我正在尝试在我的web应用程序上创建表单，以便具有正确权限的用户可以向数据库添加新的“站点”。我有一个名为site的数据库表，它在本地计算机上具有所有正确的属性。在表单上单击submit按钮时，出现以下错误。我尝试使用属性访问器，但它导致我以前的许多测试失败。有没有一种不用属性访问器就可以解决这个问题的方法？
错误：
admin:：addsitescontroller中的nomethoderror#为nil:nilclass创建未定义的“write_from_user”方法

  1. def create
  2.       site = Site.new(site_params) <-- highlighted in error message
  3.       authorize(site)

模型

  1. class Site < ApplicationRecord
  2.   include ActiveModel::Model
  3.   self.table_name = "site"
  5.   validates :name, presence: true
  6.   validates :address, presence: true
  7.   validates :year_built, inclusion: {in: 1700..Date.today.year, message: "that year is fake"},
  8.                           allow_nil: true
  9.   validates :number_of_floors, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  10.   validates :total_floor_area, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  11.   validates :number_of_units, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  12.   validates :primary_use_type, presence: true
  13.   validates :number_of_bedrooms, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  14.   validates :people_per_bedroom, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  15.   validates :water_performance_goal, numericality: {only_integer: true, greater_than: 0}, allow_nil: true
  17.   belongs_to :organization
  18.   belongs_to :weather_station
  19.   has_many :site_users, dependent: :destroy
  20.   has_many :users, through: :site_users
  22.   enum primary_use_type: {
  23.     commerical: "Commercial",
  24.     residential: "Residential"
  25.   }
  26.   enum building_type: {
  27.     affordable: "Affordable",
  28.     market_rate: "Market Rate"
  29.   }
  30.   enum population_type: {
  31.     family: "Family",
  32.     elderly_disabled: "Elderly/Disabled",
  33.     mixed_other: "Mixed/Other"
  34.   }
  35.   enum construction_type: {
  36.     brick_block: "Brick/Block",
  37.     concrete_slab: "Concrete/Slab",
  38.     wood_steel: "Light Framed Wood/Steel",
  39.     timber_steel: "Heavy Framed Timber/Steel"
  40.   }

控制器

  1. module Admin
  2.   class AddSitesController < ApplicationController
  3.     def new
  4.       @site = Site.new
  6.       authorize(@site)
  7.     end
  9.     def create
  10.       site = Site.new(site_params)
  12.       authorize(site)
  14.       if site.valid?
  15.         site.save
  16.         flash[:notice] = "good"
  17.         redirect_to admin_superusers_path
  18.       else
  19.         flash[:messages] = site.errors.full_messages
  20.         redirect_to admin_manage_sites_path
  21.       end
  22.     end
  24.     private
  26.     def site_params
  27.       params.require(:site).permit(
  28.         :organization_id,
  29.         :name,
  30.         :address,
  31.         :year_built,
  32.         :construction_type,
  33.         :number_of_floors,
  34.         :total_floor_area,
  35.         :number_of_units,
  36.         :weather_station_id,
  37.         :primary_use_type,
  38.         :building_type,
  39.         :population_type,
  40.         :number_of_bedrooms,
  41.         :people_per_bedroom,
  42.         :water_performance_goal,
  43.         :sro
  44.       )
  45.     end
  46.   end
  47. end
