I'm relatively new to Rails myself, though I've been somewhat
successful with nested model associations in both directions.
Models:
class Person < ActiveRecord::Base
belongs_to :address
accepts_nested_attributes_for :address
end
class Address < ActiveRecord::Base
has_many: persons
accepts_nested_attributes_for :persons
end
Controller:
class PersonsController < ApplicationController
def new
@person = Person.new
@person.address = Address.new
end
def create
@person = Person.new params[:person]
if @person.save
redirect_to :show
else
render :new
end
end
end
class AddressesController < ApplicationController
def new
@address = Address.new
1.times { @address.persons.build } # increase 1 to default number of
people at address
end
def create
@address = Address.new params[:address]
if @address.save
redirect_to :show
else
render :new
end
end
Views:
# persons/new.html.erb
<% form_for @person do |person_fields| %>
<% person_fields.fields_for :address do |address_fields| %>
<%= address_fields.label ... %>
<% end %>
<% end %>
# addresses/new.html.erb
<% form_for @address do |address_fields| %>
<% address_fields.fields_for :persons do |person_fields| %>
<%= person_fields.label ... %>
<% end %>
<% end %>
If you get weird errors such as HashWithIndifferentAccess, try
refreshing your browser, so it pulls in a fresh form.
Hope that helps,
Mike
