You can use configure --prefix=/path/to/dir to install (at least Zope 2)
into a custom location. This might also work for Zope 3. In addition
you must adjust the ports in etc/zope.conf (for Zope 2) in order to run
multiple Zope instances on different ports.

It should be enough to give only to Manager the permission

View and Access Contents Information usually do the trick.
If not, google for VerboseSecurity - a great add-on product
that will help debug security issues.

Unfortunately VerboseSecurity seems not to work on Zope 2.7.5-final.
I think there are some security issues by my ZCLasses used within the

Re: [Zope] newbie question

2005-05-24 Thread Phillip Hutchings
 I modify utils.py, after saving a copy, in order to
 obtain diagnostic output.  Then I delete utils.pyc,
 after saving a copy, in order to force a recompile
 (even used compilezpy.py for this a couple of times).
 Zope never seems to use the new version.

Restart Zope. Python will pick up the changes. Also, if you're
modifying security code, make sure you set
security-policy-implementation to Python in zope.conf, otherwise
you're using the C one, and no matter what changes you make to the
Python scripts you won't see any changes.

 I suspect that I have a fundamental misunderstanding
 of how Zope uses code in the Products directory.
 
 Is Zope storing all the compiled byte code in the
 data.fs file?  Is there a way to force Zope to use new
 code?

No. Refresh the product or restart Zope.

 Also, the previous developer removed the Control Panel
 putting Plone as the root of everything.  How can I
 get information that the Control Panel usually
 provides?

Find a heavy object, find the developer, bring the two together at
speed. Repeat until the problem is fixed.

yoursite/manage will get you to the control panel. If he's managed to
override /manage then you have problems...

And the real problem:

 TypeError: can only concatenate tuple (not list) to
 tuple

Like it says, you're supplying a list, you want a tuple. It looks like
you need to update PluginIndexes, I don't know where they come from.

Thank you Phillip.  I modified the zope.conf file as
you suggested and did

sudo ./zope stop

... usual msg

sudo ./zope start

... usual msg

Then generated the error.  The error log shows the
same output as before.  Not only should the line
number be one higher, I also put a dummy variable name
on that line to generate a stupid error msg.

How can it not be getting to that code?  I've searched
for another Zope instance, but found none.

Also, you are saying that I probably will never get
the Control Panel back on this site with Product
Management tools; no Product refresh then, I suppose. 
I'll have to thank the previous developer, as you
suggest!  (of course there is no documentation either,
arrgh!)

If you can think of anything else, I'd appreciated it.

Thanks.

If the /manage URL has been overridden it's probably possible to fix

It doesn't look like a monkey patch. Those aren't invisible in tracebacks.

Follow the code path higher until you do get some effect.

I would imagine it's some sort of redirect. I would start with using the 
IP address: usually this is enough to avoid the redirect. Otherwise, 
find out how to turn access rule off. I think this may be in 
Zope/doc/SECURIY.txt.


I don't think it's possible to really remove the Zope Control Panel.

I've seen odd things before, but I agree, it isn't likely that it's a
monkey patch. Chances are that some product is outdated.

You can't overwrite the manage URL with Zope, it's just not allowed. I
suspect there's some external URL rewriting happening here. Either
that or the guy was a real PITA and rewrote Zope to work with his pet
ideas.

 I'm trying to figure out Zope (on a time crunch, too), and I'm wondering how
 to do something.  How can I access HTTP variables in my DTML code?
 Specifically, I want to return code specific to the user's browser.  I know
 that HTTP has provisions for determing browser version, are those accessible
 in DTML and how?  If they are not accessible in DTML, is there a workaround
 (without oodles of javascript)?

these variables are part of the REQUEST namespace.
Specifically you can do

dtml-var "REQUEST.HTTP_USER_AGENT" to display the browswer
version. Creating conditional code is left as an excersize
for the student.

If you want to display a complete list of all HTTP REQUEST
variables, try this:

dtml-var REQUEST

 Another quick question:  I see that Zope 2.3 will have "Script" objects.
 What's the closest I can come in Zope 2.2.5?

