I've searched and searched, and just can't find an answer on the list or
elsewhere. Forgive me if I'm missing something...
I've got the following bits of code:
### app/controllers/widget_layouts_controller.rb:
class WidgetLayoutsController < ApplicationController
def new
@widget = Widget.find(params[:widget_id])
@widget_layout = WidgetLayout.new
end
end
### app/models/widget_layout.rb:
class WidgetLayout < ActiveRecord::Base
belongs_to :widget
end
### app/models/widget.rb:
class Widget < ActiveRecord::Base
has_one :widget_layout, :dependent => :destroy
end
### From config/routes.rb:
resources :widgets do
resource :widget_layout
end
### spec/widget_layouts/new.html_spec.rb:
require "spec_helper"
describe "widget_layouts/new.html.erb" do
it "should render the new widget layout form" do
widget = stub_model(Widget)
assign(params[:widget_id], widget)
render
rendered.should have_selector("form", :method => "post", :action =>
widget_widget_layout_path(widget))
end
end
### app/views/widget_layouts/new.html.erb
<%= form_for @widget_layout, :url => widget_widget_layout_path(@widget) do |f|
%>
<%= f.submit "Submit Widget Layout Information" %>
<% end %>
Here's the error I get when running that spec:
widget_layouts/new.html.erb
should render the new widget layout form (FAILED - 1)
Failures:
1) widget_layouts/new.html.erb should render the new widget layout form
Failure/Error: render
No route matches {:controller=>"widget_layouts", :action=>"destroy"}

I believe this is because params[:widget_id] isn't assigned when I'm rendering
new.html.erb. I know that's an improper usage of #assign up there, but this is
what I was trying to rectify (obviously incorrectly...) I'm confused as to how
to mock/stub and specify parent resource(s) when trying to test views of
children resources. What should I be doing differently?
Also--not an RSpec question--that's the only way I can get that #form_for call
to work correctly. Everywhere I looked, it seemed that I could simply use:
form_for [...@widget, @widget_layout] do |f| %>
but alas, all I get is the following errors:
_______________________

Any chance I might get some help on this one while I'm at it? :)
