我有一个rake任务需要将值插入多个数据库.

我想从命令行或另一个 rake任务将此值传递给rake任务.

我怎样才能做到这一点？

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.

更新:

跟踪:

rake --trace genre:add['1','Abc']
rake aborted!
undefined method `map' for :name:Symbol
