除了ManyToMany之外，是否有允许多种选择的Django ModelField？

[英]Is there a Django ModelField that allows for multiple choices, aside from ManyToMany?

原文 2010-02-15 16:29:20 8 3 python/ django/ forms

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. 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。 A select-multiple or a list of checkboxes would be great. 选择多个或复选框列表会很棒。 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. 但是，我不需要这个值列表中的项目来特别引用任何模型......我只想要一个简单明了的项目文本列表，因此我不认为ManyToManyField是我的那个我正在寻找。 What's the quickest way to do this in Django? 在Django中最快的方法是什么？

There is a django snippet which does just this: multiple choice model field . 有一个django片段就是这样做的：多选模型字段。 It says: 它说：

Usually you want to store multiple choices as a manytomany link to another table. 通常，您希望将多个选项存储为另一个表的manytomany链接。 Sometimes however it is useful to store them in the model itself. 然而，有时将它们存储在模型本身中是有用的。 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. 此字段使用常规CHOICES属性实现模型字段和附带的表单字段，以将多个选项存储为逗号分隔的值列表。

Django-multiselectfield does what you require: Django-multiselectfield可满足您的需求：

It's inspired by the snippet that Alexander mentioned. 它的灵感来自亚历山大提到的片段。

This django snippet accomplishes the same with a much smaller footprint. 这个django片段以更小的占地面积实现了这一目标。
