Associated models in Rails?
- by dannymcc
Hi Everyone,
In my rails application I have two models called Kases and Notes. They work in the same way comments do with blog posts, I.e. each Kase entry can have multiple notes attached to it.
I have got everything working, but for some reason I cannot get the destroy link to work for the Notes. I think I am overlooking something that is different with associated models to standard models.
Notes Controller
class NotesController < ApplicationController
# POST /notes
# POST /notes.xml
def create
@kase = Kase.find(params[:kase_id])
@note = @kase.notes.create!(params[:note])
respond_to do |format|
format.html { redirect_to @kase }
format.js
end
end
end
Kase Model
class Kase < ActiveRecord::Base
validates_presence_of :jobno
has_many :notes
Note Model
class Note < ActiveRecord::Base
belongs_to :kase
end
In the Kase show view I call a partial within /notes called _notes.html.erb:
Kase Show View
<div id="notes">
<h2>Notes</h2>
<%= render :partial => @kase.notes %>
<% form_for [@kase, Note.new] do |f| %>
<p>
<h3>Add a new note</h3>
<%= f.text_field :body %><%= f.submit "Add Note" %>
</p>
<% end %>
</div>
/notes/_note.html.erb
<% div_for note do %>
<div id="sub-notes">
<p>
<%= h(note.body) %><br />
<span style="font-size:smaller">Created <%= time_ago_in_words(note.created_at) %> ago on <%= note.created_at %></span>
</p>
<%= link_to "Remove Note", kase_path(@kase), :confirm => 'Are you sure?', :method => :delete, :class => 'important' %>
</div>
<% end %>
As you can see, I have a Remove Note destroy link, but that destroys the entire Kase the note is associated with. How do I make the destroy link remove only the note?
<%= link_to "Remove Note", kase_path(@kase), :confirm => 'Are you sure?', :method => :delete, :class => 'important' %>
Any help would, as always, be greatly appreciated!
Thanks,
Danny
