你在哪里存储你的Rails应用程序版本号？

Posted 2023-01-06

在对rails应用程序进行版本控制时，我们使用了精彩的semantic versioning范例。我遇到的一个问题是，最好存储这个号码？我已经看到它存储在/lib，environment.rb等。

只是想知道人们对最佳实践的看法？

答案

我真的不认为这有任何约定。我想这都是关于你看起来很自然的事情。

可以放置版本号的一些地方是：

• config/environment.rb
• config/application.rb
• config/initializers/version.rb

通过增加：

VERSION = '1.0.0'

无论您选择哪个选项（从上面） - VERSION常量将在应用程序的初始化时设置。

对于我的博客，我只更新布局的页脚 - 因为其他地方没有使用版本号。

lib文件夹确实听起来有点奇怪，因为这个文件夹用于存储可重用的模块。

另一答案

我的策略是让你的VCS标签为你做（这里显示的是git）。

将此添加到您的application.rb：

# Only attempt update on local machine
if Rails.env.development?
  # Update version file from latest git tag
  File.open('config/version', 'w') do |file|
    file.write `git describe --tags --always` # or equivalent
  end
end

config.version = File.read('config/version')

然后，您可以使用Rails.configuration.version访问应用中任意位置的版本

另一答案

我的偏好是创建一个生成的rake任务

# config/initializers/version.rb
VERSION = ["1", "0", "f3d9da7"]

FWIW，我的佣金任务：

task :create_version do
  desc "create VERSION.  Use MAJOR_VERSION, MINOR_VERSION, BUILD_VERSION to override defaults"

  version_file = "#Rails.root/config/initializers/version.rb"
  major = ENV["MAJOR_VERSION"] || 1
  minor = ENV["MINOR_VERSION"] || 0
  build = ENV["BUILD_VERSION"] || `git describe --always --tags`
  version_string = "VERSION = #[major.to_s, minor.to_s, build.strip]\n"
  File.open(version_file, "w") |f| f.print(version_string)
  $stderr.print(version_string)
end

另一答案

使用rake任务通过rake进行自动化控制，例如：qazxsw poi

然后在config / initializers / version.rb中：模块SiteInfo类应用程序

另一答案

我个人更喜欢在应用程序类中添加一个常量。

def self.version
  "v#self.read_version"
end

def self.read_version
  begin
    File.read 'VERSION'
  rescue
    raise "VERSION file not found or unreadable."
  end
end

另一答案

在Rails 4中，@ fearless_fool上面的rake任务需要看起来像这样：

# file: config/initializers/version.rb
class SomeApp::Application
  Version = '1.0.0'
end

desc "create VERSION. Use MAJOR_VERSION, MINOR_VERSION, BUILD_VERSION to override defaults" task :create_version do version_file = "#Rails.root/config/initializers/version.rb" major = ENV["MAJOR_VERSION"] || 1 minor = ENV["MINOR_VERSION"] || 0 build = ENV["BUILD_VERSION"] || `git describe --always --tags` version_string = "VERSION = #[major.to_s, minor.to_s, build.strip]\n" File.open(version_file, "w") |f| f.print(version_string) $stderr.print(version_string) end 线必须存在并且必须在desc线之前，以便耙子识别它。

另一答案

version.rake

task :create...

另一答案

我们可以使用qazxsw poi并使用qazxsw poi创建初始化器来设置应用程序版本

Add the def valid? version pattern = /^\d+\.\d+\.\d+(\-(dev|beta|rc\d+))?$/ raise "Tried to set invalid version: #version".red unless version =~ pattern end def correct_version version ver, flag = version.split '-' v = ver.split '.'

git gem

别忘了运行git describe。

Create a new initializer file.

git

现在我们可以访问这样的版本：

# Gemfile
# ...
group :development do
  gem 'git'
  # ...
end
