Migration files not created

[kimzwegz]

hello:
I have created the migration depository folder but when I run the migration command, the migration scripts are not created.

### this is the main py file 

import os
from flask import Flask
from flask_migrate import Migrate
from flask_sqlalchemy import SQLAlchemy


## set directory to work with
basedir = os.path.abspath(os.path.dirname(__file__))

## set the app name = app
app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///'+os.path.join(basedir,'data.sqlite')
app.config['SQLALCHEMY_TRA CK_MODIFICATIONS'] = False

db = SQLAlchemy(app)
migrate = Migrate(app, db)

class user(db.Model):

    __tablename__ = 't_users'

    uname = db.Column(db.String, primary_key=True , index=True)
    email = db.Column(db.String(64) , index=True , unique=True)
    upass = db.Column(db.String(128), index=True, unique=True)

    def __init__(self, uname, email, upass):
        self.uname = uname
        self.email = email
        self.upass = upass

#terminal commands to generate migration depository

export FLASK_APP=flask_exc_82_dba1.py
python3 -m flask db init

## migration depository created 

python3 flask db migrate -m "user"

## generate migration file note that I am not working in a virtual environment that's why I call they python 3 command .. the FLASK_APP is also not picking the original file name so I am using the actual py file name

python3 flask_exc_82_dba1.py migrate -m "user"


## output from terminal

<SQLAlchemy engine=sqlite:////Users/karimkhalil/python_docs/web_dev/Examples/data.sqlite>

Use python3 -m flask db ... when you send your migrate command:

python3 -m flask db migrate -m "user"

If that does not work, please provide the complete output of the command.

Miguel .. thank you very much for your prompt reply.
the above command indeed worked. I was also executing the command in VS Code terminal but not from the directory where the main py file is stored which caused the above script not to return anything.