 No, that's the problem. The icon isn't a broken box, but a regular

 TinyTablesPlus, a Help document; when I open that, it tells me that
 there are no items in TinyTablesPlus. So Zope seems to be seeing the

 Is there some setting that I need to change?

 Sorry to be so dense. It's tantalizing to have all this power so

Re: [Zope] Newbie question - Link between Methods based on Authorization

2000-12-19 Thread Oliver Bleutgen

 I am still newbie in Zope, so my question may be stupid - sorry.

 I have problem with access to method. Example - There are two methods: A
 and
 B. Method A contains common information, accessible for all user (include
 anonymous). Source code in method B updates data for method A and access
 for
 method B is restrict only for users with roles "AdminTables". There is a
 link from method A to method B in the code of script A, and this link is
 viewable for all user (also for anonym). After click on this link, user is
 asked for authentication. So there is no problem, but HOW MAKE THIS LINK
 VIEWABLE ONLY FOR USER WITH AUTORIZATION FOR OBJEKT B ???

Try

http://zdp.zope.org/projects/zsnippet/snippets/DTMLContent/PermissionContent

and zdp.zope.org in general.

cheers,
oliver

Hello Michal,

This may work:

dtml-if "AUTHENTICATED_USER.has_role('AdminTables', this())"
 a href="/link/to/method/B"Method B/a

Re: [Zope] Newbie question: adding a tinyTables object

2000-12-18 Thread Peter Bengtsson

Go to the Control Panel and click on Products. The TinyTable product is probably going 
to have a little "broken box"-icon. 
Click on it and wish that it will tell you the error so that you can fix it.

Good luck, Peter

 I'm running Zope on a Win98 machine; downloaded, unstuffed, and 
 installed tinyTablesPlus folder in the lib\python\Products directory. 
 TinyTablesPlus shows up in the product list of the 
 Control_Panel/Products folder of my Zope installation. But it does 
 not show up in the Available Objects pull-down menu in my Zope 
 content folders. I can't figure out how to Add a TinyTables object.
 
 Can anyone help?

Re: [Zope] Newbie question: adding a tinyTables object

2000-12-18 Thread Richard Blumberg

No, that's the problem. The icon isn't a broken box, but a regular 
product icon. Clicking on the link shows that there's one item in 
TinyTablesPlus, a Help document; when I open that, it tells me that 
there are no items in TinyTablesPlus. So Zope seems to be seeing the 
product, but not adding a TinyTable to the list of Available Objects. 
Is there some setting that I need to change?

Sorry to be so dense. It's tantalizing to have all this power so 
close at hand, and not be able to access it.

You schould never do so. Unquoted variables in SQL-statements are high

send a string which ends a statement and begins a new one, like drop

Instead reference only an index of a list with the columns to sort.

oder by dtml-sqlvar orderindex type=int is also a solution.
The index ranges from 1 to number of returned values.

 You can change the properties of an object in DTML by callling its
 manage_changeProperties method, for example:
 
 dtml-call expr="foo.manage_changeProperties(bar='New Value')"
 
 will changes the value of foo's bar property to 'New Value'.
 
 There are several ways of getting the effect of assigning variables in
 DTML, but it really isn't meant to have a direct way of declaring and
 assigning variables.  The way you're trying to use an object's properties
 will, I believe, cause problems in the case of simultaneous users, because
 it will act as a global variable.

Re: [Zope] Newbie question, help with navigation method

2000-12-06 Thread Dieter Maurer

Richard Blumberg writes:
   Navigation works when called directly,
  does not work when included in "index_html" 
  
  Navigation:
  dtml-in objectValues
 

  Is this a bug in Zope, or am I doing something wrong?
Not directly.

Almost surely, your "index_html" is a DTML document.
A DTML document defines the method "objectValues" and it
returns the empty list.
One *might* think of this as a bug or a feature.
(I tend to think of it as a bug).

