[rspec-users] "assign" to variable in view seems to give nil object

Hello,

I am doing my first steps with rspec and did the following
observation.
I wanted to write a spec for a standard scaffold index view.

Now, my view spec looks like:

describe "/a_details/index.html.erb" do

  it "should list all the details of as in an unordered list" do
    assign[:a_details] = [''test'']

    render ''/a_details/index.html.erb''

    response.should have_tag("ul") do
      with_tag("li") do
        with_tag("div", "Name")
        with_tag("div", "Details")
      end
    end
  end
end

Can someone show me a direction and/or has a solution to this ?

When I run this I get:


1)
ActionView::TemplateError in ''/a_details/index.html.erb should list
all the details of shoes in an unordered list''
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each

This looks like Rails-2/RSpec-1. If that''s correct, then you want to
use "assigns" instead of "assign".

HTH,

Thanks, David.
You are right, there could be a clash of versions.

Now, "assigns" gives:

index_spec.rb:6: undefined local variable or method `assigns'' for
Spec::Rails::Example::ViewExampleGroup::Subclass_1:Class (NameError)
	from /opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/lib/spec/example/
example_group_methods.rb:183:in `module_eval''
	from /opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/lib/spec/example/
example_group_methods.rb:183:in `subclass''
	from /opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/lib/spec/example/
example_group_methods.rb:55:in `describe''
	from /opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/lib/spec/example/
example_group_factory.rb:31:in `create_example_group''

Maybe I shall start with another clean rails project?

Thanks for your help,
Patrick
