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

You can use options_from_collection_for_select.

<% options = options_from_collection_for_select(@list, 'id', 'name') %>
<%= f.select :all_val,  options %>
