来自另一个应用程序的 django 模板 url [英] django template url from another app

问题描述

我必须错过一些愚蠢的东西.我在模板中有一个 {% url %}，其中的操作来自另一个应用程序.它不起作用，但我不知道使用其他应用的视图函数是否有什么不同，或者我只是在做一些愚蠢的事情.

I have to be missing something silly. I have a {% url %} in a template where the action is from another app. It isn't working but I have no clue if there is something different about using view functions from other apps or if I am just doing something silly.

call/template/call/file.html

call/template/call/file.html

    <form action="{% url 'upload_image' %}"></form>

图片/urls.py

from .views import PictureList, PictureCreate, PictureDetail, PictureUpdate, PictureDelete, upload_image

...
url(r'^upload_image/$', upload_image, name='upload_image'),
...

图片/view.py

def upload_image( request ):
    print 'IN IMAGE UPLOAD'
    print request

我得到的只是:

NoReverseMatch at /call/4/

Reverse for 'upload_image' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

推荐答案

当在来自不同应用程序的 URL 上调用 reverse() 时，你应该使用它的命名空间"版本，就像这样:

When calling reverse() on an URL that comes from a different application, you should use its "namespaced" version, like so:

{% url 'app_name:app_url' %}

在您的具体情况下，这转化为:

In your specific case, that translates to:

{% url 'picture:upload_image' %}
