Loop in Ruby on Rails html.erb file

You could do

<% for i in 0..9 do %>
  <%= @users[i].name %>
<% end %>

But if you need only 10 users in the view, then you can limit it in the controller itself

@users = User.limit(10)

If @users has more elements than you want to loop over, you can use first or slice:

Using first

<% @users.first(10).each do |users| %>
  <%= do something %>
<% end %>

Using slice

<% @users.slice(0, 10).each do |users| %>
  <%= do something %>
<% end %>

However, if you don't actually need the rest of the users in the @users array, you should only load as many as you need by using limit:

@users = User.limit(10)
