如果我正确理解你，你想做的是覆盖get_form方法为ModelAdmin。基于来自django文档的示例，它将如下所示：

  class MyUserAdmin（admin.ModelAdmin）：
 def get_form（self，request，obj = None，** kwargs）：
 self.exclude = [] 
如果没有request.user.is_superuser：
 self.exclude.append（'Permissions'）#here！ 
 return super（MyUserAdmin，self）.get_form（request，obj，** kwargs）
 

现在你可能需要一点点攻击，也可能会覆盖保存方法。我不久以前做过类似的事情，它并不那么复杂（文档很棒）。

可能有一个更简单的解决方案，但你的问题是一般的，你没有不要分享你的用户模型，所以我无法告诉你如何解决这个问题。我希望这有帮助！

I have a simple MyUser class with PermissionsMixin. user.is_superuser equals True only for superusers. I'd like to be able to do something similar to this in my admin.py:

    if request.user.is_superuser:
        fieldsets = (
            (None, {'fields': ('email', 'password')}),
            ('Permissions', {'fields': ('is_admin','is_staff')}),
            ('Place', {'fields': ('place',)}),
            ('Important dates', {'fields': ('last_login',)}),
        )
    else:
        fieldsets = (
            (None, {'fields': ('email', 'password')}),
            #('Permissions', {'fields': ('is_admin','is_staff')}),
            ('Place', {'fields': ('place',)}),
            ('Important dates', {'fields': ('last_login',)}),
        )

Basically I want my users to be able to create other users, but not give them admin or stuff permissions. Only superusers should be able to do that.

If I understand you correctly, what you want to do is override the get_form method for the ModelAdmin. Base on the example from django documentation, it would look something like this:

class MyUserAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        self.exclude = []
        if not request.user.is_superuser:
            self.exclude.append('Permissions') #here!
        return super(MyUserAdmin, self).get_form(request, obj, **kwargs)

Now you might need to hack around a little and maybe override the save method as well. I did something similar not long ago, it's not so complicated (and the docs are fantastic).

There might be a simpler solution but your question is kinda general and you didn't share your user model, so I can't tell you exactly how to work this out. I hope this helps!
