这个命令是我的问题:
/usr/local/bin/ruby **script/runner** --environment=production app/jobs/**my_job.rb** -t my_arg
`my_job.rb` is my script, which handles command line arguments. In this case it is `-t my_arg`.
my_job.rb
也将`--environment = production'作为参数,这应该是script / runner的参数。
我想这可以用一些括号来解决,但没有想法。
如果解决方案没有触及(或依赖于)Rails或Linux的全球环境,那就更好了。

script/runner
不会获取文件的路径,而是需要执行一些Ruby:
script/runner "MyClass.do_something('my_arg')"
您始终可以使用环境变量设置Rails环境,例如:
RAILS_ENV=production script/runner "MyClass.do_something('my_arg')"
如果您想运行一些复杂的任务,最好将其作为Rake任务编写。例如,您可以创建文件lib/tasks/foo.rake
:
namespace :foo do
desc 'Here is a description of my task'
task :bar => :environment do
# Your code here
end
end
您可以执行以下操作:
rake foo:bar
与script/runner
一样,您可以使用环境变量设置环境:
RAILS_ENV=production rake foo:bar

我假设您使用的是基于script/runner
的旧版Rails,我不知道这是否适用于较旧的Rails,但是在较新的Rails中,您只能require 'config/environment'
,而它将加载该应用程序。然后你可以在那里编写脚本。
例如,我有一个接受参数的脚本,如果提供了参数,则将其打印出来,然后打印出我的应用中有多少用户:
文件:app / jobs / my_job.rb
require 'optparse'
parser = OptionParser.new do |options|
options.on '-t', '--the-arg SOME_ARG', 'Shows that we can take an arg' do |arg|
puts "THE ARGUMENT WAS #{arg.inspect}"
end
end
parser.parse! ARGV
require_relative '../../config/environment'
puts "THERE ARE #{User.count} USERS" # I have a users model
没有args调用:
$ be ruby app/jobs/my_job.rb
THERE ARE 2 USERS
使用arg简写调用:
$ be ruby app/jobs/my_job.rb -t my_arg
THE ARGUMENT WAS "my_arg"
THERE ARE 2 USERS
用arg长手打电话:
$ be ruby app/jobs/my_job.rb --the-arg my_arg
THE ARGUMENT WAS "my_arg"
THERE ARE 2 USERS
