我正在使用 django 1.5.1 和 django social auth 进行社交登录。要获取 facebook 登录 url，我使用这个
from django.template import Template, Context
facebook_url = Template("{% url 'socialauth_begin' 'facebook' %}").render(Context())
只是得到下面的错误。
Template error:
In template <unknown source>, error at line 1
maximum recursion depth exceeded
1 : {% url 'socialauth_begin' 'facebook' %}
它在我的生产服务器和本地开发盒上运行良好，并且 python 和 django 以及 django 社交身份验证版本似乎相同。我试图弄清楚某些库的语法是否发生了变化，其版本在我的测试服务器上可能不同。

更新：
似乎 django-postman 模块导致了这个问题。评论出来摆脱了这个问题。仍然不确定为什么它在开发盒和生产服务器上工作而不是在测试服务器上工作。这是一个临时修复，因为将来我将需要 django-postman 模块，但现在我已经解除了自己的封锁。
