只是让仪器不打印出来这将是有用的.
我正在使用 VS Code,并认为固定选项卡将保留在其固定位置(它是左上角的选项卡)。

我如何将其固定到位?
我正在尝试将参数传递给Rake任务并访问我的模型,如" 如何将命令行参数传递给rake任务 "和" 执行rails rake任务提供对ActiveRecord模型的访问权限? "中所述.
但是添加=> :environment到此代码:
require 'rake'
namespace :genre do
desc "Add a genre"
task :add, :genre_id, :name => :environment do |t, args|
puts args.name
end
end

运行任务时给我这个错误:
rake genre:add['1','Abc']
rake aborted!
undefined method `map' for :name:Symbol
(See full trace by running task with --trace)

如果我删除=> :environment它就可以了.
