Re: [Zope] Mark Pilgrim's Feed Parser in Zope

2006-07-26 Thread KJZZ Webmaster 
Dieter,

Appreciate your help.

I found a way to test if the ExternalMethod really returned a dict here:

http://infrae.com/mailman_/pipermail/silva-dev/2004q2/001091.html

And you were right! This is not seen as as a valid dictionary (nor is it
seen as a string):

stuff = container.externalmethod(feedurl=feedurl)
test = same_type(stuff, {})
print test
return printed

returns 0

However, interestingly enough, if I copy and paste the all the text that
is returned by the external method into the script, I am able to confirm
that it is a dictionary:

stuff= {'lastbuilddate': u'Mon, 24 Jul 2006 12:06:18 EDT', u'subtitle': 'U.S.',
u'generator': 'NPR/RSS Generator 2.0 etc...'}

test = same_type(stuff, {})
print test
return printed

returns 1

Also, I tried to render the copied text from the external method using the
page template, and received a different error message:

TypeError: string indices must be integers (see the attached traceback).

I don't know if this last test will be useful, but I thought I'd give it
a try.

Do you know if there is a way of changing the data type of an object?

Do you know if there is a listing of data types that I could test for?

Thanks kindly,

John T.

There is an easy, but potentially dangerous way to turn a string 
representative of a python dictionary back into a 'real' python 
dictionary... only do this if you are sure of the contents of the 
dictionary:  in an external method:


def string2dict(instr):
   dict = {}
   dict['__builtins__'] = None
   return eval(instr, dict)

In this case you are using the Python syntax to create a dictionary, 
so it's not a surprise when it *is* a dictionary...


Are you sure that your external method returns this *text*? It seems 
that you are looking at the string representation of some 
dictionary-like object. You can convert any dictionary-like object 
into a true dictionary using the builtin function dict:


  d = dict(an_object_that_acts_like_a_dictionary)

This page template renders an rss feed that has been transformed into a

(feedscript) which calls an external method (newsfeed) which uses Mark 
Pilgrim's feed parser to parse the xml into a python data type.

The object might look like a dictionary but it probably is not.

Ensure that your ExternalMethod really returns a dict (or other
simple data structure).

[Zope] Mark Pilgrim's Feed Parser in Zope

If I run the python script or the external method directly (via the test 
tab in the ZMI) I have no problem viewing all the properties of the rss 
feed.


However, if I use the page template, I still receive this error.

I've tried to get around this by running the python script using a proxy 
role of manager or owner, but I still receive the same error.


Any suggestions you might have are appreciated.

[Zope] Mark Pilgrim's Feed Parser in Zope
