推荐答案

像这样创建一个特定于应用程序的任务(如 Alex Kaushovik 建议的那样)...

Create an application specific task (as Alex Kaushovik suggested) like so...

创建一个文件 lib\tasks\db_schema_override(实际名称无关紧要，你需要在 lib\tasks 中有一个 .rake 文件)，内容如下(归功于 Matthew Bass remove_task)

Create a file lib\tasks\db_schema_override (actual name doesn't matter, you need a .rake file in lib\tasks) with contents as below (credit to Matthew Bass for remove_task)

Rake::TaskManager.class_eval do
  def remove_task(task_name)
    @tasks.delete(task_name.to_s)
  end
end

Rake.application.remove_task('db:schema:dump')
namespace :db do
  namespace :schema do
    task :dump do
      # Overridden to do nothing
    end
  end
end
