[rspec-users] Extending assigns in controller specs?

[Scott Taylor]

One method would be to:

1. figure out the class
2. reopen the class,
3. alias the method,
4. use your method if multiple keys are given, use the old aliased  
method if not.

Don't know if assigns might have some metaclass trickery, though.   
Post what you find.  I'd be interested.

As for spec'ing it out, first:

require File.dirname(__FILE__) + "/..."

class MyController < ActionController
   def single_var
     @var = "var"
   end

   def multi_var
     @var1 = 1
     @var2 = 2
   end
end

describe "MyController's single_var" do
   controller_name :my_controller

   setup do
     get :single_var
   end

   it "should assign one variable" do
     assign[:var].should == "var"
   end
end

describe "MyController's multi_var" do

   ...

   it "should assign multi variables" do
     assign[:var1, :var2].should == [1, 2]
   end
end


Obviously you can use more descriptive names than I have here.  But I  
hope you can see where I'm going with this.
