Hey,
I'm basically trying to filter a foreign key (using limit_choices_to)
by an user (just like in this thread
http://groups.google.com/group/django-users/browse_thread/thread/8006b7e493ef877d/79d5c10c3abab725?lnk=st&q=limit_choices_to+threads&rnum=2#79d5c10c3abab725)
The model is quite simply, as you may guess:
class Practica(models.Model):
asignatura = models.ForeignKey(Asignatura, blank=False,
limit_choices_to = {'owner' : ##current_user##})
class Asignatura(models.Model):
owner = models.ForeignKey(User, blank=False,
limit_choices_to={'is_staff__exact' : 1})
The first limit_choices_to is the one which is not working. I tried
threadlocals
(http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser)
unsucessfully ( limit_choices_to = {'owner' : get_current_user()}) ). I
realized that the evaluation of get_current_user() wasn't done during
runtime but just once at the very beggining.
So I guessed that a lazy version of get_current_user should be needed
for that (as Luke suggested in this other thread:
http://groups.google.com/group/django-users/browse_thread/thread/5d89dc0c2aa3927b/f19dba6f48bb6060?lnk=gst&q=lazyuser&rnum=1#f19dba6f48bb6060)
And then I discovered LazyUser in django/contrib/auth/middleware.py
(http://code.djangoproject.com/browser/django/trunk/django/contrib/auth/middleware.py?rev=3754)
It is not documented any where, and not found very much information
about. Neither it is used in django trunk code. So I tried to use it
with limit_choices_to like somekind of LazyDate(), but with, again, no
results. Also I'm not pretty sure what kind of object it returns.
Maybe some django-guru could help me in this??
I'm very surprised this is not a hot django topic and not so much
information can be found in google about it. I can't believe that no
one has needed this before...
thanks in advance!
