如何使用字符串[django]访问python模块变量 [英] How to access a python module variable using a string [ django ]

问题描述

我有一个django应用程序，其模块名为"app"
现在，该模块具有一个名为"urls.py" 的文件，该文件具有一个名为"HOME_URL "

I have a django application, with a module called "app"
Now this module has a file called "urls.py" which has a variable called "HOME_URL"

我要做什么?

app_label = "app"
url = __import__(app_label).urls.HOME_URL
print url

那显然是行不通的，但是我希望你能得到我想要做的.如果没有，请发表评论，我将编辑问题以包含更多信息.

That obviously doesn't work, but I hope you got what I'm trying to do, If not please comment I will edit the question to contain more info.

推荐答案

您可以使用

You can use import_module to load a module relative to the root of a django project.

from django.utils.importlib import import_module
app_label = "app"
url = import_module("%s.urls" % app_label).HOME_URL 

这应该在您的django项目中或在 ./manage.py shell 中工作.

This should work within your django project, or in ./manage.py shell.
