File input retuns what type?
by Jason Spisak 09 Sep '99

09 Sep '99

I am trying to upload a file into a property. I am using code that works to update the property: My form reads <input type="file" name="file" size="25" value=""> pretty standard fair.    But only when creating a ZClass instance I get this traceback: Error Type: AttributeError Error Value: 'string' object has no attribute 'read' Traceback (innermost last): File /Zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /Zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /Zope/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: RoleManager) File /Zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ResumeClass_add) File /Zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: ResumeClass_add) File /Zope/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: ResumeClass_add) File /Zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: ResumeClass_add) File /Zope/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: ResumeClass.createInObjectManager(_.str(PARENTS[-1].counter), REQUEST)) File /Zope/lib/python/DocumentTemplate/DT_Util.py, line 321, in eval (Object: REQUEST['file'].read()) File <string>, line 0, in ? File /Zope/lib/python/DocumentTemplate/DT_Util.py, line 125, in careful_getattr AttributeError: (see above) Doesn't the <input type="file"> return a file object in zope? The above code works to update the property, why not to create it? Any ideas? Jason Spisak webmaster(a)mtear.com

It apparently isn't calling __call__ at all. It doesn't call *your* __call__ or it raises an exception? It might be calling a __call__ method defined in a Base class that supercedes the one you define. -Michel

Zope.org beta topic suggestions
by Mike Pelletier 08 Sep '99

08 Sep '99

Hi. I am in the process of enriching Zope.org Beta's Z Classes to provide more information about their content. For instance, if you take a look at HowTo's new Properties view, you'll notice two new options-- 'Difficulty' and 'Topic'[1]. 'Difficulty' can be one of 'Beginner', 'Intermediate' or 'Advanced'. 'Topic' contains any number of pre-defined How-To topics. I am interested in getting feedback from users about how they would like to see the Z Classes enriched. Each property I add to the Z Classes will offer a list of options as opposed to free text. What I want to know is, what options should be available for each Z Class's topics, and what additional properties, if any, should be added? Take a look at HowTo for an example, and don't be shy. Mike. [1] Please don't confuse my use of 'topic' in this context with Amos's in yesterday's topic proposal. They are different things. -- Mike Pelletier email: mike(a)digicool.com Mild mannered software developer icq: 7127228 by day, super villain by night. phone: 519-884-2434

Permission to Add ZClasses
by Jason Spisak 08 Sep '99

08 Sep '99

Gang, I have a ZClass called foo, and I have a user with a role that can "Add foos". The user can acces the fooClass_Addform, but not the fooClass_factory. Is there anything else that I have to lever 'on' in order to let people addZClass instances? The Add Permission was created default by ZClasses. The Manager Role can add them, but the other role, even with every permission checked inthe root folder and everything else aqcuiring, cannot. Jason Spisak webmaster(a)mtear.com

I recognize that code :) That external method specifically copies all objects in a Folder (fobj) to a destination Folder (tobj). I wrote it for a very specific purpose. You may just want to use manage_clone. (You can look at all of the available copy/paste functions in Zope/lib/python/OFS/CopySupport.py). >From DTML, you could probably do something like: <dtml-call "REQUEST.set('source', docID)"> <dtml-with destinationFolder> <dtml-call "manage_clone(source, 'newID', REQUEST)"> </dtml-with> Replace "docID" with your document's ID, destinationFolder with your destinationFolder and make sure that you're able to get to both of those objects (via acquisition or whatever). If you're still havnig trouble, it would help to know the specific context in which you're calling that external method or manage_clone...

Calling a DTML Method from Python
by Martijn Faassen 08 Sep '99

08 Sep '99

Hi there, I'm attempting to write a product that calls a DTML method during its processing. The product keeps a table of DTML method objects and has a method that determines what DTML method to call, and then calls it. I'm not sure _how_ I should call a DTML method object, though. Example: class Foo: def __init__(self): self.map = {} def setMap(self, keyword, method): self.map[keyword] = method def render(self, keyword): return self.map[keyword]() # ?? What arguments are needed? Then, from DTML: <dtml-call "foo.setMap('hey', somemethod)"> ... <dtml-var "foo.render('hey')"> Is this possible at all? I assume render() actually needs extra arguments to make this work, but which? The DTML Method source defines this: def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw): What does the client argument stand for? Anything else I should watch out for? I keep running into mysteries like this continuously, it seems... Regards, Martijn

Catalog search cannot sort on a FieldIndex?
by Martijn Pieters 08 Sep '99

08 Sep '99

Hello all, and especially Michel =) Why is it I query the ZCatalog, and have the results sorted on a FieldIndex? Something like: res=apply(cat.searchResults, (), {'sort-on': 'aFieldIndex'}) gives me a AttributeError: items on line 411 of Catalog.py. Maybe I am trying something very stupid here. I have a bunch of objects catalogued with a FieldIndex on a DateTime property. If call searchResults without arguments, it all works beautifully, and the result objects sport my DateTime property. But I want to retrieve these objects sorted on the DateTime property. Note that I want the results sorted by the Catalog, I am not using this in any DTML, so I cannot rely on the in tag's sort attribute. I also wanted to use the more efficient sort results of the Catalog, and the advantages of the LazyCat object.. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
