Question

class StudentsTeacher(admin.TabularInline):
    form = StudentsTeacher
    model = StudentsTeacher

class Teacher_Admin(admin.ModelAdmin):
    inlines = (StudentsTeacher,)

我想在StudentsTeacher中添加一个带有过滤器的查询集，但它不起作用，内联始终全部显示。

Answer 1

使用get_queryset()方法，您可以覆盖查询集

class Teacher_Admin(admin.TabularInline):
    def get_queryset(self, request):
        qs = super(Teacher_Admin, self).get_queryset(request)
        return qs.filter(<filtering>)

您可以在django docs

中详细了解相关信息

Answer 2

您还可以在表单集中为内联定义自定义查询集

    class StudentTeacherFormset(BaseInlineFormSet):
        self.queryset = StudentsTeacher.objects.filter(<your custom filter>)

    class StudentsTeacher(admin.TabularInline):
        form = StudentsTeacher
        model = StudentsTeacher
        formset = StudentTeacherFormset

    class Teacher_Admin(admin.ModelAdmin):
        inlines = (StudentsTeacher,)

Formset可用于为Django内联生成自定义查询集，而不用在父级admin中呈现子表的所有对象。

但是，如果有人找到解决方案，以便在Django内联中提供类似于列表过滤器的过滤器，请告诉我。