In a DTML document (unlike a DTML method), the object
is pushed on top of the namespace stack.
Therefore, the "objectValues" in your navigation object
is the "objectValues" of the "index_html" and it returns
"[]".

If you would make your "index_html" a DTML method,
then "objectValues" would be the method of the
object for which the method is called for. This
means your folder. And it would work.

Thanks for the reply.
OK, I didn't phrase the question correctly.

I think it boils down to this:
If I have a string that represents a URL, can I define a method of my
product (in python, not in DTML) that redirects the browser to that
URL?

More details:


My product code is based on Boring (like most newbies I guess).
But manage_addBoring() does not do quite what I want. It returns
self.manage_main(self, REQUEST), so they end up at a long and ugly URL
that isn't where I want them to be anyway.

Example:
 the user is at:

http://localhost.localdomain:8080/Members/bobby

Bobby then clicks on a button I've provided that says "Add Test
Product". That sends him to the add form I've created. When Bobby
submits the request from this form, the product is added and he's sent
to

http://localhost.localdomain:8080/Members/bobby/manage_addProduct/MyProduct/manage_main
 

...because manage_addMyProduct returns self.manage_main
So I understand what's happening, but it's not what I want.
I don't want to send him there, I want to send him back to 

http://localhost.localdomain:8080/Members/bobby

So how can I do that from within the manage_addMyProduct method
definition?
The method gets a REQUEST argument, and I know that REQUEST['URL3'] is
what I want because if I return that string, it prints the URL I want.

I could do it by returning an HTML page with a redirect in the head
but that seems like a horribly ugly solution.


Looking through various Zope docs, I thought RESPONSE.redirect might
work, but  RESPONSE is not mentioned anywhere in Boring.py. Boring
only uses REQUEST.

Re: [Zope] newbie question: Redirect from Python?

2000-11-27 Thread Phil Harris

You need to be careful when redirecting from an external Python wotsit.

RESPONSE.redirect raises an exception which can make the transaction get
rolled back.

This seems not to happen when called from dtml but I've seen it happen from
an external Python wotsit.

Note:

My use of wotsit above in no way has a bearing on the new name for the
Python Methods/ZMethods/Script or whatever the hell they are called now. ;)

Aha, thanks. I didn't know that about the publisher.

Now I'm afraid I'm too stupid to see how to use RESPONSE.redirect
after reading the description in the Zope Book API appendix.

My method now looks like this:

def manage_addMyProduct(self, id, title='', REQUEST=None,
RESPONSE=None):
"""Add a MyProduct instance to the folder."""
self._setObject(id, MyProduct(id, title))
if REQUEST is not None:
whereto= REQUEST['URL3']
return RESPONSE.redirect(whereto, 0)


That just prints the URL as a string.
OK, so maybe I'm not supposed to use the return value?
So I try it like this:


def manage_addMyProduct(self, id, title='', REQUEST=None,
RESPONSE=None):
"""Add a MyProduct instance to the folder."""
self._setObject(id, MyProduct(id, title))
if REQUEST is not None:
whereto= REQUEST['URL3']
RESPONSE.redirect(whereto, 0)


Now when I submit the form, I can wait for a result forever and not
get anything.

How am I *really* supposed to do it?

Anyway, I'm now redirecting in manage_Add and it seems to work fine.

I tried the three methods you gave me. objectValues, "objectValues()"
and "objectValues('[File]')" and even "objectValues('[news999]')" but
empty everytime.

Thanks Philipp and Jim,

It worked! But... (there's always a but! :) I thought I was clever
when I thought about naming my news files news999, news998 etc,
thinking it would parse the directory and print the news sorted by
their names. So news998 would be printed before news999 etc. It
doesn't.

deleted questions because it's fixed :) /deleted

Now this too is fixed. I just discovered the "sort=" thingie.

One thing would sure be helpful, a Guide explaining all the subtags in
a tag. Like what can be used in a dtml-var or dtml-in and params
for each subtag. Because as someone mentioned, searching on zope is a
real hassle. It takes a long time, and the search is ORed. So lots of
unrelated docs are counted as a hit.

