Django权限复选框形式

我有一个模板，我编辑模型用户的所有基本字段。Django权限复选框形式

现在我想要一个窗体，其中将显示类似复选框样式的所有可用权限。已经分配给用户的应该已经被检查过了。

我有一个form.py，用于编辑用户的表单，但还没有完成权限表单。

class UserSettingsForm(forms.ModelForm): 
class Meta: 
    model = User 
    fields = (
     'username', 
     'first_name', 
     'last_name', 
     'email', 
     'urnik', 
     'ure_na_teden', 
     'rfid', 
     'oddelek', 
     'status_zaposleni', 
    ) 

def __init__(self, *args, **kwargs): 
    self.request = kwargs.pop("request") 
    super(UserSettingsForm, self).__init__(*args, **kwargs) 
    instance = getattr(self, 'instance', None) 
    self.fields['username'].disabled = True 

def save(self): 
    user = super(UserSettingsForm, self).save() 
    return user 

class UserPermissonsForm(forms.ModelForm): 
class Meta: 
    model = Permission 
    fields = (
     'name', 
     'content_type', 
     'codename', 
    )

而且一个views.py：

@login_required 
def uporabnik_uredi(request, username=None): 
user = get_object_or_404(User, username=username) 
uporabnik_form = UserSettingsForm(request.POST or None,request=request, instance=user) 
permissions = [(p.id, p.name) for p in Permission.objects.filter(user=user)] 
data = { 
    'uporabnik' : user, 
    'form' : uporabnik_form, 
    'from': request.GET.get('from', None), 
    'permissions' : permissions, 
} 

if request.POST: 
    if uporabnik_form.is_valid(): 
     user = uporabnik_form.save() 
     next = request.GET.get('next', None) 
     return redirect(next) 
return render(request, "sifranti/uporabniki/uredi.html", data)

，也是一个模板，只是为了看看当前哪些权限分配给用户：

<div class=""> 
    {% for id, name in permissions %} 
     {{ id }} - {{ name }} <br> 
    {% endfor %} 
</div>

这是我该怎么办，但我使用了MultipleSelect，我想你可以将其应用于复选框。

class EditUserForm(forms.ModelForm): 

def __init__(self, *args, **kwargs): 
    super(EditUserForm, self).__init__(*args, **kwargs) 

    def get_label(obj): 
     permission_name = str(obj).split('|')[2].strip() 
     model_name = permission_name.split(' ')[2].strip() 
     return '%s | %s' % (model_name.title(), permission_name) 

    User = get_user_model() 
    content_type = ContentType.objects.get_for_model(User) 
    self.fields['user_permissions'].queryset = Permission.objects.filter(content_type=content_type) 
    self.fields['user_permissions'].widget.attrs.update({'class': 'permission-select'}) 
    self.fields['user_permissions'].help_text = None 
    self.fields['user_permissions'].label = "Label" 
    self.fields['user_permissions'].label_from_instance = get_label 

def save(self, commit=True): 
    user_instance = super(EditUserForm, self).save(commit) 
    user_instance.save() 
    user_instance.user_permissions.set(self.cleaned_data.get('user_permissions')) 
    return user_instance 

class Meta: 
    model = get_user_model() 
    fields = ['email', 'first_name', 'last_name', 'user_permissions'] 

    widgets = { 
     'email': forms.EmailInput(attrs={'class': 'form-control', 'style': 'width: 300px;'}), 
     'first_name': forms.TextInput(attrs={'class': 'form-control', 'style': 'width: 300px;'}), 
     'last_name': forms.TextInput(attrs={'class': 'form-control', 'style': 'width: 300px;'}), 
     'user_permissions': forms.SelectMultiple(attrs={'style': 'width: 350px; height: 200px;'}) 
    }

希望这会有所帮助，祝你好运！
