Question

what i did:

rails g scaffold game optionselect:string
rake db:migrate

in my view inside the form_for(@game):

<div class="field">
  <%= f.label :optionselect %><br />
  <%= f.select( :optionselect, "id", { "Option 1" => "1", "Option 2" => "2"}) %>
</div>

what i want to do:

select a value from the selectbox and save the selected value in @game.optionselect

problem: there are no selectable values visible. when i leave out the f. in front of f.select the values are visible but are not being saved (which i’m aware of).

Answer 1

It is good practise to keep such collections in the model and create class method to prepare them, ex:

class Game < ActiveRecord::Base

  OPTIONS = [
    {:name => 'Option 1', :id => 1},
    {:name => 'Option 2', :id => 2},
    {:name => 'Option 3', :id => 3}
  ]

  def self.options
    OPTIONS.map{ |option| [option[:name], option[:id]] }
  end
end

then in the view:

= f.select :optionselect, Game.options