Thanks a lot to all the helpers.

Thanks! That's exactly what I was looking for.

I know that the DTML reference is there on Zope.org but it's a hassle
and well, I'll keep my other opinions for myself.

Anyway. Here's an idea. Shouldn't there be a list FAQ? If there is one
it should be sent when subscribing. Or it could be requested. I'm
pretty sure most of the questions I sent have already been sent 
answered more than once already and I know some that most other FAQs
use one. So, why not zope general list? It *is* possible, though
unlikely, that there is a list FAQ mentionned in the "Welcome to Zope
mailing list" email but if there is, my apologies.

Thanks.

 Hi,
 
 I have what I'm sure is a very simple question about Zope programming style:
 I want to count how many objects are contained in the current container
 object and then do something with that value, but I can't do the bit I need
 to do at the point of reading the count variable because I am in the wrong
 namespace.
 I can't begin a dtml-let because I would need to close dtml-if before
 dtml-let, which is not allowed.
 
 dtml-in objectValues
 dtml-if sequence-end
 dtml-var count-id  !-- this is the value I want to use --
 /dtml-if
 /dtml-in
 !-- this is the scope in which I want to do something with the value. --

dtml-call expr="REQUEST.set('countids', _.len(objectValues())"
dtml-in objectValues
dtml-if sequence-end
dtml-var countids
/dtml-if
/dtml-in
!-- do something with the value. --



 What is the "accepted" way of passing a value into a different scope? Do I
 have do a REQUEST.set or is there a tidier way?

dtml-let

 Also I think I read somewhere that you can use the object.subobject or
 object.property syntax but I never got that to work, what's the catch?

dtml-var expr="object.subobject"

note that this is a Python expression and the code between quotes has
Python behaviour.
 

 
 One last thing, I sent a couple of mails to the list about problems I had
 with manage_delObjects. I still haven't got it to work. Since the best way
 to learn Zope is by example, I wonder if anyone could direct me to a sample
 piece of code where a container of some sort deletes one of its children
 subobjects?
 


try (untested):
dtml-call "subobject.manage_delObjects([id1, id2, ..])"

Thanks Max, that is certainly useful in this case.

My query is really more general though, that was just an example, I need to
know what the generally accepted method is for transferring values through
the code (i.e between namespaces)

IMHO as far as Zope documentation goes, the thing that is really lacking is
a document introducing people to how to program in Zope, explaining the
overlaps between Python and Zope/DTML and explaining the different syntaxes
for calling variables, methods etc? There are a lot of references on
specific functions, methods etc but no general overview. Maybe the
forthcoming Zope book will address this better.

I am also still looking for example code using manage_delObjects.

Thanks,

Alex

I do believe that our ugly friend REQUEST.set() is the way to go here. I
cannot remember having seen any other way of doing it. I expect that better
days will be here with v.2.3 as we will get Python Methods, or whatever they
are called.

It looks like your addEntry.py file has some syntax mistakes in it

comparing it with what it should be and see if the problem goes away

Re: [Zope] Newbie question : ZopeTime permissions

2000-10-10 Thread Aaron Straup Cope

Yes, it was a misunderstanding regarding basic user permissions and the
Anonymous role on my part.

I did not want to allow the Anonymous role *any* permissions, and the
site I am working in is contained in a folder beneath the root Zope
folder. 

The problem was that I had disabled the "Access contents
information" privilege for the Anonymous user (whose permissions I forgot
are inherited by all other users) at the root level, thus preventing Joe
User from being able to access internals(?) like
ZopeTime even if [it] had permissions at a sub-directory level.

If I've got it wrong, I would be grateful if someone would correct
me. Otherwise, I hope that helps other newbies who find themselves in a
similar situation.

Sorry, I was wrong, at least partially!

The fact, that "ZopeTime" returns an unprotected DateTime object,
does of cause not mean that "ZopeTime" itself is unprotected.

