Hello, I am trying to get going with development of view components with Rspec2 and Rails3. However, I make the following observation, and I don''t understand what is going on, and how to fix this. In my spec I define: describe "main/index.html.erb" do it "displays a photo url in products partial" do assign(:designs, [stub_model(Design, :name => "test", :photo => "photo_url")]) render rendered.should contain("photo_url") end end When I run: rspec spec/view/main_spec.rb I get this error: 1) main/index.html.erb displays a photo url in products partial Failure/Error: render ActionView::Template::Error: undefined method `photo'' for nil:NilClass # ./app/views/main/_design.html.erb:3:in `_app_views_main__design_html_erb__2937334847274155273_2170841960__1566661024965846011'' # ./app/views/main/index.html.erb:25:in `_app_views_main_index_html_erb__837234277009287876_2170861440__898201527838028543'' # ./spec/views/main_spec.rb:7:in `block (2 levels) in <top (required)>'' However, if I only ''access'' a local photo object in my partial everything passes. This is: in _design.html.erb: <%= design %> ---> PASS <%= design.photo %> ---> FAIL In my view I call my partial as follows: main.html.erb <%= render "design", :locals => { :designs => @designs } %> What am I missing. Thank you for your help!
The problem is probably due to assignment of the photo attachment. I got a unit test working with: test "the partial" do design = Design.new :photo => File.new(Rails.root + "test/ fixtures/images/rails.png") p design.photo(:medium) render :partial => "main/design", :locals => { :design => design }, :layout => false assert_select "div.product-img a.product-link img[src^=''/designs/ photos//medium_rails.png'']" end On Jan 16, 10:46?am, poseid <mulder.patr... at gmail.com> wrote:> Hello, > > I am trying to get going with development of view components with > Rspec2 and Rails3. > However, I make the following observation, and I don''t understand what > is going on, and how to fix this. > > In my spec I define: > > ? describe "main/index.html.erb" do > ? ? it "displays a photo url in products partial" do > ? ? ? assign(:designs, [stub_model(Design, :name => "test", :photo => > "photo_url")]) > > ? ? ? render > ? ? ? rendered.should contain("photo_url") > ? ? end > ? end > > When I run: > > ? ? rspec spec/view/main_spec.rb > > I get this error: > > ? ? 1) main/index.html.erb displays a photo url in products partial > ? ? ? ?Failure/Error: render > ? ? ? ?ActionView::Template::Error: > ? ? ? ? ?undefined method `photo'' for nil:NilClass > ? ? ? ?# ./app/views/main/_design.html.erb:3:in > `_app_views_main__design_html_erb__2937334847274155273_2170841960__1566661024965846011'' > ? ? ? ?# ./app/views/main/index.html.erb:25:in > `_app_views_main_index_html_erb__837234277009287876_2170861440__898201527838028543'' > ? ? ? ?# ./spec/views/main_spec.rb:7:in `block (2 levels) in <top > (required)>'' > > However, if I only ''access'' a local photo object in my partial > everything passes.

[rspec-users] Rspec2 partial view gives nil:NilClass. Why?
