我正在将rails应用程序从版本3.2.x升级到4.0.8,我在制作(版本2.11.3)上的ar类(位置)属于类别(而且HMBT类别),反过来一个类别属于类型学,
class Location
belongs_to :category
has_many :location_categories
has_many :categories, through: :location_categories
validates :title, :presence => true
validates :address_city, :presence => true
validates :nation_id, :presence => true
validates :phone, :phone_format => true
validates :mobile, :phone_format => true
validates :fax, :phone_format => true
validates :email, :email_format => true
validates :url, :url_format => true, :allow_blank => true
validate :validate_category_default
validates_attachment :logo, size: { in: 0..1.megabytes }, content_type: { content_type: [ 'image/jpg', 'image/jpeg', 'image/png', 'image/gif' ]}, if: Proc.new {|a| a.logo.present? }
validates_with VersionValidator, :on => :update
private
def validate_category_default
errors.add(:category_ids, I18n.t('activerecord.errors.messages.location.category_default')) unless category_ids.detect{|category| category == category_id }
end
# other stuff...
end
class Category
belongs_to :typology
validates :typology_id, :uniqueness => { :scope => :site_id }
validates :title, :presence => true, :uniqueness => { :scope => :site_id }
validates_with VersionValidator, :on => :update
# other stuff...
end
class Typology
validates :logic_title, :presence => true, :uniqueness => true
validates_attachment :image, size: { in: 0..1.megabytes }, content_type: { content_type: [ 'image/jpg', 'image/jpeg', 'image/png', 'image/gif' ]}, if: Proc.new {|a| a.image.present? }
validates_with VersionValidator, :on => :update
# other stuff...
end
然后在相对于Location的制造者上,当创建一个对象时,它还会触发类别和类型学相关的创建:
Fabricator(:location) do
category(fabricator: :category)
category_ids { |attrs| [ attrs[:category][:id] ] }
# other stuff...
end
Fabricator(:category) do
typology(fabricator: :typology)
# other stuff...
end
Fabricator(:typology) do
# other stuff...
end
现在的情况是我在轨道4上创建位置时检测到一个问题(在轨道3上工作正常),这是堆栈跟踪:

但我不明白是什么导致它的。
