Factory_bot ActiveRecord :: RecordInvalid

问题描述 投票：0回答：2

无法理解错误的来源，这就是为什么我的标题如此尴尬。我的所有规范都随机引发了ActiveRecord :: RecordInvalid错误（一次测试引发，下一次没有）。这是repo https://github.com/artemaminov/frenchesna的链接

模型狗

class Dog < ApplicationRecord
  belongs_to :mother, class_name: 'Dog', foreign_key: 'mother_id', optional: true
  belongs_to :father, class_name: 'Dog', foreign_key: 'father_id', optional: true
  has_many :kids, class_name: 'Dog'

  has_many :pictures, class_name: "Image", inverse_of: :dog
  belongs_to :avatar, class_name: "Image", optional: true
  belongs_to :background, class_name: "Image", optional: true

  accepts_nested_attributes_for :pictures, :kids, allow_destroy: true

  # scope :background, -> { joins(:pictures).where(background: true) }

  enum gender: { male: 1, female: 0 }

  validates :name, :nickname, :birthdate, :gender, :award_point, :about, :rip, presence: true
end

模特图片

class Image < ApplicationRecord
  belongs_to :dog, inverse_of: :pictures

  has_one_attached :file
end

狗的工厂

    rip { Faker::Boolean.boolean }
    gender { Faker::Number.between(0, 1) }

    trait :with_pictures_uploaded do
      transient {
        images_count { 1 }
      }

      after(:create) do |dog, evaluator|
        build_list(:image, evaluator.images_count, dog: dog) do #Why order is empty
          file_path = Rails.root.join('spec', 'support', 'assets', 'dog-thumb.jpg')

更新1仅将代码缩小为狗。一样

  validates :name, :nickname, :birthdate, :gender, :award_point, :about, :rip, presence: true

据我说，你需要使用has_one而不是belongs_to。所以，替换这个

belongs_to :avatar, class_name: "Image", optional: true

以下 - 

has_one :avatar, class_name: "Image"

更新它涉及：背景协会也。

在这里描述你的数据库 - https://www.dbdesigner.net/以便更好地理解。

解决了。问题出在boolean和enum验证器上。这是解决问题的方法

狗的模特

Before
validates :name, :nickname, :birthdate, :gender, :award_point, :about, :rip, presence: true

After
validates_presence_of :name, :nickname, :birthdate, :award_point, :about
validates_inclusion_of :gender, in: %w(male female)
validates_inclusion_of :rip, in: [true, false]

狗的规格

Before
it { is_expected.to validate_presence_of :rip }
it { is_expected.to define_enum_for(:gender) }

After
it { is_expected.to validate_inclusion_of(:rip).in_array([true, false]) }
it { is_expected.to define_enum_for(:gender).with_values(male: 1, female: 0) }
