如何让用户从change_view和add_view进入验证

Question

我尝试使用 request.user 对象的验证来限制 django 管理站点中特定用户的某些行的更新。我的印象是我需要重写 ModelAdmin change_view 方法以将请求对象传递到表单。我已经查看了 django.contrib.admin.options 中的change_view方法，但是作为一个刚接触django的人，我无法理解change_view方法中我需要进行这些修改的位置。任何指向正确方向的指针都会很棒。

class IssuesAdmin(admin.ModelAdmin):
    def change_view(self, request, object_id, extra_context=None):
        #modify lines to pass request to form

    form = IssuesAdminForm


class IssuesAdminForm(forms.ModelForm):
    class Meta:
        model = Issues

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


    def clean_product(self):
        if self.request.user.name=='someone'
            return self.cleaned_data["product"]
        else:
            raise forms.ValidationError("Nope!")

class IssuesAdmin(admin.ModelAdmin):
def change_view(self, request, object_id, extra_context=None): #remember to edit also add_view()... etc
    self.form.request = request

form = IssuesAdminForm

class IssuesAdminForm(forms.ModelForm):
    class Meta:
       model = Issues

    def __init__(self, *args, **kwargs):

       self.request = # do what you need ;)
       super(IssuesAdminForm, self).__init__(*args, **kwargs)


def clean_product(self):
    if self.request.user.name=='someone'
        return self.cleaned_data["product"]
    else:
        raise forms.ValidationError("Nope!")
