see the %l and %u directives, which are the Remote logname
and the Remote user.
But apache still doesn't get the zope authenticated user. So, Chris, do
you remember what header you set, where, and which method you used?
On the other hand, I also tried to do it the opposite way: modify the
zope log in order to show the real ip address and remove every
VirtualHost info from the referrer. I achieved the first part by using
the following patch:
http://www.zope.org/Collectors/Zope/1732
Then I tried the following in the log method of the
medusa/http_server.py file:
referer=getattr(self,'VIRTUAL_URL_PARTS',None)
#I tried this as well
#referer=getattr(self.request,'VIRTUAL_URL_PARTS',None)
if not referer:
referer=self.get_header('referer')
if not referer:
referer=''
else:
referer='/' + referer[1]
But it seems that I can't access the 'VIRTUAL_URL_PARTS' key. How can I
get this information?
Thanks in advanced,
Josef

Ok, Answering to this question. I guess I had to set the header inside the
authenticate method of the BasicUserFolder class. Here is what I did:
def authenticate(self, name, password, request):
emergency = self._emergency_user
user = None
if name is None:
pass
else:
if emergency and name==emergency.getUserName():
user = emergency
else:
user = self.getUser(name)
if user is not None and user.authenticate(password, request):
pass
else:
user = None
logUser = 'Anonymous'
if (user != None):
logUser = user.getUserName()
request.response.setHeader('remote-user',logUser)
return user
The header is set, but apache still doesn't get it, so, I guess I'm
using the wrong name. What header should I use?

the correct authenticated user.

[Zope] SSL Redirect for CookieCrumbler
Dear Zopers I need to redirect all my http requests to the login_form of the CookieCrumble to https, so, I wrote this rule in apache: RewriteRule ^/login/login_form(.*) https://server/login/login_form$1 [NE,L] It authenticates me through ssl, but then it cames back to http. I saw that the problem is that the came_from variable refers to the original http request; something like this: https://server/login/login_form?came_from=http%3A//server/pageretry=disabl e_cookie_login__=1 Is there any way of writing something like this in apache? RewriteRule ^/login/login_form?came_from=http%3A(.*) https://server/login/login_form?came_from=https%3A$1 [NE,L] It is not working for me :-(. I even tried escaping the '%' with a backslash like this: RewriteRule ^/login/login_form?came_from=http\%3A(.*) https://server/login/login_form?came_from=https%3A$1 [NE,L] But Apache doesn't match the rule. What's wrong with that? Anyway, another thing that bothers me about the last approach is that I even don't know if there is always a came_from variable. Is this always the case? Is there any other way of achieving this?

[Zope] Re: SSL Redirect for CookieCrumbler
I need to redirect all my http requests to the login_form of the
CookieCrumble to https, so, I wrote this rule in apache:
RewriteRule ^/login/login_form(.*) https://server/login/login_form$1 [NE,L]
It authenticates me through ssl, but then it cames back to http. I saw that
the problem is that the came_from variable refers to the original http
request; something like this:
https://server/login/login_form?came_from=http%3A//server/pageretry=disabl

Ok, finally I found a way of correcting this behavior without modifying
my original RewriteRule. I added a new boolean attribute to the
CookieCrumbler class: ssl_redirect. If it is set, then the http Part
in the came_from variable will be replaced by https. All this would be
done inside the getUnauthorizedURL method of the CookieCrumbler class
(See the attachment).
If you think there is a better way of doing this, please let me know.

