Is it possible to pass a counter value in the helper method? Or is it already available somewhere?


nathanvda commented Feb 18, 2012

Could you please explain the use-case: why do you need the numbering?


nathanvda commented Feb 18, 2012

Check http://guides.rubyonrails.org/layouts_and_rendering.html and search for counter. Normally this should be available for you as well. E.g. comment_counter if you are rendering a list of comments.

Thanks for the fast replies and sorry for my late reply. I did try the example given but somehow I got error saying as if the index has not been declared at all. I was actually trying to access any errors for the nested form using the index. For an example, I can do something like this with nested_form gem:

- @catalogue.item_catalogues.each.with_index do |item_catalogue, index|
  = render partial: 'form_item_catalogue', locals: { index: index, item_catalogue: item_catalogue, f: f }
= f.link_to_add "Add an item", :item_catalogues, style: "display: none"
= f.fields_for :item_catalogues, item_catalogue do |i|
  = normal_div_if @catalogue.item_catalogues[index].errors[:item].empty? do
    = i.label :item_id, "Item"
      = i.collection_select :item_id, Item.all, :id, :nama, {}, class: "chzn-select-nested span5"
      = i.link_to_remove "Delete", class: "btn danger"
        = @catalogue.item_catalogues[index].errors[:item].join(", ")

I am a bit lost. What are you replying to here? Which example did you try? This does not look like cocoon code. Did you try using the item_catalogue_counter as mentioned in the Rails guide?

amree commented Feb 19, 2012

I was in the rush earlier. This is actually some codes from my previous project that uses nested_form gem. What I'd like to do is that I'd like to be able to use something like this:


I can't do this with cocoon, so, I'm wondering if it's not possible with cocoon or maybe it's just because of my wrong codes. I'll post the code that uses cocoon later.

I do not understand: why not show the errors of the item itself?

You have something like

=f.fields_for :item_catelogues do |item_catalogue|

then you can just do something like item_catalogue.errors.
