Hey guys & ladies!
I've got the following relationship which i'm trying to get
accepts_nested_attributes to work with. But when i submit my form, it
looks as if its expecting a Company object, rather than an array of
companies. which really doesn't make sense considering its a
has_many :relationship.
So what i'm after, is a way to
accept_nested_attributes_for :companies, so when my users sign up to
the website, they can also create a company.
-------------- user.rb
class User < ActiveRecord::Base
has_many :company_users
has_many :companies, :through => :company_users
accepts_nested_attributes_for :companies
end
-------------- company.rb
class Company < ActiveRecord::Base
has_many :company_users
has_many :users, :through => :company_users
end
-------------- company_user.rb
class CompanyUser < ActiveRecord::Base
belongs_to :user
belongs_to :company
end
-------------- My form
<% form_for :user, :url => users_path do |f| -%>
<p><%= label_tag 'First name' %>
<%= f.text_field :firstname %></p>
<p><%= label_tag 'Surname' %>
<%= f.text_field :surname %></p>
<p><%= label_tag 'email' %>
<%= f.text_field :email %></p>
<p><%= label_tag 'password' %>
<%= f.password_field :password %></p>
<p><%= label_tag 'password_confirmation', 'Confirm Password' %>
<%= f.password_field :password_confirmation %></p>
<h2>Company Information</h2>
<% f.fields_for :companies do |company| %>
<%= render 'companies/fields', :f => company %>
<% end %>
<p class="submit"><%= submit_tag 'Sign up' %></p>
<% end -%>
-------------- The error
ActiveRecord::AssociationTypeMismatch in UsersController#create
Company(#2180266380) expected, got Array(#2148226700)
