Drop down with model info

Rails
1

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!

#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’ )

Something like that?

<%= f.select :city_id, @cities.map { |city| [city.name, city.id] } %>

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’
