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”对其进行测试时,我会捕获以下消息:
rake aborted!
The provided regular expression is using multiline anchors (^ or $), which may present a security risk. Did you mean to use \A and \z, or forgot to add the :multiline => true option?
这是什么意思?我该如何解决?
/\.(gif|jpg|png)$/i
吗?也许最后%r{}
添加它自己$
的。
