Question

我想在创建新用户时使用@value = SecureRandom.base64（8）设置密码字段。当我编辑用户时，我不希望它发生。所以我的问题是我在哪里使用users_controller.rb中的SecureRandom.base64（8）或者models / user.rb

这是users_controller.rb

def create
    if user.save
      user.send_invitation
      redirect_to root_url, notice: "Signed up!"
    else
      render :new
    end
  end

  def destroy
    @user = User.find(params[:id])

    if @user.destroy
        redirect_to root_url, notice: "User was deleted successfully!"
    end
  end

  def edit
    respond_with(user)
  end

  def update
    @user.password_confirmation = User.value
    params[:user].delete(:password) if params[:user][:password].blank?
    params[:user].delete(:password_confirmation) if params[:user][:password_confirmation].blank?
    if user.save
      redirect_to users_path, :notice => "Saved your updates!"
    else
      render :edit
    end
  end

使用before_create回调：

class User < ActiveRecord::Base
  before_create :create_password

  private
  def create_password
    self.password = SecureRandom.base64(8)
  end
end

使用Rails创建新用户时创建随机密码
