执行db:test:从另一个rake任务中准备

Question

我正试图rake db:test:prepare从另一个任务执行.

namespace :db do
  namespace :populate do
    desc "Seed development database"
    task development: :environment do
      puts "Kill local server"
      %x{ ps xauwww | grep -i --regex="[t]hin" | awk '{print $2}' | xargs kill }
      puts "Resetting development database"
      Rake::Task['db:reset'].execute
      puts "Migrating development database"
      Rake::Task['db:migrate'].execute
      puts "Populating development database"
      Rake::Task['db:populate'].execute
      puts "Pepare test database"
      Rake::Task['db:test:prepare'].execute
      puts "Start local server"
      system 'thin -d start'
    end
   …
end

使用invoke而不是execute无济于事.如果我自己定义它似乎工作正常:

task example: :environment do
  Rake::Task['db:test:prepare'].execute
end

当我运行时rake db:populate:development,所有任务都在运行,除了Rake::Task['db:test:prepare'].execute.该命令的开发日志中没有活动,但它不会阻止下一个任务运行(启动服务器).通常,当我单独运行时,我会看到一些SQL语句db:test:prepare.

尝试Rake::Task['db:test:prepare'].invoke代替.execute，以便它首先运行相关任务。但它仅在未首先调用该任务的情况下调用该任务。
