Can you post the relevant routes you have?

and comments belong_to :messages right? if so, add it in the routes

  map.resources :articles do |articles|     articles.resources :messages do |messages|       messages.resources :comments     end   end

It is better practice to have a CommentsController to operate on your comments instead of using the Messages controller. I highly suggest that you then use this tutorial as your starting point to move forward:

Good luck.

Hi Franz,

Thanks, ive got a comments controller being used now, along with a partial link,

<% for message in @messages %> <%= render :partial => @comment = Comment.new, :locals => { :button_name => 'Post'}%> <% end %>

this creates commments but without a message_id

so I need to somehow pass the message_id to the partial so that it goes into the database.

any ideas?

If you have your association setup properly between Message and Comment models, then you can do

@comment = message.comments.new

Can you try this in your console?

m = Message.find(:first) c = m.comments.new

That should automatically set c.message_id to m.id to make the association.

yep that works spot on.

OK, so the associations are in place.

Can you show the form you use for creating/editing comments? Assuming that in your CommentsController, you have a before_filter to get the @message à la:

@message = Message.find(params[:message_id])

and in your new method: @comment = @message.comments.new while in your edit method: @comment = @message.comments.find(params[:id])

You have to make sure that in your form, you do

<% form_for([@message, @comment]) do |f| -%>   <!-- form body --> <% end -%>

and of course if you nested Message under Article, it would be

<% form_for([@message.article, @message, @comment]) do |f| -%>
