Hello.
I'm using Django v1.
When I want to add a column in an admin list page, I just create a
function in the associated model class and add it to the
"list_display" tuple in the same model class. For instance, if I
wanted to create a link to a reference id that would show up as a
column, I would do something like this:
def link_to_reference(self):
try:
id = Reference.objects.get(id=self.referenced_by_id).id
except Reference.DoesNotExist:
return 'Does not exist.'
return '<a href="/resourcesguide/resource/reference/''+\
str(id)+'">'+str(id)+'</a>'
link_to_reference.short_description = 'Referral ID'
link_to_reference.allow_tags = True
Then do this:
list_display = ('somefield1', 'somefield2' ... 'link_to_referrer')
This always works well for me. Now I am trying to do something similar
on an admin change form. Instead of using the "list_display" tuple, I
try the "fields" tuple like this:
fields = (('Section 1', {'fields': ('field1', 'field2' ...
'link_to_reference'})))
I get a "FieldDoesNotExist" exception.
Does anyone know a (simple) way perform this type of function-based
sudo-field creation on the admin change form?
Thanks in advance.
