Is there a Django ModelField that allows for multiple choices, aside from ManyToMany?
提问by int3
I'd like the user to be able to make multiple selections via the admin interface, and store the result as a list of comma-separated values. A select-multiple or a list of checkboxes would be great. However, I don't need the items in this list of values to refer to any models in particular... I just want a text list of items, plain and simple, hence I don't think the ManyToManyField is the one I'm looking for. What's the quickest way to do this in Django?
我希望用户能够通过管理界面进行多项选择，并将结果存储为逗号分隔值列表。选择多个或复选框列表会很棒。但是，我不需要这个值列表中的项目来特别引用任何模型......我只想要一个文本项目列表，简单明了，因此我不认为 ManyToManyField 是我的我在找。在 Django 中执行此操作的最快方法是什么？

There is a django snippet which does just this: multiple choice model field. It says:
有一个 django 片段可以做到这一点：多项选择模型字段。它说：
Usually you want to store multiple choices as a manytomany link to another table. Sometimes however it is useful to store them in the model itself. This field implements a model field and an accompanying formfield to store multiple choices as a comma-separated list of values, using the normal CHOICES attribute.
通常，您希望将多个选项存储为指向另一个表的多条链接。然而，有时将它们存储在模型本身中很有用。该字段实现了一个模型字段和一个伴随的表单字段，以使用普通的 CHOICES 属性将多个选择存储为逗号分隔的值列表。

make sure to update those imports since they are pre version 1.0
确保更新这些导入，因为它们是 1.0 版之前的
