使用nested_form（has_many belongs_to 关联）更新另一个对象时如何创建一个对象

Question

我有两个模型，Clients 和 Calls，有一个 has_many - belongs_to 关联。我想在每次更新客户端时创建一个新呼叫。使用nested_form，我能够创建它，但它生成的是一个没有参数的空对象。

模型.rb

class Call < ActiveRecord::Base

    belongs_to :client
    has_and_belongs_to_many :interests

end


class Client < ActiveRecord::Base

    has_many :calls, :dependent => :destroy
    belongs_to :user
    has_and_belongs_to_many :interests
    accepts_nested_attributes_for :calls

end

calls_controller.rb

class Admin::CallsController < ApplicationController
  before_action :set_call, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!
  layout 'admin'


  # GET /calls
  def index
    @calls = Call.order(created_at: :desc)

  end

  # GET /calls/1
  def show
    @calls = Call.order(created_at: :desc)
  end

  # GET /calls/new
  def new
    # @call = Call.new
  end

  # GET /calls/1/edit
  def edit
  end

  # POST /calls
  def create

    @client = Client.find(params[:client_id])
    @call = @client.calls.create(call_params)


    if @call.save
      redirect_to [:admin, @client], notice: 'Atendimento criado  com sucesso.'
      @call.create_activity :create, owner: current_user

    else
      render :new
    end
  end

  # PATCH/PUT /calls/1
  def update
    # if @call.update(call_params)
    #   redirect_to @call, notice: 'Artigo editado com sucesso.'

    # else
    #   render :edit
    # end
  end

  # DELETE /calls/1
  def destroy
    @client = Client.find params[:client_id]
    @call = @client.calls.find params[:id]
    @call.destroy
    redirect_to (:back), notice: 'Atendimento excluído.'
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_call
      @call = Call.find(params[:id])
    end


    # Only allow a trusted parameter "white list" through.
    def call_params
      params.require(:call).permit(:resume, :calltype, :client_id, interest_ids:[])

你能不能在控制器中做这样的事情，放在客户端更新块内。

@call = Call.new
@call.calltype = somevalue
@call.resume = someothervalue
@call.client_id = valueofclientid
@call.save

看起来值是 resume、calltype、client_id、interest_ids？您是否可以访问您想要为那里的人提供的值？

我会在下面将此方法称为 make_new_call 之类的方法，然后直接调用它，但这取决于您。

 def make_new_call
 // put the Call.new -> call.save code in here
 end

然后在那个方法中

   if @client.update(client_params)
       make_new_call
       redirect_to admin_clients_path(current_user), notice: 'Cliente atribuído ao corretor '
       # ClientMailer.client_user_set(@client).deliver_now
     else
       render :edit
     end
