Hey was wondering how to setup a select box that when I call  
Model.new(params[:model]) it will automatically putit into the db…

I tried  
  
0  
…

then when I do @home = Home.new(params[:home]) that field doesnt insert  
into the db… any ideas?

Did you remember to execute @home.save afterward?

Well it saves all the other information into the database, except for  
that one field… the select field.

Try changing it to:  
  
And see the magic happen…

Hey Ray,

if the Home attribute is “bedrooms”, as in Home.new().bedrooms, _and_  
you are getting params[:home] then the name attribute of your select  
tag should be “home[bedrooms]”.

The rails form helpers will keep you on the right track here:

[http://api.rubyonrails.com/classes/ActionView/Helpers/](http://api.rubyonrails.com/classes/ActionView/Helpers/)  
FormOptionsHelper.html#M000399

as in \<%= select :home, :bedrooms, [0,1,2,3,4,5] %\>

will create a select box with a name of home[bedrooms] with an option  
list from 0 through 5. Although I’ve not tried it you could probably  
use a ruby “Range” of (0…5) as well.
