Weeks 08_09 Lab, 2018 S2

Due: Sunday, 11:59 pm, Week 09

Aim

Develop skills to build a Flask front-end and authentication using Flask Login

Lab instructions

In this lab, you will be implementing part of a FLASK front-end for the car rental system that you

had worked on in week 7. A substantial amount of starter code has been provided for this lab.

You should import this from the Github application used throughout the course

(https://cgi.cse.unsw.edu.au/~cs1531/github/run.cgi/)

When you first import it, you should have a look at what has been provided to you and see where

you have to make changes. Comments have been provided where you need to provide your code.

Your main task is to link the application together (Flask front-end and back-end logic). You must

complete this task individually.

Task 1: Implementation of Flask Login Authentication Module (2 marks)

For this exercise, you will implement a simple authentication module using Flask Login. Carry out the

following tasks:

a. Install the required files

1. In your virtual environment, install the necessary flask plug-ins by typing:

pip3 install –r requirements.txt

b. Implement the flask login route

For this task, you are required to implement the flask route

@app.route('/login', methods=['GET', 'POST'])

as marked in the comments as Task 1. The necessary view components are already provided to you. The

function to validate the authentication details (‘user-name and password’) is also provided in

CarRentalSystem.py

Task 2: Implement the use-case “search for a car by name and model” (4 marks)

For this task, you need to implement the use-case to “search for a car by name and model”.

Once you have logged in with a valid user-name and password, you are taken to a page that has a

link, “search cars”. This launches a page with a list of all cars currently being used by the car rental

system. At the top, you will see a filter with two search fields for “make” and “model” that allows

you to search for cars by a specified “make” OR “model” e.g., when you specify a “make” e.g.,

Honda and click on search, this should load a page to display all the cars in the rental system that

match the specified make as shown below.

Your task is to implement the logic for this filter search. For this task, you will need to carry out

two sub-tasks:

implement the function def car_search(self, name=None, model=None): in the file

CarRentalSystem.py (2 marks)

implement the route @app.route('/cars') in the Flask routes file routes.py to carry out the

necessary search using the function above and pass the results to be displayed to the search page

cars.html which has been provided to you. (2 marks)

Task 3: Implement the use-case “search all car bookings” (4 marks)

For this task, you need to implement the use-case to “list all bookings for a car”. Clicking

on any of the cars on the search result above, loads a page with details about the car. At the

bottom of the page, two buttons are displayed. The button Book enables a new booking to be

created for the car which has already been implemented. The second button See All Bookings

shows a list of current bookings for the car which is to be implemented by you. For this task, you

will need to carry out two sub-tasks:

implement the route @app.route('/cars/bookings/<rego>’) in the Flask routes file

routes.py to retrieve the current bookings for a car and pass the results to be displayed

to the search page bookings.html which you have to implement. (2 marks)

implement the search page route bookings.html which will display the bookings as

described above. The skeleton file is provided to you. (2 marks)

Bonus Task: Implement the Admin System (4 marks)

For this task, you need to implement a simplified solution to the admin use-cases “Add new Car” and

“Generate Rental Report”. On the login page, a separate form for logging-in as an admin is provided.

For this task, you will need to carry out three sub-tasks:

Implement the route @app.route('/login_admin’) in the Flask routes file routes.py

to enable admin users to login using their credentials (1 mark)

Implement the route @app.route('/cars/bookings’) which should display the list of

all current bookings on the system (1 mark)

? Implement the route @app.route('/add_car’) which should allow admin users to

register new cars to the system, using the method provided in CarFactory.py.

Also, provide a meaningful message to the user upon successful car registration,

by making changes to the given car_register_form.html file. (2 marks)

Testing the implementation

You have been provided with some test data to demonstrate your implementation. Once you have

implemented the above tasks, test your implementation with the provided test-data.

Marking

To obtain a mark for this lab you will need to demonstrate:

Upload completed solution by Sunday, week 09 to GitHub (before mid-sem break)

Demonstrate successful implementation of tasks 1, 2 and 3 to your tutor in week 10 lab session

(after mid-sem break)

Please note, students on the Monday lab, as Monday is a public holiday, you have an alternative labtime

scheduled just for this week. Please refer to the course time-table for exact time and location

of week 10 lab.
