cap deploy not running migrations

Question

I'm using Capistrano 3.2.1 with Ruby 2.1.1 and Rails 4.1.4 and for some reason I'm unable to run migrations.

I tried running cap staging deploy (deploys but doesn't run migrations), cap staging deploy:migrate (does nothing), cap staging deploy:migrations (don't know how to build task).

Gemfile:

group :development, :test do
    gem 'capistrano', '~> 3.2.1'
    gem 'capistrano-rails', '~> 1.1.1'
    gem 'capistrano-rvm'
end

Capfile:

set :deploy_config_path, 'config/capistrano/deploy.rb'
set :stage_config_path, 'config/capistrano/deploy'

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rails'
require 'capistrano/rvm'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

Answer 1

您需要在Capfile中添加require'capistrano require 'capistrano/rails/migrations'

Answer 2

A short trip to capistrano-rails github solved the problem. I was missing db role on my webservers...

Answer 3

Running "cap deploy:migrations" is equivalent to running "cap deploy" && subsequently "cap deploy:migrate" in one command.

To view the description for deploy:migrations, just use the -e option:

cap -e deploy:migrations

will give you this output:

cap deploy:migrations

Deploy and run pending migrations. This will work similarly to the 'deploy' task, but will also run any pending migrations (via the 'deploy:migrate' task) prior to updating the symlink. Note that the update in this case it is not atomic, and transactions are not used, because migrations are not guaranteed to be reversible.
