Iterating through an Instance Variable in my View

Rails
1

I have an instance variable called @ls which is an array that contains a
list of files in a directory.

When I call this instance variable in my view like this:

<%= @ls %>

It shows the entire list of files in the array.

Since I need to edit what is displayed for each file name in the array,
I want to iterate through it in my view.

When I put this code in my view:
<% @ls.each do |a| %>
a.puts
<% end %>

… it only prints out the letter “a” as many times as the size of the
array.

Can anyone help me out with correcting this issue?

thanks

Because there’s an implicit to_s on the contents of <%= %>

array.

You probably want them in some sort of list, right?

    <% @ls.each do |a| %>
  • <%= a %>
    • <% end %>

Replace the ul/li markup with whatever makes sense for your results.
