Adding Images to your application

We are going to use the new and shiny ActiveStorage that is built into Rails 5! https://edgeguides.rubyonrails.org/active_storage_overview.html

We will add receipt images to transactions in our mint application. This way we can snap a photo of our receipt and attach it to our transaction.

Helpers

View helpers are useful files that contain reusable code in an attempt to keep your views DRY and clean. They can be found in the /app/helpers directory. You can simply add methods here that you intend to reuse in your views.

Let's say you want to method to format a date object a specific way all the time (January 1, 2019). You could create a method here called mint_date(date) and place your logic inside. This method then can be used anywhere in any view.

In /app/helpers/application_helper.rb:

Assignment 9

We are going to use Heroku to deploy our applications, to do this we are going to use git-style commands to automate our deployments.

Your assignment this week is to try and get your Mint application and your Final Project running on Heroku

First we need to create all the appropriate accounts and install all the necessary development tools

Prepping our Computers and Accounts

Install Homebrew (package manager)

https://docs.brew.sh/Installation

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install RBENV using Homebrew (ruby manager)

Setting up for Heroku deployments

Create a heroku account https://signup.heroku.com/
download heroku command line tools https://devcenter.heroku.com/articles/heroku-cli, I recommend that you install this on your computer and NOT in docker. (for OSX users you'll probably want to install Homebrew https://brew.sh/ and do the install using the brew commands so that you can do brew tap heroku/brew && brew install heroku)
Log into heroku using your heroku-cli heroku login
