Django forms和django-guardian:显示UserObjectPermissions的过滤列表

Question

我希望管理员能够分配/删除django-guardian权限给一个人，以及他们如何与项目对象相关，基于可用于该对象的权限。

屏幕如下所示：

项目在URL中提供，视图可以看到。我创建了一个自定义表单，它将项目作为输入，如下所示：

from django import forms
from django.contrib.auth.models import User
from guardian.shortcuts import get_perms_for_model

class ProjectAssignmentForm(forms.Form):
    def __init__(self, *args, **kwargs):
        self.p = kwargs.pop('project')
        self.perms = [(x, x) for x in get_perms_for_model(self.p)]
        super(ProjectAssignmentForm, self).__init__(*args, **kwargs)
        self.fields['permission'].widget = forms.CheckboxSelectMultiple()

    user = forms.ModelChoiceField(queryset=User.objects.all())  
    permission = forms.ChoiceField(choices=self.perms)

这给了我一个NameError，我想是因为我在__init__方法之外使用了self。我做错了什么？

好吧，这太尴尬了。这就是答案--我差一点就做到了：

from django import forms
from django.contrib.auth.models import User
from guardian.shortcuts import get_perms_for_model

class ProjectAssignmentForm(forms.Form):
  def __init__(self, *args, **kwargs):
    super(ProjectAssignmentForm, self).__init__(*args, **kwargs)
    self.fields['permission'].widget = forms.CheckboxSelectMultiple(
        choices=[(x, x) for x in get_perms_for_model(kwargs.pop('project'))])

  user = forms.ModelChoiceField(queryset=User.objects.all())  
  permission = forms.MultipleChoiceField()
