如何使用Devise为用户注册其他属性？

Question

我正在使用Devise,我有一个User模型.默认情况下,只有一个包含电子邮件和密码的注册表单.我想添加更多属性.例如college属性.

我一直关注这篇博客文章来帮忙.我有一个RegistrationsController覆盖默认值RegistrationsController:

class MyDevise::RegistrationsController < Devise::RegistrationsController
  def create
    super
    resource.college = params[:resource][:college]
    resource.save
  end
end

但是,我不知道如何更新用户.我一直在寻找Devise的RegistrationController,但我似乎无法弄明白.它是否无法访问params[:resource]表单？

这是视图文件中的表单:

<h2>Sign up</h2>

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

  <div><%= f.label :email %><br />
  <%= f.email_field :email, autofocus: true %></div>

  <div><%= f.label :password %><br />
    <%= f.password_field :password, autocomplete: "off" %></div>

  <div><%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation, autocomplete: "off" %></div>

  <div><%= f.label :college %><br />
    <%= f.text_field :college %></div>
<% end %>

<%= render "devise/shared/links" %>

看一下RailsApps项目中的Rails和Devise示例应用程序.例如,要向nameUser模型添加属性:

您可以使用生成器创建迁移.

迁移:

# db/migrate/..._add_name_to_users.rb
class AddNameToUsers < ActiveRecord::Migration
  def change
    add_column :users, :name, :string
  end
end

您需要覆盖Devise控制器以处理Rails 4.0(和更新版本)中的强参数.

控制器:

# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
  before_filter :update_sanitized_params, if: :devise_controller?

  def update_sanitized_params
    devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:name, :email, :password, :password_confirmation)}
    devise_parameter_sanitizer.for(:account_update) {|u| u.permit(:name, :email, :password, :password_confirmation, :current_password)}
  end

end

表格:

# app/views/devise/registrations/new.html.erb
<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>
<p><%= f.label :name %><br />
<%= f.text_field :name %></p>

  <div><%= f.label :email %><br />
  <%= f.email_field :email %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <div><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></div>

  <div><%= f.submit "Sign up" %></div>
<% end %>

<%= render "devise/shared/links" %>

调整路径以适应新控制器.

路线:

# config/routes.rb
RailsDevise::Application.routes.draw do
  root :to => "home#index"
  devise_for :users, :controllers => {:registrations => "registrations"}
  resources :users
end
