2 个解决方案

#1

Change this line:

改变这条线:

@reservation = Reservation.new(params[:reservation_params])

to:

@reservation = Reservation.new( reservation_params )

#2

you have the problem in this line

这条线上有问题

@reservation = Reservation.new(params[:reservation_params])

the thing is that if you see in your controller you have a method that just permit some params for security that is "reservation_params"

如果你在你的控制器中看到你有一个方法它只允许一些安全参数的参数就是"reservation_params"

so you just need to change the line for this

你只需要改变这条线

@reservation = Reservation.new(reservation_params)

and it just works.
