Re: [Zope] DTML Document size limit?
Hi Andrew, as discussed earlyer, there is no hard coded limit in the size of the files (ok, you might not go over 2GB per file) Althought its usually not nessecary to edit such big files.

Re: [Zope] Dynamically Picking which object to display
Hi Jason, Jason Lee wrote: I'm fairly new to Zope, so this may be a dumb question, and my vocabulary could be wrong, so please bear with me. I'm in the middle of building an e-commerce solution for my company, and we're evaluating Zope (and PHP and Servlets, but that's immaterial) as the platform on which to base this solution. That doesn't necessarily mean anything other than to give you context. One of the problems I'm facing right now is how to display a particular object based on a value. For example, let's say a user tries to access www.foo.com/MyAccount/CCInfo. If the user has authenticated, I need to show him the obviously sensitive data he has requested. If he is not authenticated, however, I need to give him a login screen which, for argument's sake, is in the DTML document Login in the root folder. How would I go about doing that? Am I making sense? Thanks... We have done it for an (closed to the public) e-commerce solution which could not be done with http-authentication (we have 2 user-names and one password for authentication for historical reasons) Se we needed a solution and found it as a simple solution with the standard header of all documents wich include some kind of session-management down the protected path. If the user is authenticated, the session management keeps track of it and provides useful data to all pages where it is included. If the session is timed out or a not authenticated user tries to access some pages, the session-management (a dtml-method) sends a redirect to the login-page.

Re: [Zope] YA newbie question
Hi Randy, ... I figured this would be easy to do with Zope. I created a subdirectory called "modules" and put some modules into that; for example, "leftbuttons" is a dtml method containing a table data block which contains the standard left menu button HTML. I figured I could whip up a page and at the appropriate place in that page, do a 'dtml-var "modules.leftbuttons"' and have that code inserted into the page. That was my thinking. "leftbuttons" views properly by itself. However, when I try that dtml-var statment above, the page displays raw HTML. try the following: either: dtml-var "modules.leftbuttons()" or: dtml-with modules dtml-var leftbuttons /dtml-with the reason for this is: anything inside "" is a python expression, meaning it is interpreted as if you typed it into an running python-interpreter (with the zope-context around, of course). So python calls the ojects __repr__() method here to display it. For string-like objects __repr__==__str__ (with single quotes arount them) For some zope objects "self-displaying" means showing their data as source. If you use dtml-var without the quotes, zope does do some magic with the __call__() method of the object. Calling a dtml-method renders its output rather then the source. This is what is done in the first variant. NB: often you have to provide the documents context to the method, so the above call is somthing like dtml-var "modules.leftbuttons(_,_.None)" (or such like - have to look again over some documentation or the list for this) HTH Tino Wildenhain ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Changing a Z object's __class__ dynamically
hi ... I don't know what exactly is going on. My conjectures are: (1) Digicool people have re-written Python's system function setattr(), so that when it is an Z Object, the __class__ cannot be changed. (2) Caching: when I change the class of a Z Object, somehow it does not reflected in the Z Object's memory-cached version. When I remember correcly, DC's setattr does not change attributes with leading underscore in a persistence way. These attributes are considered to be local.

Hm. I dont see the point here. First you can restrict the ability to Export/Import in the users role.

Hm. I dont see the point here. First you can restrict the ability to Export/Import in the users role.

