Rails：表單不保存到數據庫，但創建方法提交時返回true

Question

我有一個簡單的博客設置與資源路由，它允許他們查看博客之前驗證用戶。我可以通過「rails c」輸入數據來「註冊」，但是當試圖提交一個表單時，它不會保存到db，「create」方法返回true，就好像它已經保存了一樣。

控制器：blogs_controller.rb

class BlogsController < ApplicationController 

    before_action :confirm_logged_in, :except => [:login, :attempt_login, :new, :logout] 

    def new 
    @user = User.new 
    end 


    def create 
    @user = User.new(message_params) 
    if @user.save! 
     redirect_to(:action => 'login') 
    else 
     render 'new' 
    end 
    end 


    def login 
    end 


    def attempt_login 
    if params[:email].present? && params[:password].present? 
     found_user = User.where(:email => params[:email]).first 
     if found_user 
     authorized_user = found_user.authenticate(params[:password]) 
     end 
    end 
    if authorized_user 
     session[:user_id] = authorized_user.id 
     session[:email] = authorized_user.email 
     redirect_to(:action => 'index') 
    else 
     redirect_to(:action => 'login') 
    end 
    end 


    def index 
    end 

    def show_month 
    @month_year = params[:month_year] 
    @year = params[:year] 
    end 

    def show_category 
    @category = params[:category] 
    end 

    def show_page 
    @date = params[:date] 
    end 

    def logout 
    session[:user_id] = nil 
    session[:email] = nil 
    flash[:notice] = "Logged out." 
    redirect_to(:action => "login") 
    end 


    private 
    def message_params 
    return params.require(:user).permit(:email, :password) 
    end 

    def confirm_logged_in 
    unless session[:user_id] 
     flash[:notice] = "Please login" 
     redirect_to(:action => 'login') 
     return false 
    else 
     return true 
    end 
    end 

end 

註冊：new.html.erb

<div class="container-fluid"> 
    <div class="row"> 
    <div class="col-xs-12"> 
     <%= form_for @user, url: blogs_path(@user) do |f| %> 
     <%= f.label :email %> 
     <%= f.text_field :email, :required => true %> 
     <br> 
     <%= f.label :password %> 
     <%= f.password_field :password, :required => true %> 
     <br> 
     <%= f.label :password_confirmation %> 
     <%= f.password_field :password_confirmation, :required => true %> 
     <br> 
     <%= f.submit("Submit")%> 
     <% end %> 
    </div> 
    </div> 
</div> 

型號：user.rb

class User < ActiveRecord::Base 
    has_secure_password 
end 

模式：schema.rb

ActiveRecord::Schema.define(version: 20151026022639) do 

    enable_extension "plpgsql" 

    create_table "messages", force: :cascade do |t| 
    t.string "name" 
    t.string "email" 
    t.string "phone_number" 
    t.string "user_message" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    create_table "users", force: :cascade do |t| 
    t.string "email" 
    t.string "password_digest" 
    t.datetime "created_at",  null: false 
    t.datetime "updated_at",  null: false 
    end 

end

Answer 1

改成這樣：

private 
def message_params 
    params.require(:user).permit(:email, :password, :password_confirmation) 
end 

Answer 2

的問題是在控制器：

before_action :confirm_logged_in, :except => [:login, :attempt_login, :new, :logout] 

我失蹤 「：打造」，這解決了問題：

要進行3210

before_action :confirm_logged_in, :except => [:login, :attempt_login, :new, :logout, :create] 

Answer 3

地段修復 - 這裏是我建議：

#config/routes.rb 
root "posts#index" 
resources :posts, only: [:index, :show] 

resources :users, only: [:new, :create], path: "", path_names: { new: "signup", create: "signup" } 
resources :sessions, only: [:new, :create, :destroy], path: "", path_names: { new: "login", create: "login", destroy: "logout" } 

這是你的控制器分割成不同的行動。

這可能看起來很複雜，但請相信我，從長遠來看，它對您的應用來說會更好。

#app/controllers/application_controller.rb 
class ApplicationController < ActionController::Base 
    #put all your application-centric logic here 
    before_action :confirm_logged_in 

    private 

    def confirm_logged_in 
     #don't need to "return" anything here 
     redirect_to new_sessions_path, notice: "Please login" unless session[:user_id] 
    end 
end 

而不是 「博客」，稱之爲 「上崗」。你的應用程序邏輯停留在應用控制器：

#app/controllers/posts_controller.rb 
class PostsController < ApplicationController 
    def index 
     @posts = Post.all 
    end 

    def show 
     @post = Post.find params[:id] 
    end 
end 

這是處理用戶會話（登錄）（偷來的form Devise）：

#app/controllers/sessions_controller.rb 
class SessionsController < ApplicationController 
    skip_before_action :confirm_logged_in 

    def new 
    end 

    def create 
     if params[:email].present? && params[:password].present? 
      if User.exists? email: params[:email] 
       authorized_user = found_user.authenticate params[:password] 
      end 
     end 
     if authorized_user 
      session[:user_id] = authorized_user.id 
      session[:email] = authorized_user.email 
      redirect_to root_path, notice: "Successful Login" 
     else 
      redirect_to :new, notice: "Sorry, there was an error" 
     end 
    end 

    def destroy 
     session.delete(:user_id) 
     session.delete(:email) 
     redirect_to new_sessions_path, notice: "Logged Out" 
    end 

end

我能夠 「註冊」通過輸入數據通過「軌道C」，但當試圖提交表格它不保存到分區

這是它應該做的事：

#app/controllers/users_controller.rb 
class UsersController < ApplicationController 
    def new 
     @user = User.new 
    end 

    def create 
     @user = User.new user_params 
     @user.save 
    end 

    private 

    def user_params 
     params.require(:user).permit(:email, :password, :other, :params) 
    end 
end 

然後您就可以使用以下幾種觀點：

#app/views/users/new.html.erb 
<%= form_for @user do |f| %> 
    <%= f.email_field :email %> 
    <%= f.password_field :password %> 
    <%= f.password_field :password_confirmation %> 
    <%= f.submit %> 
<% end %> 

- 除了

作爲，你會從受益大汗使用Devise gem。

這將基本上從您的應用程序中刪除所有session功能，包括它在Devise。這工作真的很好，我會高度推薦它。
