django-1.4

问题 I have a Django project where I would need two models to have a foreign key to each other. However this is not possible because two Python files would have to import each other which Python doesn't allow. What is the best way to solve this problem? So my code currently looks like this: countries/models.py: from django.db.models import Model, ForeignKey from users.models import Profile class Country(Model): president = ForeignKey(Profile) users/models.py: from django.db.models import Model,

问题 I am overriding the save method on one of my models: def save(self, *args, **kwargs): self.set_coords() super(Post, self).save(*args, **kwargs) def __unicode__(self): return self.address # set coordinates def set_coords(self): toFind = self.address + ', ' + self.city + ', ' + \ self.province + ', ' + self.postal (place, location) = g.geocode(toFind) self.lat = location[0] self.lng = location[1] However, I only want to run set_coords() once, when the post is being created.

问题 Is there a way of filtering prefetched objects? I need to get the latest() of the prefetched objects but prefetch_related doesn't work if you use latest because the query is changed?

问题 With Django 1.4 and Allauth, I'm trying to have 2 different signup pages. When I say different, I mean 2 different URLs and 'html layouts'. Here's what I did so far. It 'works', but it doesn't pass the 'is_alternate_template' variable to the HTML template: In urls.py: url(r'^accounts/', include('allauth.urls')), url(r'^abc/alternate-signup/?$','project.views.alternate_signup'), in views.py: def alternate_signup(request): from allauth.account import views as account_views is_alternate_template

问题 DeprecationWarning: Function-based generic views have been deprecated; use class-based views instead. I keep getting this warning, when I'm running my site.
