问题 here is the models page In this picture, only the title shows up on here, I used: def __unicode__(self): return self.title; here is the each individual objects How do I show all these fields? How do I show all the fields in each Model page? 回答1: By default, the admin layout only shows what is returned from the object's unicode function. To display something else you need to create a custom admin form in app_dir/admin.py . See here: https://docs.djangoproject.com/en/dev/ref/contrib/admin/

问题 I want to be able to update a many-to-many field on a model, when the name of the field is stored in a variable. This is relatively easy for a normal field (with kwargs in the constructor), or even a foreign key, but not so for a many-to-many field. Here's the situation: class Book(models.Model): title = models.CharField(max_length=30) authors = models.ManyToManyField(Author) field_name = 'title' new = Book(**{field_name:'My Book'}) # This sets title to mybook new.save() my_authors = Author

问题 I am building a simple social network in django. In the "home" of my social, I have the list of all posts published by all users, with author and publishing date.

However, as I click on it, it shows me the list of all posts published by its author (this also works when I click on the author link of the post). So both www.mysocial.com/posts/by/ciccio/7/ and www.mysocial.com/posts

问题 i'm new into Python/Django programming and i got stuck with something in a personal project that i'm doing.
