db = SQLAlchemy(app)
class User(db.Model):
__tablename__ = 'User'
id = db.Column(db.Integer,primary_key=True,autoincrement=True)
Username = db.Column(db.String(20),nullable=False)
Password= db.Column(db.String(20), nullable=False)
db.create_all()
@app.route('/')
def base():
return render_template('base.html')
@app.route('/login/')
def login():
return render_template('login.html')
@app.route('/register/')
def register():
return render_template('register.html')
@app.route('/question/')
def question():
return render_template('question.html')
if __name__ == '__main__':
app.run(debug=True)
