POSting from a python script.
by Alec Munro 06 Dec '02

06 Dec '02

Hi all, Is it possible to post data to a site from a python script? Basically I want have the user fill out a form, have that form's action be a python script, and then have the python script submit a post request to another site, and then return a page on my site to the user. I'm sure if this can be done it's fairly trivial, but I cannot think of how to do it. Also, I want to be able to recieve the response to the posted data. Thanks, Alec Munro

ZopeTop, xul, etc.
by Philippe Jadin 06 Dec '02

06 Dec '02

Hi, It seems there is currently work done on the future UI for zope3. I have some questions / comments on this (I hope it's the right list...) - Isn't it strange to use html to create a modular user interface? As I see it, html is not an UI definition language. - is there currently active projects to build a fat client interface for zope using xul or other technology? If html is not the right tool for the job, and if xul is really as good as it seems : - zope should use an intermediate layer between the core logic / datastructures and the UI. This layer could be something like xul - xul is xml, and as such could be "converted" to xhtml. The conversion would reduce a lot the usability (you cannot do everything xul does with html), but at least there would be a single source of UI definition and multiple implementations (simple html, "flashy" dhtml, pure mozilla xul, etc...). - xul can be used directely in mozilla, providing a very powerfull client-side interface. I think it can be seen as a rapid interface developement tool. In short, zope core -> "html ui" is not too good zope core -> "something" -> html would be more modular. the "something" could be xul... or wathever, the point is "there must be something" :) What do you think? Philippe Jadin ps : is it possible to contact the people currently working at the infrae sprint (irc?)?

Re: Bug or Feature (dtml-in)?

Sorry, even my solution didn't work, because I confused mySequence_start with mySequence-start. So, the problem remains, that unauthorized people have the sequence-start attribute set in every run of the loop, whilst authorized people get it the expected way. Any suggestions?

Bug or Feature (dtml-in)?
by Lars Heber 06 Dec '02

06 Dec '02

Hello list, I just found s. th. really strange with the following code:: <dtml-in "objectValues(['Folder'])" skip_unauthorized="1" sort="index"> <dtml-if sequence-start><ul></dtml-if> <dtml-if "id != 'templates' and _.getitem(id).objectValues(['Datenblatt'])"> <li><a style="font-size:16pt" href="&dtml-absolute_url;/doSomething"><dtml-var title_or_id></a></li> </dtml-if> <dtml-if sequence-end></ul></dtml-if> </dtml-in> Worked fine, except that if one wasn't authorized to access a folder, the property sequence-start was always set - resulting in repeated <ul>s. But by using the prefix attribute it worked: <dtml-in "objectValues(['Folder'])" skip_unauthorized="1" sort="index" prefix="mySequence"> <dtml-if mySequence-start><ul></dtml-if> <dtml-if "id != 'templates' and _.getitem(id).objectValues(['Datenblatt'])"> <li><a style="font-size:16pt" href="&dtml-absolute_url;/uebersichtArtikelgruppe"><dtml-var title_or_id></a><br /><br /></li> </dtml-if> <dtml-if mySequence-end></ul></dtml-if> </dtml-in> I think something is going wrong here with the namespaces, or did I miss something.

Zope-2.6.0-solaris dumps core
by Johan Lübcke 06 Dec '02

06 Dec '02

Hi I have a few helper scripts to do some ZODB modifications from the outside, using "import Zope; a=Zope.app()" but after upgrading to 2.6.0 they stopped working. I can reproduce the core dump with: --- 8< --- 8< --- bash-2.03# /usr/local/bin/tar xfz ~peter/Zope-2.6.0-solaris-2.8-sparc.tgz bash-2.03# cd Zope-2.6.0-solaris-2.8-sparc/ bash-2.03# ./install ------------------------------------------------------------------------------ Compiling python modules ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ creating default inituser file Note: The initial user name and password are 'admin' and 'Te7iq1Ud'. You can change the name and password through the web interface or using the 'zpasswd.py' script. chmod 0600 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/inituser chmod 0711 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/var ------------------------------------------------------------------------------ setting dir permissions ------------------------------------------------------------------------------ creating default database chmod 0600 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/var/Data.fs ------------------------------------------------------------------------------ Writing the pcgi resource file (ie cgi script), /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/Zope.cgi chmod 0755 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/Zope.cgi ------------------------------------------------------------------------------ Creating start script, start chmod 0711 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/start ------------------------------------------------------------------------------ Creating stop script, stop chmod 0711 /tmp/junk/Zope-2.6.0-solaris-2.8-sparc/stop ------------------------------------------------------------------------------ Done! bash-2.03# export PYTHONPATH=lib/python bash-2.03# bin/python -i -c "import Zope" >>> a=Zope.app() >>> ^D bash-2.03# bin/python -i -c "import Zope; a=Zope.app()" ZODB/cPickleCache.c:445: failed assertion `key != Py_None' Abort (core dumped) bash-2.03# --- 8< --- 8< --- The confusing part is that it works if I do it manualy from the python prompt, but fail to execute if I do it in a script...

