Hi,
Basically I have two models: User and Godfather. The godfather table has three columns:
- user_id (FK --> User) - user_godfather_id (FK --> User) - description (text)
Inside each model class, I am adding the following associations:
class User < ActiveRecord::Base
has_many :godfathers # for user_id has_many :godfathers, :foreign_key => "user_godfather_id", :class_name => "Godfather"
accepts_nested_attributes_for :godfathers end
class Godfather < ActiveRecord::Base belongs_to :zz_user_id, :class_name => "User" belongs_to :user_godfather_id, :class_name => "User" end
Now my question is about how to manage the edit form of this nested attribute relationships. Here is how my form looks like at the moment (using the nested_form_for gem):
<%= nested_form_for @user do |f| %> <%= f.fields_for :godfathers do |godfather_form| %> # Here I have an ID text field but what I want instead is # to provide a username for this godfather. <%= godfather_form.label :user_godfather_id %> <%= godfather_form.text_field :user_godfather_id %>
<%= godfather_form.label :description %> <%= godfather_form.text_field :description %>
<%= godfather_form.link_to_remove "Remove this godfather" %> <% end %> <%= f.link_to_add "Add a godfather", :godfathers %> <br/><br/> <%= f.submit "Update Godfathers" %>
So as I said in the comments, my goal is to be able to provide a username for the godfather instead of an id. That username is a column in the User table by the way.
Any idea about how I should go about it?
Thanks!
