默认情况下，Django 管理站点显示相关模型/表的所有记录以供查看。如何只显示符合特定条件的记录？

在管理员定义中，您可以定义一个 queryset() 方法，该方法返回该模型管理员的查询集。例如：

class MyModelAdmin(admin.ModelAdmin):
    def queryset(self, request):
        qs = super(MyModelAdmin, self).queryset(request)
        return qs.filter(user=request.user)

那么只有带有 user=request.user 的对象才会在管理中可见。

In your admin definition, you can define a queryset() method that returns the queryset for that model's admin. eg:

class MyModelAdmin(admin.ModelAdmin):
    def queryset(self, request):
        qs = super(MyModelAdmin, self).queryset(request)
        return qs.filter(user=request.user)

Then only objects with user=request.user will be visible in the admin.

我知道这有一个“可接受的答案”，但我只是想把它扔在那里，因为我在追求其他东西时遇到了这个答案，并意识到我有一个我发现并经常使用的替代解决方案，它给了我比它更精细的级别控制接受的答案。

class TestAdmin(admin.ModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
        if db_field.name == "FIELD":
            kwargs["queryset"] = TestModel.objects.filter(test=False)
        return super(TestAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

    def formfield_for_manytomany(self, db_field, request, **kwargs):
        if db_field.name == "FIELDS":
            kwargs["queryset"] = TestModel.objects.filter(test=False)
        return super(TestAdmin, self).formfield_for_manytomany(db_field, request, **kwargs)

I know this has an "accepted answer", but I just wanted to throw this out there since I came across this answer while pursuing something else and realized I had an alternative solution that I found and use often that gives me more granular level control than the accepted answer.

class TestAdmin(admin.ModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
        if db_field.name == "FIELD":
            kwargs["queryset"] = TestModel.objects.filter(test=False)
        return super(TestAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

    def formfield_for_manytomany(self, db_field, request, **kwargs):
        if db_field.name == "FIELDS":
            kwargs["queryset"] = TestModel.objects.filter(test=False)
        return super(TestAdmin, self).formfield_for_manytomany(db_field, request, **kwargs)
