Django表单和django-guardian：显示UserObjectPermissions的过滤列表

Question

我希望管理员能够根据所述对象可用的权限，为一个人分配/删除django-guardian权限以及它们与Project对象的关系。

屏幕看起来像这样：

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)

这当前给了我一个NameError，我想因为我在self方法之外使用__init__。我做错了什么？

Answer 1

嗯，这很令人尴尬。这就是答案 - 我几乎拥有它：

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()
