Ruby on rails Ruby/Rails-如何接受表单上具有多通关系的嵌套属性？

我正在rails中构建一个web应用程序，我对嵌套属性非常陌生。我正在尝试创建一个制作，我需要同时注册客户、候选人和交易参数

我发现嵌套属性是最好的解决方案，但如果将其标识为“未经许可的参数”（这是终端所说的），它就不起作用了

我用与客户、候选人和交易的关系建立了我的Facture模型，但我决定创建一个中间表，以便通过Facture和其他模型之间的关系创建has\u many

但这并不能解决问题。我想我错过了一些东西，也许我应该打电话给id，但我真的不知道怎么做

这是我的型号代码：

class Facture < ApplicationRecord
    belongs_to :delais_paiement 
    belongs_to :service 
    belongs_to :marche 
    belongs_to :team 
    belongs_to :status_facturation 
    belongs_to :condition_facturation 
    has_many :candidats, through: :informations_factures
    has_many :clients, through: :informations_factures
    has_many :deals, through: :informations_factures
    has_many :informations_factures 

    accepts_nested_attributes_for :candidats
    accepts_nested_attributes_for :informations_factures
    accepts_nested_attributes_for :clients
    accepts_nested_attributes_for :deals
end

class Deal < ApplicationRecord
    belongs_to :client
    has_many :factures, through: :informations_factures
    has_many :informations_factures

    accepts_nested_attributes_for :factures
end
class Client < ApplicationRecord
    has_many :factures, through: :informations_factures
    has_many :informations_factures
end

class Candidat < ApplicationRecord
    has_many :factures, through: :informations_factures
    has_many :informations_factures
end

class InformationsFacture < ApplicationRecord
    belongs_to :candidat
    belongs_to :client
    belongs_to :deal
    belongs_to :facture
end

以下是我的最终行动：

我错过了什么

错误“unpermitted parameters”意味着这是控制器中的问题，特别是“strong parameters”代码

我认为问题在于您为嵌套对象指定允许属性的方式

这是一个未经测试的版本，我认为你的制作参数方法应该是这样的。您可能需要进行一些测试和修改，以使其完全正确。特别是，嵌套参数是否需要包含id字段取决于您是希望接受参数只是为了创建新对象，还是为了更新现有对象

def facture_params
 params.require(:facture).permit(
   :condition_facturation_id, 
   :service_id, 
   :team_id, 
   :salaire,
   :clients_attributes => [:name, :id],
   :deals_attributes => [:deal_date, :start_date],
   :candidats_attributes => [:name, :id_janus, :id]
  )
end

谢谢你的回答！我试过了，但这并没有改变他们仍然是不被允许的。如果没有更多的信息，我无法让我的答案更精确，但请仔细阅读Rails指南，并尝试一些变体@EliseSerres执行此操作时，终端中现在显示的错误是什么？我认为这个问题可能是在你做字段的时候，在字段中，你应该做：交易、候选人和客户，而不是你单一的方式
