RubyMVC

RubyMVC is a lightweight web application framework written in Ruby, inspired by Ruby on Rails/ActiveRecord

About

Based on the MVC software architectural pattern, with RubyMVC you can build and run a simple, lightweight, full-stack web application! Generate models in ruby that represent your relational DB (Either PostgreSQL or SQLite are supported) data - supports belongs_to, has_many, and has_many_through assocations. Use the Controller class to serve static assets, render HTML, or embed your data in an ERB template. Use the Session class to handle cookie or flash data. Define routes with the Router class to construct a robust API that parses arbitrarily nested query parameters into a Hash object with indifferent access (as string or symbol).


Web Sketch App - PAINT

This repo contains the source code for RubyMVC along with a simple web-app demo. With it you can create PNG sketches in your browser using the customizeable color swatch and canvas, then save them to the DB of your choice (PG or SQLite) and view them in the home page gallery along with their metadata (author, title, and date of creation). The UI was built using jQuery.

Instructions to run

If you would like to run this web application locally, you must be using ruby 2.3.4, and have PostgreSQL. The png images you create are uploaded to cloudinary.com, so you must have an API key to use it. It's free to create a cloudinary account for personal usage. Once you have your cloud name, api_key and api_secret from cloudinary, paste them into the shell script start.sh at the root of this repository.

PostgreSQL

The following instructions are for PG DB, and assume it is running on your local host on default port 5432.

# login to postgres cli from terminal:
$> psql

# create database:
psql> CREATE DATABASE rubymvc;

# connect to database:
psql> \c rubymvc;

# create sketch table:
psql> CREATE TABLE sketch(
  id SERIAL PRIMARY KEY,
  author VARCHAR(255) DEFAULT 'Anonymous' NOT NULL,
  title VARCHAR(255) DEFAULT 'Untitled' NOT NULL,
  image VARCHAR(1024) NOT NULL,
  created_at TIMESTAMP DEFAULT NOW()
);

# exit postgres command line utility:
psql> \q

# install ruby dependencies (from terminal):
$> bundle install

# run web app (after pasting cloudinary info inside start.sh where indicated):
$> sh start.sh

Alternatively, you can use your own postgres server and use the DATABASE_URL variable when running the script to start the app, ie:

$> DATABASE_URL=postgresql://username@127.0.0.1:5432/rubymvc sh start.sh

Once it's up an running, point your browser to http://localhost:3000/sketches/new
