Rails 3 未初始化的常量 ActiveRecord::RecordInvalid

Question

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery  

  rescue_from ActiveRecord::RecordInvalid,  :with => :error_render_method
  rescue_from ActiveRecord::RecordNotFound, :with => :record_not_found

  def error_render_method
  end

  def record_not_found
  end

end

When I run rspec I get this error:

uninitialized constant ActiveRecord::RecordInvalid (NameError)

I have googled and found that some people add require 'active_record/errors' to that file, yet when I do the error still persist.

I am using rails (3.2.9)

Answer 1

I got the same problem when I started Unicorn.

I solved it by just quoting the constant "ActiveRecord::RecordInvalid" . (Not naked constant ActiveRecord::RecordInvalid .)

I don't know the reason but it seemed like ActiveRecord::RecordInvalid hadn't loaded when starting Unicorn.

Answer 2

这似乎已在 Rails 4.0 和 4.1 之间修复。
