When I browse to artist_new_path I do not see the fields from the user
table (in this example: city). Why is this?
class User < ActiveRecord::Base
has_one :artist
end
-------------
class Artist < ActiveRecord::Base
belongs_to :user
has_many :medias
validates_presence_of :band_name
accepts_nested_attributes_for :user, :reject_if => lambda { |a|
a[:user].blank? }, :allow_destroy => true
end
-------------
/app/views/artists/new
<%= form_for(@artist) do |f| %>
<ul>
<li class="clearfix">
<%= f.label :band_name %>
<%= f.text_field :band_name %>
</li>
<li>
<% f.fields_for :user do |builder| %>
<%= builder.label :city %>
<%= builder.text_field :city %>
<% end %>
</li>
</ul>
<% end %>

> > class Artist < ActiveRecord::Base > belongs_to :user >> accepts_nested_attributes_for :userthis is backwards, artist is nested inside users but you want artist to accept nested attributes of users. It only works the when you are accepting attributes for the child model from inside the parent. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Ok... someone suggested to use virtual attributes instead. Is this the
right way to go?
Basically a registered user can sign up as an artist.
Artist model has the following fields: id, user_id, band_name
User model has: id, name, city_id, genre_id
In the artist registration form:
<%= form_for(@artist) do |f| %>
<ul>
<li class="clearfix">
<%= f.label :band_name %>
<%= f.text_field :band_name %>
</li>
<li class="clearfix">
<%= f.label :city_id %>
<%= f.grouped_collection_select(:city_id,
Country.find(:all), :cities, :name, :id, :name, { :prompt => ''Select
a
city'' }) %>
</li>
<li class="clearfix">
<%= f.label :genre_id %>
<%= f.collection_select :genre_id, Genre.all, :id, :name,
{ :prompt => ''Select a genre'' } %>
</li>
</ul>
<% end %>
In my artist model, I created virtual attributes:
class Artist < ActiveRecord::Base
belongs_to :user
has_many :medias
validates_presence_of :band_name
attr_accessible :band_name, :city_id, :genre_id
# Virtual attribute. Needed when user wants to register as an artist
def city_id
end
# Virtual attribute. Needed when user wants to register as an artist
def genre_id
end
def after_create
# Update the user fields: city_id and genre_id
self.user.update_attributes(
:city_id => self.city_id,
:genre_id => self.genre_id
)
end
end
However, when I submit the form, I get:
ActiveRecord::UnknownAttributeError in ArtistsController#create
unknown attribute: city_id
The error occurs in the artist controller def create method. The first
line: @artist = Artist.new(params[:artist])
Am I doing this right? What is wrong?
