Web Application Development 2
Group Project Web App (25%)
Introduction
The WAD2 Project is mainly based on the development of a web application of your
choosing. Your web application should be developed using Python, Django, HTML, CSS and
associated technologies including Javascript, JQuery and AJAX.
Implementation of your web app should draw on the skills built up during the development of
Rango. Teams are free to use their own ideas, however there are some basic expectations:
• the app should involve user authentication;
• it should certainly interact with some kind of model stored in a database;
• it should be visually appealing and have an intuitive user interface;
• overall the functionality supported should be rich enough in order to allow you to
demonstrate an understanding of the technologies listed above.
Beyond these guidelines, it is up to you, though if you do need some ideas, the following
section lists some example projects from previous years.
Example project ideas from previous years
• Rate My Beard
o Users with beards can upload photos inviting feedback; other users can login, view
photos and give feedback
• GU Grub Guide
o Users can leave ratings for restaurants and view other users’ ratings
• UnNoobMe
o Students seeking private tutors and tutors seeking clients are allocated to each other
• Does my MSP Represent Me?
o Users can find out information about how their MSP is voting in Parliament
• TripShare
o Users can post information about their upcoming trips, browse / search for trips and
request to join a specific trip
• Bargain Radar
o Small businesses can post their discounted deals; customers can browse deals and
add them to baskets
• SHAKESbeer
o Allows users to contribute cocktail recipes; users can browse and search over, and
rate and comment on, cocktails
• FilmBook
o Users can login and browse, search and rate movies; film producers can login and
upload new films so that they can be rated
• Federated Health Search Application
o People find out about particular conditions and to save the information that they find
into different folders. The app lets people search across two different medical sites
• Zombie Survival
o A game of search and survival. The web application needs to interface with a series of
classes that create the world in which the player needs to survive.
The last two projects are described in more detail in Appendix 2.

Working in a team
You should think about how the tasks associated with the development of your team’s web
app should be divided. Try to ensure that activities are assigned so that every member of the
team can be involved at all times. Here is a possible breakdown of responsibilities for a fourperson
team (this is just an example and you should feel free to organise things differently if
you prefer. Remember, contributions can also be balanced with earlier design work and the
forthcoming presentation):
1. user authentication, unit testing
2. models, Javascript, AJAX
3. views and URLs
4. templates and CSS
What should be submitted
You should host your application on PythonAnywhere and also ensure that the latest version
of the code is stored in a public GitHub repository. The URLs for both of these locations will
need to be submitted. You should ensure that your final application addresses the following
requirements:
Deployment
• Application is deployed via PythonAnywhere and runs from there
• Requirements file is included and contains the correct packages
o Within your main project folder you should include a file called requirements.txt that
can be used to install the relevant packages within a newly-created virtual environment
using pip install –r requirements.txt. You can create this file easily using pip
freeze > requirements.txt.
• Database / migrations files not included
o You should delete your database and migrations files so that when your tutor works on
deploying your application on his/her local machine, the database can be recreated
from scratch by making the relevant migrations and running your population script.
• Population script works and contains useful example data
o Create a population script called population_script.py with enough relevant data in
your main project folder.
• Application can be deployed on marker's own machine
Functionality
• Main functionality has been implemented (hopefully reflecting the design)
o Here you should refer back to your design specification to guide development towards
providing functionality consistent with what was envisaged.
o If you have used external sources, you should acknowledge them in a README file in
the top-level folder of your project. Failure to acknowledge external sources could
result in a deduction of marks under the “main functionality” heading.
o Although there are marks available for deploying your application on PythonAnywhere,
the main functionality will be checked with respect to the version that your tutor
deploys locally (i.e., the version on localhost).
• Application is bug-free / no error messages occur
o The user should be able to access all of the functionality of the application without
encountering Django error messages. You should thoroughly test your application to
ensure that this is the case.
• Application includes some Javascript / JQuery / AJAX
o Your application should not be based solely on Python and Django, and there should
be evidence of usage of one or more of some of the technologies covered later in the
course including Javascript / JQuery / AJAX.
4
Look and Feel
• Polished / refined interface, not clunky
• Uses a responsive CSS framework
o CSS can be quite fiddly – to help with the layout and appearance of your web pages
you are recommended to use a CSS framework such as Bootstrap.
• If browser window size changed, is the change handled neatly?
o In the “Look and Feel” category, marks are available for an attractive and intuitive user
interface with good use of CSS.
Code
• Templates inherit from base
• URLs are relative, i.e., use the {% url ..%} tag
• Code contains helper functions/classes (if required)
• Code is readable, clear and commented where appropriate
• CSS and Javascript are kept separate from templates (i.e., not inline)
• No repetition of code blocks in the views or templates
• Unit tests are included
o In the “Code” category, marks are available for well-organised code, adhering to the
principles that you will have learned during the development of the Rango app.
A sample marking scheme is included in Appendix 1.
Use of external sources
It is recognised that you may use external sources (e.g., Bootstrap) when developing your
application. However these must be acknowledged when you submit (see below).
How to submit
After developing your web application you should host it on PythonAnywhere and ensure
that the latest version of your code has been pushed to your team’s GitHub repo.
One member of the team should then submit a one-page document via the “Project”
submission icon on the Moodle page for the course, containing the following information:
• Name of web application
• Lab group number and team letter (e.g., Lab group 4, Team B)
• Team members (names and student numbers)
• GitHub URL for the app
• PythonAnywhere URL for the app
• Any external sources used (code, libraries, APIs), if applicable.
The person making the submission will be required to complete a Declaration of Originality
on behalf of all team members when submitting via Moodle. If you have used any external
sources, be sure to acknowledge them in your one-page document. For reference, the
School’s plagiarism policy is contained in Appendix A of the Undergraduate Class Guide.

