如何处理可重用Django应用中的命名空间网址 [英] How to Deal with Namespacing URLs in a Reusable Django App

问题描述

我一直在努力使用可重用的Django应用倒转网址。这是我的问题的基本布局。

可重复使用的应用程序：

urls.py 文件具有以下模式：

  url（r '^ object-list / $'，ObjectListView.as_view（），name ='object-list'）
  

在可重用的应用程序的 views.py 中的某个地方，有以下反向调用：

 code> reverse（'object-list'）
  

---

我的项目

在我想使用此应用程序的项目中，我有另一个冲突的视图名称，所以我命名空间应用程序的URL如下所示：

  url（r'^ app-stuff /'，include（'app.urls'，namespace = 'app'））
  

---

：

这样做会导致应用程序内的所有反向调用都抛出一个 NoReverseMatch 异常什么时候要查找对象细节，因为URL现在具有名称 app：object-detail 。

我可以访问有问题的应用程序，所以我可以修改它对反向的调用，但我想做它以一种不涉及硬编码命名空间的方式。我已经阅读了 current_app 和命名空间参数到包含函数，但我不太明白他们是否会帮助解决我遇到的问题。

任何建议，您都可以非常感谢。 >

解决方案

我在阅读 Django的URL解析文档更为紧密。

如果你有可重用的应用程序称为 myapp ，您可以将属性 app_name 添加到其URL配置中，以赋予其应用程序命名空间。示例：

 ＃myapp / urls.py 
 
 app_name ='myapp'
 
 urlpatterns = [
 url（r'^ index / $'，IndexView.as_view（），name ='index'）
] 
  pre> 
 
 
现在，即使应用程序的URL包含如下：
 ＃project / urls.py 
 
 urlpatterns = [
 url（r'^ myapp /'，include（'myapp.urls'，namespace ='random-namespace'）） 
] 
  
 ...仍然可以使用 （'myapp：index'）。
 
 
 
如果你想更详细地看到这个，我创建了一个小例子的GitHub回购。

指定 urls.py  app_name 属性>只适用于Django 1.9及更高版本。对于Django 1.8，您必须使用 include（）函数中的 app_name 参数。
 
I have been struggling with reversing URLs with a reusable Django app. Here's the basic layout of my problem.

Reusable App:

In the urls.py file it has the following pattern:
url(r'^object-list/$', ObjectListView.as_view(), name='object-list')
Somewhere in the reusable app's views.py, there is the following reverse call:
reverse('object-list')




My Project:

In the project where I want to use this app, I have another conflicting view name, so I namespace the app's URLs like so:
url(r'^app-stuff/', include('app.urls', namespace='app'))




The Problem:

This has the consequence of causing all reverse calls within the app to throw a NoReverseMatch exception when it tries to lookup object-detail, because the URL now has the name app:object-detail.

I have access to the app in question, so I can modify the calls it makes to reverse, but I would like to do it in a way that doesn't involve hardcoding a namespace. I have read the documentation on the current_app and namespace arguments to the include function but I don't quite understand if they would help solve the issue I'm having.

Any suggestions you might have are greatly appreciated.
解决方案
I solved this after reading Django's docs on URL resolution more closely.

If you have a reusable app called myapp, you can add the property app_name to its URL configuration to give it an application namespace. Example:
# myapp/urls.py

app_name = 'myapp'

urlpatterns = [
    url(r'^index/$', IndexView.as_view(), name='index')
]
Now, even if the app's URLs are included like so:
# project/urls.py

urlpatterns = [
    url(r'^myapp/', include('myapp.urls', namespace='random-namespace')),
]
...the urls are still accessible using reverse('myapp:index').

If you would like to see this in more detail, I created a small GitHub repo with an example.

Edit:

Specifying the app_name property in urls.py only works on Django 1.9 and up. For Django 1.8, you have to use the app_name parameter in the include() function.
