Use Heroku config to get ENV variables. (https://github.com/ddollar/heroku-config)

1

heroku config:pull --remote staging

Delete extra lines in .env, leaving only those needed for app to function properly. For example: BRAINTREE_MERCHANT_ID and S3_SECRET.

Use Foreman to run the app locally (https://github.com/ddollar/foreman)

foreman start

It uses your .env file and Procfile to run processes like Heroku’s Cedar stack. (https://devcenter.heroku.com/articles/cedar)

Code Review

https://github.com/thoughtbot/guides/tree/master/code-review

  • Review data integrity closely, such as migrations that make irreversible changes to the data, and whether there is a related todo to make a database backup during the staging and production deploys.

  • Review SQL queries for potential SQL injection.

  • Review whether dependency upgrades include a reason in the commit message, such as a link to the dependency’s ChangeLog or NEWS file.

  • Review whether new database indexes are necessary if new columns or SQL queries were added.

  • Review whether new scheduler (cron) tasks have been added and whether there is a related todo in the project management system to add it during the staging and production deploys.
