如何在可重用的应用程序中使用django的命名空间url [英] How to use namespace urls with django in a reusuable app

问题描述

我有一个django应用程序，一个论坛应用程序，它有模板。在这些模板中，有指向应用程序部分的URL。例如，thread_list模板具有如下所示的每个线程的链接：

  {％线程中的线程％} 
< ; a href ={％url forum_thread thread％}> {{thread.title}}< / a> 
 {％endfor％} 
  

事情是，我不喜欢打电话给我urlsforum_thread。我更喜欢线程，并使用django的命名空间功能。 forum_thread可能在项目中的其他位置（命名空间冲突）中使用。它将如下所示：

  {％线程中的线程％} 
< a href ={％url论坛：线程线程％}> {{thread.title}}< / a> 
 {％endfor％} 
  

但这不是正确的做法这个。这里的文件有点不清楚。

我希望这个应用程序可以重复使用，易于配置。但我也想使用最好的标准。我不想让用户指定自己的命名空间名称，然后让他们在每个模板中编辑每个单个的URL。

我该怎么做网址在这个应用程序中？

解决方案

从我可以收集的内容可以使用{％url forum：thread thread％}已经描述过。命名空间似乎被定义为两个变量，命名空间和app_name。

如果您在urls.py中执行以下操作：

  url（r'^ / forum /'，include（'forum.urls'，namespace ='forum'，app_name ='forum'）），
 url（r'^ / foo /'，include（'forum.urls'，namespace ='foo'，app_name ='forum'）），
 url（r'^ / bar /'，include .urls'，namespace ='bar'，app_name ='forum'）），
  

，这定义了3个应用程序论坛，foo，bar和默认（具有namespace == app_name）的实例。

论坛：线程，它使用当前上下文来确定要使用哪一个上下文 - 如果你在命名空间'foo'中使用它，否则它会回退到默认值。

如果任何人能够澄清Django如何决定当前命名空间/应用程序将是非常有帮助的。我现在将其分类为黑魔法。

对于名称空间和app_name之间的实际区别的一些澄清也将是有帮助的 - 我有可能完全颠倒。目前的文档是非常模糊的。

注意：我有这个工作的初始请求，但是我目前无法为AJAX请求做这个工作 - 这些请求总是使用由于某些原因，默认实例。

I have a django app, a forum app, that has templates with it. In those templates, there are urls that point to parts of the app. For instance the thread_list template has links to each thread like so:

{% for thread in threads %}
    <a href="{% url forum_thread thread %}">{{thread.title}}</a>
{% endfor %}

The thing is, I don't really like calling my urls "forum_thread". I prefer just "thread" and using the namespace feature of django. "forum_thread" may be used somewhere else in the project (namespace collision).So it will look like this:

{% for thread in threads %}
    <a href="{% url forum:thread thread %}">{{thread.title}}</a>
{% endfor %}

but this doesn't feel like the correct way to do this. The docs are kind of unclear here.

I want this app to be reusable and easy to configure. But I also want to use the best standards. I don't want to have the to make the user specify their own namespace name, and then have them edit every single url in each template.

How should I do urls in this app?

解决方案

From what I can gather you should be able use {% url forum:thread thread %} as you've described. Namespaces always seem to be defined with two variables, namespace and app_name.

If you then do the following in urls.py:

url(r'^/forum/', include('forum.urls', namespace='forum', app_name='forum')),
url(r'^/foo/', include('forum.urls', namespace='foo', app_name='forum')),
url(r'^/bar/', include('forum.urls', namespace='bar', app_name='forum')),

In my understanding, this defines 3 instances of the app 'forum', 'foo', 'bar', and the default (which has namespace==app_name).

When you reverse forum:thread, it uses the current context to determine which one to use- if you are in namespace 'foo' it will use that, otherwise it will fall back on the default.

If anyone is able to clarify how Django decides what the 'current' namespace/app is that would be very helpful. I currently categorise it as 'black magic'.

Some clarification on the actual difference between namespace and app_name would also be helpful- it's possible that I have this totally reversed. The current docs are highly ambiguous.

Note: I have this working for initial requests, but I'm currently unable to make this work for AJAX requests- those always use the default instance for some reason.
