如何解决Rails-Devise的注册控制器create动作似乎触发了两次
我添加了以下代码行来创建动作：
def create
super
@card = Card.find(params[:card_id])
@card.update(:user_id=>current_user)
end
一切正常，创建用户，更新卡，但是在重定向之后会发生：
Couldn't find Card with 'id'=
Extracted source (around line #14):
def create
super
@card = Card.find(params[:card_id])
@card.update(:user_id=>current_user)
end
我检查了我的终端，以找出发生这种情况的原因，并且似乎create action无缘无故地触发了两次：

对此有什么解决办法吗？
编辑：我放弃了，只是更改了卡和用户逻辑，现在用户属于卡，所以我不必从设备创建动作中更新卡user_id。
解决方法
card_id嵌套在用户密钥中，因此它将是：params[:user][:card_id]
