I will now explain what capistrano does and why you need to undertand how your app was deployed. Capistrano read the deploy.rb file and finds out the name of the web server, the repository server and the db server. all this info must be put in the deploy.rb file by the developer. Then you specify your versioning system, in your irb file there must be something like this set :deploy_via, :remote_cache set :scm, 'git' set :branch, 'master' set :scm_verbose, true set :use_sudo, false what capistrano does the first time you deploy your app is, it creates a folder structure where it puts a release directory, in it is at least the last 5 versions of the app, next to it is a current directory, this current directory is a symbolink link to the latest realease in the releases directory. You , the developer make Passenger point to the public directory of the current directory, that is , in your httpd file there should be a host to app_path/current/public. It also creates a shared folder where data that is common between releases i stored. That is what happens the first time you are going to deploy with the command cap deploy:setup after that for each deployment it does this : 1 Checkouts the head of the master branch from the specified repository server via the specified version management system 2 Rebuild the symbolic link of the current directory so that it now point to the latest release in the releases directory. 3 Touches the file current/tmp/restart.txt , which causes passenger to restart As you can see is posible that you are editing 1) the app that is sometime directly in the deploy_to path and not the one inside the current directory 2) One of the releases that is not the current 3) the wrong restart.txt The best way to update your app is via capistrano, this are the steps if you dont have access to the source code, if you do you can go to 3 1) Find out where is the repository 2) do git clone path_to_repository 3) check for the database.yml file since it is posible that it was not version managent and is missing 4) if is not there make one and add the proper servers 5) bundle install <====== to install the gems 6) git checkout -b updating_static <========to create a branch and not mess up the original code 7) edit at will 8) git checkout master 9) git merge updating_static <======== to apply your changes to the master 10 ) git push origin master <==== this should send the changes to the repository Here is where you start to use capistrano 11) cap deploy <=== it may ask for password serveral times , each time it connect to one of the servers you are done. As you can see with capistrano everything takes one command, cap deploy, everything above was so you can have a copy of the app in your development machine. Capistranos has everything it need in the deploy.rb file is in the repository pull it and checkit out, if you want to you can put it here ( remove any passwords and ip) and we can tell you what is suppose to do. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
