Hello list, I think I have a rails related RSpec problem with a mock going out of scope on a recursive call to a model.
The code is at: http://pastie.textmate.org/79821 if you want to see it highlighted. I have pasted it below as well. Basically, I have an acts_as_nested_set model called "Node", which works fine. I have a function which finds the language name of the node instance. If the language is nil for the node instance being queried, it then recursively calles language_name on it's parent until one of them has the language. Then this gets returned. When I do this with a fixture, it works fine. Ie, a Database call can be made to a language table and I get the language name. In the code attached it has a langauge instance being mocked. I get the same result if I mock Language.should_receive(:find)... It SEEMS like the Mock is going out of scope on the recursive call to parent. The direct spec to the parent to get language name works fine. Any ideas? (the code below is slimmed down to the code needed to run the spec. Regards Mikel CODE:: class Node < ActiveRecord::Base belongs_to :language acts_as_nested_set :scope => :root_id def language_name self.root? ? language.name : parent.language_name end end describe Node, "instance" do fixtures :nodes before(:each) do @language = mock_model(Language, :name => "Japanese") @node = Node.create!(:language => @language) @section1 = Node.create!() @chapter1 = Node.create!() end it "should return it's own language if it is root" do # Passes @language.should_receive(:name).exactly(:once).and_return("Japanese") @node.language_name.should == "Japanese" end it "should return it's parent's language if it is a child" do # Fails (message below) @section1.move_to_child_of(@node) @chapter1.move_to_child_of(@section1) @language.should_receive(:name).exactly(:once).and_return("Japanese") @section1.language_name.should == "Japanese" @language.should_receive(:name).exactly(:once).and_return("Japanese") @chapter1.language_name.should == "Japanese" end end SPEC ERROR:: NoMethodError in 'Node instance should return it's parent's language if it is a child' You have a nil object when you didn't expect it!
