So I'm trying to setup scaffolding to use radio buttons for the format button. It definitely works to add a new and edit. The problem is when I go to edit an entry the correct radio button isn't selected by default.
<% form_for(@cinema) do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>
<p>
<%= f.label :director %><br />
<%= f.text_field :director %>
</p>
<p>
<%= f.label :release_date %><br />
<%= f.date_select :release_date, :start_year => 1900, :end_year => 2010 %>
</p>
<p>
<%= f.label :running_time %><br />
<%= f.text_field :running_time %>
</p>
<p>Blockquote
<%= f.label :format %><br />
<%= f.radio_button :format, "black &
white" %>
<%= label :format_bw, "Black &
White" %>
<%= f.radio_button :format, "color" %>
<%= label :format_color, "Color" %>
</p>
<p>
<%= f.submit 'Create' %>
</p>
<% end %
Controller
def edit
@cinema = Cinema.find(params[:id])
end
Model
class Cinema < ActiveRecord::Base
validates_presence_of :title, :on => :create
validates_presence_of :title, :on => :update
#

validates_numericality_of :running_time, :on => :create, :on => :update, :less_than_or_equal_to => 300, :greater_than => 0
end
