一种在settings.py中具有django SITEURL常量的方法 [英] a way to have django SITEURL constant in settings.py

问题描述

我来自PHP背景，我知道可以在框架中的大多数地方访问常量，并且我认为在django中也是如此。我也尝试过在django中使用该URL，但是我尝试从django.contrib中使用它。我尝试利用django的Site类并将其导入。但是问题是，在加载settings.py时，我无法导入任何Django contrib。文件。

I am from PHP background, and I know that constants can be accessed at most of places in a framework and I think it is same in django as well. I tried to have that URL too in django but I tried to have it from django.contrib. I tried to utilize django's Site class and imported that. But the problem is that at time of loading settings.py I can't import any django contrib. file.

因此，如何自动拥有可在模板以及其他地方的任何地方使用的SITE URL。最佳方法是什么？是否有任何python实用程序可以这样做？

So how can I have SITE URL automatically that I can use anywhere, in template as well as at other places.What is the best way to do so? Do any python utility can do so?

推荐答案

无论您在settings.py中定义的内容如何，​​例如

Whatever you define in your settings.py, for example

SITE_URL = 'http://www.mydomain.com'

可以使用以下所有与Django相关的代码进行访问：

Can be accessed in all your Django related code with:

from django.conf import settings #this imports also your specific settings.py

print settings.SITE_URL

或者仅 Site.objects.get_current（）。domain

如果您希望能够在模板中访问它，则可以自己创建<一个href = https://docs.djangoproject.com/en/dev/ref/templates/api/#writing-your-own-context-processors rel = noreferrer>模板上下文处理器。将其放入django.conf中的

If you want to be able to access it in the templates, you make your own template context processor. Put this in my_project/content_processor.py

from django.conf import settings
def my_site_url(request):
    return {
        'SITE_URL': settings.SITE_URL,
    }

或者，如果您希望它是动态的：

Or if you want it Dynamic:

from django.conf import settings
def my_site_url(request):
    return {
        'SITE_URL': Site.objects.get_current().domain,
    }

并将其添加到settings.py中的TEMPLATE_CONTEXT_PROCESSORS变量中。

And add it to your TEMPLATE_CONTEXT_PROCESSORS variable in settings.py. It should look similar to that afterwards:

TEMPLATE_CONTEXT_PROCESSORS =("django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.core.context_processors.static",
"django.core.context_processors.tz",
"django.contrib.messages.context_processors.messages",
"my_project.context_processors.my_site_url",
)

并完成。
