Question

I have a status update, and comment db table.

A user has many status updates, and a status update has many comments. Similar to facebook, When a users friend goes to the users feed page (show page), they should be able to comment on the users status updates.

I’m having issues saving a users friends comment.. my code is below.. I think it has something to do with the Comments Controller, Create method, “@comment = @statusupdate.comments.build(params[:comment])”

any guidance is much appreciated! thanks!

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])
    @statusupdates = @user.statusupdates.paginate(:page => params[:page], :per_page => 25)
    @statusupdate = Statusupdate.new    
    @comment = Comment.new
  end
end

show.html.erb
  <% form_for @statusupdate do |f| %>
  <%= f.error_messages %>
  <div class="field">
    <%= f.text_field :content %>
  </div>

 <% @statusupdates.each do |s| %>

   <%= s.content %><br />

    <% form_for @comment do |f| %>
    <%= f.error_messages %>
      <div class="field">
        <%= f.text_field :comment %>
      </div>
      <div class="field">
        <%= f.hidden_field :user_id, :value => current_user.id %>
      </div>
      <div class="actions">
        <%= f.submit "Submit" %>
      </div>
      <br><br>
    <% end %>
  <% end %>

class CommentsController < ApplicationController
  def create
    @comment = @statusupdate.comments.build(params[:comment])
      if @comment.save
      flash[:success] = "Comment created!"
      redirect_to root_path
    else
      @feed_items = []
      render 'pages/home'
    end
   end
 end

Answer 1

show.html.erb- I changed the top line of the status update comment form to:

<% form_for (s, s.comments.build) do |f| %>
...

class CommentsController < ApplicationController
  def create
    @statusupdate = statusupdate.find(params[:statusupdate_id])
    @comment = @statusupdate.comments.create(params[:comment])
    ...

I don’t exactly know what’s going on here but it worked for me~ hope it helps someone out~
