I can't figure out what is wrong in my code
My python code:
def buy(): """Buy shares of stock"""
if request.method == "GET":
render_template("buy.html")
elif request.method == "POST":
symbol = request.form.get(symbol)
quote = lookup(symbol)
# Check if the symbol is valid
if not quote:
return apology("Invalid symbol", 400)
# Check if the number of shares is an integer greater than 0
shares = request.form.get(shares)
if shares <= 0:
return apology("Invalid number of shares", 400)
# Get the user from ther users database
cash = db.execute("SELECT cash FROM users WHERE id = :user_id", user_id = session.get("user_id"))
username = db.execute("SELECT username FROM users WHERE id = :user_id", user_id = session.get("user_id"))
# Check if the user has enough money
price = quote["price"]
total = price*shares
if total > cash:
return apology("You don't have enough money", 400)
# datetime object containing current date and time
now = datetime.now()
# dd/mm/YY H:M:S
date = now.strftime("%d/%m/%Y %H:%M:%S")
db.execute("INSERT INTO history (symbol, price, qtd, date, username) VALUES (:symbol, :price, :qtd, :date, :username)", symbol=symbol, price=price, qtd=shares, date=date, username=username)
# Update the cash value
update_cash = (cash - total)
db.execute("UPDATE users SET cash=:update_cash WHERE id=:user_id", update_cash=update_cash, user_id=session.get("user_id"))
return redirect("/")
My HTML code:
<form action="/buy" method="post">
<div class="form-group">
<input autocomplete="off" autofocus class="form-control" name="symbol" placeholder="Symbol" type="text">
</div>
<div class="form-group">
<input autocomplete="off" autofocus class="form-control" name="shares" placeholder="Shares" type="number">
</div>
<button class="btn btn-primary" type="submit">Buy</button>
</form>
The Type Error: The view function did not return a valid response. The function either returned None or ended without a return statement.
