Nested resource view spec seems to be referring to a non-existent route

Testing RSpec
1

Hi all,

In a view spec for a nested resource, do I need to instantiate/stub
the parent resource before I stub the nested resource?

I am asking this because all my view specs are failing for a new
nested resource I have introduced in my application. The nested
resource works as expected
when I manually test it though :frowning:

Here’s how my edit view spec looks like.

----------- “./spec/views/sub_categories/edit.html.erb_spec.rb” -
start --------
require ‘spec_helper’

describe “sub_categories/edit.html.erb” do
before(:each) do

@sub_category = assign(:sub_category, stub_model(SubCategory,
  :name => 'International interest rates',
  :description => 'Comprehensive rates covering Australia, NZ,

Malaysia and Singapore’,
:category_id => 3,
:created_by => 1,
:updated_by => 1
))
end

it “renders the edit sub category form” do
render

# Run the generator again with the --webrat flag if you want to

use webrat matchers
assert_select “form”, :action =>
category_sub_categories(@sub_category), :method => “post” do
assert_select “input#sub_category_name”, :name =>
“sub_category[name]”
assert_select “textarea#sub_category_description”, :name =>
“sub_category[description]”
end
end
end
----------- “./spec/views/sub_categories/edit.html.erb_spec.rb” - end

Here’s an extract of the failure:
----------- extract start -------------------------

  1. sub_categories/edit.html.erb renders the edit sub category form
    Failure/Error: render
    ActionView::Template::Error:
    undefined method `sub_category_path’ for #<#<Class:
    0x0000010127d2b8>:0x000001016e2380>

    ./app/views/sub_categories/_form.html.erb:1:in

_app_views_sub_categories__form_html_erb__4092631658606598204_2155519360' # ./app/views/sub_categories/edit.html.erb:3:in_app_views_sub_categories_edit_html_erb___3853358586184509671_2155544160’
# ./spec/views/sub_categories/edit.html.erb_spec.rb:15:in `block
(2 levels) in <top (required)>’

----------- extract end -------------------------

Here’s what my form partial looks like

----- app/views/sub_categories/_form.html.erb start

<%= form_for [@category, @sub_category] do |f| %>
<% if @sub_category.errors.any? %>


<%= pluralize(@sub_category.errors.count, “error”) %>
prohibited this sub_category from being saved:

  <ul>
  <% @sub_category.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
</div>

<% end %>

<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :description %>
<%= f.text_area :description %>
<%= f.submit %>
<% end %>

----- app/views/sub_categories/_form.html.erb end

Here’s what I see when I run ‘rake routes’:

------- routes start ---------------------------

category_sub_categories GET /categories/:category_id/
sub_categories(.:format)
{:action=>“index”, :controller=>“sub_categories”}
POST /categories/:category_id/
sub_categories(.:format)
{:action=>“create”, :controller=>“sub_categories”}
new_category_sub_category GET /categories/:category_id/

PUT /
categories/:id(.:format)
{:action=>“update”, :controller=>“categories”}
DELETE /
categories/:id(.:format)
{:action=>“destroy”, :controller=>“categories”}
root /

------- routes end ---------------------------

The form partial has been properly fitted with the parent resource
and the nested resource (ie. “form_for [@category, @sub_category]” ).

It seems that it’s calling a route, sub_category_path which I have
never specified.
The error comes up when an edit/create form is to be created where a
form partial is called.

I am really puzzled on why this is happening and have consulted the
search results I had via google for ‘nested resources with rspec’ ,
‘Rails in Action 3’ by Yehuda K., and the Rspec book :frowning:

If anyone knows what I am missing, I would love to hear your thoughts.

thank you :slight_smile:
