I have this code:
<%= f.select :name, [@m.each do |n| [ n.first_name , n.first_name ] end], :class => 'gam' %>
and i want it to display each of the first_name records from the table that @m is associated with in a drop-down. When i test this code the only option in the drop down menu it #Player:0x3c88008> (Player is the name of the table that @m is associated with) i know from previous testing that everything works fine besides this code.
Any ideas or help would be fantastic!
I have this code:
<%= f.select :name, [@m.each do |n| [ n.first_name , n.first_name ] end], :class => 'gam' %>
#each returns @m, so what you want is #map or collect. Try
<%= f.select :name, @m.map { |n| [n.first_name, n.first_name] }, :class => 'gam' %>
There's an optimization for this: collection_select
f.collection_select( :name, @m, :first_name, :first_name, :class => 'gam' )

You're right Walter but make sure to add an empty hash before the html options for the options parameter
f.collection_select :name, @m, :first_name, :first_name, {}, :class => 'gam'
Something like that?
<%= f.select :city_id, @cities.map { |city| [city.name, city.id] } %>
