from flask_sqlalchemy import SQLAlchemy


app = Flask(__name__)
app.secret_key = "secreat key"

app.config['SQLALCHEMY DATABASE_URI'] = 'mysql://root:@localhost/cust_51_stock_list'
app.config['SQLALCHEMY TRACK_MODIFICATIONS'] = False

db =   SQLAlchemy(app)

class Stocks(db.Model):
    id = db.Column(db.Integer, primary_key = True)
    tiker = db.Column(db.String(15))
    price = db.Column(db.String(20))
    qty = db.Column(db.String(20))

    

@app.route('/')
def home():
    tkrs = Stocks.query.all()
    all_data = ['1','2','3','4','5','6','7']
    return render_template('home.html', stk_data=tkrs)

# @app.route('/getdata', methods = ['POST'])
