Can’t get this Rspec test to pass
Hello,
I’m completely new to Rspec testing and I’m finding it very difficult to mock specific objects.
In this test, I have a before block setup as such:
before do
setup_controller_for_warden
controller.session[:operation_id] = 1
@operator = Factory :operator
sign_in :operator, @operator
@persist_herd = Herd.new
@persist_herd.operation_id = 1;
@persist_herd.herd_name = 'Persisted Herd (herd_rations_controller_spec)'
@persist_herd.save!
end
describe "GET new" do
it "assigns a new herd_ration as @herd_ration" do
HerdRation.stub(:new){ mock_herd_ration }
Herd.stub(:find).with(1) { @persistant_herd }
get :new, :herd_id => 1
assigns(:herd_ration).should be(mock_herd_ration)
response.should be_success
end
end
and here's my controller method:
def new
@herd_ration = HerdRation.new
@herd = Herd.find(params[:herd_id])
if @herd
respond_with(@herd_rations, :layout=> !request.xhr?)
else
redirect_to(root_url, :notice => 'No herd selected for ration.')
end
end
Here’s the catch - we have this groovy little plugin that globally enforces a model scope via a session id, in this case: session[:operation_id].
Here’s the code for the plugin:
module ApplicationScopeManager
mattr_accessor :global_scope
@@global_scope = []
mattr_accessor :local_scope
@@local_scope = {}
def self.included(base)
base.send :extend, ClassMethods
end
def self.setup
yield self
end
module ClassMethods
def method_missing(name, *args, &block)
return acts_as_scope_manager($1, args) if name.to_s =~ /^acts_as_scope_manager_for_(.*)/
return honors_scope_of($1, args) if name.to_s =~ /^honors_scope_of_(.*)/
return current_scope_for($1) if name.to_s =~ /^current_scope_for_(.*)/
super
end
def current_scope_for(scope)
Thread.current[scope.to_sym]
end
def acts_as_scope_manager(scope, *args)
options = args[0].extract_options! if args
send :include, InstanceMethods
set_global_scope(scope,options[:with_global_scope]) if options[:with_global_scope]
send :before_filter, "set_scope_for_#{scope}".to_sym if self.ancestors.include? ActionController::Base
send :default_scope, where(scope.to_sym => send("current_scope_for_#{scope}".to_sym)[:finder_scope]).create_with(scope.to_sym =>
send("current_scope_for_#{scope}".to_sym)[:creator_scope]) if (self.ancestors.include? ActiveRecord::Base) && Thread.current[scope.to_sym]
end
alias honors_scope_of acts_as_scope_manager
private
def set_global_scope(scope, *args)
Thread.current[scope.to_sym] = {:global_scope => args}
end
end
module InstanceMethods
def method_missing(name, *args, &block)
return set_scope_for($1, args) if name.to_s =~ /^set_scope_for_(.*)/
super
end
private
def set_scope_for(scope, *args)
if session[scope].class == Array
application_scope = {:finder_scope => session[scope], :creator_scope => nil }
else
application_scope = {:finder_scope => [session[scope]], :creator_scope => session[scope] }
end
application_scope[:finder_scope] = application_scope[:finder_scope] + Thread.current[scope.to_sym][:global_scope] if Thread.current[scope.to_sym][:global_scope]
Thread.current[scope.to_sym] = application_scope
end
end
end
This plugin enforces any model that calls the honors_scope_of_operation_id to include a lookup of the session[:operation_id] in all database calls. For instance if I do a Model.find(params[:id]) it will automatically add a WHERE “field_name”.“operation_id” = to the where clause. The problem I’m having is that I can’t seem to mock the session[:operation_id] in my Rspec tests. I thought setting it this way controller.session[:operation_id] = 1 in the before block would have been sufficient.
Any ideas?
