多年来我一直在做 RoR,但这是我使用 Mongo 的第一个项目(也是我的第一个 api-only 项目)。我在 HABTM 协会方面遇到了困难,我怀疑它与参数有关,但我不确定还有什么可以尝试的。
这是我所拥有的:
class Project
include Mongoid::Document
field :name, type: String
field :start_date, type: Date
field :target_date, type: Date
has_and_belongs_to_many :users
end
class User
include Mongoid::Document
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:jwt_authenticatable, jwt_revocation_strategy: JWTBlacklist
field :email, type: String
field :_id, type: String, default: ->{ email }
{ ... devise stuff ...}
has_and_belongs_to_many :projects
end
在我的项目控制器中,我有这个参数:
def project_params
params.permit(:id, :name, :start_date, :target_date, :description, user_ids: [])
end
是的,我也试过做 {user_ids: []}。
当我使用 Postman 发出 URL PUT 请求以尝试将用户添加到项目时,我收到“不允许的参数”错误。但是......我允许那个参数,对吧?
我有点发疯了,因为我不知道我是否遇到了 Mongo 问题、Rails 5 问题或 API 问题。所有其他电话都工作正常。