Class property in object creation form
by Thierry Florac 06 Dec '02

06 Dec '02

Hi, I'm currently building several Zope products working quite well but with which I have a problem : how can I define class properties (most often defined as lists actually) and use them in my creation forms written in DTML. For example, I've tried to use: in file MyProduct.py : class MyProduct(...): MyProductProperty = [ 'item1', 'item2', 'item3' ] def getMyProductProperty(self): return MyProduct.MyProductProperty in file __init__.py : import MyProduct ... def initialize(context): context.registerClass (MyProduct.MyProduct,...) ... methods={'myproduct_property':MyProduct.MyProduct.getMyProductProperty} and finally in my DTML file : <dtml-in myproduct_property> ... </dtml-in> But when I call my creation script from the ZMI, I get an error: Traceback (innermost last): * Module ZPublisher.Publish, line 150, in publish_module * Module ZPublisher.Publish, line 114, in publish * Module Zope, line 171, in zpublisher_exception_hook * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 252, in __call__ * Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec * Module App.special_dtml, line 174, in _exec * Module DocumentTemplate.DT_In, line 628, in renderwob * Module DocumentTemplate.DT_Util, line 201, in eval __traceback_info__: myproduct_property * Module <string>, line 0, in ? * Module None, line 58, in getMyProductProperty ImportError: No module named MyProduct I forgot to tell you that I use Zope-2.6.0 with Python-2.1.3, and that I didn't found any good example or documentation about this point anywhere...

Newbie Qu: user login in private folders
by Matthew 06 Dec '02

06 Dec '02

Hi all, Having a really hard time here. I'm trying to create separate folders for each of my clients, and I don't want anyone else but them to access anything in the folder. I've read many ways of settings the permissions to make the folder private, and I think I have the hang of that. The problem: I create a user in their private folder, but they can't log in. The only allowable log-ins seem to come from the top CMF folder. I even tried creating a test without any restrictions just to log in- but still only users from the top CMF folder can log in. Can someone please let me know what I'm doing wrong, or point me in the right direction. I know everyones busy, but I really can't figure out what's happening. Many thanks. Matthew.

security and domain
by Nicolas LAURANCE 06 Dec '02

06 Dec '02

hello zopers, Here is my situation : I have a zope hosted behind apache and virtual monster When i need the ip address of a visitor I use HTTP_X_FORWARDED_FOR I want some users to log only from a specific IP for example : 100.100.50.25 If I set 'domain' in the acl_user fiels to that IP, it doesn't work, I guess the domain it returns is the domain of the Apache or proxy server. Is there a workaround for the domain to be checked against the HHTP_X_FORWARDED instead of the IP_ADDRESS ??? Any help or pointers is welcome...

Re: Detect ZOPE version inside a product
by Josef Meile 06 Dec '02

06 Dec '02

Hi, > How could I detect the running Zope version inside a product? There is a varible in the REQUEST object: SERVER_SOFTWARE. In my case it is: "Zope/(Zope 2.5.1 (binary release, python 2.1, linux2-x86), python 2.1.3, linux2) ZServer/1.1b1" You have to do some strings operations in order to get it. Regards, Josef.

confused about optional args to ZSQL methods
by Skip Montanaro 05 Dec '02

05 Dec '02

I think I may have encountered this problem before and asked about it. If so, any solutions offered at that time escape me now. I have this ZSQL method (get_workorder): <params>id worker_id end_date</params> select * from work_order <dtml-sqlgroup where> <dtml-sqltest name=id op=eq type=int optional> <dtml-and> <dtml-sqltest name=worker_id op=eq type=int optional> <dtml-and> <dtml-sqltest name=end_date op=ge type=string optional> </dtml-sqlgroup> ; In a Python script I want to call it like so: workorders = context.sql.get_workorder(worker_id=worker_id, end_date='2003-04-23') that is, omit the presumably optional id parameter. However, when the Python script is run, the ZSQL method complains "Invalid integer value for id". I also tried these forms: workorders = context.sql.get_workorder(**{'worker_id': worker_id, 'end_date': '2003-04-23'}) workorders = context.sql.get_workorder(**{'id': None, 'worker_id': worker_id, 'end_date': '2003-04-23'}) workorders = context.sql.get_workorder(id=None, worker_id=worker_id, end_date='2003-04-23') without success. The first form gave the same error as above. The other two gave "object can't be converted to int". How do I arrange things so I can call get_workorder without passing the id parameter?
