如何构建任务 'generate_secret_token'

Question

我在运行:

时遇到此错误

rake generate_secret_token

rake aborted!
Don't know how to build task 'generate_secret_token'
/usr/local/rvm/gems/ruby-2.1.3/bin/ruby_executable_hooks:15:in `eval'
/usr/local/rvm/gems/ruby-2.1.3/bin/ruby_executable_hooks:15:in `<main>'
(See full trace by running task with --trace)

当我运行完整跟踪

 rake generate_secret_token --trace

这就是我得到的；

Answer 1

检查您的 rake 任务是否具有以下格式：

namespace :your_namespace do
  desc 'Description for rake task'
  task generate_secret_token: :environment do
  end
end

虽然运行正在执行 rake 任务，运行作为 'rake namespace:generate_secret_token'

Answer 2

rake db:migrate

此命令用于运行您的数据库迁移。

rake task_name

这个命令用于运行你写的rake任务lib/tasks文件夹
