我最近从 1.2 更新到 Django 1.4。
在过渡期间,不推荐使用 set_messages,现在消息 API 已更改为 add_message。基于此页面,我应该使用以下格式:
messages.add_message(request, messages.INFO, 'Hello world.')
但是,我得到了错误global name 'request' is not defined
。有谁知道为什么?
这是我的代码(导致问题的行以粗体显示)
class InviteFriendForm(UserForm):
to_user = forms.CharField(widget=forms.HiddenInput)
message = forms.CharField(label="Message", required=False, widget=forms.Textarea(attrs = {'cols': '20', 'rows': '5'}))
def clean_to_user(self):
to_username = self.cleaned_data["to_user"]
try:
User.objects.get(username=to_username)
except User.DoesNotExist:
raise forms.ValidationError(u"Unknown user.")
return self.cleaned_data["to_user"]
def clean(self):
to_user = User.objects.get(username=self.cleaned_data["to_user"])
previous_invitations_to = FriendshipInvitation.objects.invitations(to_user=to_user, from_user=self.user)
if previous_invitations_to.count() > 0:
raise forms.ValidationError(u"Already requested friendship with %s" % to_user.username)
# check inverse
previous_invitations_from = FriendshipInvitation.objects.invitations(to_user=self.user, from_user=to_user)
if previous_invitations_from.count() > 0:
raise forms.ValidationError(u"%s has already requested friendship with you" % to_user.username)
return self.cleaned_data
def save(self):
to_user = User.objects.get(username=self.cleaned_data["to_user"])
message = self.cleaned_data["message"]
invitation = FriendshipInvitation(from_user=self.user, to_user=to_user, message=message, status="2")
invitation.save()
if notification:
notification.send([to_user], "friends_invite", {"invitation": invitation})
notification.send([self.user], "friends_invite_sent", {"invitation": invitation})
**messages.add_message(request, messages.SUCCESS, "Friendship requested with %s" % to_user.username)**
return invitation
