Join Table Woes

Question

Another battle with version differences in the Ruby on Rails courses (or typos, those happen too). I'm currently working on "What is a Join Table?", got about halfway through the video and started hitting errors (or lack of errors in some cases). Currently, around 9:50, when I run the 'should not update the status if nothing has changed' test (and after updating the controller), I'm getting an error for lines of code that don't exist in Jason's controller but do exist natively in mine.

I tried to add code line numbers to lines that were mentioned (on the right side).

Test:

test "should not update the status if nothing has changed" do
  sign_in users(:ej)
  patch :update, id: @status
  assert_redirected_to status_path(assigns(:status))
  assert_equal assigns(:status).user_id, users(:ej).id
end

statuses_controller.rb

# PATCH/PUT /statuses/1
# PATCH/PUT /statuses/1.json
def update
  @status = current_user.statuses.find(params[:id])
  if params[:status] && params[:status].has_key?(:user_id)
    params[:status].delete(:user_id)
  end
  respond_to do |format|                                                             48
    if @status.update(status_params)                                         49
      format.html { redirect_to @status, notice: 'Status was successfully updated.' }
      format.json { head :no_content }
    else
      format.html { render action: 'edit' }
      format.json { render json: @status.errors, status: :unprocessable_entity }
    end
  end
end

# DELETE /statuses/1
# DELETE /statuses/1.json
def destroy
  @status.destroy
  respond_to do |format|
    format.html { redirect_to statuses_url }
    format.json { head :no_content }
  end
end

private
  # Use callbacks to share common setup or constraints between actions.
  def set_status
    @status = Status.find(params[:id])
  end

  # Never trust parameters from the scary internet, only allow the white list through.
  def status_params
    params.require(:status).permit(:user_id, :content)                 77
  end
end

Error:

1) Error:
StatusesControllerTest#test_should_not_update_the_status_if_nothing_has_changed:

It looks like the status params aren't being set and are required. Try changing this:

def status_params
  params.require(:status).permit(:user_id, :content)
end

To this:

def status_params
  params.permit(:status).permit(:user_id, :content)
end

Let us know if that helps!

Did you ever get a solution to this problem? I am facing a similar one myself. As Jason Seifer suggested, I changed my params.require to params.permit; and ended up with errors on 3 more tests. As it stands I can't get my edit and destroy tests to pass.
