很抱歉，但我已经有40个小时的时间来解决这个问题，（我是新手）我已经回顾了与此错误相关的类似问题，但未能找到解决方案。
我有一个拥有员工的分支模型，那些员工有出勤，所以当我想保存员工的出勤时我得到了这个错误： https://s3.amazonaws.com/refaccionariasdelvalle/rails-error.png

我认为问题在于我将布尔：present 的值传递给数据库，但如果是这样，我还是不知道如何使其工作。
感谢您的帮助！
更新
首先，感谢@Sebastían，@ Gerry和@Pavan感兴趣帮助我。
现在，这是如何在控制台上运行而不是从应用程序运行？

在从控制台创建这些记录之后，我可以转到应用程序并对这些记录进行更新并且工作正常。 但是，如果我去控制台并删除之前创建的那两个最后记录，使其再次出现以标记应用程序中的出席我得到相同的错误：
ArgumentError in AttendancesController#create
wrong number of arguments (given 0, expected 1)
Extracted source (around line #81):
81: def attendance_params(my_params)
82: my_params.permit(:present, :employee_id)
83: end
我真的不明白
答案 0 :(得分：2)
strong_params不接受争论。您可以根据需要标记一个哈希值，该哈希值将通过您的参数传递给您的控制器并在那里指定允许的密钥。
所以，相反，定义attendance_params期望一个名为my_params的参数，那么你可以把它变成一个“非参数”方法，而不是使用my_params，然后使用params实例公共方法，该方法将返回一个新的ActionController::Parameters对象，该对象使用request.parameters初始化。
您可以尝试：
def attendance_params
params.permit(:present, :employee_id)
end