[Zope] Re: SSL Redirect for CookieCrumbler
Hi Chris, I need to redirect all my http requests to the login_form of the CookieCrumble to https, so, I wrote this rule in apache: Why bother? Just because the form is secure doesn't make cookie authentication any more secure. Yes, you're right. That is exactly the conclusion I also figured out after finding an interesting article in plone.org, which talks about this: * Secure login without plain text passwords http://plone.org/documentation/how-to/secure-login-without-plain-text-passwords The only Problem is that the product mentioned there, SessionCrumbler, is based on the CMF CookieCrumbler and not the Standalone version. I guess it wouldn't be difficult to port; I even tried it by replacing the CMF imports by the Standalone version, but it didn't work. Zope hangt and I even didn't get a TraceBack. Anyway, I'm not going to spend more time trying to get this working. I will perhaps try to do some patch to the basic http authentication like CookieCrumbler does, but instead of showing the login forms, I want to do a redirect if the request is insecure, so, you will still get the popup window, but in https. Do you say in https once authenticated? Yes, the problem, if you read my post was that with the apache RewriteRule, I could authenticated myself in ssl, but after that the browser took me back again to http - See the article; it exposes clearly the problem.

Hi Oliver You can also look inside the logs of your Apache for the IP addresses?! That's not always possible in our virtual hosting environment, and besides it makes no sense to have to look in two different places for the same information. I would also look for that information in the apache logs as Andreas suggested. The problem if you patch the zope code to show the ip addresses in the zope log, and your zope webserver is under a firewall, then you won't know if your firewall is working or not.

[Zope] Re: Change language with PTS
Hi Peter,
First at all, I think Localizer may be easier to do this task, it has
Built-in Cookie and traversal url support. You may also define your own
language selection method. If you still want to try this with PTS, then read
the following lines.
Now, perhaps this works if my browser setting was 'sv' but it isn't. I
actually don't want to use the browser setting at all, I want to
control with via my own cookie and url traversal stuff.
To set the language you want with PTS, you have to set the
HTTP_ACCEPT_LANGUAGE as follows:
REQUEST.set('HTTP_ACCEPT_LANGUAGE',lang)
where lang could be 'sv'. Please note that you have to do this at the
beginning your your ZPT Template or DTML method. I have had problem when
doing this in the middle of the code.
I think cookies could also work, but I haven't tested the code myself. You
will need to set them via the request object like this:
REQUEST.RESPONSE.setCookie('lang','sv', max_age=something)
lang = REQUEST.cookies['lang']
PTS doesn't support traversal url. Anyway, you can still achieve this with
Access Rules. There is an outdated how-to that can give you an idea on how
to do this:
How To build multilingual sites with SiteAccess:
http://www.zope.org/Members/jdavid/MultilingualSiteAccess
There you will see that SiteAccess is mentioned, which is deprecated;
however, I think this Product was replaced by SiteRoot and Access Rules
(somebody correct me if I'm wrong). You may need to google about this.
As mentioned in that How-To, it was superseded by Localizer, so, you may
look at the source code of this product as well.

[Zope] Re: Change language with PTS
Hi Chris, Don't use PTS! Only if using zope 2.8.x, which indeed I'm using, for we have a 3rd party product that depends on that. Anyway, an update will be done, so, I will follow this advice. If you have a google, you'll see i've just recently done the language-selection-from-cookies dance in Zope 2 but using Zope 3's infinitely better translation machinery ;-) Yes, I googled a little bit and it looks promising. I even did a small example, which luckily worked. There's even a sx.translations package which will help with providing you with a list of languages to pick from... Lemme know if you want me to release it once you've had a read of the relevant threads... I searched that thread and the references there helped me a lot with my small example. Google even now how to spell your last name ;-), but I don't. Anyway, for the interested here is the thread: * Zope 2.9 and Zope 3 i18n, more questions... http://mail.zope.org/pipermail/zope3-dev/2006-June/019496.html The article by Philipp von Weitershausen, which is mentioned in there, is really useful. The examples of his website are even better. I'm not the OP, jet I would be also interested in your product. I'm not planning to use the zope3 translation yet, but I want to experiment a little bit.

