rspec users - Dec 2008 - Problem when testing controllers

I'm having troubles to test methods on controllers, specially this method:
  def update
    @property = @user.properties.find(params[:id])

    if params[:property][:owner_id].blank?
      @owner = Owner.create_from_user(@user)
      @property.owner = @owner
    end

    if @property.update_attributes(params[:property])
      flash[:notice] = 'Imóvel atualizado com sucesso.'
      redirect_to user_property_path(@user)
    else
      render :action => "edit"
    end
  end

This method is pretty standard, except for the line  ==>  if
params[:property][:owner_id].blank?

In my spec file I try this:

      it "should expose the requested property as @property" do
        @property = mock_model(Property, :owner=>:owner, :owner= =>:owner,
:update_attributes => true)
        Property.stub!(:find).and_return(@property)
        Owner.stub!(:create_from_user)

        put :update, :id => "1"
        assigns(:property).should equal(@property)
      end

But get this error:
The error occurred while evaluating nil.[]

The problem is params and I don't know how is the best way to simulete
params hash ...

Anyone can help?

Thanks.

params hash ...
Hi, you need to pass the param in the put:

put :update, :id => "11", :property => {:owner_id =>
"123"}

and when you want to check for the blank one, you just have to pass in
an empty property hash:

put :update, :id => "11", :property => {}

This way params[:property][:owner_id] will return nil.

Thanks, now it's looks obivious. :D
