如何使用相同的数据设置不同站点的Django项目？ [英] How do you setup a Django project with different sites using the same data?

问题描述

我正在查看Django网站的文档：

I'm currently looking at the the documentation for Django sites:

http://docs.djangoproject.com/en/dev/ref/contrib/sites/#ref-contrib-sites

其中说明了如何将内容与多个网站相关联。所使用的示例是LJWorld.com和Lawrence.com。

which explains how to associate content with multiple sites. The example used is LJWorld.com and Lawrence.com.

上述Django项目结构如何？每个站点都是自己的应用程序，例如：

What does the Django project structure look like for the above? Is each site an app on its own, for instance:

project/
    manage.py
    settings.py
    urls.py
    ljworld/
        models.py
        views.py
    lawrence/
        models.py
        views.py

如果ljworld有 SITE_ID = 1 ，而劳伦斯 SITE_ID = 2 ， SITE_ID 变量必须在 ljworld / settings中显式设置。 py 和 lawrence / settings.py ？

If ljworld has SITE_ID=1 and lawrence has SITE_ID=2, does the SITE_ID variable has to be explicitly set in ljworld/settings.py and lawrence/settings.py?

如何运行dev服务器不管是ljworld还是Lawrence？

How do you run the dev server of either ljworld or lawrence?

更新：

共享内容在上面。如果有不同的网站共享相同的内容，应该怎么做？我真的需要n个不同服务器上的n个不同的Django项目，所有这些都连接到同一个数据库服务器？

I used two sites with shared content in the above. What should be done if there are n different sites who are sharing the same content? Do I really need n different Django projects on n different servers, all connected to the same database server?

此外，如果我需要在settings.py中进行更改应该影响所有这些网站，手动更改这些文件将是非常繁琐的。

Moreover, if I need to make a change in settings.py which should affect all those web sites, it will be very tedious to change each of those files manually.

推荐答案

不，每个网站是不是自己的应用程序;每个网站都是自己的项目。整个想法是具有（完全或部分）共享内容的不同项目。所以你可能有一个结构，如：

No, each site is not an app on its own; each site is a project on its own. The whole idea is to have different projects with a (fully or partially) shared content. So you might have a structure such as:

ljworld/
    manage.py
    settings.py
    urls.py
    ljworld_specific_app1/
    ...
lawrence/
    manage.py
    settings.py
    urls.py
    lawrence_specific_app1/

您通常会使用两台Web服务器来投放项目 - 尽管通常都会参考相同的DB服务器。当然，您也可以在两个项目之间共享应用程序 - 只需将它们保留在服务器的PYTHONPATH中。

You would normally use two Web servers to serve the projects - though normally both would refer to the same DB server. Naturally you can also have apps which are shared between the two projects - just keep them somewhere in the server's PYTHONPATH.

编辑：

两个Web服务器当然不一定意味着两个不同的服务器。他们可能是在同一个Web服务器实例下运行的两个虚拟主机 - 你甚至可以将两个项目映射到同一虚拟主机下的两个不同的目录。

"Two Web servers" of course doesn't necessarily mean two physically different servers. They could well be two virtual hosts running under the same Web server instance - heck, you could even map the two projects to two different directories under the same virtual host.

共享设置，您可以使用与共享应用程序相同的技术。有一个global_settings模块，其中包含PYTHONPATH中某处的共享设置，并从每个settings.py导入。

For shared settings, you could use the same technique as for shared apps. Have a global_settings module which contains the shared settings available somewhere on the PYTHONPATH and import it from each of the settings.py.

如果你想要一些真正的黑客，你可以大概甚至可以删除所有不同的项目，只使用一个，并创建一个中间件，即时更改设置。但我会建议反对。

And if you wanted something really hackish, you could probably even drop all the different projects, use just one and create a middleware that changes settings on the fly. But I would advise against it.