[Zope] Running scripts after zope startup
Hi,
I'm working in a configuration module for other products I'm developing.
The idea is that the user first has to make an instance from this
product, then define there where the other products instances will be
created, what header, footer, and style sheets they will use, etc..
The configuration product has to detect which of my products are
installed, then load some xml Formulator forms. I just created a
registry class that to do the detection process:
import Products
JM_PRODUCTS = ['JMConfigurator','JMPlace','JMPerson']
class JMRegistry:
def __init__(self):
availableJMProducts = {}
for productName in JM_PRODUCTS:
productModule = getattr(Products,productName,None)
if productModule is not None:
availableJMProducts[productName] = productModule
self._AvailableJMProducts = availableJMProducts
More methods come here
...
JM_Registry = JMRegistry()
The problem here is that if I import this in the initialize method of my
configuration product, the _AvailableJMProducts dictionary is empty
because at this point the other products hasn't been jet registered by zope.
I just thaught about something like the StartupScripts products does:
running this after zope starts. This is achieved as follows:
__init__.py from my product:
from Products.JMUtils import JMRegistry
def initialize(context):
#Some registration code comes here
#...
import ThreadedAsync.LoopCallback
ThreadedAsync.LoopCallback.register_loop_callback(
JMRegistry.createRegistry)
JMRegistry.py:
JM_PRODUCTS = ['JMConfigurator','JMPlace','JMPerson']
class JMRegistry:
#Class definition is the same as above
#...
JM_Registry = None
def createRegistry(args *):
JM_Registry = JMRegistry()
Unfortunatelly, after seeing the zope source code, I saw that the
ThreadedAsync is only used by ZEO, which I'm not using.
My workaround was to call this in the __setstate__ method of my
configuration product as follows:
from Products.JMUtils import JMRegistry
class JMConfigurator(ZCatalog):
#__init__ and other methods come here
#...
def __setstate__(self, state):
ZCatalog.__setstate__(self,state)
if JMRegistry.JM_REGISTRY is None:
JMRegistry.JM_REGISTRY = JMRegistry.JMRegistry()
#After having initialized the registry, I can call the methods to
#load the Formulator forms
self.LoadFormulatorForms()
This works well, but I think it is not the better place to define this
kind of things. Is there any better way of achieving the task?
Regards
Josef

[Zope] Re: How to do...[Rendering zpt on the fly]
Hi Garito, I saw in another thread you still need this. If I'm not wrong what you are pretending is to somehow render zpt on the fly. So, here is my idea: I would like to write things like: object.property = 'here/anotherproperty' object.anotherproperty = 'Barcelona' and ask it like: print object.property - 'Barcelona' or tal:city tal:replace='here/property' / - 'Barcelona' Is this possible? I think you could perhaps create a new class to store the tal expression attributes, let's say you called it ExpressionAttribute. This class must be callable and be able to evaluate tal expressions. This is a small sketch of how I think it should look like: from Products.PageTemplates.ZopeTemplate import ZopeTemplate class ExpressionAttribute: #Here I also assume that you only enter the expressions #without html and the tal part, like: 'here/property' #Please also noticed that all sintax errors in your zpt #code must be catched somewhere def __init__(self, id, talExpr): self.talExpr = 'span tal:replace=%s/' % talExpr #I'm not sure about this, but I think it will create a Template on #the fly. self.zpt = ZopePageTemplate(id, text = self.talExpr) #Note: I really don't know if you have to pass other parameters to #pt_render, ie: the container of your property. You will have to test #this. def __call__(self): return self.zpt.pt_render() Then, in the __init__ of your zope product you will need to do things like this: class YourProd(...): def __init__(self,prop1,prop2,prop3,...): #This is a normal property self.prop1 = prop1 #This two are tal expression properties self.prop2 = ExpressionAttribute(prop1) self.prop3 = ExpressionAttribute(prop1) Then, I guess you can call it as: yourProdObj.prop3 or in tal: here/prop3 I'm not sure about what I wrote and if this is what you are looking for. I just hope it helps.

