Re: [Zope3-Users] Indexing PDF files
Hi, On Wed, May 10, 2006 at 03:29:34PM -0500, Sreeram Raghav wrote: [snip] Initially the only files being indexed were ZPT pages, but after writing the adapter even text files were being indexed. However the problem is that when I try to add a PDF of Word documents, the files are not being indexed and showing an error that cannot decode files. This adapter was just a demonstration on how to index a content object containing a text field. It assumes that context.data contains just a plain string. To index pdf files, you'll have to somehow convert the pdf data to plain text: from ModuleYouHaveToWrite import MagicPdfToText class SearchableTextAdapter(object): [...] def getSearchableText(self): text=MagicPdfToText(context.pdfdata) return (text,) I don't know, if there's a pure python solution for extraction text from pdf files. But you might consider calling an external program like 'pdftotxt' to do the job. However, it's your adapters responsibility to act as define by the interface and 'ISearchableText' says, the adapter must provide plain indexable text.

[Zope3-Users] Problems with ZDC upgrading to Zope 3.3.0b1
I've encountered a problem running zope 3.3.0 beta1 against a zodb created 3.2. As a consequence of moving zope.app.dublincore to zope.dublincore, it seems DC annotations on old instances break, i.e. persistent broken zope.app.dublincore.annotatableadapter.ZDCAnnotationData instance '\x00\x00\x00\x00\x00\x00\x00%' In the meantime I can work around this by dummy'ing zope.app.dublincore. Is there a migration operation I need to run? Clicking evolve: http://localhost:8080/++etc++process/@@generations.html doesn't seem to do the trick. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Skinning in Zope 3.3
Hi, I try to understand how to customize the look feel of my page using the new skin/layer implementation of version 3.3. I followed the example on http://www.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/SimplifySkinning but still don't understand on how to change the layout of my page.

RE: [Zope3-Users] Skinning in Zope 3.3
Both of the Zope 3 developer's books explain this quite well. I think Phillip's has the shortest example. Skins are one of the few Zope 3 concepts I was able to implement quickly. All sources will assume that you understand TAL, and METAL. You can download the source from either book either of the Zope 3 SVN or the worldcookery site. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Achim Domma Sent: Thursday, May 11, 2006 4:04 AM To: zope3-users@zope.org Subject: [Zope3-Users] Skinning in Zope 3.3 Hi, I try to understand how to customize the look feel of my page using the new skin/layer implementation of version 3.3.

[Zope3-Users] ComponentLookupError
hi there here's a smaller, hopefully more clearer example of a problem I have been stuck on. I should probably also lead off by saying that I think what I am asking is basically this question. http://www.mail-archive.com/zope3-users@zope.org/msg00052.html However I have read objectwidget.txt( http://svn.zope.org/Zope3/trunk/ src/zope/app/form/browser/objectwidget.txt ) several times and I don't see where a custom widget gets created. I also suspect that because the object I need to create a custom widget for has more than just one field I have to do something different. If there's a short fix for the problem that would be great, otherwise a little explanation to point me in the right direction would be greatly appreciated too. thanks. -jachin Here's the error I'm getting any my code: 2006-05-11T11:56:47 ERROR SiteError http://localhost:8080/@@+/ action.html Traceback (most recent call last): File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 138, in publish result = publication.callObject(request, object) File /usr/local/Zope-3.2.1/lib/python/zope/app/publication/ zopepublication.py, line 161, in callObject return mapply(ob, request.getPositionalArguments(), request) File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 113, in mapply return debug_call(object, args) File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 119, in debug_call return object(*args) File /usr/local/Zope-3.2.1/lib/python/zope/app/container/browser/ adding.py, line 128, in action name=view_name) is not None: File /usr/local/Zope-3.2.1/lib/python/zope/component/ __init__.py, line 165, in queryMultiAdapter return sitemanager.queryMultiAdapter(objects, interface, name, default) File /usr/local/Zope-3.2.1/lib/python/zope/component/site.py, line 75, in queryMultiAdapter default) File /usr/local/Zope-3.2.1/lib/python/zope/interface/adapter.py, line 475, in queryMultiAdapter return factory(*objects) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/browser/ editview.py, line 64, in __init__ self._setUpWidgets() File /usr/local/Zope-3.2.1/lib/python/zope/app/form/browser/ add.py, line 49, in _setUpWidgets setUpWidgets(self, self.schema, IInputWidget, names=self.fieldNames) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 153, in setUpWidgets context=context) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 97, in setUpWidget widget = _createWidget(context, field, viewType, view.request) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 65, in _createWidget return zapi.getMultiAdapter((field, request), viewType) File /usr/local/Zope-3.2.1/lib/python/zope/component/ __init__.py, line 154, in getMultiAdapter raise ComponentLookupError(objects, interface, name) ComponentLookupError: ((zope.schema._field.Object object at 0x4282b70, zope.publisher.browser.BrowserRequest instance URL=http://localhost:8080/@@+/action.html), InterfaceClass zope.app.form.interfaces.IInputWidget, u'') 127.0.0.1 - - [11/May/2006:11:56:47 -0500] GET /@@+/action.html? type_name=AddPerson.html HTTP/1.1 500 84 http://localhost:8080/ @@contents.html Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en- US; rv:1.8.0.3) Gecko/20060427 Camino/1.0.1 interfaces.py from zope.interface import Interface import zope.schema class IStreetAddress(Interface): A vine street address street = zope.schema.Text ( title=uStreet 1, description=uThe street address, required = False ) city = zope.schema.TextLine ( title=uCity, description=uThe city., required = False ) state = zope.schema.TextLine ( title=uState, description=uThe state., required = False ) zipcode = zope.schema.TextLine ( title=uZip Code, description=uThe zip code, required = False, min_length = 5 ) class IPerson(Interface): firstName = zope.schema.TextLine ( title=uFirst Name, description=uThe person's first name, required=False ) lastName = zope.schema.TextLine ( title=uLast Name, description=uThe person's last name, required=False ) address = zope.schema.Object ( title=uAddress, description=uThe person's adderess, required=False, schema = IStreetAddress ) person.py from persistent import Persistent from zope.interface import implements from
