如何查找具有当前用户的 Company_id

Question

我想用当前用户的company_id 创建一个新的jobdescription，但它不起作用，我尝试了不同的方法，它仍然不起作用。

所以，我不知道如何在我的控制器中构建查询，如果您能告诉我问题出在哪里，那您将非常好。谢谢。

Schema.rb

ActiveRecord::Schema.define(version: 20150212182839) do

  create_table "companies", force: true do |t|
    t.string   "company_name"
    t.string   "user_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end



  create_table "jobdescriptions", force: true do |t|
    t.string   "applyjobid"
    t.string   "job_title"
    t.string   "department"
    t.text     "shift"
    t.string   "work_location"
    t.string   "position_supervisor"
    t.string   "supervisor_position_supervisor"
    t.decimal  "rate_pay"
    t.text     "benefits"
    t.text     "other_benefits"
    t.text     "job_summary"
    t.text     "job_duties"
    t.text     "tasks"
    t.text     "results"
    t.text     "responsibilities"
    t.text     "knowledge"
    t.text     "skills"
    t.text     "abilities"
    t.text     "physical_requirement"
    t.text     "work_envir_condition"
    t.text     "protective_clothing_and_devices_required"
    t.text     "tools_or_equipment_required"
    t.text     "qualifications"
    t.text     "education_and_training"
    t.text     "license_certification"
    t.text     "experience"
    t.text     "aptitudes_interests_temperament"
    t.text     "roles_relationships"
    t.text     "supervisory_responsibility"
    t.text     "advancement_promotion_opportunities"
    t.string   "internal_comment"
    t.string   "submited_by"
    t.string   "approved_by"
    t.string   "statut"
    t.date     "from_date"
    t.date     "end_date"
    t.integer  "company_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "jobdescriptions", ["company_id"], name: "index_jobdescriptions_on_company_id"



  create_table "users", force: true do |t|
    t.string   "username"
    t.string   "country"
    t.string   "role_id"
    t.integer  "company_id"
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.integer  "current_sign_in_ip"
    t.integer  "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "users", ["company_id"], name: "index_users_on_company_id"
  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true

  create_table "users_roles", id: false, force: true do |t|
    t.integer "user_id"
    t.integer "role_id"
  end

  add_index "users_roles", ["user_id", "role_id"], name: "index_users_roles_on_user_id_and_role_id"

end

这是我的JobdescriptionsController

class JobdescriptionsController < ApplicationController
  layout 'application'



  def new
    @jobdescription = Jobdescription.new
  end

  def create

    @jobdescription = current_user.company_id.jobdescriptions.create(jobdescription_params)
    redirect_to new_jobdescription_path
  end

  private

  def jobdescription_params
    params.require(:jobdescription).permit(:applyjobid, :job_title, :work_location, :rate_pay, :shift, )
  end

end

型号Jobdescription

class Jobdescription < ActiveRecord::Base
  belongs_to :company


end

型号Company

class Company < ActiveRecord::Base
  has_many :users
  has_many :jobdescriptions

end

型号User

class User < ActiveRecord::Base
  rolify
  default_value_for :role_id, "1"
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  has_many :timesheets
    has_many :expenses
  belongs_to :company
end

Answer 1

我认为问题在于current_user.company_id 为该用户的公司提供了company_id 的整数值，而您真正想要的是获取公司对象实例本身。然后您可以在该公司实例上调用create。

所以@jobdescription 在create 方法中的赋值是：

@jobdescription = current_user.company.jobdescriptions.create(jobdescription_params)
