No such file or directory during cap deploy:update - ruby-on-rails

I noticed in the output from cap deploy:update, that it is triggering "deploy:assets:precompile" as an after callback for deploy:update_code:
triggering after callbacks for `deploy:update_code'
* 2013-05-15 11:32:16 executing `deploy:assets:precompile'
triggering before callbacks for `deploy:assets:precompile'
* 2013-05-15 11:32:16 executing `deploy:assets:update_asset_mtimes'
* executing "[ -e /home/johnmerlino/public_html/store.johnmerlino.com/shared/assets/manifest* ] && cat /home/johnmerlino/public_html/store.johnmerlino.com/shared/assets/manifest* || echo"
servers: ["xxx.xx.xx.xxx"]
[xxx.xx.xx.xxx] executing command
command finished in 314ms
* executing "cd -- /home/johnmerlino/public_html/store.johnmerlino.com/releases/20130515153214 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile"
servers: ["xxx.xx.xx.xxx"]
[xxx.xx.xx.xxx] executing command
** [out :: xxx.xx.xx.xxx] rake aborted!
** [out :: xxx.xx.xx.xxx] No such file or directory - /home/johnmerlino/public_html/store.johnmerlino.com/releases/20130515153214/config/config.yml
** [out :: xxx.xx.xx.xxx
Now the problem there is it says that the latest release doesn't have a "config.yml" file.
Actually in my capistrano script, that file is created after "deploy:update_code":
after "deploy:update_code", "deploy:symlink_shared_configs"
namespace :deploy do
desc "Symlink configuration files"
task :symlink_shared_configs, :roles => [:db,:app] do
run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
run "ln -nfs #{shared_path}/config/config.yml #{release_path}/config/config.yml"
end
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
So shouldn't config.yml be created by this time?

If both are being triggered in the list of callbacks for after deploy:update_code then they're essentially part of the same callback group, but the order in which callbacks in the same group are called depends on the implementation of the callback registration and execution.
If you need them to run in a given order then you can explicitly change when assets:precompile is run by moving it later, or moving the config.yml file earlier in order to guarantee that one comes before the other.
As it stands now, since they both run in the after deploy:update_code the order in which they get executed could be either:
...before...
deploy:update_code
...after... | after group
deploy:symlink_shared_configs | after group
deploy:assets:precompile | after group
...OR...
...before...
deploy:update_code
...after... | after group
deploy:assets:precompile | after group
deploy:symlink_shared_configs | after group
...and based on the fact that you've posted this question, it sounds like the latter instance is happening for you.

Why I'm getting "undefined local variable or method `rails_env'"?

I'm getting undefined local variable or method 'rails_env'when doing
execute "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:stop"
I'm not a big capistrano or rails expert.
On deploy.rb I have
namespace :solr do
desc "start solr"
task :start do
on roles(:app) do
execute "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:start"
end
end
desc "stop solr"
task :stop do
on roles(:app) do
execute "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:stop"
end
end
desc "reindex the whole database"
task :reindex do
on roles(:app) do
invoke 'solr:stop'
execute "rm -rf #{shared_path}/solr/data/*"
invoke 'solr:start'
execute "cd #{current_path} && RAILS_ENV=#{rails_env} d"
end
end
desc "Symlink in-progress deployment to a shared Solr index"
task :symlink do
on roles(:app) do
execute "ln -s #{shared_path}/solr/data/ #{release_path}/solr/data"
execute "ln -s #{shared_path}/solr/pids/ #{release_path}/solr/pids"
invoke 'solr:reindex'
end
end
end
after "deploy:finishing", "solr:symlink"
And on deploy/staging.rb I have
set :rails_env, :staging
What's missed?
You should use fetch method. So, instead of rails_env use:
fetch(:rails_env)
Here (or here) is more details.
Try replacing rails_env with Rails.env

capistrano3: Don't know how to build task 'deploy:create_db'

I use capistrano3 to deploy my rails app.
deploy.rb
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
When I run cap -T, the error occurred as below:
(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

