Ruby on Rails (aka Rails) is one of the most popular web application framework in the planet. It is designed to eliminate much of the drudgery of writing typical web applications by providing default settings that eliminate most configuration code (“convention over configuration”) and by providing a rich set of utility functions that make most common tasks simple. With Ruby as its core programming language – it makes it so much easier to write robust web applications that will scale as you need them to and be easy to maintain as you go forward.
This simple e-commerce application demonstrates CRUD operations using mongoDB and a simple implementation of a cookie based user authentication using Bcrypt. I specifically built this application to serve as a default template for building medium to large-scaled e-commerce applications.
This project is available for testing on Heroku. Unfortunately you wont be able to test the image upload as Heroku does not allow writing of files within their file system. Check out the demo
- Download the zip file
- Open your terminal then navigate to where you installed MongoDB. In my case it’s located under C:/mongodb/
- From the root directory of your Mongodb installation, go to bin folder then run: mongod.exe to initialize the Mongodb database server
- Open another terminal then navigate to where you extracted the project files.
- Run bundle install to install all project dependencies.
- Run the migration: rails db:migrate
- Finally run: rails server to start the Web Server.
- Open up your favorite browser then go to http://127.0.0.1:3000
