将：staging组添加到My Gemfile的正确方法是什么？

I have remotes set up on Heroku for production and staging.

我在Heroku上设置遥控器进行制作和舞台演出。

On staging I have set the app's envs to include:

在暂存时,我已将应用程序的env设置为包括:

RACK_ENV=staging
RAILS_ENV=staging

I would like to be able to specify a staging group in my Gemfile in the same way I can currently use production, test or assets:

我希望能够在我的Gemfile中指定一个临时组,就像我目前使用生产,测试或资产一样:

group :staging do
  gem "example", "~> 0.9"
end

I understand how to add custom groups. From my application.rb:

我了解如何添加自定义组。从我的application.rb:

  groups = {
    assets: %w(development test)
  }
  Bundler.require(:security, :model, :view, *Rails.groups(groups))

But how do I add a group that is only loaded in staging?

但是,如何添加仅在分段中加载的组?

I've tried without success:

我试过没有成功:

  groups = {
    assets: %w(development test),
    staging: %(staging)
  }
  Bundler.require(:security, :model, :view, *Rails.groups(groups))

Your Gemfile could include a group as follows:

您的Gemfile可以包含如下组:

# Gemfile
  group :staging do
    gem 'example','~>1.0'
  end

Create an environment for staging

为登台创建环境

# /config/environments/staging.rb
... 
copy config/environments/production.rb code here with adjustments as needed
...

The reason this works is found in /config/application.rb.

其工作原理可在/config/application.rb中找到。

Rails.groups includes the :default group (all ungrouped gems) and the gem group matching the name of the environment, set by RAILS_ENV, which in this case would be "staging". Your require. Your Bundler.require should look like:

Rails.groups包括:默认组(所有未组合的gems)和与RAILS_ENV设置的环境名称匹配的gem组,在本例中为“staging”。你的要求。您的Bundler.require应如下所示:

Bundler.require *Rails.groups(:assets => %w(development test))