[Zope] Re: TimeError in Zope 2.8.5
import time time.localtime(106900545747.045975).tm_year 5357 Now, we understand: it's the Python time implementation that has changed. With Python 2.3.3 (under Debian Sarge), we get: from time import localtime localtime(106900545747.045975) (1901, 12, 13, 21, 45, 52, 4, 347, 0) localtime(106900545747.045975).tm_year 1901 In my python 2.4.3 (compiled from source) and the one installed with the OS, which is also 2.4.3, it doesn't work. I get: Traceback (most recent call last): File stdin, line 1, in ? ValueError: timestamp out of range for platform time_t So, I guess there should be something that you can configurate when building python, or it is perhaps a linux kernel paramater. With python 2.3.5 it works however, so, it is a change in python as Dieter mentioned. By running the zopectl in debug mode for zope 2.9.4, the resulting traceback is the same as the one posted by the OP. With zope 2.8.8 it runs without any problem. So, it could be that the provider is running zope 2.8.5 with python 2.4.

You have to make sure they don't concatenate normal strings and unicode: This is really difficult to debug. I think that the i18n:target directive is only useful you want to show a text in a zpt which must be always rendered in the same language (ie: some governmental entities shows first an English version of a official document, then immediately above there is a version let's say in spanish).

[Zope] Re: Zope newbie.... unicode problem
Hi Tyler
When serving a web page, we get an error that involves the
fetching and display of a document to the browser. Evidently,
it's choking on some unicode bytes when it's expecting plain
ascii.
I'm assuming it's
/usr/lib/zope2.7/lib/python/Products/PageTemplates/PageTemplate.py
that's causing the problem as the data isn't somehow massaged correctly
before processing arrives at /usr/lib/python2.3/StringIO.py line 203.
So, you are using zope 2.7 and for the location I guess it is a binary.
I don't know if the bad byte is in a zope template, document, or
a database record that it's fetching. I do believe this installation
of Zope uses Plone... but I've no idea whether Plone is somewhere
used in the error stream of all the different calls.
Do I need to post more information? Tell me .. and I'll get it.
Yes, perhaps you could post the template generating that error. If it is
really long, try to localize the problem by removing parts of the
template and test it continuously till you find the offending code.
Recently I got some similar problem. I'm using zope 2.8.8 and I taught I
was affected by this issue:
http://www.zope.org/Collectors/Zope/2180
However, after adjusting that patch for 2.8.8 (it is for 2.10), I was
still getting the problem. Then I figured out that somewhere in my code
I was getting the title from an object and comparing it with an unicode
string. The title turned to be a normal string with unicode parameters. ie:
a = u'This is unicode \xc3\xa4\xc3\xb6\xc3\xbc'
#this has unicode characters äöü, but it isn't a Unicode string
#Note that the u' is missing
b = '\xc3\xa4\xc3\xb6\xc3\xbc'
#This will fail
print a == b
#This is what you need to do
a = u'This is unicode äöü'
b = 'This is ascii'
print a == b.decode('utf-8')
I was doing that in a python product, so I could do this:
from types import StringType
if type(b) == StringType:
b = b.decode('utf-8')
I don't know if you can do that in zpt. You also have to know which
encoding you are using. In my case it is always utf-8
You may also trying to see if your plone version supports your zope
version, which is old (Open the README or INSTALL file).
Try also to upgrage your zope. Perhaps this will solve your problem.

Josef

In the first case zope will scan the folder hierarchy till it finds a folder where the permission is defined. In the worst case it will reach the root folder where the permission must be either enabled or disabled.

Install a separate python that is used only by your zope instance. Use
setdefaultencoding only there.
This is nonense. A custom sitecustomize.py script does the job without
installing a complete new Python.
You need to read a previous reply:
I set it global in sitecustomize.py under
/usr/lib/python2.4/site-packages and then
dtml-var MessageCatalog('Hallo Welt!')
works. Now I only must find the right place for setdefaultencoding() so
it only affect my zope-instance.
For the path used there /usr/lib/python2.4/site-packages, it seems
that the python used by zope is a binary that comes into a rpm package,
so, this may break some things on the OS. So, I guess a new python for
only zope makes sense here

