How to create a Ruby gem that adds Rake tasks

Create a gem

One way to do this is to use bundler to scaffold our gem:

bundler gem my_gem

Add rake tasks to our gem

I prefer to put tasks meant to manage the gem itself in lib/tasks, and tasks the gem is meant to provide to gem users in lib/my_gem/tasks.

# The following comments fill some of the gaps in Solargraph's understanding of
# Rails apps. Since they're all in YARD, they get mapped in Solargraph but
# ignored at runtime.
#
# You can put this file anywhere in the project, as long as it gets included in
# the workspace maps. It's recommended that you keep it in a standalone file
# instead of pasting it into an existing one.
#
# @!parse
#   class ActionController::Base

Get the heroku database name:

heroku pg:info

Name can be found in the reponse from the command above. For example: Add-on: soaring-newly-1337.

namespace :db do
  desc "Backs up heroku database and restores it locally."
  task import_from_heroku: [ :environment, :create ] do
    HEROKU_APP_NAME = nil # Change this if app name is not picked up by `heroku` git remote.

    c = Rails.configuration.database_configuration[Rails.env]
    heroku_app_flag = HEROKU_APP_NAME ? " --app #{HEROKU_APP_NAME}" : nil
    Bundler.with_clean_env do
      puts "[1/4] Capturing backup on Heroku"
      `heroku pg:backups capture DATABASE_URL#{heroku_app_flag}`
