Why i do it?

I'm still doing a RestAPI with FastAPI with React Native, and when you need to obtain from your database with nosql an array, you can't convert in the simplest way array to Literal[] and you can't validate data in a flexible way. To save before data an after apply to your new values to use it, from your database to validate with Pydantic.

How to use it

from pydantic import BaseModel
from to_literal.v1 import toLiteral

hoursL = toLiteral([
    '9:00',
    '9:30',
])

class testLiteral(BaseModel):
    hours: hoursL


#   Good Example:

test = testLiteral(hours='9:30')
print(test.model_dump())

#   Result:
#   { 
#       'hours': '9:30'
#   }



#   Bad Example -> ERROR:

test = testLiteral(hours='10:30')
print(test.model_dump())
