本文介绍了Ruby on Rails的：延长的ActiveRecord ::错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在Ruby on Rails的，哪里有人所说的code这段代码中的http：//依据。 github/376389 ？我想的ActiveRecord ::错误延伸与code，它是可有这样我就可以合并的错误消息。

这是不是对的ApplicationController？或LIB？

解决方案

您可以直接丢弃到你的初始化目录中的任何ruby文件（创建一个新的，名称任何你想要的）。轨运行的所有文件有每次启动时的时间，并会延长错误在那个时候。

In Ruby on Rails, where does one put the code from this snippet in gist.github/376389? I want to extend ActiveRecord::Errors with the code that's available there so I can merge error messages.

Is this something for ApplicationController? or for lib?

Paste from github

# monkey patch gleaned from dev.rubyonrails/attachment/ticket/11394/merge_bang_errors.patch module ActiveRecord class Errors def merge!(errors, options={}) fields_to_merge = if only=options[:only] only elsif except=options[:except] except = [except] unless except.is_a?(Array) except.map!(&:to_sym) errors.entries.map(&:first).select do |field| !except.include?(field.to_sym) end else errors.entries.map(&:first) end fields_to_merge = [fields_to_merge] unless fields_to_merge.is_a?(Array) fields_to_merge.map!(&:to_sym) errors.entries.each do |field, msg| add field, msg if fields_to_merge.include?(field.to_sym) end end end end

解决方案

You can just drop that into any ruby file in your initializers directory (create a new one, name it whatever you want). Rails runs all of the files in there every time it is booted, and will extend Errors at that time.
