[Zope] ZSQL database connection (ZPoPy) not giving expected results
Ok, here's the situation. I create a folderish object. I insert some info into the postgresql database related to this folderish object. I create a ZPopy database connection within this folderish object. All of this is done through a python method. If I do a query using this new database connection, select for rows I just inserted. The query comes back with no results. I can do this query using another ZSQL DB connection, and on the command line, it works fine. Caching is off for the query. Eventually, after 30 seconds to 4 minutes, all queries seem to work fine. This behavior is inconsistent, sometimes the queries work after no wait at all. Any ideas? ___ 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 )

In this case, at least one of the items is not callable ( like another folder). If you did something like this: You would see the results of 'viewing' or calling every DTML Method in folder.

Re: [Zope] Creating Object
You're logged into the zope management interface as superuser. To change this, create a user in the root acl_users folder, giving it a username and password, and the manager and owner roles. Now restart your browser, go to the management interface, and log in as the user you just created. You should be able to create objects.

Re: [Zope] Dynamically render DTML?
Thanks too all who replied, I may have simplified my problem a little too much before posting it. The heart of it is that I'd like to have the Zope evaluate an arbitrary string as if it were a DTMLMethod For those interested, here is what I ended up doing... -- pyfile.py from OFS.DTMLMethod import DTMLMethod class myclass: """ a callable object: This is acting as a base class for a ZClass """ def __call__(self,REQUEST): """a callable object - I pass in REQUEST because my dtml-vary seems to require it """ # create your dtml string - note: the idea is, this doesn't have to be a static string... text= '\ ENGLIS TITLE\ THIS IS ENGLISH CONTENT\ \ THSI IS FRENCH CONTENT\ \ Spanish title\ This is spanish text\ ' met h=DTMLMethod() # populate the DTMLMethod meth.manage_edit( text,'THIS IS THE TITLE') #the DTMLMethod goes out of scope here, so it's never persistent ( I hope ). return meth(REQUEST) -- I call this from from zope as follows... - m1 is an instance of a ZClass that has myclass as a base class. this calls myclass.__call__(self,REQUEST) - This solution worked for me. It would still be nice if I didn't have to pass REQUEST explicitly. I could have derived myclass (or the ZClass) from DTMLMethod, but I didn't need the DTMLMethod itself to be persistent. Also, I'm not sure how to intercept __call__ and pas it on to the DTMLMethod. It's a little ugly, but it works. It would be nice to be able to just say in zope and have it render.

[Zope] Dynamically render DTML?
Is it possible to return dtml from python, and have it rendered correctly on the page? for example, the python might look like this... def get_header(somevar=1): if somevar==1: return '' else: return '' The dtml document in the zodb might look like this... Body text When this gets rendered, it's as if the dtml document had in place of the get_header call. I understand how to call external methods from dtml, etc. I just want to know if it's possible to get the string returned rendered as dtml.

[Zope] Re: Fwd: Re: [Zope] R: [Zope] Invalid Header (0) error
We've had the same problem, Michael Pelletier addressed this question in a previous post, Check out: http://www.egroups.com/message/zope/29589?&start=29498 To summarize, 'Zope doesn't like it if there is no html tags before the DTML begins.' To fix our problem, we simply make sure that a html comment as the first line in every page, through the standard_html_header.
