我想创建一个基本的任务来复制和链接database.yml文件到我的应用程序，但我不明白为什么它不工作。如何在另一个Capistrano的任务中调用Capistrano的任务？
我使用Capistrnao 3.1
这是我的lib/Capistrano酒店/任务/ 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
这是我得到的输出中：
[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
我不知道如何调用其他任务。我inspirate myslef从https://github.com/capistrano/capistrano/blob/master/lib/capistrano/tasks/deploy.rake
如果我尝试没有 '调用' 关键字，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
结果如下：
[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
** Invoke db_access:create_symlinks (first_time)

这必须是一个简单的syntaxe错误，但因为我找不到解释我不知道该怎么做的指南。
感谢您的帮助
