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"
class Godfather < ActiveRecord::Base
belongs_to :zz_user_id, :class_name => "User"
belongs_to :user_godfather_id, :class_name => "User"
Now my question is about how to manage the edit form of this nested
Here is how my form looks like at the moment (using the
<%= nested_form_for @user do |f| %>
<%= f.fields_for :godfathers do |godfather_form| %>
# Here I have an ID text field but what I want
# 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
<% end %>
<%= f.link_to_add "Add a godfather", :godfathers %>
<%= 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?
