第一步，重写 users_controller.rb

class Clearance::UsersController < ApplicationController  skip_before_filter :authorize, only: [:create, :new]  before_filter :avoid_sign_in, only: [:create, :new], if: :signed_in?  def new    @user = user_from_params    render template: 'users/new'  end  def create    @user = user_from_params    if @user.save      sign_in @user      redirect_back_or url_after_create    else      render template: 'users/new'    end  end  def edit  	@user = current_user    render template: 'users/edit'  end  def update  	@user = current_user  	@user.password = params[:user][:password]  	@user.weixin_sk = params[:user][:weixin_sk]  	@user.weixin_ak = params[:user][:weixin_ak]  	    if @user.save      redirect_back_or url_after_create    else      render template: 'users/edit'    end  end  private  def avoid_sign_in    redirect_to Clearance.configuration.redirect_url  end  def url_after_create    Clearance.configuration.redirect_url  end  def user_from_params    user_params = params[:user] || Hash.new    email = user_params.delete(:email)    password = user_params.delete(:password)    weixin_ak = user_params.delete(:weixin_ak)    weixin_sk = user_params.delete(:weixin_sk)    Clearance.configuration.user_model.new(user_params).tap do |user|      user.email = email      user.password = password      user.weixin_ak = weixin_ak      user.weixin_sk = weixin_sk    end  end #  def permit_params	#   params.require(:user).permit(:weixin_ak,:weixin_sk, :email, :password)	# endend
