Rails控制台：重新加载！没有反映模型文件中的更改？可能是什么原因？ [英] Rails Console: reload! not reflecting changes in model files? What could be possible reason?

问题描述

之前，它工作正常。我一直在玩一些配置。所以可能是我在不知不觉中更改了一些配置。

Earlier it was working fine. I have been playing little bit config. So may be i have changed some config unknowingly.

这是environment / development.rb的配置。

here is config of environment/development.rb

  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_view.debug_rjs             = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # migration prefix with sequence #s
  config.active_record.timestamped_migrations = false

  #time zone
  config.time_zone = 'UTC'

这是application的配置部分.rb

Here is config section of application.rb

 # Configure the default encoding used in templates for Ruby 1.9.
 config.encoding = "utf-8"

 # Configure sensitive parameters which will be filtered from the log file.
 config.filter_parameters += [:password]

 config.active_record.schema_format = :sql

当我重新加载时！在Rails控制台上，它返回true

when i run reload! on rails console it return true

推荐答案

重新加载！仅重新加载最新的控制台环境中的代码。不会重新初始化现有对象。

reload! only reloads the latest code in the console environment. It does not re-initialize existing objects.

这意味着如果您已经实例化了任何对象，它们的属性将不会更新-包括新引入的验证。但是，如果您创建一个新对象，则其属性（以及验证）将反映重新加载的代码。

This means if you have already instantiated any objects, their attributes would not be updated - including newly introduced validations. However, if you create a new object, its attributes (and also validations) will reflect the reloaded code. more here
