【问题描述】:
任何正常更改后都不需要重新启动 Rails 服务器。但是,当我对我的应用程序控制器进行少量更改时,如果我不重新启动服务器,它们就不会应用。即使我写了错误的代码并故意犯了错误,旧的错误仍然存在。如何更改或验证设置是否正确?
我在config/environment/development.rb file:
config.cache_classes = false
This 对我不起作用。
UDPATE 1:
开发.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Do not eager load code on boot.
config.eager_load = false
# Show full error reports and disable caching.
config.consider_all_requests_local = 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
# Raise an error on page load if there are pending migrations.
config.active_record.migration_error = :page_load
# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true
# Asset digests allow you to set far-future HTTP expiration dates on all assets,
# yet still be able to expire them through the digest params.
config.assets.digest = true
# Adds additional error checking when serving assets at runtime.
# Checks for improperly declared sprockets dependencies.
# Raises helpful error messages.
config.assets.raise_runtime_errors = true
# Raises error for missing translations
# config.action_view.raise_on_missing_translations = true
end
【问题讨论】:
-
使用哪个命令来启动 Rails 服务器并共享您的 development.rb 文件内容并在您的终端
export RAILS_ENV=development中尝试此操作,然后重新启动您的 Rails 服务器。 -
我使用:“rails s”来启动我的服务器。我在哪里尝试这个:“export RAILS_ENV=development”?在根应用程序文件夹内还是在任何地方?
-
只需将其放入您想要启动控制台的用户的 ~/.bashrc 或 ~/.bash_profile 文件中,或者直接在终端中运行它即可。
-
对不起,我在 Windows 7 上运行它。当我启动服务器时,它显示:“development”。
-
每当我不得不使用 Rails 时,我从来没有遇到过这个问题。 (我在 Mac 上)。你用的是什么版本的 Rails?可能有一个专门影响 Windows 的错误。
