[rspec-users] possible to stub params hash ?

I tried to stub the params method of the Controller because
I got the error " You have a nil object when you didn't expect it!"
for the access to params[:pl_planning]["item_model_version_id"] 
in the update action.

I thought, that the stubbing is not working because of the following error:
"undefined method `scope=' for #<Searchlogic::Cache::PlPlanningSearch:0x6aa14cc>".

But now I found out, that this error has another reason.
The put :update does not call the update action, it calls the index action.
I will post another email for that problem to the user group.

I added one line in my controller to extend the params hash. But now I get errors
in my controller spec.


 def update
 @pl_planning = PlPlanning.find(params[:id])

 # the item model version (select box) depends on other select boxes and can be empty
 # then it is not in the params hash and the attribute would not be updated and validated
--> params[:pl_planning]["item_model_version_id"] ||= ""

 # update planning attributes
 @pl_planning.attributes = params[:pl_planning] 

Controller Spec error:

You have a nil object when you didn't expect it!
You might have expected an i nstance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

What do I have to add in my spec for that ?

I tried:

 params = {"pl_planning" => {}}

But then I get the following error:

undefined method `scope=' for #<Searchlogic::Cache::PlPlanningSearch:0x6aa14cc>
Usually you are will fare better if you pass the params directly in:
get :foo, :param1 => "something"
Why are you stubbing params?

Thanks in advance
