Engelsystem GSoC 2016 Summary

This blog post I would like to share my work done during the GSoC period (May – August). Doing GSoC has been one of the most wonderful experience in my life.


ENGELSYSTEM – Engelsystem is a volunteer management application for events written in PHP. It is used for coordination among different angels who want to volunteer.



  • It will make it easy for them to coordinate with the volunteers by the product we developed.


  • Those who want to volunteer finds it difficult to coordinate, contact admins. This platform helps all those who want to help.
  • Volunteers can register and can allot their shifts. A better User Interface, Integration with different Asian languages will allow the system to be used globally and in their local languages and ease for the volunteers to use.

As a part of the project I developed many new features for engelsystem. Implemented a workflow similar to wordpress, Implemented MVC model, Importing user data to database directly through script, Implemented a copy function for shifts, sending messages to entire group/ AngelType, Implemented a search for all Angels View, Date Picker for shifts, New Settings Page for admin where we can write event related information, Deployed the system on different platforms, Added Documentation, Re-factor the code, Improved the code standards, Blog Post tutorials on various technologies.

I am really happy with the outcome of the project. I learnt lot of new technologies and was improving day by day.

My initial proposal, time line of the project

My GSOC 2016 Proposal.

I have proposed a many UI changes for the system, Improving Documentation, Refactoring. All of these are done during the period. And I have implemented extra features and surpassed the proposal.

I have finished most of the proposed features before the Mid Evaluation. There was a shift in the timeline but I am very happy that the outcome was excellent. I was able to finish all the issues assigned to me on time.

What I have done to make Engelsystem better?

Daily Timeline during GSOC.

Everyday we need to write a scrum report about our progress and submit it before 10 AM local time. Scrum consists of the following information.

1.What did you do yesterday? (which areas, issues you worked on, links)

2.What do you plan to do today? (which areas, issues you want to work on, links)

3.What is currently preventing you from achieving your goals? What blockers do you encounter?

I have written total of 99 scrum reports from May 10 – August 23. I have never missed a scrum report.

My Activity on Engelsystem Google Group : https://groups.google.com/forum/#!forum/engelsystem

Working Environment

All the issues for engelsystem are available on github. Whenever we need to implement a new feature or resolve a bug we need to make a issue and start working on it.

There are 15 milestones for the project starting from May 10 – August 28th.

For discussions we need to use slack and google groups.

Engelsystem Features

Implemented work flow similar to wordpress.

wordpress has a famous 5 minute installation flow. We need to implement it for our project engelsystem.

Implemented the following tasks as a part of the workflow:

  • Changed engelsystem/config/config.default.php to engelsystem/config/config-sample.default.php.
  • Installation script where admin can define name and email at the beginning
  • Script to import tables directly
  • Instructions to Configure document root.
  • Documented the new flow in a blog post and in all installation readme’s

As part of flow similar to wordpress. I have created a script which directly imports the tables. Initially user need to do it through mysql.

Implement MVC Model

  • Initially the code has no clear MVC model. There were code in pages which is a mix of model and controller.
  • We need to remove the pages directory and move them to controller and model.
  • There were 26 pages. Created model files and controller files for the pages. Now the code structure is in clear MVC model.

Import user data from a spreadsheet

  • For FOSSASIA events we will be having lots of user data. If we can import the user data to engelsystem then it will very useful.
  • Implemented a script where admin just needs to browse a csv file containing data and information will be imported successfully

Implemented Search in All Users View

  • In All Users Page admin can view all the user information. If there are many users and admin wants to search for a particular name/field it becomes difficult.
  • I Implemented a search which makes it easy for admin to search any user.
  • We can search an user by any field like name, organisation, github username etc.

Deployed Engelsystem to Heroku

  • Heroku: Heroku is a cloud application platform – it is used to build and deploy web apps.
  • We need not worry about dependencies and testing. We can directly deploy a branch to heroku and test code whenever there is a new feature or new code added.
  • An automatic test deployment for engelsystem from the development branch is http://volunteersys.herokuapp.com

Viewing the shifts in respective time zone

  • Initially the user views all the shifts in server timezone.
  • Shifts should be shown to the volunteers/ angels in their respective time zone to avoid confusion.
  • Now User gets an option to select a time zone and view it in the respective time zone.
  • User needs to select the timezone while registering or change it in the settings page.

Database migrations with Phinx

  • Database migrations can transform your database in many ways such as creating new tables, inserting rows, adding indexes and modifying columns.
  • It avoids the use of writing MYSQL by hand and instead offers a powerful API for creating migrations using PHP code.
  • Implemented database migrations for update.sql file.

Unit Tests for php files

Writing unit tests

I have written unit test for PHP files using PHPUnit. With PHPUnit, the most basic thing you’ll write is a test case. A test case is just a term for a class with several different tests all related to the same functionality.This is an example unit test for AngelType_model.php

Localization – Viewing your site in different languages

Advantages of Localisation : It will also allow the system to be used globally on a large scale. As a part of this project I have implemented localisation in couple of languages.User can select I of the languages and the total information will be available in that language.

Code Quality and Refactoring


  • Refactoring is very important to maintain code standards.
  • After implementing MVC model all the model files have duplicate and unorganised code. Refactored the code based on table it is accessing.
  • It will make any user easily find the function and create in the respective table.

Maintaining code quality:

  • When we add new code we need to explain what a particular variable is and what are the parameters of a function.Added comments to the code and function created. It will help new developers to easily understand the code.

As much as we code we need to document. For good software we need to have good documentation also. Added several documentation about installation, setup, configuration, features.

Added the following Documents during May-August

Blog Posts

It’s very important for us to share our knowledge to entire world. The easiest way to do this is by blog posts.

I have written 15 blogs posts during May-August on wide variety of topics.
