Question

我正在使用Devise，我正在尝试允许每个用户创建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，但是一旦用户退出并重新登录，就不会进入个人资料显示页面。

换句话说 -

我可以注册新用户并将用户发送到创建个人资料页面，然后我可以使用新用户创建个人资料（我不确定个人资料是否正确保存）...我退出后签名在我收到错误：

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...

有关此问题的任何想法？

Answer 1

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

在您创建后重定向时，这不是零，因为您在此处{id} {}发送了一个ID。这转化为redirect_to @profile。当您使用/ match路径时，没有id。

因此，一个解决方案是在ProfileController的show动作中使用帮助器redirect_to profile_path(@profile)。将current_user替换为@profile = Profile.find(params[:id])。这可能会改变您所需的功能，因为它需要用户登录。这将保留数学路径（/ show url）。它起作用，因为它不再依赖于id。

您也可以将@profile = current_user.profile更改为show_path(resource.profile)。这将使用资源配置文件路径和url / profiles /：id而不是show /你可能正在寻找。

回答@Phil，我解决了项目中的另一个问题。谢谢\ o /

你的情况，我这样解决了：

在用户和个人资料模型中添加inverse_of：

<强> user.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

<强> profile.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 application_controller.rb

中

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
