Question

我有一个要在运行rails tmp:clear后运行的任务

namespace :myapp do
  task :clear do
    # do some stuff
  end
end

我了解到可以通过增强该任务来做到这一点：

Rake::Task['tmp:clear'].enhance(['myapp:clear'])

问题是当我的代码加载时，tmp:clear是未定义的，因此失败：

$ rails tmp:clear
rails aborted!
 Don't know how to build task 'tmp:clear' (See the list of available tasks with `rails --tasks`)
 myapp/lib/tasks/clear.rake:7:in `<top (required)>'

Answer 1

在本地任务之后加载任务。您需要require 'rails/tasks'才能规避该问题。

完整的解决方案：

require 'rails/tasks'

namespace :myapp do
  task :clear do
    puts "do some stuff"
  end
end

Rake::Task['tmp:clear'].enhance(['myapp:clear'])

在“ tmp：clear”之后运行任务
