Transcribed Image Text:

In this TMA, you will develop a prototype application to help ERP participants create their "Order". To reduce complexity, ERP enrolment is out-of-scope, instead MOH will provide the participant list via a text file (Appendix A). Deduction of CDC vouchers/digital wallet is out-of-scope. However, your prototype application must produce the order file (Appendix C), so that ERP's partners and CDC can process accordingly. Question 5 (30 marks) In this question, you will implement the EatRightAdmin class and the prototype application focusing on the creation of "Order". You need to make use of the classes created in the previous questions. As ERP is a pilot programme, the EatRightAdmin class is to ensure that a participant can only submit up to 2 orders per day. This EatRightAdmin class will also contain the collections of participants, available Delis and information of orders submitted. Figure Q5 highlight the class diagram for EatRightAdmin EatRightAdmin _DAILY_QUOTA: 2 _participants: dictionary of Participant objects _delis: dictionary of Deli objects _orders: list _init__(self) setupParticipants(self): dictionary setupDelis(self): dictionary readOrders(self): list searchParticipant(self, id: str): Participant searchDeli(self, code): Deli listDelilnventory(self): str countOrders/self, id: str): int listOrders(self, id: str); str addOrder/self, participant: Participant, deliSet: DeliSet): Order saveOrders(self) Figure Q5 Implement the EatRightAdmin class. There is ONE class variable: DAILY QUOTA which is 2, representing the number of orders a participant can submit per day. There are THREE instance variables: o participants (dictionary): collection of ERP participants. The key for this dictionary is the participant's ID, and the value is the Participant object. o _delis (dictionary): collection of delis that ERP is offering. The key for this dictionary is the Deli code, and the value is the Deli object. o_orders (list): this is a list of Order objects, whereby the initial Order objects are created by reading the order information as shown in Appendix C. Constructor performs the following: o Invoke the setupParticipants method to setup Participant objects into the dictionary by reading the information from "Participants.txt". o Invoke the setupDelis method - to setup the Deli objects into the dictionary using the information provided in "Delis.txt". Invoke the readOrders method- to load the Order objects created (for next day) into a list. o Invoke the class method of Order: setNextID, so that the next order ID will continue from the last order created (if exists). Method setup Participants reads the information from "Participants.txt" to setup the ERP participants into the dictionary participants. See Appendix A for file content and format. Method setupDelis reads the information from "Delis.txt" to setup all the Delis currently offered by ERP into the dictionary _Delis. See Appendix B for file content and format. Method readOrders will attempt to find the order file for the next day (filename format "Order_YYYYMMDD.txt") and create an Order object before adding into the list_orders. File content is described in Appendix C. If the order file is not found, manage this exception, and initialise_orders to an empty list. Search for the correct Participant and Deli objects to create the Order object. Given an id as parameter, the method searchParticipant searches and returns the Participant object matching this id. If not found, the method returns None. Given a code as parameter, the searchDeli method searches and returns the Deli object that matches the parameter. If there is no such Deli, the method returns None. listDelilnventory method formats and returns the string representation of all Deli objects, concatenated and one Deli object per line.

This method searches and returns the number of orders that has participant's id matching the parameter id. If there is no match, the method returns 0. The list Orders method has 1 parameter: id. This method will perform the following: Search for the participant using the given id. o If no such participant, then method should raise ERPException with proper message "You did not sign-up for this programme..." If participant is found, invoke the countOrders method. If there is no order, raise ERPException with message "You did not order any DeliSet..." (b) . If there are orders, the method formats and returns the order information, one per line: Your order(s) for 2023-08-26: =========== Order ID: 20230826001 ID: 54096807E Name: Wong Yong Heng Deliset: My Breakfast Price: $7.00 with Croissant, Smoked Duck Salad, Banana Pancakes Discounts: $1.00 Delivery Fee: $0.00 Final Price: $6.00 Order ID: 20230826003 ID: 54896807E Name: Wong Yong Heng Deliset: Heng Heng Snack Age: 83 Price: $3.50 with Chocolate Cake, Beetroot Raita Discounts: $1.00 Delivery Fee: $0.00 Final Price: $2.50 Consume in 1.5 hrs Age: 83 Consume in 0.5 hrs The addOrder method has a Participant object and a DeliSet object as parameters. This method is invoked when the participant is ready to create Order with the DeliSet. The following tasks need to be performed: o Check that the participant will not break the DAILY QUOTA, with this new order. If yes, this method should raise ERPExcpetion with message "You cannot exceed the daily quota...." If there is no exception, then proceed to: o Create the new Order object, with the given parameters. o Append this new Order object to the instance variable_orders. o Return the Order object. Healthier SG: Est-Right Programme 1. Order Deliset 2. List Orders 3. Quit The saveOrders method will write the return value of the getDetails method of the Order objects in the list _orders into the order file for next day. The file format is defined in Appendix C. There is no need to create the order file if there is no order. (18 marks) Write an application that allow ERP participants to submit and enquire their orders. As this is a pilot programme, the deduction of CDC vouchers/digital wallet will be out-of- scope. Instead, your application must provide the orders' information (Appendix C), so that ERP's partners and CDC can process manually. Before presenting the below menu, your application should create the EatRightAdmin object, so that the participants, delis, and any existing orders can be loaded. Enter choice: The next few paragraphs will explain the 3 options in detail. Option 1: Order DeliSet To order a DeliSet, the following steps and data elements should be collected: Prompt for participant id to help locate the Participant object. o If participant has enrolled in ERP, print his/her eligible discounts. o If there is no such participant, display appropriate message and return to menu.

