最佳答案
有以下代码:
class Product < ActiveRecord::Base
validates :title, :description, :image_url, presence: true
validates :price, numericality: {greater_than_or_equal_to: 0.01}
validates :title, uniqueness: true
validates :image_url, allow_blank: true, format: {
with: %r{\.(gif|jpg|png)$}i,
message: 'URL must point to GIT/JPG/PNG pictures'
}
end
它可以工作,但是当我尝试使用“ rake test”测试它时,我会捕捉到以下信息:
rake aborted!
The provided regular expression is using multiline anchors (^ or $), which may present a security risk. Did you mean to use \A and \z, or forgot to add the :multiline => true option?
这是什么意思? 我该怎么补救?