[Zope] Re: How to upgrade Python in older Zope?
Hi, You could try to install an oficial python 2.1.x release from python.org, then change the python's path in the runzope.bat script. I work mostly with zope under linux, so, I haven't tested this, but perhaps it works. Another problem you may face is that perhaps the official python binary may also don't have large file support. On that case, you will have either to search if somebody provides one with LFS, build your own python (and zope probaby) from sources, or as somebody said, use a newer zope binary release, which will require you to upgrate your Data.fs. Best regards Josef Tit-Liviu Leontin schrieb: Folks, I desperately need support for large filesystem so the data.fs file can exceed 2 GB.

From what I've read, the issue is with the old Python not having LFS enabled, so I thought I'd just upgrade it to 2.2.3 which has LFS enabled. The question is, how do I do that?

[Zope] Re: Appending to a file via manage_edit?
I've been looking around for this, but can't seem to find anything. I'm assuming that it is just not possible, but thought I'd ask just in case. For File objects, I see that manage_edit() has the parameters: title, content_type, precondition, filedata REQUEST. Setting something in the filedata parameter will replace the file's current data with that. This implies (to me at least) that the only way one can edit a file is a complete rewrite. Does there exist a way to simply append data to the end of the file? For instance, if one wanted to write to a file line by line, is that possible in Zope? out-of-the-box: NO Appending data would require the manipulation of the linked list of Pdata elements. There is no API for this available...so basically forget it. What about the python pickle/cpickle and marshal modules? If I'm not wrong zope uses cpickle to append data to the Data.fs, or am I wrong? I haven't read the module documetation deeply, but as I understand, pickle/cpickle is used for serializing python objects, while marshal is for binary data. http://docs.python.org/lib/module-pickle.html http://docs.python.org/lib/module-marshal.html Anyway, you still need to load the whole file into a temporal memory.

BTW - I'm using ZPT, not DTML. I'm guessing I can do this with a simple script that I include on every page, yes? That could work, but seems a bit error prone - that's why I'm looking for some sort of request hook. But maybe that's my best option within Zope. Thoughts? I guess if you want to do this easily inside zope, then a script is the way to go. Somebody already posted a dtml solution; however, I think it is better you put it in a python script that will be called from your standard_header file, which can be either a dtml method or a page template. A request hook will require you to patch zope, write a monkey patch, or some kind of UserFolder based on ip addresses, which means to directly modify zope's code or create an external product. The invested time on doing this isn't worth, when you can do it easier and in less time, with either a script or by modifying your proxy's configuration. I think it would be better to let your proxy do this. This isn't really hard with nginx: http://wiki.codemongers.com/NginxHttpAccessModule Anyway, if you don't have access to the maschine hosting your zope, then you should try the script solution.

