rendering-collections-lab's Introduction

Rendering Collections Lab

Objectives

  1. Use the collection keyword with partials
  2. Pass a collection to the render method
  3. Handle empty collections

Overview

Let's go back to our store domain. We had an admin portion of the site where admins could check on their orders and invoices. We've changed it slightly so that, rather than static pages with stubs for orders, we've seeded the database with actual order data. Let's refactor the admin portion of the store to use partials and render collections.

Instructions

We've provided a seed file so you can have some data to play around with –– run rake db:migrate and rake db:seed to seed the database.

  1. Refactor the invoices/index.html.erb view to render a collection of partials with _invoice.html.erb.
  2. Refactor the orders/index.html.erb view to render a collection of partials with _order.html.erb.

the tests for orders have the same names as the tests for invoices.

Wrong directions

Hello, Instructions say to refractor the two files that are not available as opposed to telling the student to create and extract. A bit confusing

weird error

worked through this with Adam this morning. here's the error

Failures:

  1. orders_index_view renders the order partial
    Failure/Error: <% @orders.each do |order| %>
 ActionView::Template::Error:
   undefined method `each' for #<Order:0x007fa34d2c1648>
 # ./app/views/orders/index.html.erb:9:in `_app_views_orders_index_html_erb__47327540943352512_70169675518120'
 # ./spec/views/orders_index_view_spec.rb:29:in `block (2 levels) in <top (required)>'
 # ------------------
 # --- Caused by: ---
 # NoMethodError:
 #   undefined method `each' for #<Order:0x007fa34d2c1648>
 #   ./app/views/orders/index.html.erb:9:in `_app_views_orders_index_html_erb__47327540943352512_70169675518120'

the controller is passing in @orders as @orders = Order.all but adam noticed that the tests are passing in Order.first looks like from line 27 in spec/views/orders_index_view_spec.rb

and i believe the same thing was happening with the first test too from line 28 of spec/views/invoices_index_view_spec.rb
