How to run custom rake task via capistrano 3?
capistrano, capistrano3, rake, ruby, ruby-on-rails
Solution
Based on the `capistrano/rails` gem: https://github.com/capistrano/rails/blob/master/lib/capistrano/tasks/migrations.rake
namespace :somenamespace do
task :runrake do
on roles(:all) do
within release_path do
with rails_env: fetch(:rails_env) do
execute :rake, ask :task
end
end
end
end
end
Problem
which way, i can run rake commands via capistrano on remote server. for example i have a `lib/task/reparse.rake` with some methods ``` desc "it's take csv file, makes some changes and fill db with this info" task :example1 => :environment do require 'csv' rows_to_insert = [] # some actions # ... end ``` on local server all is fine - i just run `rake reparse:example1` and it's work(fill db correctly). so question is - how can i run this command on real hosting, after deploy? i'am using rails 4.1 + capistrano 3. P.S. examples from site not work for me How do I run a rake task from Capistrano? if i try `cap production rake:invoke task=reparse:land` it fails with: ``` cap aborted! Don't know how to build task 'rake:invoke' ``` some fixes ``` namespace :somenamespace do task :runrake do on roles(:all), in: :sequence, wait: 5 do within release_path do execute :rake, ENV['task'], "RAILS_ENV=production" end end end end ``` with such way it begin to execute via ``` cap production somenamespace:runrake task=custom_task_file:custom_method1 ```
