RuntimeError: Working outside of application context


Error – RuntimeError: Working outside of application context. in flask app when adding this line “db.create_all()”

The error occurs because you are trying to create the database tables outside of a Flask application context. To resolve this, you can create the database tables within the if __name__ == "__main__" block, after the application has been created and has been added to the context.

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///features.db'
db = SQLAlchemy(app)

class Feature(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    image_url = db.Column(db.String(200), nullable=False)
    feature_page_url = db.Column(db.String(200), nullable=False)
    title = db.Column(db.String(200), nullable=False)
    description = db.Column(db.Text, nullable=False)

def home():
    features = Feature.query.all()
    return render_template("home.html", features=features)

if __name__ == "__main__":
    with app.app_context():
