如何从django管理员内联数据过滤？

Question

我想在管理面板中过滤Django ForeignKey模型。它具有学生资料，并且可以添加主题标记。但是问题是学生想在获得所有学科列表的同时添加自己的分数。但是我想当10年级的学生添加她的分数，而他会看到她的10年级的主题列表。我该如何实施？

class MarksSubjectInstanceInline(admin.TabularInline):
    model = Marks
    fk_name = 'std_name'
    extra = 2
    exclude = ['subject_gradepoint', 'subject_gpa','subject_gpa_sub', 'subject_marks', 'subject_total_marks']


@admin.register(StudentInfo)
class StudentAdmin(admin.ModelAdmin):


    list_filter = ('std_class', 'std_gender', 'std_group',)
    list_display = ('std_name', 'std_class', 'std_group', 'std_gender', 'std_roll')
    inlines = [MarksSubjectInstanceInline]

    search_fields = ('std_name','std_roll','std_group')


    exclude = ['std_total_marks', 'std_gpa','std_grade_point_total_sum','std_marks_with_fail_sub', 'std_grade_point_total_subject_avg', 'std_fail_subject','school_rank','class_rank']