After your message, I reexamined your problem:

 * "ZopeTime" is defined in "OFS.Application.Application",
   i.e. the top level application object.

 * "ZopeTime" apparently is not protected by an explicit
   permission (neither mentioned in an "__ac_permissions__"
   nor is there a "ZopeTime__roles__" attribute nor
   is there a new SecurityManager assertion about
   "ZopeTime".

   As I understand Zope 2.2 security, this should mean
   "ZopeTime" is inaccessible from DTML.
   
 * However, magically, "ZopeTime" is protected by "Access Contents
   Information". 

I can not tell you why.
Both is astonishable:
  * that it is accessible by DTML at all
  * why "Access Contents Information" is required.

Apparently, the Zope security still has some hidden magic.

That is one option.

However, images have properties of their own.
You can just define a new property "description" and give it

Look at the "PropertyManager" interface (- object reference

Re: [Zope] Newbie question: FORM processing in Zope.

2000-08-28 Thread J. Atwood

Easy and hard answer.

The easy answer is forget what you know about scripts/cgi and pulling in
form variables from some sort of CGI method (perl module). Since Zope is a
constant running process it does not require that you point to a script.

Hard Answer: The basics are that all you have to do is give the form element
a name (as you would in any form) and point the action of the form to
another DTML Method/Document. In that M/D all you have to do to get the
variable is call it with DTML-VAR variable_name

1) Create a form page with 'submit' with one text input box with a name of
'email_address'.

2) Point the action to a method called 'result' and create that

3) In the 'result' method include this code dtml-var email_address

4) Play around.

When you submit from one you should be taken to the second page and the
email_address should be there.

Now, for validation you can do all sorts of tricky things. I happen to like
to have the form point back to itself and have one method handle the entire
activity. You can validate things by asking for them, or trying to do
something else like put them into a database/email. If they are not there
you will get an error so you can use dtml-try. What makes Zope great is
that I can have the form and function in the same page (easier to
update/check).

Examples: (these are live and in production so please be kind)

http://fundraising.gotschool.com/tell_a_friend.html

http://market.gotschool.com/  (click on register for either school or
supplier and notice how the form is different for both).

Same thing done twice.

Re: [Zope] Newbie question: FORM processing in Zope.

2000-08-28 Thread Loren Stafford



A great resource for newbies is the collection of How-To's
http://www.zope.org/Documentation/How-To (or better yet:
http://www.zope.org/Members/AlexR/tips/howto_list where you can use browser
search to find what you need).

Search for "forms" and you will see, for example:

http://www.zope.org/Members/jules/smarterforms_html

In short, the methods of Zope objects are all "CGI scripts". For the
"action" of a form, you supply the url of a form-handling method of some
Zope object you have created. When that method runs, form fields are stored
in the dictionary (hash, to you) that implements the namespace for the
request. You access them as simple DTML variables: e.g.

dtml-var form_field_name

If you want to send the value of that form field on to another form, you do
it much the same as in Perl -- you code a hidden form field and assign it
the value dtml-var form_field_name.

Can anyone remind me why?

T0he problems it's caused, particularly with broswers caching basic auth
info, seem to be pretty nasty for newbies (and a few oldbies ;-)

You are working as superuser.
While this *did* work up to Zope 2.1.6, since Zope 2.2 the
security model was tightened.

You must (as superuser) create a user with manage privilege,
restart your browser and use that user to create objects.

Hi Mark,

  Zope Error
  Zope has encountered an error while publishing this resource.
  
  Error Type: SuperCannotOwn

The Content Manager Guide still describes the world
before Zope 2.2.

For some reason (that I do not understand), DC descided
that, starting with Zope 2.2.0, the SuperUser is no
longer Super but instead rather limited. He cannot own objects
and therefore, he cannot create objects.

What you need to do:

  As SuperUser go to "acl_users".
  Create a new user with a role of "Manager".
  Close your browser (all windows!).
  Recontact Zope (in a fresh browser!) as your newly created
  Manager.
  Use this manager, whenever your guide speaks of "SuperUser".

