rails 4 populate dropdown values from database

Question

I have a dropdown in a rails form:

<%= f.select :lists, [[\"test1\", 1], [\"test2\", 0]] %>

This works fine but how can I make it dynamic

Answer 1

This worked for me

# view
<%= form.select(:list_id) do %>
    <% @list.each do |l| -%>
      <%= content_tag(:option, l.name, value: l.id) %>
    <% end %>
<% end %>

and

# controller
@list ||= List.all
