我希望在用户注册时发送一封电子邮件。此电子邮件应包含将帐户更改为完整用户的链接。我希望此电子邮件链接成为安全令牌。
- email_token 是每个用户随机生成的令牌
- email_activation_token 是一个布尔值,表示用户是否完成注册
目前:我收到要发送的电子邮件,但是当我单击链接时出现此错误。
ActiveRecord::RecordNotFound in UsersController#accept_invitation
Couldn't find User without an ID
链接已发送 http://localhost:3000/users/accept_invitation.P3Iu5-21nlISmdu2TlQ08w

@user = User.find(params[:email_token])
@user.email_activation_token = true
redirect_to root_url, :notice => "Email has been verified."
