Challenge time: one weekend

The challenge was to build Instagram using Rails. An app should have users who can post pictures, write comments on pictures and like a picture.

Online on https://enjoy-instagram.herokuapp.com/

• Download the source code using $ git clone

• Navigate into the root of the directory using $ cd instagram-challenge

• Install all the dependencies by running the command $ bundle install in the root directory

• Download PostgreSQL (if you do not already have it installed)

• brew install imagemagick for uploading pictures

• brew install phantomjs for testing js ajax calls

• Within the command line, run $ bin/rake db:create and then $ bin/rake db:migrate

• Run the app using the command $ bin/rails server

• Go to localhost:3000 in the route of a browser to view and interact with the app

Within the root of the directory, run $ rspec to see the results of the tests in the command line

• Application written in Ruby 2.3.3 and built using Ruby on Rails
• Based on a PostgreSQL database with ActiveRecord as the ORM
• Tested using RSpec and Capybara
• Uses Paperclip gem for uploading pictures
• Uses Devise for User Sign up and Log in
• Use AWS to store the pictures on S3 Bucket

  As a user
  So that I post pictures
  I need to register and log in to the website

  As a user
  So that I can post pictures
  I want to be able to upload a picture

  As a user
  So that I can interact with other users
  I want to be able to leave comments on their pictures

  As a user
  So that I can interact with other users
  I want to be able to leave 'likes' on their pictures

• In the very beginning I decided to have a picture model to represent each post, with a description and an image as its properties. Each picture has comments and likes, which in turn are represented by their own models. Each picture also belongs to a user, created with the help of devise gem.

• I have built a schema based on this domain model

If I had a chance to start the project from the beginning, I would work more on the following:

• would use factory_girl gem as a factory of objects for my tests. Unfortunately I've learnt about this gem quite late to change my tests. Otherwise, the tests would look more more concise, neat, easier to implement

• would change the name of the 'Picture' model to the 'Post' model.

• further styling and building a profile for every user like on a real instagram
