capistrano3 : 'deploy : create_db'작업을 빌드하는 방법을 모름

Question

capistrano3를 사용하여 레일 앱을 배포합니다.

namespace :deploy do 
    after "deploy", "deploy:create_db" 
    after "deploy", "deploy:migrate" 
    after "finishing", "deploy:restart" 

    task :restart do 
    on roles(:web) do 
     execute "mkdir -p #{current_path}/tmp" 
     execute "touch #{current_path}/tmp/restart.txt" 
    end 
    end 

    task :create_db do 
    on roles(:web) do 
     execute "cd #{current_path}; bundle exec rake db:create RAILS_ENV=#{rails_env}" 
    end 
    end 

end 

내가 cap -T 실행

가, 오류가 아래와 같이 발생 deploy.rb : 사전에

(Backtrace restricted to imported tasks) 
cap aborted! 
Don't know how to build task 'deploy:create_db' 

(See full trace by running task with --trace) 

cap -T --trace

** Invoke load:defaults (first_time) 
** Execute load:defaults 
cap aborted!

나는

이 시도 ... 처음 작업을 정의해야한다고 생각 :

namespace :deploy do 

    task :restart do 
    on roles(:web) do 
     execute "mkdir -p #{current_path}/tmp" 
     execute "touch #{current_path}/tmp/restart.txt" 
    end 
    end 

    task :create_db do 
    on roles(:web) do 
     execute "cd #{current_path}; bundle exec rake db:create RAILS_ENV=#{rails_env}" 
    end 
    end 

    after "deploy", "deploy:create_db" 
    after "deploy", "deploy:migrate" 
    after "finishing", "deploy:restart" 
end
