Having issues saving line items to the DB

Hello everyone, I’m fairly new to Rails (writing my first real app) and
brand new to this mailing list.

I’ve got a rails/sql error I just can’t seem to solve. It’s probably
really simple, but I’m been googling and reading for a day and have made
zero progress on it. Hopefully someone on this list can shine some light
on my problem, or point me in the right direction.

has_many :quotes

has_many :line_items

belongs_to :quote

@project = Project.new(params[:project])


if params[:line_item1][‘quantity_id’] != ‘’
@line_items << LineItem.new(params[:line_item1])

if params[:line_item2][‘quantity_id’] != ‘’
@line_items << LineItem.new(params[:line_item2])

@[email protected]
@quote.line_items << @line_items



I can get the project and quote models to save to the DB just fine, but
when I try to add the line_items array to the quote object (so they are
saved as child records) I get a nasty SQL error.

Rails appears to be trying to save the internal object reference to the
DB, instead of the attributes. I can’t figure out why, or how to fix it.

@quote.line_items << @line_items

I dont think you can append an array to an association like that. Try
this instead:

@line_items.each do |li|
@quote << li
