Django:如何在管理表单中获取当前用户? [英] Django: How to get current user in admin forms?

问题描述

在 Django 的 ModelAdmin 中，我需要显示根据用户拥有的权限定制的表单.有没有办法将当前用户对象放入表单类中，以便我可以在其 __init__ 方法中自定义表单?

In Django's ModelAdmin, I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, so that i can customize the form in its __init__ method?

我认为将当前请求保存在本地线程中是可能的，但这将是我最后的手段，因为我认为这是一种糟糕的设计方法.

I think saving the current request in a thread local would be a possibility but this would be my last resort because I'm thinking it is a bad design approach.

推荐答案

这是我最近为一个博客所做的:

Here is what i did recently for a Blog:

class BlogPostAdmin(admin.ModelAdmin):
    form = BlogPostForm

    def get_form(self, request, **kwargs):
         form = super(BlogPostAdmin, self).get_form(request, **kwargs)
         form.current_user = request.user
         return form

我现在可以通过访问 self.current_user

这是一个旧答案，最近看它我意识到get_form方法应该修改为:

This is an old answer, and looking at it recently I realized the get_form method should be amended to be:

    def get_form(self, request, *args, **kwargs):
         form = super(BlogPostAdmin, self).get_form(request, *args, **kwargs)
         form.current_user = request.user
         return form

(注意添加了*args)
