Flask failed to load configuration from config.py - flask

Question

My __init__.py file
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from config import app_config
db = SQLAlchemy()
def create_app(config_name):
app = Flask(__name__, instance_relative_config=True)
app.config.from_object(app_config[config_name])
app.config.from_pyfile('config.py')
db.init_app(app)
#app.route('/')
def index():
return 'Hello, user'
return app
I will find tutorial for flask
build crud app flask
My config.py file:
import os
# Set path for our db
basedir = os.path.dirname(os.path.abspath(__file__))
class Config:
DEBUG = True
class DevConfig(Config):
DEBUG = True
SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir,
'bookshell.db')
SQLALCHEMY_ECHO = True
SQLALCHEMY_TRACK_MODIFICATIONS = False
class ProdConfig(Config):
DEBUG = False
class TestConfig(Config):
DEBUG = True
app_config = {
'development': DevConfig,
'production': ProdConfig,
'testing': TestConfig
}
run.py file
import os
# Import from app/__init__
from app import create_app
config_name = os.getenv('FLASK_CONFIG', 'development')
app = create_app(config_name)
if __name__ == '__main__':
app.run()
So, I tried to configure my own config.py file, but I get an error
FileNotFoundError: [Errno 2] Unable to load configuration file (No such file or directory): '/Users/yevhensurzhenko/Desktop/Simple_login_form/instance/config.py'
But when I change some configuration, and when try to reload page it give me
405 error method not allowed
or
app.config.from_object(app_config[config_name])
KeyError: <flask.cli.ScriptInfo object at 0x1038a5b70>
So, I made some changes, like
In config.py add
app_config = {
..
'default': DevConfig
}
In __init__.py create instance dir.
from instance import config
And now I get output from func that I create in __init__.py, in create__app()...
#app.route('/')
def index():
return 'Hello, user'
But, FLASK_CONFIG not change, it work only production, wtf:(
