assigns is for controller and view specs, not model specs. What is it
you''re trying to specify here?

assigns(:message).should eq(@message)

assign(:message, stub("Message", :text => "Hello
world!"))

Hmm, so ''assign'' to assign a variable and
''assigns'' to read an
assigned variable?
We need to update the RSpec 2 wiki or somewhere with all these API
changes so it is clear to everyone.

There''s already info about assign(key, val) on the rspec-rails readme:
http://github.com/rspec/rspec-rails. I''ll add something about
assigns(:key) as well.

Keep in mind that assign(k,v) is used in view specs to provide data to the view,
whereas assigns(key) is used in controller specs to express expectations about
what the controller does.

As for the wiki, let''s hold off on that for now. There is currently
insufficient  documentation in too many places, and the wiki has, at times,
caused more confusion than benefit. I''ve got a few thoughts rolling
around about how to best address this, and I''ll follow up on that in a
separate thread in the next couple of days.

Cheers,
David

Hi David,

Sounds great! Looking forward to more documentation :)
I have now gone through all the examples in the RSpec book and got
them working with the latest version of RSpec 2 and Rails 3 beta4.
I only have one loose end:

shared_examples_for "a template that renders the messages/form
partial" do
  it "renders the messages/form partial" do
    template.should_receive(:render).with(
      :partial => "form",
      :locals => { :message => assigns[:message] }
    )
    render
  end
end

undefined local variable or method `template'' for
#<RSpec::Core::ExampleGroup::Nested_8:0x00000100e019a0>

Changing template to _view as you instructed previously (I think)

    _view.should_receive(:render).with(
      :partial => "form",
      :locals => { :message => assigns[:message] }
    )



 #<ActionView::Base:0x00000100e98c88> received :render with unexpected
arguments
      expected: ({:partial=>"form",
:locals=>{:message=>nil}})
           got: ({:template=>"messages/edit.html.erb"}, {})

But this is my edit.html

<%= render "form", :message => @message %>

So _view only contains info on the view. How do I get info on the
templates called as part of the rendering process?

See the bit on View Specs on

Thanks! Just what I needed :)

shared_examples_for "a template that renders the messages/form
partial" do
  it "renders the messages/form partial" do
    view.should_receive(:_render_partial).
      with(hash_including(:partial => "form"))
    render
  end
end

# new.html.erb

<%= render "sidebar", :recent_messages => @recent_messages %>
<%= render "form", :message => @message %>


7) messages/new.html.erb renders the messages/form partial
    Failure/Error: Unable to find matching line from backtrace
    #<ActionView::Base:0x000001014fbc88> received :_render_partial
with unexpected arguments
      expected: (hash_including(:partial=>"form"))
           got:
({:partial=>"sidebar", :locals=>{:recent_messages=>[]}})


So what to do if I call multiple partials from my view?

view.stub(:_render_partial) before view.should_receive(:_render_partial)

Thanks again David :) Pure magic to me, I don''t really understand how/
why that makes it work. But it does!
