after installing https://github.com/pry/pry you can write something like:

<% @posts.each do |lst| %>
<% binding.pry %>
<h2> <%= lst.title %> </h2>
<h2> <%= lst.content %> </h2>

then when you refresh the page, in the terminal where you are running the server you will see that you get a console and you can see what values you have for lst variable
