django - WSGIRequest错误使用django_model_comments

Question

很抱歉发布另一个与错误相关的问题:

'WSGIRequest' object has no attribute 'find'

但我真的找不到答案。

我正在尝试使用 django_model_comments应用程序，它扩展了 Django 包含的评论应用程序。执行了页面上的所有内容，但是在运行服务器时，我得到以下信息:

Template error:

Exception Type: AttributeError at /feed/1
Exception Value: 'WSGIRequest' object has no attribute 'find'

错误发生在使用模板标签时:

html = "{% load model_comment_tags %} \
        {% get_comment_form for feed as post_form %}\
        {% render_comment_form post_form %}"
t = template.Template(html)
html = t.render(RequestContext(request, {'feed': private_feed}))

我检查了我所有的中间件，应用程序的顺序，删除了 .pyc 文件，并在模板中进行了各种实验。

Answer 1

django_model_comments 库中有一个错误，因为 here他们传递 HttpRequest 对象，而不是 Url 类的字符串 here是预期的，因此它应该在请求对象上调用 build_absolute_uri() 方法，然后将字符串传递给 Url 类。

所以基本上替换

unicode(Url(request))

与

unicode(Url(request.build_absolute_uri()))
