The code I've written for the parameter checks all works fine, and on clicking the buy button everything seems to work... but then nothing gets added to my database! I've combed through the SQL query again and again. I'm so sure the syntax is correct, and I'm not getting any error messages... Can anyone spot where I'm going wrong?

# record purchase
purchase = db.execute("INSERT INTO transactions (user_id, symbol, name, shares, price, total) VALUES (:user_id, :symbol, :name, :shares, :price, :total)",
    user_id=session["user_id"], symbol=result["symbol"], name=result["name"], shares="shares", price=result["price"], total="total")

A lengthier snippet of my code is here: https://gist.github.com/4b64b3d28aa19568d4bfbb0039cc47d8

Reset to default

Assuming transactions.total is a numeric field, this total="total" would be problematic since "total" is a string literal.

  • That's precisely what it was... also, I had set the date_time field to Not Null without assigning its default value... Wow, always such a facepalm with hindsight... Thank you so, so much for your help.