To reduce complexity, ERP enrolment is out-of-scope, instead MOH will provide the participant list via a text file (Appendix A). Deduction of CDC vouchers/digital wallet is out-of-scope. However, your prototype application must produce the order file (Appendix C), so that ERP's partners and CDC can process accordingly. Question 5 (30 marks) In this question, you will implement the EatRightAdmin class and the prototype application focusing on the creation of "Order". You need to make use of the classes created in the previous questions. As ERP is a pilot programme, the EatRightAdmin class is to ensure that a participant can only submit up to 2 orders per day. This EatRightAdmin class will also contain the collections of participants, available Delis and information of orders submitted. Figure Q5 highlight the class diagram for EatRightAdmin EatRightAdmin _DAILY_QUOTA: 2 _participants: dictionary of Participant objects _delis: dictionary of Deli objects _orders: list _init__(self) setupParticipants(self): dictionary setupDelis(self): dictionary readOrders(self): list searchParticipant(self, id: str): Participant searchDeli(self, code): Deli listDelilnventory(self): str countOrders/self, id: str): int listOrders(self, id: str); str addOrder/self, participant: Participant, deliSet: DeliSet): Order saveOrders(self) Figure Q5 Implement the EatRightAdmin class. There is ONE class variable: DAILY QUOTA which is 2, representing the number of orders a participant can submit per day. There are THREE instance variables: o participants (dictionary): collection of ERP participants. The key for this dictionary is the participant's ID, and the value is the Participant object. o _delis (dictionary): collection of delis that ERP is offering. The key for this dictionary is the Deli code, and the value is the Deli object. o_orders (list): this is a list of Order objects, whereby the initial Order objects are created by reading the order information as shown in Appendix C. Constructor performs the following: o Invoke the setupParticipants method to setup Participant objects into the dictionary by reading the information from "Participants.txt". o Invoke the setupDelis method - to setup the Deli objects into the dictionary using the information provided in "Delis.txt". Invoke the readOrders method- to load the Order objects created (for next day) into a list. o Invoke the class method of Order: setNextID, so that the next order ID will continue from the last order created (if exists). Method setup Participants reads the information from "Participants.txt" to setup the ERP participants into the dictionary participants. See Appendix A for file content and format. Method setupDelis reads the information from "Delis.txt" to setup all the Delis currently offered by ERP into the dictionary _Delis. See Appendix B for file content and format. Method readOrders will attempt to find the order file for the next day (filename format "Order_YYYYMMDD.txt") and create an Order object before adding into the list_orders. File content is described in Appendix C. If the order file is not found, manage this exception, and initialise_orders to an empty list. Search for the correct Participant and Deli objects to create the Order object. Given an id as parameter, the method searchParticipant searches and returns the Participant object matching this id. If not found, the method returns None. Given a code as parameter, the searchDeli method searches and returns the Deli object that matches the parameter. If there is no such Deli, the method returns None. listDelilnventory method formats and returns the string representation of all Deli objects, concatenated and one Deli object per line.

This method searches and returns the number of orders that has participant's id matching the parameter id. If there is no match, the method returns 0. The list Orders method has 1 parameter: id. This method will perform the following: Search for the participant using the given id. o If no such participant, then method should raise ERPException with proper message "You did not sign-up for this programme..." If participant is found, invoke the countOrders method. If there is no order, raise ERPException with message "You did not order any DeliSet..." (b) . If there are orders, the method formats and returns the order information, one per line: Your order(s) for 2023-08-26: =========== Order ID: 20230826001 ID: 54096807E Name: Wong Yong Heng Deliset: My Breakfast Price: $7.00 with Croissant, Smoked Duck Salad, Banana Pancakes Discounts: $1.00 Delivery Fee: $0.00 Final Price: $6.00 Order ID: 20230826003 ID: 54896807E Name: Wong Yong Heng Deliset: Heng Heng Snack Age: 83 Price: $3.50 with Chocolate Cake, Beetroot Raita Discounts: $1.00 Delivery Fee: $0.00 Final Price: $2.50 Consume in 1.5 hrs Age: 83 Consume in 0.5 hrs The addOrder method has a Participant object and a DeliSet object as parameters. This method is invoked when the participant is ready to create Order with the DeliSet. The following tasks need to be performed: o Check that the participant will not break the DAILY QUOTA, with this new order. If yes, this method should raise ERPExcpetion with message "You cannot exceed the daily quota...." If there is no exception, then proceed to: o Create the new Order object, with the given parameters. o Append this new Order object to the instance variable_orders. o Return the Order object. Healthier SG: Est-Right Programme 1. Order Deliset 2. List Orders 3. Quit The saveOrders method will write the return value of the getDetails method of the Order objects in the list _orders into the order file for next day. The file format is defined in Appendix C. There is no need to create the order file if there is no order. (18 marks) Write an application that allow ERP participants to submit and enquire their orders. As this is a pilot programme, the deduction of CDC vouchers/digital wallet will be out-of- scope. Instead, your application must provide the orders' information (Appendix C), so that ERP's partners and CDC can process manually. Before presenting the below menu, your application should create the EatRightAdmin object, so that the participants, delis, and any existing orders can be loaded. Enter choice: The next few paragraphs will explain the 3 options in detail. Option 1: Order DeliSet To order a DeliSet, the following steps and data elements should be collected: Prompt for participant id to help locate the Participant object. o If participant has enrolled in ERP, print his/her eligible discounts. o If there is no such participant, display appropriate message and return to menu.