May be I schould have a deeper look at the ownership-problem. Giving the importing user ownership over all objects (s)he imports as long it is not the superuser, schould do the trick. The problem is not so much ownership of the objects imported, but the type of objects that can be instanciated from a pickle (the export format wether XML or binary, consists of pickled classes). You can create _everything_ from a pickle, as long as there is a class definition for it; including a monitor client. I can open up a high port on your machine that'll let me connect to your Zope process in a python interpreter prompt. Then your server is my oister. Thats badly true, but importing of a whole bunch of objects is also often needed. IIRC does pickle only handle instance data but not class code. (although I see using of marshal in the import code which does in fact import code as oposite to pickle) Importing instance data schould not be a problem since it can only work if the user in question has access to the classes. This access is already handled by permissions. Moreover we could restrict importing via web to the superuser at all. Allowing imports from arbitrary paths will let me exploit security holes in other internet daemons on your machine to create a pickle file for import; preferably the /tmp directory as it is world writeable. Restricting imports to one directory allows you to be much more restrictive as to who can write there. You can set up restricted FTP access or even only allow scp (ssh encrypted file transfer) for trusted people to upload exports to the Zope import directory if you need to give others import rights. Uh, do you know any ssh-daemon for windows? ;-) Regards ;-) Tino ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Zope not starting after VaryTag install
Hi Didier,
so it looks like the vary Tag may be not compliant
to older ( 2.2.x) releases of Zope?
I have to check this. You should probably check if
you really need an ancient version of Zope ;-)
I'm really wondering how the tag can cause such a
behavior. Its almost an extract of the mime-tag
implementation which ships with zope.
Certanly you have a copy of your Data.fs before installation?
Good luck

as usual, if such things happen, "id" is a method.
it gets called by zope if you just use dtml-var on it.
So either use id() or better, look for title and
if not set (dont set a title on html_index then)
dont display it.

[Zope] Patch to avoid hypenation variables and more
Hi there, finally I want to release my patch for the in-tag. I hope it finds its way into the source-tree. I was sick writing such ugly constructs as _[_['sequence-item']] and so on, so I patched DT_In.py and DT_InSV.py (in lib/python/DocumentTemplate) to use sequence_item as well. All hypenation variables have now a second representation with underscores instead of hypenation. I hope, some time we can drop these hypenation variables. The second problem is if you put one in-tag into another. You have to use dtml-let oder REQUEST.set() with variables of the outher in-tag to be able to reference them in the inner loop. The code becomes very ugly this way. So my idea was to give the in-tag an optional argument, called "prefix" to prefix all the sequence-variables with a custom identifier. So you can write: dtml-in some_sequence prefix="outer_" dtml-in some_other_sequence dtml-var outer_sequence_item:dtml-var sequence_item /dtml-in the inner sequence /dtml-in the outer sequence What do you think about this? Attached are the patch files (g-zipped) They are a bit of size, but I choosed to send them as diff, as requested to avoid flames ;) (Althought the original files would be similar in size) If someone wants the whole files, feel free to write to me) Regards Tino DT_In.py.diff.gz DT_InSV.py.diff.gz

Any attribute coming from the sequence is untouched. This is also true for statistic variables and the magic "mapping" symbol.

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.

Well, ZSQL Methods always return result sets, never strings. The restult set is an object which works similar to a list with result objects, each result object having attributes which correspond to column names of your query. The result objects have a method dictionaries() which in fact return the data as regular list with dictionaries for the rows (easier to look at if you see their string representation) so what you probably want goes like this: result=container.getUserLevel(uname=user) if result: userlevel=result[0].userlevel else: userlevel=somedefault # or raise error or whatnot the if result: idiom handles the fact the query might not return any result. It is true however if you get at least one row. result[0] addresses the very first row of the result - which must exist in a non empty result set.

there's been some discussion about utf-8 vs. unicode strings on the

i have set my python default encoding to utf-8, i always send http
responses from zope as utf-8 (by setting the header like this:
tal:define=dummy python:request.RESPONSE.\
setHeader('Content-Type','text/html;; charset=utf-8')
)
maybe even better to wrap your template publishing in a
script - this would avoid such a moderate ugly code.
so if i'd like to use unicode strings in my zope applications, it's
still necessary to convert request variables to unicode by using
unicode(REQUEST.foo, 'utf-8'), right?
Yes, or you use :ustring and friends modifier in your forms.
See:
http://www.zope.org/Members/htrd/howto/unicode-zdg-changes
as far as i understodd, the conversion back to utf-8 is handled
automagically by zope (if the abovementioned header is set), also
correct?
Yes if you set the header in response and the body is of
type unicode. If your body is already encoded, you need
to make sure it matches whatever you set in the header.

