pset7 is making me crazy. I have huge problems just from the beginning. Register is working, quote is working but Here is another problem in buy:
Buy is writing data to history, reducing cash in users, but when I try to write data to user portfolio i receive this:
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) near ",": syntax error [SQL: "SELECT * FROM portfolio WHERE user_id= 16, symbol= 'aapl'"]
I don't know what is near ",". Mayby is another stupid mistake like missing letter or something (i'm making a lot of them...).
Here is my buy code:
@app.route("/buy", methods=["GET", "POST"])
@login_required
def buy():
"""Buy shares of stock."""
if request.method == "POST":
if not request.form.get("search"):
return apology("must provide sumbol")
if not request.form.get("number"):
return apology("must provide number of shares to buy")
if float(request.form.get("number")) <= 0:
return apology("number of shares to buy must be a possitive number")
quote = lookup(request.form.get("search"))
if not quote:
return apology("must provide existing company symbol")
cash = db.execute("SELECT cash FROM users WHERE id= :id", \
id=session["user_id"])
if quote["price"] * float(request.form.get("number")) > cash[0]["cash"]:
return apology("not enough cash to buy ordered number of sheres")
price= lookup(request.form.get("search"))
db.execute("INSERT INTO history(user_id, name, symbol, shares, price, total) VALUES(:user_id, :name, :symbol, :shares, :price, :total)", \
user_id= session["user_id"], \
name= price["name"], \
symbol= request.form.get("search"), \
shares= request.form.get("number"), \
price= price["price"], \
total= (float(request.form.get("number")) * float(price["price"])))
db.execute("UPDATE users SET cash = cash - :total WHERE id= :id", \
total= (float(request.form.get("number")) * float(price["price"])), id= session["user_id"])
**user_portfolio= db.execute("SELECT * FROM portfolio WHERE user_id= :id, symbol= :search", \
id= session["user_id"], \
search= request.form.get("search"))
if user_portfolio == None:
db.execute("INSERT INTO portfolio(user_id, name, symbol, shares) VALUES(:user_id, :name, :symbol, :shares)", \
user_id= session["user_id"], \
name= price["name"], \
symbol= request.form.get("search"), \
shares= request.form.get("number"))
else:
db.execute("UPDATE portfolio SET shares=shares + :number WHERE user_id= :id, symbol= :symbol", \
number=request.form.get("number"), \
id=session["user_id"], \
symbol= request.form.get("search"))
return render_template("buy.html")**
