我正在使用设计并试图允许每个用户创建 1 个配置文件。我可以将新注册的用户发送到他们可以创建个人资料的页面，但是一旦用户注销并重新登录，它将不会进入个人资料显示页面。

换句话说-

我可以注册一个新用户并将用户发送到创建配置文件页面，然后我可以使用新用户创建一个配置文件（我不确定配置文件是否正确保存）......在我注销并登录后，我收到了错误：

ActiveRecord::RecordNotFound in ProfilesController#show

Couldn't find Profile without an ID

我希望将用户发送到他们的个人资料显示页面...

对这个问题有什么想法吗？

代码（按文件排序）如下……</p>

用户.rb

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

  attr_accessible :email, :password, :password_confirmation, :remember_me

 has_one :profile
end

配置文件.rb

class Profile < ActiveRecord::Base
 attr_accessible :first_name, :last_name

 belongs_to :user

end

profile_controller.rb

class ProfilesController < ApplicationController
 # GET /profiles
 # GET /profiles.json
def index
 @profiles = Profile.all

respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @profiles }
 end
end

# GET /profiles/1
# GET /profiles/1.json
def show
 @profile = Profile.find(params[:id])

 respond_to do |format|
  format.html # show.html.erb
  format.json { render json: @profile }
 end
end

# GET /profiles/new
# GET /profiles/new.json
def new
 @profile = Profile.new

 respond_to do |format|
  format.html # new.html.erb
  format.json { render json: @profile }
 end
end

# GET /profiles/1/edit
def edit
 @profile = Profile.find(params[:id])
end

# POST /profiles
# POST /profiles.json
def create
  @profile = Profile.new(params[:profile])

respond_to do |format|
  if @profile.save
    format.html { redirect_to @profile, notice: 'Profile was successfully created.' }
    format.json { render json: @profile, status: :created, location: @profile }
  else
    format.html { render action: "new" }
    format.json { render json: @profile.errors, status: :unprocessable_entity }
  end
 end
end

# PUT /profiles/1
# PUT /profiles/1.json
def update
 @profile = Profile.find(params[:id])

 respond_to do |format|
   if @profile.update_attributes(params[:profile])
     format.html { redirect_to @profile, notice: 'Profile was successfully updated.' }
     format.json { head :no_content }
   else
     format.html { render action: "edit" }
     format.json { render json: @profile.errors, status: :unprocessable_entity }
   end
 end
end

# DELETE /profiles/1
# DELETE /profiles/1.json
def destroy
  @profile = Profile.find(params[:id])
  @profile.destroy

  respond_to do |format|
    format.html { redirect_to profiles_url }
    format.json { head :no_content }
  end
 end
end

注册控制器.rb

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    request.env['omniauth.origin'] || stored_location_for(resource) || new_profile_path
  end
end

application_controller.rb

class ApplicationController < ActionController::Base
  def after_sign_in_path_for(resource)
    request.env['omniauth.origin'] || stored_location_for(resource) || show_path(resource.profile)
  end
end

路线.rb

BaseApp::Application.routes.draw do
  resources :profiles

  get "users/show"

  devise_for :users, :controllers => { :registrations => "registrations" }
  resources :users

  match '/show', to: 'profiles#show'


  match '/signup',  to: 'users#new'

  root to: 'static_pages#home'

  match '/', to: 'static_pages#home'

  …

在您的控制器中，您使用以下代码@profile = Profile.find(params[:id])。登录时params[:id]必须为零。

创建后重定向时它不是 nil ，因为您在这里发送了一个 id redirect_to @profile。这转化为redirect_to profile_path(@profile). 当您使用 /match 路径时，没有 id。

因此，一种解决方案是current_user在 ProfileController 的显示操作中使用帮助程序。替换@profile = Profile.find(params[:id])为@profile = current_user.profile。这可能会改变您想要的功能，因为它需要用户登录。这将保留数学路径（/show url）。它之所以有效，是因为它不再依赖于 id。

您也可以将 更改show_path(resource.profile)为profile_path(resource.profile)。这将使用带有 URL /profiles/:id 的资源配置文件路径，而不是您可能正在寻找的 show/。

通过@Phil 提供的答案，我解决了项目中的另一个问题。谢谢\o/

  • ruby 2.0.0p247（2013-06-27 修订版 41674）[x86_64-linux]
  • 导轨 4.0.0

而你的情况，我是这样解决的：

在用户和配置文件模型中添加 inverse_of:

用户.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
       :recoverable, :rememberable, :trackable, :validatable

  has_one :profile, inverse_of: :user
end

配置文件.rb

class Profile < ActiveRecord::Base
  belongs_to :user, inverse_of: :profile
  validates :first_name, :user_id, :presence => true
  validates :gender, :inclusion => {:in => %w(M F)}

end

在你的application_controller.rb

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  # redirect user after login
  def after_sign_in_path_for(resource)
    unless current_user.profile.nil?
      profiles_path 
    else
      flash[:alert] = "Please complete your profile"
      new_profile_path
    end
  end

  # redirect after logout
  def after_sign_out_path_for(resource_or_scope)
    new_user_session_path
  end

end

这对我有用，我希望这有帮助