[Zope] Conditional dtml-boundary in dtml-sendmail
Dear list
I'm trying to send a multi-part email after having submitted a
form. In that form, the user will give some basic information
from him, then he will be able to send at most three files.
This is my dtml-method to send email after having submitted the
data:
dtml-let email=REQUEST.get('aba_email_txt').encode('utf-8')
name=REQUEST.get('aau_name_txt').encode('utf-8')
lastName=REQUEST.get('aat_vorname_txt').encode('utf-8')
company=REQUEST.get('aas_firma_txt').encode('utf-8')
file1=REQUEST.get('aap_dateien_anhang_dat')
file2=REQUEST.get('aaq_dateien_anhang_dat')
file3=REQUEST.get('aar_dateien_anhang_dat')
dtml-sendmail smtphost=my_host.my_domain.com
To: [EMAIL PROTECTED]
From: dtml-email;
Subject: Anfrage dtml-name; dtml-lastName; - dtml-company;
Content-Type: text/html; charset=utf-8
dtml-mime type=text/html; charset=utf-8
html
body
Some html code comes here
/body
/html
dtml-boundary type=application/octet-stream disposition=attachment
filename_expr=file1.filename
dtml-var file1.read()dtml-boundary type=application/octet-stream
disposition=attachment
filename_expr=file2.filename
dtml-var file2.read()dtml-boundary type=application/octet-stream
disposition=attachment
filename_expr=file3.filename
dtml-var file3.read()/dtml-mime
/dtml-sendmail
/dtml-let
Let's say that the user doesn't submit file3, on that case, zope will
generate something like this: some_ramdom_id.dat and it will attach
an empty file. I tried something like this:
dtml-if file1.filename not in ['', None]dtml-boundary
type=application/octet-stream disposition=attachment
filename_expr=file1.filename
dtml-var file1.read()/dtml-if
However when I try to save, zope fails and says:
Error Type: Document Template Parse Error
Error Value: Unexpected tag, for tag dtml-boundary
type=application/octet-stream disposition=attachment
filename_expr=file1.filename , on line 215 of sendAnfrage
The only way I found to cope with this was doing a script to validate if a
file has whether a name or not, then I will return a dictionary like this:
{'name': real_name_or_dummy_name, 'data': file.read()_or_dummy_text}
So, I feed the boundary with a dummy file when no file was uploaded. I don't
really like to send dummy files since it may confuse the person receiving
the emails. Is there any better way of achieving this? Please note that
since I'm working in the zmi and I'm not the administrator of the machine
where my page is hosted, I can only use dtml to send mail :-(, thus using
the python mail library isn't an option on this case.

Josef

I started shivering while reading your code. We would have written such code five or six years ago - because we had no other choice. Please use the standard 'email' module of Python...this just works and you don't need to write such ugly and error-prone DTML code. Yes, I know it is ugly and I would like to use python instead, but as I said before I can't use the email module of python since the Machine were the page is hosted isn't administrated by me, so, there isn't any change of allowing or installing a python module. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Re: Conditional dtml-boundary in dtml-sendmail
The 'email' module is part of the standard Python distribution since generations. Well, I said allowing or installing. I wasn't sure if it was and with allowing I meant by using allow_module or allow_class. I guess you can't just use this module without removing security assertions.

[Zope] Re: Conditional dtml-boundary in dtml-sendmail
Tom Von Lahndorff wrote: How is dtml more error-prone than python? I'd imagine that all depends on who's authoring it. In this particular example, python's email package has a very OO approach to generating emails. Yes, that's what I hate from the dtml thing; it looks ugly :-( The DTML approach relies on you remembering to put in the right statements for the right constituent email parts in the right places. It's easy to make mistakes and generate emails that won't work with most clients. It's also harder to generate emails with the correct headers (Date, Message-ID, etc) than it should be, so you're more likely to pump out email that mtas consider to be spam. Actually, I did several mistakes: first, if you include a blank line just after finishing defining the email settings, ie: To, From, Content-Type, etc, you will get your email, but in a format that you can't read. The second problem was with the unicode: first I got the characters wrong on the email subject, but on the mail's body were ok, then I change something and got them good on the subject, but on the body non-ascii characters were dropped. After lots of testing, I finally saw that you have to define content-type everywhere: on the mail headers and also on the text-mime contents. Then you have to encode all your strings to utf-8. The DTML approach also makes attaching files a living hell... Yep, I agree on this. You can't dynamically set the number of attachments and even if you don't submit a file on your form, zope will send an empty file with a strange name. Well, I guess I will do an external method on my own server and then try to convince the people owning the machine where the page is hosted to include it. Otherwise, my last resouce would be to embebbed the content on a iframe or call an external link to my server. Thanks anyways for your replies.

