如何通过rails中的命令行运行rake任务

Question

I have defined a rake task as follows in a file called file_locker_task.rake

namespace :myspace do
   task :process => :environment do
      FileLocker.lock_files   
   end
end

How do I execute this rake task from the command line? I tried:

rake myspace:process and rake process but both are throwing an error like this:

rake aborted!
Don't know how to build task 'process'

Answer 1

1. Run rake -T -A from your Rails home directory to see all the tasks that rake knows about. Yours must be in that list for rake to run it.
2. By default, in a Rails app, rake looks in the lib/tasks directory and its subdirectories for your .rake files. Check that. (I suspect this is the problem.)

Answer 2

According to docs

Any ruby file (including other rakefiles) can be included with a standard Ruby require command.

-

Additional rake files (with the file extension “.rake”) may be placed in rakelib directory located at the top level of a project (ie the same directory that contains the main Rakefile). Also, rails projects may include additional rake files in the lib/tasks directory.
