Answer 1

You have @posts variable defined as a ActiveRecord::Relation (some kind of models array, defined with @posts = Post.all or anything like that). To fix your issue, if you have link_to call inside index url, most probably you are doing something like:

<% @posts.each do |post| %>
  # link_to call somewhere here
<% end %>

Then you have to change your link_to call to

<%= link_to 'Destroy', post_path(post),
          method: :delete,
          data: { confirm: 'Are you sure?' } %>

Notice we use variable defined in .each do |var| block, here it's post
