I’m a Ruby N. (hey that rhymes!) and I suspect I haven’t understood
the syntax properly.
I’m trying to assign one ActiveRecord object to the field of another and
I think this should work:
org = Organisation.new
=> #<Organisation:0xb7652dd8 @new_record=true,
@attributes={“fax_number”=>nil, “postal_address”=>nil, “name”=>nil,
“org_structure_id”=>0, “location_address”=>nil, “tin”=>nil,
“phone_number”=>nil, “contact”=>nil, “email_address”=>nil}>org.name = “Aces High Inc.”
=> “Aces High Inc.”person = NaturalPerson.new
=> #<NaturalPerson:0xb764997c @new_record=true,
@attributes={“postal_address”=>nil, “fax_number”=>nil, “name”=>nil,
“dob”=>nil, “phone_number”=>nil, “visa”=>nil, “mobile_number”=>nil,
“email_address”=>nil, “nationality”=>nil}>person.name = “Fred Flinstone”
=> “Fred Flinstone”org.contact << person
NoMethodError: You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.<<
from (irb):13
My Organisation model looks like this:
class Organisation < ActiveRecord::Base
belongs_to :org_structure
belongs_to :natural_person, {:foreign_key => “contact”}
has_many :natural_people, :through => :associates
validates_associated :org_structure
end
So by my understanding that second “belongs_to” call is supposed to
enable me to make the assignment that’s failing. It’s 1 o’clock in the
morning, maybe this will make sense after a sleep…
