I have a couple of rails relationships.
class Customer < ActiveRecord::Base
has_many :sites
end
class Site < ActiveRecord::Base
belongs_to :Customer
end
I want to be able to get a list of sites ordered by the long-name field of the customer and then the long-name field of the site, I want to use the list in a select element on a page, where the individual options will look like this.
Ordered first by the Customer, and then the Sites for that Customer. I do not want to see Customers that have no sites.
I cannot figure out how to build my Site.find statement.
I'd go with somethig like this:
@sites = Site.find(:all, :joins => :customer, :order => "customers.long_name, sites.long_name")
And then,
@sites.each { |s| "#{s.customer.long_name} - #{s.long_name}" }
我会用
Site.all(:include => :customer, :order => "customers.name, sites.name")
