Is there a way to get the current object's class name? <dtml-var "this.__class__.__name__"> doesn't work.

EventLogManager1.0
by Chris McDonough 16 Aug '00

Folks, Available at http://www.zope.org/Members/mcdonc/Products/EventLogManager is my attempt to write a somewhat smarter logging facility for Zope. It supports complex rules processing and configurable targets (syslog and file). It's been tested under Linux only but should work on Win32 and other UNIX derivatives. Give it a roll.

I think, it is a bug in acquisition
by cuiod-tec Jens Gelhaar 16 Aug '00

16 Aug '00

Maybe I have found a situation, where images are not working or rather acquisition. For example, you create 2 documents and one image doc1 (DTML Document) contents: "document 1 <dtml-var doc2> doc2 (DTML Document) contents: "document 2 <dtml-var image> image (Image) contents: image When you put everything in one folder and try to render doc1, everything works fine. You get your image at the end. But if you put doc1 in a folder below like doc2 image subfolder doc1 you get the appended error. When you remove the image call from doc2 everything works again. I checked this with JPicture - the same. Beside, today I posted another mail with "[Zope] __call__ error message - I gave up". In this situation I thought my coding was wrong because I wanted to list all documents with <dtml-in "objectItems('DTML Document')"> <dtml-var sequence-item> </dtml-in> Any Help?

Re: [Zope] Reloading file objects?

I tried to put that in the document I call the > pdf-file from but that didnt work. The following DTML method (view) adds a header to a file/image: <dtml-call "RESPONSE.setHeader('Expires',_.str(ZopeTime()-1))" ><dtml-var "PARENTS[0].index_html(REQUEST,RESPONSE)"> The "><" at the start of the second line may be necessary to prevent spurious whitespace before the image. Almost surely (not tested), you can use alternatively Expires: <dtml-var "_.str(ZopeTime()-1)"> <dtml-var "PARENTS[0].index_html(REQUEST,RESPONSE)"> This uses Zope's CGI compatibility: the body of a response generated by a DTML method (or document) may be preceeded by a sequence of HTTP headers separated from the body by a single blank line. You would use this method in URLs in the following way: <URL to your image>/view Dieter

Creating properties with a product.
by jesse 16 Aug '00

16 Aug '00

Hello, I recently created a product which adds a folder, with multiple dtmldocuments inside of it, effectivly creating a site immedatly. However, even though I can add folders and documents easiliy, I can't seem to create properties! It keeps giving me the Attribute error: aq_base. Here is the code for the function that does the work: def manage_addMemberSite(self, id, title='',REQUEST=None): """Add a MemberSite folder.""" try: user=REQUEST['AUTHENTICATED_USER'] except: user=None folder = MemberSite(id, title) # _setObject must be the Zope hook that actually stores this instance in # the ZODB self._setObject(id, folder) folder.manage_addFolder(id='Images', title='') folder.manage_addDTMLDocument(id='index_html', title='', file=index_body) folder.manage_addDTMLDocument(id='navbar', title='', file=navbar_html) folder.manage_addDTMLDocument(id='content', title='enter page content here', file=default_dd_html) folder.manage_addProperty(id='nav_color', value='#483D8B', type='string') folder.manage_addProperty(id='content_color', value='#F0E68C', type='string') folder.manage_addProperty(id='background_color', value='#FFFFFF', type='string') if REQUEST: return self.manage_main(self, REQUEST, update_menu=1) The folder.manage_addProperty(id etc etc) does not work. I have been looking all over, have looked to where the error seems to stem from, (the valid_property_id function in the PropertyManager.py) but I can't seem to find out whats wrong. Does anyone have any ideas? Please respond ASAP.

How can I find memory leaks in External Methods?
by Tony McDonald 16 Aug '00

16 Aug '00

I have an External method that is used to upload files to a unix file system. Thing is, it seems to be causing more and more memory to be used by Zope. Can anyone give me some pointers on what might be causing this?

Bug zClass subobjects?
by Menard.Jean-Francois＠hydro.qc.ca 16 Aug '00

16 Aug '00

(Second post) (I speak french, sorry for my english!) I created a ZClass, zRow. This class can contain other ZClass: zField_Text, zField_Date, etc. This let me define the columns contained in a zRow. I then defined a Class zTable, wich contains zRows. Question: - In my manage tabs, I needed to have a tab "Define columns". To achieve this, I inserted a ZRow Instance (with id "Definition") in my zTable product definition, and a method called "Define_Columns", containing: <dtml-with Definition> <dtml-var manage_main> </dtml-with> And I defined a view "Define Columns" pointing to that method. When i click on the "Define Columns", I can see the manage screen of the instance "Definition", that's what I wanted. But when I try to add a zField to "Definition" instance, the zField instance is created at the zTable level, not IN "Definition" instance! All the classes are derived from on CatalogAware, ObjectManager. I HAVE to deliver the product for the end of the week, so PLEASE help me!
