ruby-on-rails - Heroku 生产环境上的 FactoryBot

Question

我正在尝试在 heroku 中使用 gem FactoryBot..
在本地一切正常，工厂已正确找到。
我正在尝试在 spec 文件夹之外使用工厂。

我在服务 invoice.rb 中使用它:

class InvoiceService
  @invoices ||= FactoryBot.build_list :invoice, 50, :with_invoice_positions
end

这是我的发票工厂的样子:

FactoryBot.define do
  factory :invoice do
    ...

    trait :with_invoice_positions do
      transient do
        invoice_positions_count 5
      end

      after(:build) do |invoice, evaluator|
        ...
      end
    end
  end
end

最后一件事是通过 Gemfile，我将 FactoryBot 行放在 :test 组之外:

ruby '2.5.0'
source 'https://rubygems.org'

gem 'rails', '~> 5.1.4'
gem 'pg', '~> 0.18'
gem 'puma', '~> 3.7'
...
gem 'factory_bot_rails', '~> 4.8.2'
gem 'faker', git: 'https://github.com/stympy/faker.git', branch: 'master'
...

group :production do
  gem 'rails_12factor', '~> 0.0.3'
end

group :development, :test do
  ...
end

group :development do
  ...
end

group :test do
  ...
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

尝试在 heroku 上运行 rails server 时出错:

有人在生产模式下成功使用工厂机器人吗？

Answer 1

默认情况下，factory_bot 不会将自己包含在任何地方，仅在您通常会使用它的规范中。

尝试做

require 'factory_bot'
FactoryBot.find_definitions

在 invoice.rb

如果可行，您可以在初始化程序中添加具有相同内容的 factory_bot.rb 文件，以便在 Rails 应用程序启动时加载它(取决于您的偏好)
