在django模型中实现每个领域的隐私的最佳方式 [英] best way to implement privacy on each field in model django

问题描述

我正在为用户在模型的现场级别提供隐私设置。所以用户可以决定他想要显示哪些数据以及他想隐藏哪些数据。

I am trying to provide privacy settings at the model's field level for users. So a user can decide which data he wants to display and which data he wants to hide.

示例：

class Foo(models.Model):
    user = models.OneToOneField("auth.User")
    telephone_number = models.CharField(blank=True, null=True, max_length=10)
    image = models.ImageField(upload_to=get_photo_storage_path, null=True, blank=True)

我想为用户提供一个选项，以选择他想要显示的字段，以及他不显示的字段。
考虑用户不想显示电话号码，所以他应该有选项。

I want to provide an option to the user to select the fields which he wants to display and which he doesn't. Consider a user doesn't want to display telephone_number, so he should have the option for that.

哪个是最好的方法？

推荐答案

您可以在模型中创建一个 CommaSeparatedIntegerField 字段，并使用它来存储用户想要隐藏的field_names（表示field_name的整数）。

You can create a CommaSeparatedIntegerField field inside the model, and use it to store a list of field_names (Integers that denote a field_name) that the user wants to hide.

您可以在models.py中的一个常量之间创建field_names和整数之间的映射。并检查用户检查的字段名称。

You can create a mapping between the field_names and integers as a constant inside your models.py. And check whichever field_names are those the the user had checked.

示例映射：

FIELD_NAME_CHOICES = (
    (1, Foo._meta.get_field('telephone_number')),
    (2, Foo._meta.get_field('name')),
    .
    .
)
