How to concatenate in ".erb" like haml

hello everyone i have a view _disqus.html.erb when i call that view i pass an object like this

render "disqus", product: product || render "disqus", product: post

and i wanna concatenate something like this

"#{product+"_path(product)""

because sometimes i send a post and sometimes i send a product and i dont wanna make other view for the posts so i just wanna concatenate the object.

code:

var disqus_config = function () {
    this.callbacks.onNewComment = [
      function() {        
        $.ajax({
          method: "PATCH",
          url: '<%= product_path(product) %>',          
          data: {increment: "comment_count"}
        })
      }
    ];
};

url: '<%= product_path(product) %>'

how can i concatenate ? thanks

in java would be something like this

product+"_path(product)"

"product would be = post or = product"

i tried with this

url: '<%= product+_path(product) %>'

but i get syntax error :(

In general product_path it's just a method. You can use metaprogramming for call method when you have a name as a string:

<%= send("#{product.class.name.downcase}_path", product) %>

Hope it helps