[Zope] Re: Conditional dtml-boundary in dtml-sendmail
The email library should be available to use with a Script (Python) and
can be done all within the ZMI. Otherwise maybe use dtml-try?
Well, I should have mentioned this: the zope installed on the server is
2.8.x. Yes, it is old, but it is because all the page uses an own CMS
based on silva, which isn't compatible with newer versions.
I tried this:
import email
and it worked; however, as soon as I tried this:
from email.MIMEText import MIMEText
msg = MIMEText('Sending mail through python module')
or
import email
msg = email.MIMEText.MIMEText('Sending mail through python module')
An Unauthorized exception comes. So, I guess MIMEText is protected at
least on 2.8.x. But I guess in 2.11.x is protected as well, or am I
wrong?
Thanks for your reply. I guess there is no way of achieving what I want
on dtml, so, I will try to do it an external method and try to convince
people there to store it on the server or I will have to do it on my
own server and embebbed it on an iframe or call an external link.

[Zope] Re: authentication with python program
Hi Miguel
First, you could drop the Unauthorized Exception from the error_log
object in the root folder of the zope management interface. Then
activate the verbose-security option in your zope.conf file. To do
this, you need to put/replace this lines:
security-policy-implementation python
verbose-security on
After you have done this, you need to restart zope, try again your
authentication script, and take a look at your event.log file or
the error_log object. You may find the reason of why is this failing.
In case you don't find it, then place the full traceback here.

Re: [Zope] how suppress http based authentication window of zope
Hi, CookieCrumbler worked fine for me on the past. The only thing that's up-to-you is to customize the login form if it doesn't fit your needs. Perhaps the only issues I see on CookieCrumbler are: 1) Even if you redirect your login_form to https, the came_from variable, which is set when you arrive to the login_form page, will redirect you to http. In order to fix this, you have either: a) Change the came_from variable to https. I did some patch on the past, however, since I personally don't like cookies, I'm not using it nor having tested it recently. See this post: SSL Redirect for CookieCrumbler http://mail.zope.org/pipermail/zope/2006-June/166799.html Please note that you need an apache rule to redirect all http requests to your login_form to https. b) Force that zope authentication is always done in ssl. I also did a product, but I have only tested it with http authentication. I think it may also work with the CookieCrumbler: JMSSLBasicAuth http://www.zope.org/Members/jmeile/JMSSLBasicAuth With this product, no apache rule to redirect to ssl is needed. Nevertheless you still need the apache ssl module to define your https virtual host. 3) Cookies are somehow stored on the hardisk. I don't know how CookieCrumbler manages this. That's why I forget about them and keep using http based authentication through ssl. Anyway, an alternative would be the SessionCrumbler product; It also stores a Session Cookie, but it will be ramdom and expire at sometime. However it depends on Plone, but I guess it won't be difficult to port to plain zope: http://plone.org/products/sessioncrumbler Best regards Josef vaibhav pol schrieb: Dear All, As per my information zope provide http based authentication and not support cookies based authentication .

Hi, Thank you for replay . yes I know that product is using cookie based authentication.I want to know that is any work go around to support zope cookie based or form based authentication. Well, I think it won't be included to zope source code. Why to do it? There is already two products for that: CookieCrubmbler and SessionCrubmbler. I also I used CookieCrubmbler for Cookie based authentication. It Modify the request and server response and edit the header but because by using that we can suppress login window of browser but at the time logout it not modify the server response server send the Basic Authentication with 401 code . By seeing that browser kill user session I want is any other way to kill user session. means by sending any response or can i kill user session I just don't know if this is correct, but as I understand, at the logout time, what the CookieCrumbler does is to reset the authentication cookies. I used it on the past and it worked. I don't know what problem are you having. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

2) is it possible to tell zope NOT to store some things in the database (for instance in zope.conf-I've looked but not too closely and found nothing) Why don't you run a cron job that packs the database, let's say each month? You could also do a backup before packing; just in case you want to undo something later. Something that would be nice, would be to be able to store transactions in a separate file before packing, but I don't think it is posible in Zope. You may have to write something to do this.

Huh? not sure what you mean... if you keep the .old file created during packing, that has all the transactions in it that would have been packed away... I was just thinking about only keeping a log file with the transactions without the data and let's say apply it to a packed Data.fs. It was just a nice-to-have idea, nothing else. But I think for the OP would be enough to keep the Data.fs.old as you said. ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
