Capistrano 3在钩子之前和之后

Question

I just switched to using Capistrano 3 and ran into some issues with the before and after hooks documentation.

In the docs it show the following for calling existing tasks

before :starting, :ensure_user
after :finishing, :notify

If I use this syntax I get 'Don't know how to build task starting' Instead I had to do the following to get my tasks to work.

before "deploy:starting", "dj:stop"
after "deploy:finished", "dj:start"

The dj tasks are in Capistrano tasks directory in a *.rake file. Any ideas on what I may be missing or do the docs need to be updated?

Answer 1

You can only use the shortcut version ( before :starting, :ensure_user ) when both tasks are inside the same namespace. When you want to execute tasks from different namespaces, you need to include the namespace inside the string ( before "deploy:starting", "dj:stop" ).
