A friend emailed me about the setting of django environment variables. He should want to set up a separate module under the django project to synchronize the relevant data to the database.

In this way, by running the file, you can use the simple model operation ready-made by django to achieve the purpose of synchronizing data. Here is a screenshot of his question:

From the error prompt, it should be that the environment variable is not set properly, which makes it impossible to make use of django-related modules and data.

My reply to him was:

Import os, sys

Dirname = os.path.dirname (_ _ file__) # current working directory

Sys.path.append (dirname)

Import settings # Assumed to be in the same directory.

Setup_environ (settings)

From django.db import connection

In this way, the current file can call the relevant modules and properties of the system. I hope it will be helpful to you.
