Ruby on Rails: create records for multiple models with one form and one submit
- by notblakeshelton
I have a 3 models: quote, customer, and item. Each quote has one customer and one item. I would like to create a new quote, a new customer, and a new item in their respective tables when I press the submit button. I have looked at other questions and railscasts and either they don't work for my situation or I don't know how to implement them. I also want my index page to be the page where I can create everything.
quote.rb
class Quote < ActiveRecord::Base
attr_accessible :quote_number
has_one :customer
has_one :item
end
customer.rb
class Customer < ActiveRecord::Base
#unsure of what to put here
#a customer can have multiple quotes, so would i use:
has_many :quotes #<----?
end
item.rb
class Item < ActiveRecord::Base
#also unsure about this
#each item can also be in multiple quotes
quotes_controller.rb
class QuotesController < ApplicationController
def index
@quote = Quote.new
@customer = Customer.new
@item = item.new
end
def create
@quote = Quote.new(params[:quote])
@quote.save
@customer = Customer.new(params[:customer])
@customer.save
@item = Item.new(params[:item])
@item.save
end
end
items_controller.rb
class ItemsController < ApplicationController
def index
end
def new
@item = Item.new
end
def create
@item = Item.new(params[:item])
@item.save
end
end
customers_controller.rb
class CustomersController < ApplicationController
def index
end
def new
@customer = Customer.new
end
def create
@customer = Customer.new(params[:customer])
@customer.save
end
end
quotes/index.html.erb
<%= form_for @quote do |f| %>
<%= f.fields_for @customer do |builder| %>
<%= label_tag :firstname %>
<%= builder.text_field :firstname %>
<%= label_tag :lastname %>
<%= builder.text_field :lastname %>
<% end %>
<%= f.fields_for @item do |builder| %>
<%= label_tag :name %>
<%= builder.text_field :name %>
<%= label_tag :description %>
<%= builder.text_field :description %>
<% end %>
<%= label_tag :quote_number %>
<%= f.text_field :quote_number %>
<%= f.submit %>
<% end %>
When I try submitting that I get an error:
Can't mass-assign protected attributes: item, customer
So to try and fix it I updated the attr_accessible in quote.rb to include :item, :customer but then I get this error:
Item(#) expected, got ActiveSupport::HashWithIndifferentAccess(#)
Any help would be greatly appreciated.
