Учитывая эту модель в устаревшем коде с RoR 2.3.11:
class Assignment < ActiveRecord::Base
belongs_to :source_person
belongs_to :destination_person
belongs_to :laptop
def self.setScope(places_ids)
find_include = [:laptop => {:owner => {:performs => {:place => :ancestor_dependencies}}}]
find_conditions = ["place_dependencies.ancestor_id = (?)", places_ids]
scope = { :find => { :conditions => find_conditions, :include => find_include } }
Assignment.with_scope(scope) do
yield
end
end
end
Всякий раз, когда он достигает оператора Assignment.with_scope
, я получаю следующее исключение:
Assignment Delete all (0.0ms) Mysql::Error: Unknown column 'place_dependencies.ancestor_id' in 'where clause': DELETE FROM `assignments` WHERE (`id` IN (17)) AND (place_dependencies.ancestor_id = (1))
Моя схема выглядит так:
create_table "assignments", :force => true do |t|
t.date "created_at"
t.date "date_assigned"
t.time "time_assigned"
t.integer "source_person_id"
t.integer "destination_person_id"
t.integer "laptop_id"
t.text "comment"
end
add_index "assignments", ["destination_person_id"], :name => "assignments_destination_person_id_fk"
add_index "assignments", ["laptop_id"], :name => "assignments_laptop_id_fk"
add_index "assignments", ["source_person_id"], :name => "assignments_source_person_id_fk
create_table "place_dependencies", :force => true do |t|
t.integer "descendant_id"
t.integer "ancestor_id"
end
add_index "place_dependencies", ["ancestor_id"], :name => "place_dependencies_ancestor_id_fk"
add_index "place_dependencies", ["descendant_id"], :name => "place_dependencies_descendant_id_fk"
У меня практически одинаковый код на нескольких моделях, но там все отлично работает. Не могли бы вы дать мне подсказку, как решить эту проблему?
