Capistrano deploy:migrate and db:migrate run all migrations every time

capistrano, rake, ruby, ruby-on-rails, ruby-on-rails-3

Solution

OK, figured it out... though how anybody else in the stackosphere was supposed to do the same based on the red herrings in my original question is beyond me.

The problem was that my production database was set to

db/production.sqlite3

Because it was a sqlite database in the main project directory, it was getting axed every time I ran

cap deploy

Then, when I would run

cap deploy:migrate

It would find an empty database and think all migrations needed to be run. I solved this by changing the database path to

/my_absolute_path/shared/db/production.sqlite3

Thanks to @TheMahvin and anyone else who attempted to take on the hopeless task of answering my poorly worded question!

H/T to this question, which made the scales fall from my eyes:

Capistrano Deploy Wipes Database?

Problem

So, I'm diddling around with rails (ruby 1.9.3p392, rails 3.2, sqlite3 db) and I'm trying to deploy the ubiquitous blog tutorial code to a "production" server (apache, passenger, ubuntu). My deploy.rb looks like this: ``` require 'bundler/capistrano' require 'rvm/capistrano' load 'deploy/assets' set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"") set :rvm_type, :user set :user, 'blah' set :application, 'railsTest' set :domain, 'www.blah.com' set :applicationdir, "/home/sean/public/blah.com/public" set :scm, 'git' set :repository, "ssh://blah@1.1.1.1/home/blah/public/bla.com/public/capDep.git" #set :git_enable_submodules, 1 # if you have vendored rails set :branch, 'master' set :git_shallow_clone, 1 set :scm_verbose, true set :use_sudo, false # roles (servers) role :web, domain role :app, domain role :db, domain, :primary => true # deploy config set :deploy_to, applicationdir set :deploy_via, :export set :migrate_target, :latest # additional settings default_run_options[:pty] = true # Forgo errors when deploying from windows #ssh_options[:keys] = %w(/home/blah/.ssh/id_rsa) ssh_options[:forward_agent] = true # if you want to clean up old releases on each deploy uncomment this: # If you are using Passenger mod_rails uncomment this: namespace :deploy do 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 #after "deploy:update_code", "deploy:migrate" ``` Now, I am sure that must look like a big hot mess to those who know what they are doing with capistrano, but I am an utter rube. In the end, despite my inadequacies, the deploy seems to work, because when I run the following ``` cap deploy:setup cap deploy ``` my app is up and running and, just because I can, I add a few rows to a table in the db via the web ui that was created for me by rails. Now, I get bold and create a migration, adding a column to a table. I push my changes to git. To my horror, when I run ``` cap deploy ``` ALL the migrations are run, which recreates the tables, thus destroying all my data. I have repeated this painful process several times. My schema_migrations table looks like this: ``` 20130620210004 20130620220229 20130628213331 20130628214946 20130628223002 ``` What am I missing here? UPDATE: I recently gave @TheMahrvin's suggestion regarding running deploy:migrations at the command line and removing it from the deploy.rb. It didn't work... once again, all migrations were run. My muse must have whispered something in my ear, because I decided to try running db:migrate on the server itself. I was astonished to see this output after running just "rake": ``` 20130717230110 CreateHighScores 20130717230342 CreateGames 20130717231041 AddGameTypeToGame 20130717233707 AddGamePublisherToGame 20130717234124 AddGameRatingToGame 20130731210558 AddGameMechanicToGame ``` Only the last migrations should be pending. So, perhaps this isn't a problem with Capistrano at all (I've updated the title of this question to reflect that). So, why are the previous migrations still being flagged as pending? I know they were run in the past, both because I saw them in the output and verified the db schema after they ran. UPDATE #2: Setup another migration and ssh'd into the server and cd'd my way to the "current" directory, which if I understand capistrano at all (fat chance) is where the current files are. Running ``` bundle exec rake db:migrate:status ``` got me: ``` Status Migration ID Migration Name -------------------------------------------------- down 20130717230110 Create high scores down 20130717230342 Create games down 20130717231041 Add game type to game down 20130717233707 Add game publisher to game down 20130717234124 Add game rating to game down 20130731210558 Add game mechanic to game down 20130731212454 Add publish year to game down 20130731214515 Add game rank to game down 20130731214928 Add game abbr to game down 20130731215749 Add crazy field to game ``` I can't help feeling that there is something profoundly wrong with what I am trying to do.
