Hi.
Once again thanks for all your invaluable advice to me so far. Now, I'm
battling context_processors.
I really struggle to find a good example that can help me understand how to
use them.
They seem quite helpful to a lot of stuff I plan to do.
I think I got the configuration in settings.py and @register right as my tag is
accepted as registered.
What baffles me is whether to include "request" as argument to my context
processor GetItemDictionary()
The error I get now (without declaring request as an argument) is
"GetItemDictionary() takes 0 positional arguments but 1 was given"
With request as argumetn to GetItemDictionary(request) I get this error:
'GetItemDictionary' did not receive value(s) for the argument(s): 'request'
Should I pass request to my GetItemDictionary somewhere in my view, or is
that done automagically by the template?
I realise that I've probably done something wrong elsewhere, but I'm at a
loss to guess where ...
I suspect that the @register.simple_tag stuff I do may be the culprit as
the tag may not be simple.
thanks, Mikkel
>From project/app/templatetags/items_extra.py
from django import template
register = template.Library()
@register.simple_tag()
def GetItemDictionary():
# For now pass a hardcoded dictionary - replace with query later
return {
'year': {'name': 'year', 'readable': 'Year', 'urlname': 'year_list'
},
'region': {'name': 'region', 'readable': 'Region', 'urlname':
'region_list' },
'location': {'name': 'location', 'readable': 'Location', 'urlname':
'location_list' },
}
