Using classes in python extensions...
by Robert McPeak 22 Jul '03

22 Jul '03

I'm sure that this is a silly question, but I'm going ask it anyways... ;) How do I instantiate/use classes inside of a python extension from zope? Thanks. Rob McPeak Python programmer reduce(lambda x,y:x+y,map(lambda x:chr(ord(x)^42),tuple('zS^BED\nX_FOY\x0b')),'')

Odd behaviour with lexicons and ZCTextIndex
by Paavo Parkkinen 22 Jul '03

22 Jul '03

We have a site with the following structure: / `- foo |- lexicon `- bar (foo and bar are ZClasses) When I add the 'bar' under 'foo', and in 'bar's constructor, add a catalog to bar and a ZCTextIndex to the catalog with an external method[1], in 2.6.0 it works just fine, but with 2.6.1 I get the following error: Error Type: LookupError Error Value: Lexicon "lexicon" not found The end of the traceback looks like this: * Module Products.ZCatalog.ZCatalog, line 897, in addIndex * Module Products.ZCTextIndex.ZCTextIndex, line 78, in __init__ LookupError: Lexicon "lexicon" not found [1] the external method we use for adding ZCTextIndexes: def addZCTextIndex(context, id, field=''): extra = Extra() extra.index_type = 'Okapi BM25 Rank' extra.lexicon_id = 'lexicon' if field: extra.doc_attr = field if id: context.addIndex(id, 'ZCTextIndex', extra) -- paavo.

Generic add page template fails
by Josef Meile 22 Jul '03

22 Jul '03

Hi, I'm trying to do a generic add page template where I don't have to write the class name. The name will be taken from an attribute of the template object. If you see the file OFS/Image.py, you will see something like this: manage_addImageForm=DTMLFile('dtml/imageAdd',globals(),Kind='Image',kind='im age') The attribute Kind is called from OFS/dtml/imageAdd.dtml like this: <dtml-var "manage_form_title(this(), _,form_title='Add %s' % Kind,help_product='OFSP',help_topic='File_Add.stx')"> And if you continue scrolling this file, you'll see something much better: <form action="manage_add<dtml-var Kind>" method="post"enctype="multipart/form-data"> I'm trying something similar with ZPT, but it fails: in my class I do: manage_addBoringForm=PageTemplateFile('ZPT/addBoring',globals(),Kind='Boring ',kind='boring') manage_addBoringForm._owner=None and in the ZPT File I have tried: <h1 tal:define="Kind xxx/Kind;pageTitle python:here.manage_form_title(here, request,form_title='Add %s' % Kind)" tal:replace="structure pageTitle">Add myClass </h1> Where xxx is 'here', or 'template', or 'request' In all of the cases it returns: Traceback (innermost last): 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 Products.PageTemplates.PageTemplateFile, line 96, in _exec Module Products.PageTemplates.PageTemplate, line 95, in pt_render - <PageTemplateFile at /pythonTest/> Module TAL.TALInterpreter, line 200, in __call__ Module TAL.TALInterpreter, line 244, in interpret Module TAL.TALInterpreter, line 473, in do_setLocal_tal Module Products.PageTemplates.TALES, line 220, in evaluate - URL: addBoring - Line 2, Column 0 - Expression: standard:'xxx/Kind' - Names: {'container': <__FactoryDispatcher__ instance at 01C46FF0>, 'default': <Products.PageTemplates.TALES.Default instance at 00EDBF9C>, 'xxx': <__FactoryDispatcher__ instance at 01C46FF0>, 'loop': <SafeMapping instance at 01D9C6A8>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 00EE554C>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at 01D9C6A8>, 'request': <HTTPRequest, URL=http://localhost:8080/pythonTest/manage_addProduct/Boring/addBoring>, 'root': <Application instance at 01B2A560>, 'template': <PageTemplateFile at /pythonTest/>, 'traverse_subpath': [], 'user': admin} Module Products.PageTemplates.Expressions, line 206, in __call__ Module Products.PageTemplates.Expressions, line 194, in _eval Module Products.PageTemplates.Expressions, line 150, in _eval - __traceback_info__: xxx Module Products.PageTemplates.Expressions, line 360, in restrictedTraverse - __traceback_info__: {'path': ['Kind'], 'TraversalRequestNameStack': []} AttributeError: Kind It seems like this attribute isn't stored on my Template. Does somebody know how to do something similar with ZPT? Thanks in advanced, Josef

"Init Ambigous name ..." for PageTemplateFile
by peter＠mail.grenna.net 22 Jul '03

22 Jul '03

I get messages like this when I use this code (pseudo):: MyClass.__dict__['page.html'] = MyClass.page_html 2003-07-21T13:47:24 PROBLEM(100) Init Ambiguous name for method of Products.QDProduct.QDSP.QDSP: "changesettings_html" != "changesettings.html" With the DTMLFile module, when this happens I use _setName() and the message goes away. _setName() does not work for PageTemplateFile instances. What should I use? I have searched the mailinglist but to no avail.

Failed to reset inituser
by Wouter Vanden Hove 22 Jul '03

22 Jul '03

Silly me, I lost my password to the zope-management interface. I try to set a new one via the shell, but I receive following error: [root@*** zope]# python zpasswd.py inituser Username: admin Password: *** Verify password: *** Please choose a format from: SHA - SHA-1 hashed password (default) CRYPT - UNIX-style crypt password CLEARTEXT - no protection Encoding: SHA Traceback (innermost last): File "zpasswd.py", line 200, in ? if __name__=='__main__': main(sys.argv) File "zpasswd.py", line 184, in main if encoding.upper() in ['SHA', 'CRYPT', 'CLEARTEXT']: AttributeError: 'string' object has no attribute 'upper' Anyone know a solution? Since execution halts, the new inituser-account is not active, so I can't login. Wouter Vanden Hove

Perhaps the python that comes with your linux isn't the same one of the one that you use with zope. Some old python versions doesn't support things like: myString.upper() So, you had better try: PathToMyZope/bin/python zpasswd.py inituser or if you compiled python from source, you should use this path.

OK, I've solved it by using another way (details are below) > I'm trying to do a generic add page template where I don't > have to write the class name.

My idea, as you see, is to write a macro that I can use from another Products, which I will migrate from ZClasses to python based products. Greetings, Josef

Using DB Connection in Zope Product?
by Chris Bruce 22 Jul '03

22 Jul '03

Is there a way to develop a zope product (filesystem based) that can use a Zope DB Connection object that exists in the ZODB? I want to create a product and allow the user to specify the database connection to use. If so, how do you reference an existing object in your product code. Also, can you recommend any good product development tutorials? Thanks in advance. Chris
