custom command

[dp Audiovisual]

Hello, I need to create a "custom command" that uploads all the Json files of a folder within the project to the postgres database. Help, I'm learning.

Hi Dp,

Basically, you'll have to:

1. Add the command; the documentation explains quite well how to make a new command: https://docs.djangoproject.com/en/2.0/howto/custom-management-commands/

2. In that command, you'll have to read a directory. That's pure python and you could use something like walk https://docs.python.org/3/library/os.html?highlight=os#os.walk, although there are other commands. Check the `os` and `os.path` modules.

3. Reading a JSON is easy peasy with the JSON module: https://docs.python.org/3/library/json.html?highlight=json#module-json

4. And to add the values in PostgreSQL, you'll need to have your model defined (https://docs.djangoproject.com/en/2.0/topics/db/models/) and, with that, you just create records and `.save()` them.
