When I try to update the users portfolio I receive a runtime error from passing in 'when' as date('now'). Please can someone tell what I should be doing. Here is part of my buy function code.

   # calculate total price
    total = quote["price"]*amount
    cash = db.execute("SELECT cash FROM users WHERE id = :id", id = session["user_id"])[0]["cash"]

    # check if user has sufficient cash and update portfolio
    if(cash >= total):
        db.execute("INSERT INTO portfolio (id, price, number, symbol, when) VALUES (:id, :price, :number, :symbol, date('now'))", id = session["user_id"], price = quote["price"], number = amount, symbol = quote["symbol"])
        db.execute("UPDATE users SETS cash = cash - :price WHERE id = :id", price = amount, id = session["user_id"])
    else:
        return apology("insufficient cash for chosen stock")

    # Redirect user to home page
    return redirect("/")

  • What's the exact error message? Maybe also post the table schema (in sqlite3 finance.db, do .schema portfolio). I think calling your first field id is a bad choice, as this is an id from table users, so user_id would be more appropriate. – Blauelf Jul 10 '18 at 15:29
  • I meant portfolio.id as being misleading, users.id is fine. – Blauelf Jul 10 '18 at 15:34

when is a keyword in sqlite. You'll have to escape it, single-quotes I think eg 'when'(or maybe backticks). Or you could create the table again and rename the column.