"_[xxx]" executes (calls) the retrieved object, if possible.
In your case, execution calls "RESPONSE.redirect".

You need "_.getitem(xxx)" instead of "_[xxx]".
This only retrieves and does not call the object.

Depends on how you want to do it, ie. server or client side. Consult the mailing list

Re: [Zope] Newbie question on page counters

"Richard P. Muller" wrote:
 I'm in the process of learning Zope hacking, and I'm having a really
 hard time getting a page counter to work. It isn't even that page
 counters are all that important to me, it's that I feel that if I can't
 even do something this simple, what hope do I have doing something
 really hard?

The ZODB is a _really_ bad place to store a page counter, especially on
a busy site.
Data.fs will grow each time your counter increments. This is because
it's a transactional daatbase with undo ability...

 Here's what I've done.
 (1) Under "Properties" I've created two properties (both ints)
 counter_starting_value, which I've set to 11 (arbitrarily)
 counter_value, which I've set to 0

Sounds good :-)

 dtml-if counter_value
 dtml-let counter_value = counter_value + 1
 /dtml-let
 dtml-else
 dtml-let counter_value = counter_starting_value
 /dtml-if
 dtml-var counter_value
 
 This didn't work. The error message reported that the syntax in the
 first (and probably the second, but I never got past the first) dtml-let
 command was wrong.

Whoops, just remember this:
DTML is not a programming language, it is designed for data presentation
and form processing. Or something like that ;-)

To do what you want, you probably want something like:

dtml-call
"manage_changeProperties(counter_value=getProperty(counter_value,counter_starting_value-1)+1)"

Which isn't pretty :S

Words simply cannot express my gratitude. Can you clue me in a bit more
on the functions you called. Looks like they are
manage_changeProperties(), getProperty(). I'm guessing these are both
Python functions. Where are they documented, so I can learn more?

You mentioned that (1) DTML is not a programming language, and that (2)
ZODB is a bad place to start on Zope programming. By these two points,
should I infer that learning how to write external methods in Python
*is* a good place?

Can you, or someone else on the list, give me a suitable homework
assignment for a first Zope programming project? I was toying with the
idea of writing a checkbook register in Zope, but I think it might be
beyond my capacities right now.

Thanks again,

You can img src="/images/logo.jpg" which will also work.

2000-05-28 Thread Stephan Richter


With dtml-call insertItem, Zope gives me following error message:

If the parameters are from another SQL statement, then the SQL method will 
not find them, since not the entire namespace is sent.

Try:
dtml-call "insertItem(param1=pvalue1, param2=pvalue2, param3=pvalue3, 
param4=pvalue4)"

pvalueX can be also a variable. If your variables are called paramX, then 
the following will work:

dtml-call "insertItem(param1=param1, param2=param2, param3=param3, 
param4=param4)"

That is typical Python syntax. So in case you want to know why and how that 
works, read a little in the Python documentation (which is btw excellent.)

Subject: [Zope] newbie question: case sensitive folder problem


 How can I make a folder on my site case - insensitive in regards to access
 from URLs.  If someone types http://mysite.com/bigfolder/ into their
 browser, I want it to take them to the Bigfolder, but right now, it
 produces a missing object error.  Any hints?  Sorry if this is a silly
 question - I'm just getting started here.

 I use zope with pcgi on Apache.

You can solve this using a DTML method called bigfolder:

dtml-call "RESPONSE.setBase(Bigfolder.absolute_url())"
dtml-with Bigfolder
  dtml-var index_html
/dtml-with


However, this won't help you if you want things to be totally
case-insensitive, like having "bIgFolDer" direct to "Bigfolder" for
example.

RE: [Zope] newbie question: case sensitive folder problem

2000-05-24 Thread Marcus Collins

You could try using Apache rewrite rules to convert all URL's to lower case,
and then use only lower case names for your folders, documents and methods.
As long as the case is consistent, one rewrite rule should cover everything.
