从管理员验证类获取用户 [英] getting the user from a admin validation class

问题描述

我正在尝试控制管理项目条目，其中非超级用户帐户无法保存具有超过2天的date属性的ChannelStatus模型输入。我需要得到用户，以便我可以检查请求是否是一个reqular或超级用户，但是无法实现这一点。

I am trying to control admin item entry where non-super user accounts can't save a ChannelStatus model input that has a date attribute which is older than 2 days. I need to get the user so that I can check if the request is a reqular or a super user but couldn't achieve this.

我已经尝试过请求。 user.is_superuser，user.is_superuser，self.user.is_superuser和self.request.user.is_superuser，但似乎没有效果。

I have already tried "request.user.is_superuser", "user.is_superuser", "self.user.is_superuser" and "self.request.user.is_superuser" but none seem to work.

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

Adding (and adjusting) Daniel Roseman's answer from another question:

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

并且在您的视图中：

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