python - Django 表单和 django-guardian：显示过滤后的 UserObjectPermissions 列表

Question

我希望管理员能够根据对所述对象可用的权限，将 django-guardian 权限分配/删除给一个人以及它们与项目对象的关系。

屏幕看起来像这样：

该项目在 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)

这目前给了我一个 NameError，我想是因为我在方法self之外使用__init__。我究竟做错了什么？

Answer 1

嗯，这很尴尬。这是答案 - 我几乎得到它：

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()
