ruby-on-rails - Rails rake 'Don' t 知道如何构建任务'

Question

我正在尝试使用多个参数在终端中运行我的 rake 任务，但是我不断收到错误消息:

rake populate:user['a' 'a'] 
DL is deprecated, please use Fiddle
rake aborted!
Don't know how to build task 'populate:user[a'

我的 rake 文件:

namespace :populate do
  desc 'Populate data into our database'

  task :user, [:username, :password] => :environment do |t, args|
    // do stuff, also doesn't work when I delete everything inside here
  end
end

我也试过

rake populate:user[a, a] 

它确实在没有任何参数的情况下运行:

rake populate:user

Answer 1

你可以试试

rake 'populate:user[a,a]'
