Question

如何在编辑对象时过滤django管理页面中下拉字段的内容？例如：

class Question(models.Model):
    creator = models.ForeignKey(User)
    body = models.CharField(max_length=200)
    category = models.ForeignKey(Category)

class Category(models.Model):
    name = models.CharField(max_length=200)
    creator = models.ForeignKey(User)

class QuestionAdmin(TeacherModelAdmin):
    fieldsets = [
        (None, {'fields': ['body', 'category']}),
    ]
    #Filter by request.user == creator ?

Answer 1

您可以在管理

中覆盖formfield_for_foreignkey方法

class QuestionAdmin(TeacherModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
    if db_field.name == "category":
        kwargs["queryset"] = Category.objects.filter(creater=request.user)
    return super(QuestionAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

Answer 2

看起来似乎有没有官方方式。

但是，您可以使用BaseModelAdmin中定义并由ModelAdmin继承的Swiper API挂钩。解决方案看起来像这样：

class QuestionAdmin(TeacherModelAdmin):
    fieldsets = [
        (None, {'fields': ['body', 'category']}),
    ]

    def get_field_queryset(self, db, db_field, request):
        # Bahaviour for your field
        if db_field.name == 'category':
            return db_field.remote_field.model.filter(creator=request.user)
        # Default behaviour unchanged
        return super(OrderAdmin,self).get_field_queryset(db, db_field, request)

在应用此解决方案之前，如果您真的需要它，请三思而后行，不要成为官方API的一部分意味着当有人更改此挂钩而不提前添加弃用警告时，您可能会遇到麻烦。
