Passing instance variables in nested partials in Rails?

Question

I am having difficulty passing instance variables in nested partials. Here is what I have done.

In controller Own:

def home
  @item = "some values"
  @ref = "some other values"
end

Then I have a home page "home.html.erb", in which I rendered "_product_table.html.erb":

<%= render "own/product_table", :item => @items, :ref => @ref %>

Then, in "_product_table.html.erb", I have to render "_product.html.erb":

<% @items.each do |item|%>
  <%= render "own/product", :item => item, :ref => @ref %>
<% end %>

I can't understand why the ref variable is not available in the "_product.html.erb" partial.

I'm slightly confused. So home.html.erb renders product_table.html.erb which renders product.html.erb which renders _product.html.erb? — Paul Richter

home.html.erb renders _product_table.html.erb and the _product_table.html.erb renders _product.html.erb — userkhan

You are passing ref as argument to the partial in home.html.erb, so in _product_table.html.erb you should use it similarly to item, not as instance variable:

<% @items.each do |item|%>
  <%= render "own/product", :item => item, :ref => ref %>
<% end %>

yes I tried that then I in href tag I did something like this. <div class="product" data-ref="<% ref %>"><a href="<%somevalues%>" data-ref = "<%ref%>">></div> but the values of data attribute did not append in the url on mouse hover which we see in the bottom left corner of chrome

Use <%= ref %> instead of <% ref %>.
