Updating a feature branch

First we'll update your local master branch. Go to your local project and check out the branch you want to merge into (your local master branch)

$ git checkout master

Fetch the remote, bringing the branches and their commits from the remote repository. You can use the -p, --prune option to delete any remote-tracking references that no longer exist in the remote. Commits to master will be stored in a local branch, remotes/origin/master

From: Linus Torvalds <torvalds@linux-foundation.org>, Junio C Hamano <gitster@pobox.com>
Subject: Re: Odd merge behaviour involving reverts
Abstract: Sometimes a branch that was already merged to the mainline
 is later found to be faulty.  Linus and Junio give guidance on
 recovering from such a premature merge and continuing development
 after the offending branch is fixed.

Best practices написание REST-API

• Имена полей в ответе задавать в snake_case (prr_page, created_at, system_name,...)
• Для времени использовать ISO 8601 (формат: YYYY-MM-DDTHH:MM:SSZ)
• Отдавать данные (сам контент, поля сущностей, массивы сущностей), помещая их в data

Использование REST методов и примеры url'ов

• GET: /api/users — получить список пользователей;
• GET: /api/users/123 — получить указанного пользователя;
• POST: /api/users — создать нового пользователя;

Workaround for pushing to heroku database on windows machince.

Context:

The command heroku pg:push essentially executes two commands under the hood. First, it executes pg_dump, which makes a backup file of a specific database. Then, it pipes that file into pg_restore, where it takes that dump file and uses it to restore another database. The way we usually use it is to push a local database to a deployed heroku database.

The problem is that on windows, the command breaks while trying to pipe in the backup file from pg_dump to pg_restore, so we need to do these two commands manually.

Solution:
