Django 模板语法错误

Question

我在开发服务器上遇到了一个模板语法错误，这个错误只在我的开发服务器上出现，而在本地的Django测试服务器上运行得很好。

这是错误信息：

Caught SyntaxError while rendering: invalid syntax (urls.py, line 1)

还有HTML代码：

<li><a href="{% url plan.views.profile %}">Plan Details</a></li>

这是个人资料视图：

@login_required
def profile(request):
...

这是错误追踪信息：

我检查过我的urls.py文件，没问题。第一行是：

from django.conf.urls.defaults import *

Answer 1

这里有一个可能的解决办法。你的视图文件的路径似乎是 /django/myapp/plan/views.py：

File "/django/myapp/plan/views.py" in profile
    121.             }, context_instance=RequestContext(request) )

如果你的 Python 路径已经设置好包含 /django，那么你需要把你的模板/html 改成：

{% url myapp.plan.views.profile %}

如果不是这样的话，根据 bx2 的建议，你可能需要检查一下你的 urls.py 文件，看看里面有没有语法错误。

Answer 2

在你的urls.py文件中，使用带名字的链接，方法是通过url函数，比如这样。

urlpatterns = patterns('your_app.views',
    url(r'^somehiing/$', 'your_view_function', name='my_view'),
)

然后在你的模板中使用 {% url my_view %} 这个代码。

如果这样做还是不行，可以把你的urls.py贴过来，可能只是一些小的语法错误。
