Question

在注册过程中，我有一个用户模型和租户模型。最近我在Tenant模型中添加了一个序列化列，我可以更新这个专栏。但是，在创建新租户时，我设计了通过嵌套参数创建租户，并收到以下错误： ActiveRecord::SerializationTypeMismatch (Attribute was supposed to be a Hash, but was a String. -- "{}")：重要的是要注意我在注册过程中没有触及该列，我尝试将该列包含在消毒剂上，但它也是如此。在架构上有一个默认值“{}”。下面是一些代码：

create_table "tenants", force: :cascade do |t|
   t.string   "tenant_name"
   t.string   "tenant_address"
   t.string   "tenant_city"
   t.string   "tenant_zip"
   t.string   "tenant_phone"
   t.datetime "created_at",                     null: false
   t.datetime "updated_at",                     null: false
   t.boolean  "authorized"
   t.boolean  "trial"
   t.string   "plan_id"
   t.string   "plan_name"
   t.string   "braintree_id"
   t.string   "subscription_id"
   t.jsonb    "preferences",     default: "{}", null: false
   t.string   "tenant_state"
   t.string   "tenant_country"
   t.index ["preferences"], name: "index_tenants_on_preferences", using: :gin

端

class Tenant < ApplicationRecord
  has_many :users, :dependent =>  :delete_all
  has_many :customers, :dependent =>  :delete_all
  has_many :work_orders, :dependent =>  :delete_all
  has_many :vehicles, :dependent =>  :delete_all
  has_many :suppliers, :dependent => :delete_all
end

 serialize :preferences, Hash
 store_accessor :preferences, :state_tax, :mun_tax, :welcome_sms,       :estimate_sms, :completed_sms, :disclaimer

以下是我的用户控制器的一部分：

   class Users::RegistrationsController < Devise::RegistrationsController
     before_action :configure_sign_up_params, only: [:create]
     # before_action :configure_account_update_params, only: [:update]

   # GET /resource/sign_up
    def new
      build_resource({})
      self.resource.tenant = Tenant.new
       respond_with self.resource
     end

   # POST /resource
    def create
    super
    if @user.save
     @result = Braintree::Customer.create(
        :first_name =>  @user.name,
        :last_name => @user.lastname,
        :company => @user.tenant.tenant_name,
        :email => @user.email,
        :phone => @user.phone
        )
         if @result.success?
         @user.tenant.set_braintree_id(@result.customer.id)
         flash[:notice] = 'Thanks you!  and Welcome to Autokick.tech enjoy    your free 30 days!'
        else
          flash[:notice] = @result.errors
        end
      end
    end

Answer 1

t.jsonb "preferences", default: "{}", null: false

默认值为字符串"{}"，如错误所示将其更改为default: {}，不带引号。

使用Devise嵌套参数模型失败注册具有序列化列
