Question

我正在尝试控制管理员项目条目，其中非超级用户帐户无法保存日期属性超过2天的ChannelStatus模型输入。我需要让用户，以便我可以检查请求是否是一个reqular或超级用户，但无法实现这一点。

我已经尝试过“request.user.is_superuser”，“user.is_superuser”，“self.user.is_superuser”和“self.request.user.is_superuser”，但似乎都没有。

class ChannelStatusValidForm(forms.ModelForm):
    class Meta:
            model = ChannelStatus
    def clean(self):
        cleaned_data = self.cleaned_data
        mydate = cleaned_data.get("date")
        today = date.today()
        if request.user.is_superuser:## here is the problem
            return cleaned_data
        elif (today - timedelta(days=2)) > mydate:
            raise forms.ValidationError("Invalid date, maximum 2 days allowed.")
        else:
            return cleaned_data

从another question添加（并调整）Daniel Roseman的答案：

class ChannelStatusValidForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request', None)
        super(MyForm, self).__init__(*args, **kwargs)


    def clean(self):
        cleaned_data = self.cleaned_data
        mydate = cleaned_data.get("date")
        today = date.today()
        if self.request.user.is_superuser:
            return cleaned_data
        elif (today - timedelta(days=2)) > mydate:
            raise forms.ValidationError("Invalid date, maximum 2 days allowed.")
        else:
            return cleaned_data

并在您看来：

myform = ChannelStatusValidForm(request.POST, request=request)

有一种方法可以在不创建其他管理员视图的情况下实现此目的：get_form()中的 use a form metaclass：

class ChannelStatusValidForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request', None) # Now you can access request anywhere in your form methods by using self.request.            
        super(ChannelStatusValidForm, self).__init__(*args, **kwargs)

    def clean(self):
        cleaned_data = self.cleaned_data
        mydate = cleaned_data.get("date")
        today = date.today()
            request = self.request
        if request.user.is_superuser:
            return cleaned_data
        elif (today - timedelta(days=2)) > mydate:
            raise forms.ValidationError("Invalid date, maximum 2 days allowed.")
        else:
            return cleaned_data
    class Meta:
            model = ChannelStatus

class ChannelStatusAdmin(admin.ModelAdmin):
    form = ChannelStatusValidForm    
    def get_form(self, request, obj=None, **kwargs):
        AdminForm = super(ChannelStatusAdmin, self).get_form(request, obj, **kwargs)
        class ModelFormMetaClass(AdminForm):
            def __new__(cls, *args, **kwargs):
                kwargs['request'] = request
                return AdminForm(*args, **kwargs)
        return ModelFormMetaClass
