Does << create a new record?

Rails
1

Search engine don’t index << so it’s hard to find info about it.

Let’s say I have:

order = order.create
item = Item.new

Will order.items << item create a new entry for the item in DB or not?
I’m having issues.

Yes, it will save the item (assuming Order has many Items, Item
belongs to Order). If it doesn’t, something else is wrong (like the
item not being valid).

Nice catch, one of my items was not valid.

For the future:

go to: “http://api.rubyonrails.org/”
use your browser’s find to search for: “<<”
