After a week or so of idle i returned to finance and tried to chek my buy function. I bought some stocks of apple(AAPL) but got invalid symbol error, when i tried to use quote(this function always worked) and got same error. I reinstalled helpers file, this didnt help. Here is my code of buy function, but i dont think its me, cos a week ago i could use buy and quote function.
@app.route("/buy", methods=["GET", "POST"])
@login_required
def buy():
"""Buy shares of stock"""
if request.method == "POST":
if lookup(request.form.get("symbol")) == None:
return apology("invalid symbol", 400)
cash = db.execute("SELECT cash FROM users WHERE id = :user_id", user_id = session["user_id"])[0]["cash"]
price = lookup(request.form.get("symbol"))['price']
shares = float(request.form.get("shares"))
symbol = request.form.get("symbol")
if price*shares > cash:
return apology("can`t afford", 400)
db.execute("UPDATE users SET cash = :cash WHERE id = :user_id", cash = cash - price*shares, user_id = session["user_id"])
db.execute("INSERT INTO stocks (user_id, symbol, shares) VALUES (:user_id, :symbol, :shares)", user_id = session["user_id"], symbol = symbol, shares = shares)
db.execute("INSERT INTO history (user_id, action, symbol, price, shares, datetime) VALUES (:user_id, :action, :symbol, :price, :shares, :datetime",
user_id = session["user_id"], action = "buy", symbol = symbol, price = price, shares = shares, datetime = datetime.now().strftime("%Y-%m-%d %H:%M:%S"))
return apology("ITSALIVE")
else:
return render_template("buy.html")
