我已经创建了Rails ActiveRecord验证,当它被违反时,没有保存任何记录(实际上,我相信它正在保存,然后在控制台输出中看到正在完成ROLLBACK)。
但是,不是再次重定向到新表单并显示我添加的错误消息,而是发送到索引页面(没有创建新记录,这是正确的,但我想要其他行为)。
我认为这是一个愚蠢的事情,与回滚相关(就像记录正在保存,这就是为什么我被重定向到索引页面,但随后回滚完成 - 不知道为什么,并且没有记录是保存)。知道如何解决这个问题吗?
我已经创建了以下验证:
# Adds an error if the replacement date is in the future
def replacement_date_is_not_future
unless replacement_date.blank? or replacement_date <= Date.today
errors.add(:replacement_date, :date)
end
end
在我的模型的头部,我有以下内容:
validate :replacement_date_is_not_future
这是我的控制器方法:
def create
@device_replacement = DeviceReplacementForm.new(replacement_params)
if @device_replacement.save
redirect_to device_replacements_path
else
render 'new'
end
end
这是我的控制台输出:

看起来你的代码很好,事情是不是在正确的地方。试着看看是否有另一个模型负责在该视图中创建device_replacement。
希望它有所帮助。
