向我的Django网站添加安全性问题 [英] Adding security questions to my Django site

问题描述

我需要向用户询问两个安全问题及其相应的答案。安全问题将由我提供，因此将是某种< select> 。我创建了一个模型来存储名为 UserProfile 的用户配置文件。看起来像这样：

I need to ask the user for two security questions and their corresponding answers. The security questions will be provided by me, so it will be some kind of <select>. I created a model to store the user profile named UserProfile. It looks like:

class UserProfile(models.Model):
    phone1 = models.CharField(help_text='Primary phone number')
    phone2 = models.CharField(help_text='Secondary phone number', blank=True)
    ...

我可以这样做：

SECURITY_QUESTIONS_CHOICES = (
    ('PN', 'What is your telephone number?'),
    ('BF', 'What is the full name of your best friend?'),
    ...
    )

并将以下两个字段添加到我的模型中：

and add the following two fields to my model:

question1 = models.CharField(choices=SECURITY_QUESTIONS_CHOICES)
question2 = models.CharField(choices=SECURITY_QUESTIONS_CHOICES)

但我希望能够修改安全问题列表，所以我也希望它也可以成为一个模型。

but I want to be able to modify the list of security questions, so I want it to be a model too.

我的问题是：

具有两个指向同一模型的字段的最佳方法是什么？

• 只有一个字段（例如问题），该字段与ManyToMany关系 SecurityQuestion ，并在注册表格中将数字限制为 2 ？


• 具有两个字段（ question1 和 question2 ），其中每个字段都是一个 ForeignKey 到 SecurityQuestion ？

• Having only one field (eg. questions) which is a ManyToMany relationship to SecurityQuestion, and restricting the number to 2 in the registration form?
• Having two fields (question1 and question2) where each one is a ForeignKey to SecurityQuestion?

推荐答案

我希望为所有安全问题创建一个单独的模型。

I would prefer create a separate model for all security questions. It gives you flexibility.

class SecurityQuestions(models.Model):
    class Meta:
        db_table = 'security_questions'
    id = models.AutoField(primary_key=True)
    question = models.CharField(max_length = 250, null=False)

class UserProfile(models.Model):
    ----
    ----
    user_questions = models.ManyToManyField(SecurityQuestions, through='SecurityQuestionsInter')


class SecurityQuestionsInter(models.Model):
    class Meta:
        db_table = 'security_questions_inter'

    profile = models.ForeignKey(Profile)
    security_questions = models.ForeignKey(SecurityQuestions)
    answer = models.CharField(max_length = 250, null=False)
