Rails控制器/設計請參閱空參數

Question

我已經創建了一個表單供用戶註冊我的應用程序，並通過添加能夠包含其公司名稱的小調整來註冊。但是，我的rspec測試並通過手動測試顯示參數未被傳遞以創建用戶/公司。

最後，我需要能夠創建一個user，並創建一個company，現在只需要公司名稱。

這裏有一個視覺的註冊形式：

RegistrationsController：

class Users::RegistrationsController < Devise::RegistrationsController 
    before_action :sign_up_params 

    def new 
    build_resource(sign_up_params) 
    self.resource.company = Company.new 
    respond_with self.resource 
    end 

    protected 

    def sign_up_params 
    devise_parameter_sanitizer.permit(:sign_up) do |user| 
     user.permit(:email, :name, :password, :password_confirmation, company_attributes: [:name]) 
    end 
    end 
end 

型號Company.rb

class Company < ApplicationRecord 
    validates_uniqueness_of :domain, :stripe_id 
    validates_presence_of :name 
    has_many :users 
    has_many :devices 
    has_one :subscription 

end 

模型User.rb

class User < ApplicationRecord 
    devise :database_authenticatable, :registerable, :lockable, 
     :recoverable, :rememberable, :trackable, :validatable 
    validates_uniqueness_of :email 
    validates_presence_of :email, :name 
    belongs_to :company 
    accepts_nested_attributes_for :company 
end 

我的登記表：

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %> 

    <%= f.fields_for :company do |company_form| %> 
     <%= company_form.text_field :name, class: 'form-control', autofocus: true, placeholder: 'ACME Inc.' %> 
    <% end %> 

    <%= f.text_field :name, class: 'form-control', placeholder: 'John Doe' %> 

    <%= f.text_field :email, class: 'form-control', placeholder: 'john.doe@company.com' %> 

    <%= f.password_field :password, class: 'form-control', autocomplete: 'off', placeholder: 'Password' %> 

    <%= f.password_field :password_confirmation, class: 'form-control', autocomplete: 'off', placeholder: 'Password Confirmation' %> 

    <%= f.submit 'Sign up', class: 'btn btn-primary btn-block btn-flat' %> 

<% end %> 

My功能測試（這是目前故障）：

個

require 'rails_helper' 

RSpec.feature "User Registration", :type => :feature do 
    scenario "A new user is created" do 
    # this will cover the user profile signup info 
    visit "https://stackoverflow.com/users/sign_up" 
    fill_in "user_company_attributes_name", with: "ACME Inc." 
    fill_in "user_name", with: "Bob Jones" 
    fill_in "user_email", with: "bob@jones.com" 
    fill_in "user_password", with: "password" 
    fill_in "user_password_confirmation", with: "password" 
    click_button "Sign up" 
    expect(page).to have_text("You have signed up successfully") 
    end 
end 

的特徵測試結果：

Failures: 

    1) User Registration A new user is created 
    Failure/Error: expect(page).to have_text("You have signed up successfully") 
     expected to find text "You have signed up successfully" in "x 4 errors prohibited this user from being saved: Email can't be blankPassword can't be blankName can't be blankCompany must exist NeoUI Sign up to start getting secure can't be blank can't be blank can't be blank" 
    # ./spec/features/user_registration_spec.rb:25:in `block (2 levels) in <top (required)>' 

而只是爲了確認我試圖通過手工添加一個用戶：

我已經看過各種帖子e網絡試圖弄清楚這一點，並假設它與我在用戶表單中嵌套的company屬性有關，但仍然無法解決這個謎團。

Answer 1

我認爲設計註冊控制器創建操作不使用強參數，並沒有得到該輸入。

他們出現在請求

"user"=>{"company_attributes"=>{"name"=>"Test Company"}, "name"=>"Test User", "email"=>"test@test.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up"} 

但如果你讀你的查詢它與email = ""一個空字符串做很可能不允許作爲強大的參數，可以在事實。沒有參數正在被消毒。

WHERE "users"."email" = $1 LIMIT $2 [["email", ""], ["LIMIT", 1]] 
website_1 | [9493b284-c9dc-4832-9be9-e876feb621f4] (2.0ms) ROLLBACK 

也許你的sanitize方法寫錯了？也許你可以嘗試這樣，甚至包括他在應用程序控制器中......

def configure_permitted_parameters 
    devise_parameter_sanitizer.permit(:sign_up, keys: [:email, :name, company_attributes: [:name]]) 
end 

還與制定，我不包括在我的強烈PARAMS的:password，我看它是不是安全的，但現在我不知道。儘管我的理解標準Devise已經與:password和:password_confirmation一起工作，但是當您創建新動作時，您可能需要所有參數...

另外，它可能是您的新動作在您的強參數控制器，但創造的行動，從這個控制器仍然使用自己的強勢PARAMS
