[Zope3-Users] zope.app.catalog doc question

2005-09-30 Thread Duncan McGreggor 
I am curious about the documented catalog method searchResults().  
Starting at line 223 of zope/app/catalog/README.txt (3.1 rc3 download,  
not svn co), there is the following usage of the method:


 result = cat.searchResults(size=5)
 len(result)
2
 list(result) == [o4, o5]
True

When trying to implement this with my own catalog, I got the following  
(partial) traceback:


  File  
/Users/oubiwann/Desktop/2CD/AdytumSolutions/Projects/Zope3Work/ 
zope310_r3/lib/python/accumacsite/browser/homepageview.py, line 18, in  
inventoryInStock

return catalog.searchResults(equipment_in_stock=True)
  File /usr/local/zope310/lib/python/zope/app/catalog/catalog.py,  
line 105, in searchResults

results = self.apply(searchterms)
  File /usr/local/zope310/lib/python/zope/app/catalog/catalog.py,  
line 84, in apply

r = index.apply(index_query)
  File /usr/local/zope310/lib/python/zope/index/field/index.py, line  
99, in apply

return multiunion(self._fwd_index.values(*query))
TypeError: values() argument after * must be a sequence

Indeed, after looking at the code, it seems that instead of writing  
this:


  return catalog.searchResults(equipment_in_stock=True)

I should be writing this:

  return catalog.searchResults(equipment_in_stock=[True])

since apply() does expect the rhs of the parameter to be a sequence.  
With this change, my code now works (no errors, anyway), but I wanted  
to see if this was a misunderstanding on my part or a documentation  
typo...


Thanks,

Duncan

[Zope3-Users] How do I logout from Zope 3 Management Interface?

2005-09-30 Thread Milind Khadilkar 

I have installed Zope 3.1 rc 3. After logging in, I could not find any
logout button. Is it OK to directly shut the browser window ( I am
using Firefox)?
--mk

Re: [Zope3-Users] querying the catalog

2005-09-30 Thread Alen Stanisic 
I think I understand now, you have a page view index.html with view
class HomePageView which looks up a catalog but when you go to the page:

/accumac/index.html

the local catalog

/accumac/++etc++site/default/accumac_catalog

is not being found, but a catalog in the root site is returned.

Unfortunately not sure why this would be happening, I would definitely
expect the local catalog to be returned first.  

Not sure if it will help but whenever I had to look up a catalog I would
only do zapi.getUtility(ICatalog) and I noticed you are also providing a
name and context.  Maybe you need to do this as you have more than one
catalog in your ++etc++site.  I think another thing to make sure is that
your local catalog provides ICatalog interface.  

I also believe that if you are looking up a catalog by name as you seem
to be doing it is not enought for the catalog object to be named
accumac_catalog but you also have to register it as the name ('Register
As' field in New Utility Registration) during catalog creation.  I
usually leave 'Register As' blank as I only ever needed to get catalog
by ICatalog interface only - zapi.getUtility(ICatalog)

  My understanding was that your zapi.getUtility() was not finding your

  /accumac/++etc++site/default/accumac_catalog
 
  I guess the success of the catalog look up depends on what your 
  self.context is when you are
  doing zapi.getUtility(), i.e. where you are looking up the catalog 
  from.  I would expect
  your code to find the catalog when self.context is inside accumac 
  site, but would not
  expect the catalog to be found from inside the other two sites.
 
 Okay, that's what I thought you were talking about. So, to clarify, I 
 am not interesting in finding any content outside of the subs-sites; 
 they are little units in and of themselves, and content searches take 
 place only within the context of a subsite. The problem is (using a 
 specific example) that the catalog in the subsite accumac is not 
 being found. That's the one I want found, and only within the context 
 of the accumac site itself. It *is* finding a catalog, though not the 
 one I want. The one it is finding is at /++etc++site/default (and not 
 /accumac/++etc++site/default).
 
 Thanks for taking the time to understand :-)
