Question

Problem: Ajax is not behaving as it should be.

PostIndex:

<tr>
  <td><%= post.name %></td>
  <td><%= post.created_at.strftime("%Y/%m/%d, %I:%M%p") %></td>
  <td><%= post.view %></td>
  <td id="post_like_<%= post.id %>"><%= post.like %></td>
  <td><%= link_to 'like', like_post_path(post), :remote => true %></td>
</tr>

like.js.erb:

$("#post_like_<%= post.id %>").html("<%= @post.like %>");

I can see the changes only after I refresh the page. Ajax is not working, but I failed to locate where the problem is in the above code.

Answer 1

You forgot the @ in your view. I see $post is in instance variable as I see $post.like. So, in your like.js.erb, replace post.id with @post.id. Like:

$("#post_like_<%= @post.id %>").html("<%= @post.like %>");
