How do I define values in options_for_select?

Question:

Tag: ruby-on-rails,select,erb,options

I have this options_for_select call:

    <%= f.select(:agents, options_for_select(@agents), {},{multiple: true, size: 10, :id => "agents"}) %>

There are only currently 2 agents in the database but they are showing up as #<Agent:0x007fc1b121c490> format. I want them to display as @agent.name and for the value to be @agent.id.

How do I edit this code above to get this? Thank you!


Answer:

There is actually a helper specifically for collections, options_from_collection_for_select which is to handle exactly this case.

<%= f.select(:agents, options_from_collection_for_select(@agents, 'id', 'name'), {},{multiple: true, size: 10, :id => "agents"}) %>
