No route matches when trying to edit - ruby-on-rails

Question

Here's the scoop: I've created a test app that allows users to create ideas and then add "bubbles" to these ideas. Currently, a bubble is just text. I've successfully linked bubbles to ideas. Furthermore, when a user goes to view an idea it lists all of the bubbles attached to that idea. The user can even delete the bubble for a given idea.
My problem lies in editing bubbles. When a user views an idea, he sees the idea's content as well as any bubbles for that idea. As a result, I've set all my bubble controls (editing and deleting) inside the ideas "show" view. My code for editing a bubble for an idea is <%= link_to 'Edit Bubble', edit_idea_bubble_path %>. I ran rake routes to find the correct path for editing bubbles and that is what was listed.
Here's my error: No route matches {:action=>"edit", :controller=>"bubbles"}
In my bubbles controller I have:
def edit
#idea = Idea.find(params[:idea_id])
#bubble = #idea.bubbles.find(params[:id])
end
def update
#idea = Idea.find(params[:idea_id])
#bubble = #idea.bubbles.find(params[:id])
respond_to do |format|
if #bubble.update_attributes(params[:bubble])
format.html { redirect_to(#bubble,
:notice => 'Bubble was successfully updated.') }
format.xml { head :ok }
else
format.html { render :action => "Edit" }
format.xml { render :xml => #bubble.errors,
:status => :unprocessable_entity }
end
end
end
To go a step further, I have the following in my routes.rb file
resources :ideas do
resources :bubbles
end
So far everything seems to function except when I try to edit a bubble.
I'd love some guidance.
Thanks!
Here's my show.html.erb file for Ideas:
<h2>Bubbles</h2>
<% #idea.bubbles.each do |bubble| %>
<p>
<b>Bubble:</b>
<%= bubble.description %>
</p>
<p>
<%= link_to 'Edit Bubble', edit_idea_bubble_path (#idea) %>
</p>
<tb />
<p>
<%= link_to 'Delete Bubble', [bubble.idea, bubble],
:confirm => 'Are you sure you want to delete this bubble?',
:method => :delete %>
</p>
<% end %>
<h2>Add a bubble:</h2>
<%= form_for([#idea, #idea.bubbles.build]) do |f| %>
<div class="field">
<%= f.label :description %><br />
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %> </div><% end %>
Following edit_idea_bubble_path (#idea), here is the edit.html.erb file for Bubbles:
<%= render 'form' %>
<%= link_to 'Back to Ideas', ideas_path %>
And finally, my _form.html.erb file for Bubbles: this is where the problem lies, I believe
<% form_for([#idea, #idea.bubbles.build]) do |f| %>
<%= f.error_messages %>
<div class="field">
<%= f.label :description %><br />
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

Answer 1

First build the route in your show.html.erb file
<%= link_to 'Edit Bubble', edit_idea_bubble_path(#idea, bubble) %>
Then, your controller should have 2 objects for both #idea and #bubble
when action is new
#idea = Idea.find_by_id(:params[:idea_id])
#bubble = #idea.bubbles.build
when action is edit
#idea = Idea.find_by_id(:params[:idea_id])
#bubble = #idea.bubbles.find_by_id(:params[:bubble_id])
In your _form.html.erb
<% form_for([#idea, #bubble]) do |f| %>

Answer 2

You have to provide the idea and the bubble objects:
<%= link_to 'Edit Bubble', edit_idea_bubble_path(#idea,#bubble) %>
Update:
Edit the _form.html.erb file
<% form_for([#idea, #bubble]) do |f| %>
