django模板网址从另一个应用程序 [英] django template url from another app

问题描述

我必须缺少一些愚蠢的东西。我在模板中有一个{％url％}，其中的操作来自另一个应用。它不工作，但是我不知道如果使用其他应用程序的视图功能有所不同，或者我只是做一些愚蠢的事情。

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'），
...

picture / view.py

  def upload_image（request）：
打印'IN IMAGE UPLOAD'
打印请求
  

我所得到的是：

  NoReverseMatch at / call / 4 / 
 
反向'upload_image'与参数'（）'和关键字参数'{}'找不到。 0模式尝试：[] 
  




解决方案

您应该使用其命名空间版本，如下所示：



  {％url'app_name：app_url'％} 
  

在你的具体情况下，这意味着：

  {％url'图片：upload_image'％} 
  




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

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

picture/urls.py

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

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

picture/view.py

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

All I ever get is:

NoReverseMatch at /call/4/

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

解决方案

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' %}

In your specific case, that translates to:

{% url 'picture:upload_image' %}
