如何在Django模型中获得ManyToMany字段的类？
[英]How do I get the class of a ManyToMany field in django models?
问题描述
I have some fields in a model that are ManyToMany, I want the ManyToMany class itself, when I only have the field name. 
我的模型中有多个字段ManyToMany，当我只有字段名称时，我想要ManyToMany类本身。 Is there any way I can retrieve it? 有什么办法可以找回它？

如果model_obj是Model类的实例，该实例定义了一个名为foom2m的ManyToManyField，则可以执行以下操作：
related_model = model_obj.__class_.foom2m.field.rel.to
