Ruby on rails 带一些参数的Running rails runner
这个命令是我的问题:Ruby on rails 带一些参数的Running rails runner,ruby-on-rails,ruby,linux,bash,command-line,Ruby On Rails,Ruby,Linux,Bash,Command Line,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”作为其参数,它应
/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”作为其参数,它应该是script/runner的参数。我想这可以用括号来解决,但我不知道 如果这个解决方案不涉及(或依赖)Rails或Linux的全局环境,它会更好

不需要文件路径,而是需要一些Ruby来执行:
script/runner "MyClass.do_something('my_arg')"
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,最好将其编写为Rake任务。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
您可以通过以下方式执行此操作:
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
也可以。我假设您使用的是基于
script/runner
的较旧Rails,我不知道这是否适用于较旧的Rails,但在较新的Rails中,您只需要求“config/environment”
,它就会加载应用程序。然后你就可以在那里写脚本了
例如,我有一个脚本,它接受一个参数,如果提供了参数,则将其打印出来,然后打印出我的应用程序中有多少用户:
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
不带参数调用:
$ be ruby app/jobs/my_job.rb
THERE ARE 2 USERS
使用arg速记呼叫:
$ be ruby app/jobs/my_job.rb -t my_arg
THE ARGUMENT WAS "my_arg"
THERE ARE 2 USERS
用arg长手呼叫:
$ be ruby app/jobs/my_job.rb --the-arg my_arg
THE ARGUMENT WAS "my_arg"
THERE ARE 2 USERS
