python - 进行一项调查，告诉用户他们的大学专业匹配。使用 django 和 python

Question

首先，我正在做的项目应该给用户一个多项选择测验/调查，让他们知道什么大学专业最适合他们，并根据他/她选择的答案。我的问题主要是如何将答案和专业联系起来，以便在用户完成专业时选择。如果在理解我试图解释的内容时有任何问题，请告诉我。欢迎所有建议和批评我真的想在我的编程中变得更好。我基本上是想让我的程序在链接中执行此操作。 https://www.luc.edu/undergrad/academiclife/whatsmymajorquiz/

管理员.py

 class AnswerInline(admin.TabularInline):
    model = Answer
    extra = 3
    max_num = 4

class QuestionInline(admin.TabularInline):
    model = Question
    inlines = [AnswerInline]
    extra = 19


class QuestionAdmin(admin.ModelAdmin):
    
    inlines = [AnswerInline]


    

class QuizAdmin(admin.ModelAdmin):
    inlines = [QuestionInline]



admin.site.register(Question, QuestionAdmin)
admin.site.register(Answer)
admin.site.register(Major)
admin.site.register(Quiz, QuizAdmin)

此外，我第一次真正对网站、数据库等做任何事情。代码看起来也有点奇怪（尤其是在视图中）b/c 我试图整合来自另一个项目的代码来提供帮助。在contactForm 视图之后，我开始尝试。我会继续尝试自己解决这个问题，但随着我的最后期限临近，这是我能想到的唯一寻求帮助的选择。
