django - 覆盖 Django 管理中的默认查询集

Question

我的一个模型有一个 deleted 标志，用于全局隐藏对象:

class NondeletedManager(models.Manager):
    """Returns only objects which haven't been deleted"""

    def get_query_set(self):
        return super(NondeletedManager, self).get_query_set().exclude(deleted=True)

class Conversation(BaseModel):
    ...
    deleted = models.BooleanField(default=False)
    objects = NondeletedManager()
    all_conversations = models.Manager() # includes deleted conversations

如何覆盖 Django 管理模块使用的默认查询集以包含已删除的对话？

Answer 1

您可以 override get_queryset模型管理类中的方法。

class MyModelAdmin(admin.ModelAdmin):
    def get_queryset(self, request):
        qs = super().get_queryset(request)
        if request.user.is_superuser:
            return qs
        return qs.filter(author=request.user)

注意在 Django<=1.5 中该方法被命名为 queryset。
