问题:

We know there is a value() method of QuerySet, when there is a foreignkey (author, for example), it result like:

[{ 'author_id':3, ... }, ...]

I want a result like:

[{ 'author':{'name':'dave',...}, ... }, ...]

and I tried select_related, but values() won't show the detail of the foreignkey, what shall I do?

回答1:

AFAIK, Django doesn't have builtin support for that. select_related never changes the outcome of a queryset, only the number of queries when you access related object.

You could use DjangoFullSerializers to get something that is similar to what you want.

Implement the unicode method of each Model, and print it.

class Book(..):
    title = models.CharField(..)
    color = models.CharField(...)
    author = models.ForeignKey('Author')
    ...
    def __unicode__(self):
        return u"%s %s %s" %(title, color, author)

class Author(...):
    name = models.CharField(...)
    ...
    def __unicode__(self):
        return name
