[英]How to make a Employee-Company relation in Rails?
我正在嘗試在 Ruby on Rails 上創建一個工作委員會。 我正在使用 devise 來處理帳戶,並且我有一個 Employee(設備用戶)和 Company 模型。
在這個挑戰中,當有人以員工身份創建帳戶時,我必須檢查公司域是否已經存在(該域是從員工電子郵件中提取的),如果不存在,則必須將員工重定向到注冊頁面公司。 此外,這名員工成為公司的管理員。
問題是,如何正確處理它們之間的關系? 如果我彼此之間使用 belongs_to 關系,則不可能在沒有公司的情況下創建員工,反之亦然。 如果我不這樣做,以后就無法訪問某些 ID 來建立正確的關系。 更糟糕的是,稍后我需要為招聘廣告創建一個 JobAd model,它應該屬於公司和員工。 那么,有沒有什么辦法可以在沒有“沒有公司的員工,反之亦然”的情況下實現這一點呢?
這是我的 schema.rb
ActiveRecord::Schema.define(version: 2021_02_23_032327) do
create_table "applicants", force: :cascade do |t|
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.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["email"], name: "index_applicants_on_email", unique: true
t.index ["reset_password_token"], name: "index_applicants_on_reset_password_token", unique: true
end
create_table "companies", force: :cascade do |t|
t.string "name"
t.string "logo"
t.string "address"
t.string "cnpj"
t.string "site"
t.string "social_media"
t.string "domain"
t.integer "employee_id", null: false
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["employee_id"], name: "index_companies_on_employee_id"
end
create_table "companies_employees", id: false, force: :cascade do |t|
t.integer "employee_id", null: false
t.integer "company_id", null: false
t.index ["company_id", "employee_id"], name: "index_companies_employees_on_company_id_and_employee_id"
t.index ["employee_id", "company_id"], name: "index_companies_employees_on_employee_id_and_company_id"
end
create_table "employees", force: :cascade do |t|
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.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["email"], name: "index_employees_on_email", unique: true
t.index ["reset_password_token"], name: "index_employees_on_reset_password_token", unique: true
end
create_table "job_ads", force: :cascade do |t|
t.string "title"
t.text "description"
t.integer "salary_range"
t.integer "level"
t.date "mandatory_requirements"
t.integer "total_vacancy"
t.integer "company_id", null: false
t.integer "employee_id", null: false
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["company_id"], name: "index_job_ads_on_company_id"
t.index ["employee_id"], name: "index_job_ads_on_employee_id"
end
add_foreign_key "companies", "employees"
add_foreign_key "job_ads", "companies"
add_foreign_key "job_ads", "employees"
end
我現在正在嘗試的是:
員工設備的 registration_controller.rb
class Employees::RegistrationsController < Devise::RegistrationsController
def after_sign_up_path_for(resource)
domain = resource.email.split('@').last
if domain_is_free?(domain)
@employee.save
redirect_to new_company_path
flash[:notice] = "Não identificamos o domínio #{domain}, por favor registre-o"
else
redirect_to root_path
end
end
def create
@employee = Employee.new(employee_params)
if @employee.save
sign_in(@employee)
after_sign_up_path_for(@employee)
else
render :new
end
end
protected
def domain_is_free?(employee_mail)
!Company.exists?(['domain LIKE ?', "%#{employee_mail.split('@').last}%"])
end
def employee_params
params.require(:employee)
.permit(:email, :password, :password_confirmation)
end
公司.rb
class Company < ApplicationRecord
belongs_to :employee
has_many :employees
has_many :job_ads
end
雇員.rb
class Employee < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
belongs_to :company, optional: true
end
rspec測試
require 'rails_helper'
feature 'employee creates an account' do
scenario 'and is the first to register a domain' do
visit root_path
click_on 'Employee registration'
within('form') do
fill_in 'Email', with: 'roger@jobs.com'
fill_in 'Password', with: '123456'
fill_in 'Password confirmation', with: '123456'
click_on 'Sign up'
end
expect(current_path).to eq new_company_path
expect(page).to have_content 'There is no company named jobs, please register it'
expect(page).to have_content 'Register Company'
end
最后是錯誤信息
Failure/Error:
params.require(:company)
.permit(:name, :logo, :address, :cnpj, :site, :social_media, :domain).merge(employee_id: current_employee.id)
ActionController::ParameterMissing:
param is missing or the value is empty: company
Did you mean? controller
action
我認為您對此處的關聯感到困惑,請嘗試從company.rb
文件中刪除belongs_to:employee
。
所以 belongs_to 的意思是 model A 的一個實例屬於 model B 的一個實例。這意味着 A 的實例不能沒有 B 的實例存在(例如 Book 不能沒有作者)。 查看此鏈接了解更多!
另外,如果您希望員工成為公司的管理員,請在 employee.rb 中添加 admin 字段為 boolean。
我不確定我是否理解了所有的事情......
belongs_to
關系時,您必須提供該表的外鍵。 在employee.rb
中,您編寫ruby belongs_to:company, optional: true
但不要將company_id
字段添加到employees
表中。 create_table "employees", force: :cascade do |t|
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.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["email"], name: "index_employees_on_email", unique: true
t.index ["reset_password_token"], name: "index_employees_on_reset_password_token", unique: true
end
class Employee < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
belongs_to :company, optional: true
end
也許你只需要這個has_one
來代替。
@employee.create_company(company_params)
在這種情況下,您不必將employee_id
與參數一起傳遞。 但是同樣,您應該將外鍵添加到 Employees 表或替換為Employee
model 中的has_one:company
。
employee
和company
。 將accepts_nested_attributes_for:company
添加到Employee
model,在 controller 中你可以這樣調用:
def create
...
@employee.create(employee_params)
...
end
def employee_params
params.require(:employee)
.permit(:email, :password, :password_confirmation, company_attributes: [:name, :logo, :address, :cnpj, :site, :social_media, :domain])
end
但它也只有在將company_id
字段添加到 Employee 表時才會起作用。 無論如何,你可以做同樣的反之亦然。
