[SOLVED] Is there a reason that some keys and values will not load in TOML? (Python config import)

Is there a reason that some keys and values will not load in TOML? (Python config import)

I've set up my flask app to read my config file...

app.config.from_file("../CONFIGS/config.py", lambda f: tomllib.load(f.buffer))
f.write(str(app.config))

when I go to see the output some of the line from the config are there...

MY_VARIABLE = "1"

but

my_variable = "1"

is missing from the output...

Am I missing something?

using the 3.11 built in TOMLLIB with python 3.11

Solution

In Flask, the app configuration system only picks up keys that are in uppercase, so any lowercase settings from your config file get ignored. That's why you're seeing "MY_VARIABLE" but not "my_variable".

Change your config file so that all the setting names are uppercase, like MY_VARIABLE. (or) Or, if you need to keep lowercase names, you can load the file yourself and manually add each setting to app.config in uppercase form.
