ruby on rails - How to setup the actions with considering database design of rails3 -


Assume that you have a model named 'topic' in the form of a parent, and ' Comment'. On the URL 'Subject / Show / 35' you can see all comments related to this topic ID # 35.

When the logged-in user wants to post a new comment on this page, should I write 'Comment_create' in action_controller.rb? Or just write the 'create' function in comments_controller.rb, and call it from this page? Which method is regular ??

If I call the 'create' action in comments_controller, then how can I write to pass

  1. To add comments' model name '
  2. ' Model ID # '
  3. ' Comment body '

    Or should I write a different way in this way?

    Controllers / comments_controller.rb 

      def create_in_topic code here! The new comment is related to the topic which is related to the reference ... .def creation_in_user code here!   
     For your information, commenting should add something like this.  
      def make @topic = Topic.find (params [: topics] [: id]) @user_who_commented = current_user @comment = comment .build_from (@topic, @ user_who_commented.id, params [ : Topics] [: body]) @ comment.save Redirect_to: back flash [: notice] = "comment added!"  
       example  & lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Id & lt; / Th & gt; & Lt; Th & gt; Title & lt; / Th & gt; & Lt; Th & gt; Body & lt; / Th & gt; & Lt; Th & gt; Subject & lt; / Th & gt; & Lt; Th & gt; Posted by & lt; / Th & gt; & Lt; Th & gt; Remove & lt; / Th & gt; & Lt; / TR & gt; & Lt;% @ topic.comment_threads.each | Comment | & Gt%; & Lt; TR & gt; & Lt; Td> & Lt;% = comment.id% & gt; & Lt; / Td> & Lt; Td> & Lt;% = comment.title% & gt; & Lt; / Td> & Lt; Td> & Lt;% = comment.body% & gt; & Lt; / Td> & Lt; Td> & Lt;% = comment.subject% & gt; & Lt; / Td> & Lt; Td> & Lt;% = comment.user.user_profile.nickname If Comment.User.user_profile% & gt; & Lt; / Td> & Lt; TD & gt; ** Comment Destination Method Needed Here !!! ** & lt; / Td> & Lt; / TR & gt; & Lt;% end% & gt; & Lt; / Table & gt; & Lt;% = form_for: topics, url: url_ ((Controller =>: Subject: verb = & gt ;: add_comment) do; f | & gt;; & lt; div class = "field" & gt; ; <% = F.label: 'Comment'% & gt; & lt; br / & gt; & lt;% = f.text_field: body% & gt; & lt; / div & gt; & lt; % = F.hidden_field: id ,: value = & gt; @ Topic.id% & gt; & lt; div class = "verb" & gt; & gt;% = f.submit%> & gt; & lt;% End%>   
     controllers / topics_controllerRbb  
      def add_comment @topic = Topic.find (params [: topics] [: id]) @user_who_commented = current_user @ comment = comment .build_from (@topic, @ user_who_commented.id, params [: topics] [: body]) @ comment.save redirect_to: back flash [: notice] = "comment added!" I think the most direct forward execution is this one verb (ie: Add_comment). Once you call the TopicController # add_comment operation in your Subject Controller, you will also receive all your information and commentary data so that you can easily add comments on that topic.
