而不是require 'rails/all'
需要所有 Railties,包括 ActiveRecord,您需要明确要求您要使用的 railties:
require File.expand_path('../boot', __FILE__)
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
# require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
# require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
module Draw
class Application < Rails::Application
# You don't need this nonsense since you don't even have config/application.yml
# ENV.update YAML.load_file('config/application.yml')[Rails.env] rescue {}
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de
# Do not swallow errors in after_commit/after_rollback callbacks.
# config.active_record.raise_in_transactional_callbacks = true
end
end
如果你不想使用 ActiveRecord,你可以去掉/db
and /config/database.yml
。
您也不需要gem 'rake'
在 Gemfile 中添加 have,因为 rails 无论如何都依赖于它。
