Loop in Ruby on Rails html.erb file

erb, html, loops, ruby, ruby-on-rails

Solution

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)

Problem

everybody I'm brand new with Ruby on Rails and I need to understand something. I have an instance variable (@users) and I need to loop over it inside an html.erb file a limitated number of times. I already used this: ``` <% @users.each do |users| %> <%= do something %> <%end %> ``` But I need to limitate it to, let's say, 10 times. What can I do?
