Config.get returning default value without cast(value) about python-decouple HOT 4 CLOSED

Try list instead of []. It's a callable and should work.

Sorry. I misread default for cast. Can you provide the error message and/or a failing test?

from python-decouple.

  File ".../settings.py", line 36, in <lambda>
    cast=lambda v: [s.strip() for s in v.split(',')])
AttributeError: 'list' object has no attribute 'split'

decouple will call cast(default), in this line. It just seems strange.

Hum... ok.

So we have a design decision to discuss. It seems that everything starts with: What is default?

Today, default is the fallback string value for an undefined option. So if you don't define the ALLOWED_HOSTS option, it will use the default as input for cast.

This enables you to have shorter config files/env by defining sane default values on your python code. Example:

ALLOWED_HOSTS = config('ALLOWED_HOSTS', default='127.0.0.1', cast=csv())

In the above case, even if you don't define ALLOWED_HOSTS on your config file/env it should work fine.

What you seem to be questioning is: Should default be the end python value or should we have another parameter for that?

I don't know.

The purpose of decouple is to make it easy to load config from text data files/env. Maybe we could improve the documentation to clarify this.

What do you think about it?
