导入失败并出现奇怪的错误
我得到:
/blog/post/test 处的模板语法错误 渲染时捕获 NameError: 全局名称“forms”未定义
为此代码定义全局名称“forms”:
forms.py
from dojango.forms import widgets
from django.contrib.comments.forms import CommentForm
from Website.Comments.models import PageComment
class PageCommentForm(CommentForm):
title = widgets.TextInput()
rating = widgets.RatingInput()
def get_comment_model(self):
return PageComment
def get_comment_create_data(self):
# Use the data of the superclass, and add in the title field
data = super(PageComment, self).get_comment_create_data()
data['title'] = self.cleaned_data['title']
return data
models.py
from Website.CMS.models import Author, Rating
from django.db.models import CharField, ForeignKey
from django.contrib.comments.models import Comment
class PageComment(Comment):
title = CharField(max_length=300)
parent = ForeignKey(Author, related_name='parent_id', null=True)
author = ForeignKey(Author, related_name='author_id')
def __unicode__(self):
return self.title
class CommentRating(Rating):
comment = ForeignKey(PageComment)
__init__.py
from Website.Comments import *
def get_model():
return models.PageComment
def get_form():
return forms.PageCommentForm #error here
直接在 init.py 中导入表单会导致:
属性错误:“模块”对象没有 属性“评论”
这是堆栈跟踪,错误似乎来自 dojango,但这实际上没有意义:

评论应用位于已安装的应用中。 我应该怎么办?
编辑: 如果我尝试直接使用 import forms
包含表单,我会得到以下结果:

删除对 dojango 的任何引用可以解决该问题。
I get:

importing form directly inside init.py results in:
AttributeError: 'module' object has no

Here's the stack trace, the error appears to be coming from dojango but that doesn't really make sense:

The Comments app is in the installed apps.
What should I do?

If I try to include forms directly with import forms
I get this:

Removing any reference for dojango solves the problem.

这是 dojango 中的一个错误。
我会报告的。
This is a bug in dojango.
I will report it.
将以下内容放入 __init__.py 中:
