PostgreSQLactive weirdness for .maximum
原标题:PostgreSQL activerecord weirdness for .maximum

我有一份积极记录<代码>,在_save之前。 造成奇迹错误的方法:

class MyThing < ActiveRecord::Base
  before_save :dostuff

  def dostuff
    p self.class.maximum(:mycolumn)
  end
end

当我使用Kingh时,这种工作是完美的,现在是用 post子进行的。 我发现错误:

PGError: ERROR: current transaction is aborted, commands ignored until end of transaction block : SHOW max_identifier_length

<代码>.maximum 方法在dostuff方法之外运行,因此,我猜测I m只是一度要求过多? 是否有另一种办法获得将在<条码>之前在<条码>内工作的立体字体的最大值?

最佳回答

错误涉及最高标准——识别器——宽度,物体名称的最长期限(表、栏等)。 它与Call-Sex公司毫无关系。 你们喜欢改用一个无效的名称,这个名称超过63个。
