Hello, I was wondering if the concept of Category existed in Zope. In particular: is it possible to classify an object in several categories? Regards, Almo

context in a Product's python code (not Python Script)
by John K. Hohm 05 Dec '02

05 Dec '02

I have a Page Template and Python Script that are working fairly well together to generate a navigational menu on my site, and now I want to make them part of a product. I have tried this: class CMS(Folder): # ... # old "menu" Page Template copied to www/menu.zpt file security.declareProtected('View', 'menu') menu = PageTemplateFile('www/menu', globals()) menu._owner = None security.declareProtected('View', 'menu_items') def menu_items(self, levels=2, REQUEST=None): context = self._getContext # body of old "menu_items" Python Script copied here def _getContext(self): while 1: self = self.aq_parent if not getattr(self, '_is_wrapperish', None): return self I cannot seem to find the way to get the bindings a Python Script has, particularly the context binding. As you can see, I tried grabbing the _getContext method from Script, but it gives me the root Zope object, instead of the object that is being requested and having menu called on it from the web. What am I doing wrong?

Comparing directories & dumb question
by BZ 05 Dec '02

05 Dec '02

I am trying to write a snippet of code that will figure out what main directory you are in and display a different banner based on that. Should be simple as heck, well... it has been driving me crazy. Here is what I have and I know I am missing one stupid line of code or something. dtml-let section="_.string.split(_.string.lower(_.string.split(URL, '/')[3]), '.')"> <dtml-call "REQUEST.set('section', section)"> </dtml-let> <dtml-if section> <dtml-if "section=='folder_name'"> show new header <dtml-else> do something else </dtml-if> </dtml-if section> And this is the output and why it won't match which I think is because the first one is in a list. (??!) ['folder_name'] = folder_name Any help? BZ

I have a script called 'stuff' which takes on parameter. I'd like to call it directly from a url. I've been googling but can see any syntax examples. How does one pass parameters to a script directly from a url from a browser? -- David Bear College of Public Programs/ASU Mail Code 0803

How to check with ZOPE/Python if file "x.html" exists in path container.REQUEST.PARENTS[0].getPhysicalPath()?
by Thomas Duebendorfer 05 Dec '02

05 Dec '02

I simply want to check in a ZOPE/Python script, whether the file "x.html" exists at the exact path defined by container.REQUEST.PARENTS[0].getPhysicalPath(). And I want to make sure that ZOPE does NO TRAVERSAL, i.e. does not look in folders above the given path in case the file was not found. The statement path = container.REQUEST.PARENTS[0].getPhysicalPath() returns correctly something like: path = "('', 'silva', 'kom', 'web', 'topic1', 'subtopic1a')" The Python script "checkFile.py" to check for the file will reside at /silva/kom/checkFile.py and is called from a tal:define="fileExists python:here.checkFile('x.html'))" in /silva/kom/web/main.html. Any idea how I can do that? Thanks for your answers. Regards, Thomas
