I have developed an application with flask, and I want to publish it for production, but I do not know how to make a separation between the production and development environment (database and code), have you documents to help me or code. I specify in the config.py file the two environment but I do not know how to do with.
class DevelopmentConfig(Config):
"""
Development configurations
"""
DEBUG = True
SQLALCHEMY_ECHO = True
ASSETS_DEBUG = True
DATABASE = 'teamprojet_db'
print('THIS APP IS IN DEBUG MODE. YOU SHOULD NOT SEE THIS IN PRODUCTION.')
class ProductionConfig(Config):
"""
Production configurations
"""
DEBUG = False
DATABASE = 'teamprojet_prod_db'
One convention used is to specify an environment variable before starting your application.
For example
$ ENV=prod; python run.py
In your app, you check the value of that environment variable to determine which config to use. In your case:
run.py
import os
if os.environ['ENV'] == 'prod':
config = ProductionConfig()
else:
config = DevelopmentConfig()
It is also worth noting that the statement
print('THIS APP IS IN DEBUG MODE. YOU SHOULD NOT SEE THIS IN PRODUCTION.')
prints no matter which ENV
you set since the interpreter executes all the code in the class definitions before running the rest of the script.
