使用设计添加额外的注册字段 [英] Adding extra registration fields with Devise

问题描述

我正在尝试向注册#new 添加一些额外的字段.由于我只想要额外的数据并且不需要不同的功能，我不明白为什么我需要覆盖控制器等.所以我所做的是修改 registrations#new 如下:

I am trying to add some extra fields to registrations#new. Since I only want extra data and do not need different functionality, I don't see why I need to override controllers etc. So what I did was modify registrations#new as follows:

%h2
  Sign up
= 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
    = f.label :title_id
    %br
    = f.text_field :title_id
  %div
    = f.label :province_id
    %br
    = f.text_field :province_id
  %div
    = f.label :first_name
    %br
    = f.text_field :first_name
  %div
    = f.label :last_name
    %br
    = f.text_field :last_name
  %div
    = f.label :password
    %br
    = f.password_field :password
  %div
    = f.label :password_confirmation
    %br
    = f.password_field :password_confirmation
  %div= f.submit 'Sign up'
= render 'devise/shared/links'

为了通过 sanitizer 启用这些额外的字段，我更新了 ApplicationController 如下:

To enable these extra fields through the sanitizer, I updated ApplicationController as follows:

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
  before_filter :store_requested_url!
  # before_filter :authenticate_user!

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email) }
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password, :password_confirmation, :title_id, :province_id, :first_name, :last_name) }
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:email, :password, :password_confirmation, :current_password) }
  end

  def after_sign_in_path_for(resource)
    session[:requested_url] || root_path
  end

  private

  def store_requested_url
    # store last url as long as it isn't a /users path
    session[:previous_url] = request.fullpath unless request.fullpath == //users/
  end
end

由于某种原因，它不起作用，额外的字段作为空值进入数据库.

For some reason, it is not working and the extra fields go to the database as nulls.

我正在使用 Ruby 2 和 Rails 4 rc1，以及 Devise 3.0.0.rc.

推荐答案

好的，所以我所做的只是覆盖设计注册控制器，根据设计文档更新 routes.rb 以反映这一点，复制并粘贴设计代码对于注册#create 原样，并将获取参数部分更改为使用我自己的强参数方法，就是这样.

OK, so what I did was just override the Devise registration controller, update routes.rb as per the devise docs to reflect this, copied and pasted the Devise code for registrations#create as is, and change the getting params part to use my own strong parameters method, and that was that.

class RegistrationsController < Devise::RegistrationsController

  def create
    build_resource(registration_params)

    if resource.save
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_up(resource_name, resource)
        respond_with resource, :location => after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
        respond_with resource, :location => after_sign_up_path_for(resource)
      end
    else
      clean_up_passwords
      respond_with resource
    end
  end  

  private

  def registration_params
    params.require(:user).permit(:email, :title_id, :first_name, :last_name, 
      :province_id, :password, :password_confirmation)
  end

end
