The Complete Guide to Nested Forms in Phoenix

I recently spent some time dealing with nested forms in Phoenix. Nested forms are great when you want to create multiple database records in a single transaction and associate them with each other. I am new to Phoenix and really struggled to find any resources that helped me with my specific problem. I decided to document what I learned in the process in hopes of helping others that are new to Elixir and Phoenix.

Here is my attempt at a one stop shop to learn everything you will need to know about nested forms. If you would like to view the GitHub repo you can check it out here.

Thanks to Heartbeat and Jose for excellent blog posts on nested forms. Also shoutout to Josh for showing me some examples at Ruby

Общие упрощенные понятия. Возможно существуют способы задать другое поведение нежели данное упощенное.

Понятия

• producer - отправитель, программный код, который отправляет сообщение.
• consumer - получатель, программный код, который должен получить сообшение.
• exchange - обменник, функционал RabbitMQ, получает сообщение с заданными параметрами от отправителя и:
  • может сбросить(удалить) сообщение или вернуть отправителю (зависит от атрибутов сообщения),
  • может отправить сообщение в очередь,
  • может отправить сообщение в несколько очередей (сообщение будет скопировано для каждой очереди)
• queue - очередь, функционал RabbitMQ, хранит все сообщения и раздает их получателям.
• message - сообщение, содержит атрибуты необходимые RabbitMQ, а также данные для передачи от отправителя к получателю

A Guide to Encrypting Files with Mac OS X

This guide will demonstrate the steps required to encrypt and decrypt files using OpenSSL on Mac OS X. The working assumption is that by demonstrating how to encrypt a file with your own public key, you'll also be able to encrypt a file you plan to send to somebody else using their private key, though you may wish to use this approach to keep archived data safe from prying eyes.

Too Long, Didn't Read

Assuming you've already done the setup described later in this document, that id_rsa.pub.pcks8 is the public key you want to use, that id_rsa is the private key the recipient will use, and secret.txt is the data you want to transmit…

Encrypting

$ openssl rand 192 -out key

$ openssl aes-256-cbc -in secret.txt -out secret.txt.enc -pass file:key
