ruby on rails - Run a command in the context of a different app -


i have 2 rails apps on same server, let's call them , b.

i trying have app restart app b via app b's own capistrano task. unfortunately, after cd-ing app b's directory, trying run app a's capistrano instead. missing something?

example code

system("cd /apps/appb/current && pwd && bundle exec cap:restart")

pwd correctly returns path of appb (/apps/appb/current), however, in there traceback cap:restart. because still trying run cap command in context of appa, e.g.

/apps/appa/shared/bundle/ruby/1.9.1/gems/capistrano-2.15.4/lib/capistrano/configuration/loading.rb:152:in 'require': cannot load such file -- airbrake/capistrano (loaderror) /apps/appa/shared/bundle/ruby/1.9.1/gems/capistrano-2.15.4/lib/capistrano/configuration/loading.rb:152:in 'require'.

i tried without 'bundle exec', , have tried other ways of making system calls. created bash script in directory , tried run way.

all methods described exhibit same behaviour.

your appreciated =)

you need use bundler.with_clean_env ensure subprocess doesn't pick current bundler environment:

bundler.with_clean_env   system("cd /apps/appb/current && pwd && bundle exec cap:restart") end

this same problem install bundle of gem within other rails application

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
