范围未指定.指定:in,:within,:maximum,:minimum或:是选项

Question

我添加了验证我的模型"entrada":

class Entrada < ActiveRecord::Base
  validates :titulo, presence: true,
            length: { minimun: 5 }

  attr_accessible :entrada, :titulo
end

所以我得到以下错误:

Range unspecified. Specify the :in, :within, :maximum, :minimum, or :is option.

Answer 1

看起来你拼错了minimum.
