db_migrate not migrating

[danhixon]

I've added a migration but it doesn't run when I deploy. I try:

$ mina rails:db_migrate
-----> DB migrations unchanged; skipping DB migration

I tried:

force_migrate=true mina rails:db_migrate
-----> Migrating database
Could not locate Gemfile

I tried:

$ diff -r 264/db/migrate 265/db/migrate
Only in 265/db/migrate: 20150320184220_add_redirect_to_communication_types.rb

I'd love any ideas on what I can do to make this work? Thanks in advance! Mina is so good.

Your schema.db did not change between two deploys. That is how mina determines if it nees to run migrate or not.

rails:db_migrate is a task meant to be run inside deploy do as invoke :'rails:db_migrate'

you need to do this:

mina 'rake[db:migrate]' 

or change your schema.db

Thanks for the quick reply! That definitely worked and make my migration run. Any chance you help me so they'll run automatically? I thought that the migrations ran when the contents of db/migrate changed between deploys. See: https://github.com/mina-deploy/mina/blob/master/lib/mina/rails.rb#L143-L145

You need to add that inside your deploy script
there rails taksk are meant to be invoked inside deploy scripts as stated here: https://github.com/mina-deploy/mina/blob/master/lib/mina/rails.rb#L128

add something like this to your deploy.rb script:

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    to :launch do
      queue "mkdir -p #{deploy_to}/#{current_path}/tmp/"
      queue "touch #{deploy_to}/#{current_path}/tmp/restart.txt"
    end
  end
end

I have that. It is working for me in another project I have but not this one. I'll figure it out eventually.

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    to :launch do
      invoke :restart_services
    end
  end
end
