標題[問題] count的使用
時間Fri Oct 12 22:48:51 2007
最近想要寫一個程式，
def create
@record = Record.new(params[:record])
if Record.count(:conditions => "seatnumber = @record.seatnumber") == 0
@record.punishment = "無"
elsif Record.count(:conditions => "seatnumber = @record.seatnumber") == 1
@record.punishment = "週末輔導"
else
@record.punishment = "警告乙支"
end
if @record.save
flash[:notice] = '紀錄新增成功！'
redirect_to :action => 'list'
else
render :action => 'new'
end
end
但是在if Record.count(:conditions => "seatnumber = @record.seatnumber") == 0
這行中，@record.seatnumber沒辦法換成form上的資料，是不是有別種寫法才對？
謝謝！
