ruby - Correct way to add a comments to existing view rails -

i have rails application wih scaffold displays images via controllers show action. want add comments every picture. right way this? tried making second controller+model+view, rendered comments form partial in images show view , passed image id via parameter. works, don't think how it's supposed done. if know example project implements aomething please send me, couldn't find anything. thank help.

this typically handled nested resources:

#config/routes.rb resources :images #-> url.com/images/:id    resources :comments, only: [:create, :update, :destroy] #-> url.com/images/:image_id/comments end  #app/controllers/images_controller.rb class imagescontroller < applicationcontroller    def show       @image = image.find params[:id]       @comment = @image.comments.new    end end  #app/controllers/comments_controller.rb class commentscontroller < applicationcontroller     def create       @image = image.find params[:image_id]       @comment = @image.comments.new comment_params       redirect_to @image if @comment.save    end     private     def comment_params       params.require(:comment).permit(:body).merge(user_id: current_user.id)    end end 

you'll able show views follows:

#app/views/images/show.html.erb <%= @image.attribute %> <%= form_for [@image, @comment] |f| %>    <%= f.text_field :body %>    <%= f.submit %> <% end %> 

of course, put partial. there number of ways working, above way i'd handle it.
