With the get_queryset() method you can override the queryset

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

You can read more about it in the django docs

This does NOT work. get_queryset() has no effect on the number of records available in the inlined view. – hipertracker Sep 25 '19 at 11:51

You can also define your custom queryset in the formset for inlines

    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 can be used to generate a custom queryset for django inlines instead of rendering all the objects of child table in parents admin.

However if anyone finds a solution for providing a filter in django inlines similar to list filter, please let me know.

This is invalid code. "form = StudentsTeacher" raises: "name 'StudentsTeacher' is not defined" — hipertracker, Sep 25 '19 at 11:48
