Radio Button Helper - default value

Question

I have dining rooms and I have a type field (Single, Double). I want to use the switch for this field. So, I use it as follows:

 <% form_for(@room) do |f| %> <%= f.radio_button :type, "Single" %> <%= f.radio_button :type, "Double" %> <% end %> 

This is great for editing. The problem is that for the new view, I want to switch to "Single" by default. For this code, the value is not checked for the new view.

Now I'm setting it up with a status check

 <% form_for(@room) do |f| %> <%= f.radio_button :type, "Single", :checked => @room.new_or_single? %> <%= f.radio_button :type, "Double" %> <% end %> 

Room model

 def new_or_single? type.nil? or type == "Single" end 

Is there a better way to achieve this?

Answer 1

Set default value: enter constructor

 def new @room = Room.new(:type => "Single") end
