return 角色名称如何在 has_many 关联中响应资源化模型？

Question

我的应用使用 rolify 来管理多个角色。我已正确配置关联，但我需要在 dispute.users.

的响应中添加 角色名称

看看我下面的联想：

class Dispute < ApplicationRecord
  resourcify

  has_many :users, through: :roles

  ...
end

class UsersRole < ApplicationRecord
  belongs_to :user
  belongs_to :role
end

class User < ApplicationRecord
  ...

  rolify

  has_many :users_roles
  has_many :roles, through: :users_roles
  has_many :disputes, through: :roles, source: :resource, source_type: 'Dispute'

  ...
end

此时的响应是这样的：

[
  {
    "id": "90301da1-5ab6-4834-9865-30dc678043f1",
    "cpf": "11201300266",
    "name": "Convidado",
    "email": "convidado@gmail.com"
    "role": "guest" <<< This not exists yet! How add this column on response?
  }
]

您可以使用一些东西来序列化对象，例如 ActiveModelSerializer(https://github.com/rails-api/active_model_serializers)

所以你只需要像这样创建 UserSerializer：

class SomeSerializer < ActiveModel::Serializer
  attributes :id, :cpf, :name, :email, :roles

  def roles
    object.roles.pluck(:name)
  end
end

return 角色名称如何在 has_many 关联中响应资源化模型？

How return role name in has_many association at response of a resourcify model?
