I’m creating a practice app on RoR, but i’ve run into this problem and
I’m not sure how to proceed. Basically, its a stock picker, and there
are Portfolios, Stocks, and Holdings. Holdings belong to both
Portfolios and a particular Stock.
In my “create holding” page, i’m allowing the user to provide a Stock
symbol (a string column in the stock table) and a quanity. However,
for obvious reasons this doesnt work as when the form is submitted,
@holding = Holding.new(params[:holding])
Expects the value of “stock” that is passed in to be an actual Stock
object, not a string representing the symbol for that stock.
How exactly should I get around this without converting the Stock
field to a dropdown?
