我在文件夹openai.rb中app/services/openai/需要“net/http”需要“uri”需要“json”

class OpenAI
  def initialize(api_key)
    @api_key = api_key
  end

  def generate_comments(number_of_comments, post_description, customer_query)
    # some code ...
  end
end

我也将其包含在 application_controller.rb 中

require_relative "../services/openai/openai"

以前我通过重命名文件夹、模块和类解决了这个问题，但现在它变得太烦人了，因为类被命名OpenAI，但 rails 试图找到Openai

    来自官方指南

    默认情况下，Rails 将 Zeitwerk 配置为使用 来变形文件名String#camelize。例如，它期望app/controllers/users_controller.rb定义常量，UsersController因为这就是"users_controller".camelize返回的内容。

    这意味着some_entity.rb应该包含SomeEntity类（或模块）。文件夹也一样，文件夹名称应该与命名空间（模块）名称相对应

    我openai.rb有app/services/openai/

    在这种情况下，Rails awaitOpenai::Openai常量。如果你的常量是OpenAI，你应该将文件移动到app/services/openai.rb并自定义词形变化

    # config/initializers/zeitwerk.rb
loader = Rails.autoloaders.main

loader.inflector.inflect(
  'openai' => 'OpenAI',
)

    或者

    # config/initializers/inflections.rb
ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.acronym 'OpenAI'
end
