I'm struggling to get a decent understanding of capistrano. I want to run rails commands in production but it seems that the corresponding binstub is nowhere to be found. As a matter of fact, I have the current/ and shared/ directories under my app name, but none of both has a bin/ directory with a rails binstub.
I'm also a complete newbie at building capistrano tasks. I found out this gem for example to run rails c with capistrano, but it requires the rails binstub in the current/bin directory, which of course I don't have.
For your reference, here's my config/deploy.rb:
set :scm, :git
set :repo_url, '<git_repo>'

set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log, "#{release_path}/log/puma.access.log"
set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) }
set :puma_preload_app, true
set :puma_worker_timeout, nil
set :puma_init_active_record, true # Change to false when not using ActiveRecord

Am I missing something? Thanks in advance
