Ruby on rails 将ruby rails模型类转换为lib文件夹中的类

我有下面的model/Admin.rb类，我想将其提取并转换为lib/UserApi类。我不熟悉创建lib类并能够从控制器调用它们。谢谢你的建议

class Admin
attr_accessor :id
attr_accessor :firstname
attr_accessor :lastname
attr_accessor :usergroups

def initialize json_attrs = {}
    @usergroups = []
    unless json_attrs.blank?
        @id = json_attrs["id"]
        @fname = json_attrs["fname"]
        @lname = json_attrs["lname"]
        @groups = json_attrs["groups"]
        @authenticated = true
    end
    if json_attrs.blank?
        @firstname = "blank"
    end
end

def is_authenticated?
    @authenticated ||= false
end

def in_groups? group_names
    return !(@usergroups & group_names).empty? if group_names.kind_of?(Array)
    @usergroups.include?(group_names)
end

def authenticate username, password
    options={:basic_auth => {:username => CONFIG[:API_CLIENT_NAME], 
                            :password => CONFIG[:API_CLIENT_PASSWORD]}}

    api_response = HTTParty.get("#{CONFIG[:API_HOST]}auth/oauth2?username=#{username}&password=#{password}", options)

    raise "API at #{CONFIG[:API_HOST]} is not responding" if api_response.code == 500 || api_response.code == 404

    if api_response.parsed_response.has_key? "error"
        return false
    else
        initialize(api_response.parsed_response["user"].select {|k,v| ["id", "fname", "lname", "groups"].include?(k) })
        @authenticated = true
        return true
    end
end

def full_name
    "#{@name} #{@name}"
end

结束

这是我目前在auth_控制器中使用的”

class Admin:：AuthController

在lib目录中创建UserApi类：

# lib/user_api.rb
class UserApi
 ...

更新控制器：

class Admin::AuthController < Admin::BaseController

def auth
    admin_user = UserApi.new
    auth_result = admin_user.authenticate(params[:username], params[:password])
end 

class Admin:：AuthController

加载放在lib/目录中的类，以便在控制器中可以访问它们：

我通常创建一个

config/initializers/00_requires.rb文件，并需要所需的lib文件

class Admin::AuthController < Admin::BaseController

def auth
    admin_user = UserApi.new
    auth_result = admin_user.authenticate(params[:username], params[:password])
end
