Pass variable to blueprint?

Question

Python

Good day, I will describe my problem. I have a file in it flask app initialization:
config.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from source.admin import admin


app = Flask(__name__, template_folder = 'assets', static_folder='static', static_url_path='/static/admin')


app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://lie:*****@localhost/database'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['SQLALCHEMY_NATIVE_UNICODE'] = 'utf-8'
db = SQLAlchemy(app)


app.register_blueprint(admin)
  

if __name__ == '__main__':
  app.run(debug = True, host='localhost', port=5000)

Also in this file there is a variable of interest to me - db, which initializes SQLAlchemy.
And as you noticed, I have a blueprint, I need to pass a variable there db, how to do this?
__init__.pyI don’t want to do it, although I think I don’t have much choice ...
If there is any other way, then please tell me about it, thanks in advance!

Answer 1

i need to pass db variable there

where is it there? If in the model file, then

from app import db

#пример модели
class Page(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(512))
