Unable to get the update function to pass test

Using the test parameters the Jason Seifer provided in the "What is a Join Table" video, I cannot get the test to pass. Here is the code I am using:

def update
    @status = current_user.statuses.find(params[:id])

    if params[:status] && params[:status].has_key?(:user_id)
    #if status_params && status_params.has_key?(:user_id)
      params[:status].delete(:user_id)
    end

    respond_to do |format|
      if @status.update(status_params)
        format.html { redirect_to @status, notice: 'Status was successfully updated.' }
        format.json { render :show, status: :ok, location: @status } #Original
      else
        format.html { render :edit }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
  end

and the error I am getting:

  1) Error:
StatusesControllerTest#test_should_not_update_status_if_nothing_has_changed:
ActionController::ParameterMissing: param is missing or the value is empty: status
    app/controllers/statuses_controller.rb:81:in `status_params'
    app/controllers/statuses_controller.rb:52:in `block in update'
    app/controllers/statuses_controller.rb:51:in `update'
    test/controllers/statuses_controller_test.rb:83:in `block in <class:StatusesControllerTest>'

14 runs, 32 assertions, 0 failures, 1 errors, 0 skips

Any thoughts would be great appreciated!

A gracious user on Stack Overflow posted this solution:

The problem is in your test case patch :update, id: @status.

Try this:

patch :update, {id: @status.id, status: {user_id: @status.user_id, content: 'MyText'}}

The problem was I was not passing the status through to the controller. This solution passes the same content as was already there; effectively replicating a condition where no change was made. Success!