Hope someone can help me, Thanks in advance!!!
I think you should define tasks first...
Try this:
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

capistrano on_rollback not being called

I'm using capistrano v2 for a Rails 3.2 I have a bundler task in my deploy.rb like so;
# Bundler tasks
namespace :bundler do
desc "Create a symlink"
task :create_symlink, :roles => :app do
shared_dir = File.join(shared_path, 'bundle')
release_dir = File.join(release_path, '.bundle')
run("mkdir -p #{shared_dir} && ln -s #{shared_dir} #{release_dir}")
end
desc "Install required gems"
task :install, :roles => :app do
puts "New Release"
run "cd #{release_path} && #{bundle_path} install"
on_rollback do
if previous_release
puts "Rollback"
run "cd #{previous_release} && #{bundle_path} install"
else
logger.important "no previous release to rollback to, rollback of bundler:install skipped"
end
end
end
desc "Run bundler on new release"
task :bundle_new_release, :roles => :db do
bundler.create_symlink
bundler.install
end
end
after "deploy:update_code", "bundler:bundle_new_release"
after "deploy:rollback:revision", "bundler:install"
When I run cap deploy:rollback it doesn't run the the on_rollback code it tries to run the cd {release_path}.
I got this example from http://kazjote.eu/2010/08/04/bundler-and-capistrano-the-right-way.
Since you didn't give any logs, I can't say for sure if deploy:rollback is deploying the previous version as it should, however you're confusing deploy:rollback (a task), with on_rollback (a hook).
on_rollback would be called only if the task :install failed. However, I also believe you need to define a transaction for the on_rollback hook to actually fire (and possibly have to make the on_rollback definition before your 'run "cd...')
deploy:rollback should run your deploy tasks with the previous successful release.
I found a simpler example here:
http://pedz-bits.blogspot.com/2012/09/capistrano-errors-ensure-and-onrollback.html
namespace :fun do
desc "Sample showing rescue, ensure, and on_rollback inside a transaction"
task :stuff, :roles => :app do
transaction do
on_rollback { logger.debug "my rollback" }
begin
logger.debug "main"
# Either run or run_locally will work the same
# run_locally "false"
run "false"
rescue => e
logger.debug "rescue #{e.class}"
raise e
ensure
logger.debug "ensure"
end
end
end
end
Command output:
cap fun:stuff
* executingD `fun:stuff'
** transaction: start
* main
* executingB "false"
servers: ["condor.austin.ibm.com"]
[condor.austin.ibm.com] executingA command
command finished in 771ms
* rescue Capistrano::CommandError
* ensure
*** [fun:stuff] rolling back
* my rollback
failed: "bash -l -c 'false'" on condor.austin.ibm.com
Notes
on_rollback executes only if the error happens while a transaction is active.
on_rollback must also be defined within the transaction.
raise e to make sure task exits with an error or higher level process will assume it completed successfully.
ensure works as you expect.

Capistrano deployment behaviour

I have this deploy.rb
after 'deploy:update_code', 'deploy:symlink_db', 'deploy:symlink_email'
after 'deploy:setup', 'setup:create_db_configuration', 'setup:create_email_configuration'
namespace :deploy do
desc "Symlinks the email.yml"
task :symlink_email, :roles => :app do
puts "##Sybolic Link the email.yml"
run "ln -nfs #{deploy_to}/shared/config/email.yml #{release_path}/config/email.yml"
end
desc "Symlinks the database.yml"
task :symlink_db, :roles => :app do
puts "##Sybolic Link the database.yml"
run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
end
But when I deploy, after the deploy:update_code it starts with
2013-07-27 03:30:30 executing `deploy:assets:symlink'
then
2013-07-27 03:30:32 executing `deploy:assets:precompile'
And when execution
executing "cd -- /home/ubuntu/deployments/saleshub/releases/20130727013023 && RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile"
It fails, because the symbolic links were not created yet. How do I make sure the my tasks to create the symlinks before compiling the assets?
before 'deploy:assets:precompile', 'deploy:symlink_db', 'deploy:symlink_email'

Capistrano Trouble From Git

I am new to using git and Capistrano. I have setup everything else on my server and pushed my app onto a git repo (http://github.com/tnederlof/daily-trailer). When I go to run cap deploy:cold everything seems to be working until it tries to rake the db. Below is what I get when I run it, this is the last bunch of information I recieve and where the error occurs:
* executing "cd /var/www/dailytrailer.net/releases/20100205052047; rake RAILS_ENV=production db:migrate"

Can someone please help me figure out what script/spin is all about?
Thank you!
Do you know what you're trying to use for an app server? If it's Passenger, then you've got something screwed up in your deploy.rb. (Post that file if you want more help debugging this.) If it's mongrel, then this should be helpful.
