Question

我有一个表单设置为接受日期时间值。然后，该值将作为参数发送到我的控制器方法＆＃34; bookingdate＆＃34;它将与预订中的其他日期进行比较，以确保没有双重预订，使用do循环。

但是，当我提交日期表单时，而不是重定向到用户选择其他详细信息的下一个表单时，它会抛出错误或重定向错误。

这是我的控制器

def bookingdate

  @bookings = Booking.all
  @bookings.each do |b|
    if b.startdatetime == params[:startdatetime]
      @musicians = Musician.where (["id != ?", b.musician_id])
    end
  end

  render :action => 'new'
end

这是我的路线

match '/bookdate', :to => 'bookings#bookingdate'

添加redirect_to帮助程序并将路径传递到进度

def bookingdate

  @bookings = Booking.all
  @bookings.each do |b|
    if b.startdatetime == params[:startdatetime]
      @musicians = Musician.where (["id != ?", b.musician_id])
    end
  end

  redirect_to path_where_you_want_to_redirect
end

我想你想要执行一些检查，如果用户有正确的填写表格

def bookingdate

  @bookings = Booking.all
  @bookings.each do |b|
    if b.startdatetime == params[:startdatetime]
      @musicians = Musician.where (["id != ?", b.musician_id])
    end
  end
  if condition_successful
     redirect_to path_where_you_want_to_redirect
  else
     render :bookingdate
  end
end

在我的控制器中执行操作后如何重定向？
