我想創建一個基本的任務來複制和鏈接database.yml文件到我的應用程序，但我不明白爲什麼它不工作。如何在另一個Capistrano的任務中調用Capistrano的任務？
我使用Capistrnao 3.1
這是我的lib/Capistrano酒店/任務/ databases.cap文件：
namespace :db_access do
# Idea : https://github.com/capistrano/sshkit/blob/master/EXAMPLES.md
desc 'Copy production database.yml from local workstation'
task :copy_production do
on roles :all do
execute :mkdir, '-p', "#{shared_path}/config"
upload! 'config/deploy/production.database.yml', "#{shared_path}/config/database.yml"
end
end
# Idea : http://stackoverflow.com/questions/9684649/capistrano-cant-deploy-my-database-yml
desc 'Create database.yml symlinks to current release'
task :create_symlinks do
on roles :all do
unless test "[ -f #{shared_path}/config/database.yml ]"
invoke 'db_access:copy_production'
end
execute :ln, "-nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
end
end
這是我得到的輸出中：
[email protected]:/var/www/odpf$ cap production db_access:create_symlinks
DEBUG [3f670dfd] Running /usr/bin/env [ -f /var/www/odpf/shared/config/database.yml ] on myserver.net

cap aborted!

Tasks: TOP => db_access:create_symlinks
我不知道如何調用其他任務。我inspirate myslef從https://github.com/capistrano/capistrano/blob/master/lib/capistrano/tasks/deploy.rake
如果我嘗試沒有 '調用' 關鍵字，不 '' 的招牌：
namespace :db_access do
# Idea : https://github.com/capistrano/sshkit/blob/master/EXAMPLES.md
desc 'Copy production database.yml from local workstation'
task :copy_production do
on roles :all do
execute :mkdir, '-p', "#{shared_path}/config"
upload! 'config/deploy/production.database.yml', "#{shared_path}/config/database.yml"
end
end
# Idea : http://stackoverflow.com/questions/9684649/capistrano-cant-deploy-my-database-yml
desc 'Create database.yml symlinks to current release'
task :create_symlinks do
on roles :all do
unless test "[ -f #{shared_path}/config/database.yml ]"
db_access.copy_production
end
execute :ln, "-nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
end
end
結果如下：
[email protected]:/var/www/odpf$ cap production db_access:create_symlinks --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults

這必須是一個簡單的syntaxe錯誤，但因爲我找不到解釋我不知道該怎麼做的指南。
感謝您的幫助
