Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

emacs --daemon to run in the background. emacsclient.emacs24 <filename/dirname> to open in terminal

NOTE: "M-m and SPC can be used interchangeably".

Undo - C-/
Redo - C-?
Change case: 1. Camel Case : M-c 2. Upper Case : M-u

Lower Case : M-l

1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.

Change your database RDS instance security group to allow your machine to access it.
- Add your ip to the security group to acces the instance via Postgres.
Make a copy of the database using pg_dump
- $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
- you will be asked for postgressql password.
- a dump file(.sql) will be created
Restore that dump file to your local database.
- but you might need to drop the database and create it first
- $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>

the database is restored

Working with images

We now have everything we need to build a web app, except for images and other binary files. Your application will likely not get a lot of engagement if its not visual. In this lesson, we shall be adding the ability to upload images to your Posts api.

Since this will be a continuation from the class on Deploying to production you are adviced to start by cloning that workspace and then working from there.