} for r in context.your_zsqlmethod(arg1=argument1)] You can do a lot of preparation here. next you decide which template you want to output (can depend on request state or you use the same template for all states) return context.yourtemplate(data=somedata,value=value) Where you use tal:repeat=row options/data and tal:content=options/value So you can just use path expressions all over the place since you prepare all the data in your script. Complex data structures can be passed in (nested) dictionaries.

Re: [Zope] Still. Zope date datatype and TimeZone formatting problems.
Am Sonntag, den 22.05.2005, 13:01 -0500 schrieb Felipe Barousse Boue: Zopistas: I am experiencing the same problem you described by Mr. Hong Yuan in his post a few from last March. I have Zope 2.7.4, python 2.3.4 and PostgreSQL 8.0 and psycopg as DB adapter. All my dates stores in postgresql are WITHOUT timezone and my linux is set for the America/Mexico City time zone. All works fine at the OS and python level but not within Zope, it behaves as Mr. Hong Yuan describes in the post. I have noticed that Zope, when getting the data coming from postgresql (the date) always takes it to be at midnight in GMT time zone. While formatting the date for presentation, it doesn't take into account the OS TZ settings, it just assumes data (from postgresql) is at midnight in GMT and mangles it. Of course. I wonder why it should? Otoh, did you try to give the timezone you want when you select the data? If the TZ variable is set on the zope.conf file, it actually adds hours to the date (as like moving east), having first during the day having the date ok but a wrong time and, later on the day, the date goes wrong because of that timezone difference. I assume this setting is mainly for zope generated datetime objects, not something you read from a DB. If the TZ is not set in the zope.conf file it substracts hours from the date data from postgresql, effectively moving the date on day before, because it assumed midnight GMT. Doing further experiments I have noticed that when the data type passed to Zope is date (not datetime or timespamp, only date) then Zope misbehaves with the TZ, assuming it is on GMT and not taking into account the overall system (Operating system) time zone settings. Well, databases are often on a seperate host. How should zope guess in this case? If it would, I guess someone else would complaint ;) I have seen posts discussing this issue as far back as 2001. Has it been solved already ? Is it worth getting into the Zope code and trying to fix it and submit a patch ? Or its already deprecated ? or...? I believe it is still a huge bug the the Zope/Python date time handling routines, I am correct with this appreciation? Well, zopes DateTime implemenataion has some (serious) limits. But I dont think it should really be blamed for the above problems. Maybe some workarounds can be made in the psycopg driver. What btw. happens if you use mxdatetime instead of the zope builtin? Psycopg has this as configuration option.

In DTML I would like to do that :
I've this directory :

dir1 has property bar=1
dir2 has property bar=2

I would like a foo_html DTML Document file which display the property
bar. This file is place in dir1.
Exemple :
When I go to dir1/foo_html = I show 1
When I go to dir1/dir2/foo_html = I show 2
When I go to dir1/dir3/foo_html = I show 3
How can I do it ?
If foo_html is a DTML Method (Method, not Document!)
its just: dtml-var bar
(And god knows where the bar come from ;)
dtml-var expr=getProperty('bar')
could work too and would be more explicit.

meta charset does not count btw. CMF default should, but it really
depends on the real content-type header you send. Make sure its
the encoding you want there (setHeader() )
And its important to watch the encoding of the strings you work
with. Where does the dictionary come from?

If people had the discipline to not abuse the templating to do complicated logic. The major drawbacks of DTML are: - one namespace (with transparent layers) - confusing naming of tags, like dtml-var which really is dtml-print or something - and the extra tags for flow control, but probably the dtml fans can live with it. - peoples practice to use dtml-var foo even inside html-tags attributes, where dtml-foo; should be used. separated design as marketing says, for example see Plone - try to customize plone site to absolutelly different custom design - it is near impossible. Unfortunately Plone is still a bad example for ZPT. It is getting better but still it has a lot of code and definition in the templates.