Appendix 2: Example projects from previous years
In a previous year, there were four fixed project ideas and each team was required to select
and work on one of those four. Specifications from two of these are provided below. These
can help provoke your own ideas, and provide an example of the expected scope and
complexity of the apps to be created in the project.
Note that these are examples to illustrate sample ideas and that diagrams etc might
not be in the required format for any of your submissions
Federated Health Search Application
Description: The purpose of this application is to help people find out about particular
conditions and to save the information that they find into different folders. The application
lets people search across two different medical sites (medline and healthfinder) and the
general web (bing). People using the application would like to self-diagnose, i.e. given some
symptoms find out what are the likely conditions. They would also like to find out information
about particular conditions, treatments and medicines.
Specifications:
Searchers need to be able to:
• create an account and profile
• edit, update and maintain their profile
• create a category (where they can save pages that they found)
• save pages that they find during the process
• search for conditions, treatments, medicines.
• share a list of links (via a category)
o links and categories should be private, unless shared.
The search interface should provide:
• a mash up of results from the three search verticals
• tabs to enable access to the individual search verticals
• results should be annotated in terms of source (which vertical)
• a list of user defined categories should be available to select and browse
• an easy mechanism to save results to categories
• inline query suggestions to help uses with tricky words and spelling
When results are saved, the page should be fetched and stored. The readability of the page
should be calculated, using TextStat’s Flesch Reading Ease Score. The polarity and
subjectivity of the text should also be calculated, using TextBlob.
When looking at saved pages, the searcher should be able to see the title of the page, the
summary, the source, url, the reading score, polarity score and subjectivity score.
The API’s for the federated search are:
• http://healthfinder.gov/developer/How_to_Use.aspx
• https://www.nlm.nih.gov/medlineplus/webservices.html
• https://datamarket.azure.com/dataset/bing/search
Additional resources:
• https://pypi.python.org/pypi/textstat/0.1.4
• https://pypi.python.org/pypi/textblob/0.11.0
High level system architecture diagram:

HealthFinder, Medline and Bing are all external APIs. To provide some clarity I have split out
the Search component that will interface with these APIs. And then my middle ware will use
this service.

Zombie Survival: A Game of Search
Description: The purpose of this web application is to provide the frontend interface for a
game of search and survival. The web application needs to interface with a series of classes
that create the world in which the player needs to survive.
The game is as follows:
A player starts on day one of the zombie apocalypse. Their goal is to survive as long as
possible (as measured by the number of days).
Their party size is 1. They have 3 units of food and 2 units of ammunition.
They enter a street. A street contains a number of houses. Each house has a number of
rooms.
A room may contain other survivors, zombies, food and/or ammunition.
The player has a number of moves.
8
On the street:
(1) a player can choose which house they enter.
In a house:
(1) enter room
(2) move to next room
(3) leave house
In a room:
(1) search room
(2) leave room
(3) if zombies are present, they can fight or run.
a. if they run, they leave the house and return to the street
b. if they fight, they might lose the fight (lose party members), or win, in
which case they claim whatever is in the room (survivors, food, ammo)
c. the number of zombies killed is counted
The game mechanic for win/loss is based on the number of zombies, the amount of
ammo and the size of the party.
During a day, the player has X units of time. Each action costs time. The day ends when
they run out of time. At the end of the day, the game mechanic, decreases the amount of
food depending on the size of the party. If there is not enough food, then party members
might leave. Party size and food is updated, then they start the next day.
The web application needs to provide the following functionality.
Specifications:
Players need to be able to:
• create an account and profile
• view, edit, update and maintain their profile
• start a game and return back to a game in progress.
• Play the game according to the mechanics described above
• View the leaderboard
Visitors to the site:
• Need to be able to view the leaderboard
• Read the instructions of the game
• Be able to register
The profile contains the players handle/username and picture along with how many games
they have played, their average and best number of days survived and zombie kills. The
profile also lists the badges that the player has achieved.
Badges: there are 4 badges with different levels (bronze, silver, gold): (i) Survival: survived
5, 10 and 20 days. (ii) Killer: killed 10, 20 and 50 zombies in one game. (iii) Stamina: played
5, 10 and 20 games, (iv) Party: had a party size that contained 10, 20, 40 people.
Leaderboard: there are two leaderboards: (i) top 20 players based on days survived, (ii) top
20 players based on zombie kills.
As the application will use the Game Engine provide we have made this explicit in the
following high level system architecture diagram:
9
Here is an ER diagram:
We assume that a Player can only play one game at one time. Statistics on pasts games are
recorded in the Player model.
Since they can only be in one game at one time, we can store the game in the player model,
too.
Player(user, profile_picture, games_played, most_days_survived, most_kills, most_people,
current_game)
username, password, email, are stored in the django user model.
Current_game stored the current instantiated game (tip: use the python pickle package to
persist the game object, and save it in the Player model).
How the Badge is represented depends a lot on the implementation. My suggestion is
below, but other justifiable versions are acceptable, especially if they work in an elegant
fashion.
Badge( name, description, criteria, badge_type, level, icon)
Where badge_type (kills, people, days) and criteria is an integer specifying how many kills,
people, days, etc have to be obtained in order to get the badge.
Icon is an image that represents the badge. The population script should ensure that the
badges and their icons are all inserted into the database.
A class/handler is needed to determine if the criteria for a particular badge_type is met, or
not.
Achievement (player, badge, date_awarded)
