you need to add `has_many :people` to your Group class

Hi, it's me again ...
:-)
I have one table called people and another one called groups.
Each person from people belongs to ONE group.
module List::Models
class Person < Base
belongs_to :group
end
class Group < Base
end
end
When I get all persons from people, I expect, like in RoR, the access to
related records, like:
module List::Views
def people(xml)
xml.posts do
@posts.each do |person|
xml.person do
xml.id(person.id)
xml.name(person.name)
xml.surname_01(person.surname_01)
xml.surname_02(person.surname_02)
xml.has_come(person.has_come)
xml.group(person.group.name) # Here I'm asking for related
information about the group name
end
end
end
end
end
and I'm getting => NoMethodError at /people/list undefined method `name'
for nil:NilClass
also, I'm trying to test it on Console:
MacBook-ProII-2:Test montx$ camping -C list.rb
** Starting console
>> Person.find(1)
NameError: uninitialized constant Person
