Rake：如何将参数转发给子 Rake 调用？

因此，在我的 rake 命令中，当我执行 --trace 时，它仅在我手动执行的命令上执行，而不会在自定义 rake 执行的 rake 命令上执行。

我的 Rake 命令：

namespace :db do
  task :regenesis do
    #because of how devestating this command could be, it's going 
    # to be forced to use the Test Environment
    puts "Re-Generating the Database"
    Rake::Task["db:drop RAILS_ENV=test --trace"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:bootstrap RAILS_ENV=test"].invoke
  end
end

理想的是不必在其中硬编码 --trace =D

因此，我应该能够执行 rake db:regenesis --trace，并且它应该将跟踪附加到所有这些 rake 命令上。

我该怎么做？

原文

So, in my rake command, when I do --trace, it only does it on the command I manually execute, and none of the rake commands that the custom rake executes.

My Rake command:

namespace :db do
  task :regenesis do
    #because of how devestating this command could be, it's going 
    # to be forced to use the Test Environment
    puts "Re-Generating the Database"
    Rake::Task["db:drop RAILS_ENV=test --trace"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:bootstrap RAILS_ENV=test"].invoke
  end
end

Twould be ideal to not have to hard code the --trace in there =D

So, I should be able to do rake db:regenesis --trace, and it should append trace onto all of those rake commands.

How do I do that?

请检查此问题。如果您无法修改任务以添加参数（由于某种原因），那么您可以使用环境变量，例如：

namespace :db do
  task :regenesis do
    #because of how devestating this command could be, it's going 
    # to be forced to use the Test Environment
    puts "Re-Generating the Database"
    ENV["extra_option"] = "--trace"
    Rake::Task["db:drop RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:bootstrap RAILS_ENV=test"].invoke
  end
end

在您的任务中，您必须查找 ENV["extra_option"]

Please check this question. If you cannot modify your tasks to add the parameters ( for some reason ), then you can use environment variables, like:

namespace :db do
  task :regenesis do
    #because of how devestating this command could be, it's going 
    # to be forced to use the Test Environment
    puts "Re-Generating the Database"
    ENV["extra_option"] = "--trace"
    Rake::Task["db:drop RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:create RAILS_ENV=test"].invoke
    Rake::Task["db:bootstrap RAILS_ENV=test"].invoke
  end
end

And in your tasks you'd have to look for ENV["extra_option"]
