Sure! You can add a new column to the Entry_Post class to store the user's ID as a foreign key. First, you'll need to create a relationship between the Entry_Post and User classes using db.ForeignKey and db.relationship. Here's the updated models.py file:
from app import db
from datetime import datetime
class Entry_Post(db.Model):
id = db.Column(db.Integer, primary_key=True)
timestamp = db.Column(db.DateTime, index=True, default=datetime.utcnow)
posttype = db.Column(db.Integer, index=True) # 0 means Summarize from Text, 1 means from URL...
url = db.Column(db.String(2048), index=True) # "0" for Summarize from Text; else URL string
text2summarize = db.Column(db.String(214748364), index=True)
text2summarize_hash = db.Column(db.String(64), index=True) # Added new column for hash value
openAIsummary = db.Column(db.String(214748), index=True)
user_id = db.Column(db.Integer, db.ForeignKey('user.id')) # New column for user_id foreign key
user = db.relationship('User', backref='entry_posts') # Relationship between Entry_Post and User
def __repr__(self):
return '<Entry_Posts {}>'.format(self.id)
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
oauth_id = db.Column(db.String(128), unique=True, nullable=False)
name = db.Column(db.String(100), nullable=False)
email = db.Column(db.String(120), unique=True, nullable=False)
picture = db.Column(db.String(256), nullable=True)
created_at = db.Column(db.DateTime, default=datetime.utcnow)
last_login = db.Column(db.DateTime, default=datetime.utcnow)
def __repr__(self):
return '<User {}>'.format(self.email)Now, the Entry_Post class has a new column user_id, which is a foreign key referencing the id column in the User class. The db.relationship function creates a relationship between the two classes, allowing you to access the user who created an entry post and all the entry posts created by a user.
After making these changes, you'll need to create a new migration and apply it to update your database schema. If you're using Flask-Migrate, you can do this by running:
flask db migrate -m "Add user_id to Entry_Post"
flask db upgradeThis will generate a new migration script and apply the changes to your database.
To incorporate Twitter's OAuth capability and user roles, you can follow these steps:
Install Flask-Dance and Flask-Login for OAuth and user session management:
pip install Flask-Dance Flask-LoginModify the User class in models.py to add a role column for user roles:
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
oauth_id = db.Column(db.String(128), unique=True, nullable=False)
name = db.Column(db.String(100), nullable=False)
email = db.Column(db.String(120), unique=True, nullable=False)
picture = db.Column(db.String(256), nullable=True)
role = db.Column(db.String(32), default='User') # New column for user roles
created_at = db.Column(db.DateTime, default=datetime.utcnow)
last_login = db.Column(db.DateTime, default=datetime.utcnow)
def is_admin(self): # Helper method to check if the user is an admin
return self.role == 'Admin'
def __repr__(self):
return '<User {}>'.format(self.email)Update your app.py or init.py file to set up Twitter OAuth with Flask-Dance, and use Flask-Login for session management:
from flask import Flask, redirect, url_for, flash
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from flask_login import LoginManager, UserMixin, current_user, login_user, logout_user
from flask_dance.contrib.twitter import make_twitter_blueprint, twitter
# Initialize app, database, and other components
app = Flask(__name__)
app.config['SECRET_KEY'] = 'your-secret-key'
app.config['SQLALCHEMY_DATABASE_URI'] = 'your-database-uri'
db = SQLAlchemy(app)
migrate = Migrate(app, db)
login_manager = LoginManager(app)
login_manager.login_view = 'login'
# Configure Twitter OAuth
app.config['TWITTER_OAUTH_CLIENT_KEY'] = 'your-twitter-client-key'
app.config['TWITTER_OAUTH_CLIENT_SECRET'] = 'your-twitter-client-secret'
twitter_blueprint = make_twitter_blueprint()
app.register_blueprint(twitter_blueprint, url_prefix='/login')
# Models
from models import User, Entry_Post
@login_manager.user_loader
def load_user(user_id):
return User.query.get(int(user_id))
# Routes
@app.route('/login')
def login():
if not twitter.authorized:
return redirect(url_for('twitter.login'))
resp = twitter.get('account/verify_credentials.json')
if resp.ok:
oauth_id = str(resp.json()['id'])
user = User.query.filter_by(oauth_id=oauth_id).first()
if user is None:
user = User(
oauth_id=oauth_id,
name=resp.json()['name'],
email=resp.json()['screen_name'] + '@twitter.com', # Using screen_name as email
picture=resp.json()['profile_image_url']
)
db.session.add(user)
db.session.commit()
login_user(user)
flash('Logged in successfully.', 'success')
return redirect(url_for('index'))
else:
flash('Failed to log in with Twitter.', 'danger')
return redirect(url_for('login'))
@app.route('/logout')
def logout():
logout_user()
flash('You have been logged out.', 'success')
return redirect(url_for('login'))
# Other routes and functionsMake sure your templates use the current_user variable provided by Flask-Login to display the user's information and conditionally display content based on the user's role: Modify your routes and views to check for user roles when necessary:
@app.route('/admin-dashboard')
def admin_dashboard():
if not current_user.is_authenticated or not current_user.is_admin():
flash('You do not have permission to access this page.', 'danger')
return redirect(url_for('index'))
# Your admin dashboard logic goes here
return render_template('admin_dashboard.html')
# Other routes and functionsUpdate your templates to use the current_user variable provided by Flask-Login to display the user's information, and conditionally display content based on the user's role. For example, in your base template, you can display different navigation options based on the user's role:
<!-- base.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<!-- meta tags, title, styles, etc. -->
</head>
<body>
<nav>
<!-- Navigation options for all users -->
{% if current_user.is_authenticated %}
{% if current_user.is_admin() %}
<!-- Additional navigation options for admin users -->
<a href="{{ url_for('admin_dashboard') }}">Admin Dashboard</a>
{% endif %}
<a href="{{ url_for('logout') }}">Logout</a>
{% else %}
<a href="{{ url_for('login') }}">Login with Twitter</a>
{% endif %}
</nav>
{% block content %}
{% endblock %}
</body>
</html>Make sure to replace placeholders like 'your-secret-key', 'your-database-uri', 'your-twitter-client-key', and 'your-twitter-client-secret' with appropriate values. You can also customize the email address format for Twitter users and the user role checks according to your requirements.
