Rails if current_page? on dynamically added elements

Question

I'm having trouble with if current_page? in a partial.

Section.html.erb

<div class="list" %>">
    <%= render partial: 'items/item', collection: section.items, :as => :item %>    
</div>

_item.html.erb

<% if current_page?(edit_polymorphic_path(@modulable)) %>

    <span class="action">
        <%= link_to %>
        <%= link_to %>
    </span>

<% end %>

The code works fine on a new page load and upon refreshing the page, but doesn't work on a dynamically added element with ajax.

Does this method work with Ajax? Am I doing something wrong? Or do I have to use another method?

Answer 1

I ended up using a different method. Instead of having the partial ask which page it's in, I passed a local variable to tell it what to do instead.

Section.html.erb

<div class="list" %>">
    <%= render partial: 'items/item', collection: section.items, :as => :item, local: { edit: true } %>    
</div>

_item.html.erb

<% if defined?(edit) && edit %> 
    <span class="action">
        <%= link_to %>
        <%= link_to %>
    </span>
<% end %>

And I made sure I passed in the local variable to the new element in update.js.erb

items/update.js.erb

$('.list').append(
    '<%= j (render partial: 'items/item', locals: { item: @item, edit: true }) %>'
    );

It works, and is more explicit.
