A: Modify the HTML File: MyFamilyHistory.html 1. 1.Set the action attribute in to: 1.Name all necessary widgets. For example 1.Insert the list of people (string %listOfPeople%) Copy MyFamilyHistory.html HTML_CS S Server1 YourAccountName

B: Set up the cgi file Copy the MFH.cgi file from HTML_CSS folder to the Server1 folder Copy MFH.html HTML_CS S Server1

C: Set up the Database – Step 1 1. Modify initializeWithNames.py so that it has your names Run createDB.py and initializeWithNames.py by double clicking on them, in that order Copy createDB.py HTML_CS S Server1 initializeWithNames.py

C: Set up the Database – Step 2 2.Modify MFH.cgi to include theses four lines at the end: openDB() {Opens External DB; copies names to Internal DB} processForm() {Adds/Deletes names to/from Internal DB} print generateHTMLPage(variables) {Generates new html page to be sent back to Client} closeDB() {Copies names from Internal DB to External DB} Add the following python constructs for the Internal DB: names = [] {[] defines names as an empty list} mothers = {} {{} declare mothers and fathers as fathers = {} empty dictionaries}

C: Set up the Database – Step 3 3. Modify MFH.cgi to read and write from the database: Insert the line “import squlite3” Insert the functions openDB() and closeDB():

D: Making life easier (use a dictionary) Organize the keywords with the text that is to replace the keywords in the html document using a dictionary. To define and initialize this dictionary put the following in the cgi file right after the cgitb.enable() statement: variables ={"%newName%": "", "%errorMessageArea%": "", "%listOfPeople%": "”}

E: Processing the Form – Step 1 1. Create the processForm() function called by the main routine and insert it after the openDB() function

E: Processing the Form – Step 2 2. Create the addPerson() function called by the function processForm() function

E: Processing the Form – Step 3 3. Create the deleteSelectedPerson() function called by the function processForm() :

E: Processing the Form – Step 4 4. Create the createListOfPeople() function called by the function processForm() :

F: Modify the generateHTMLPage function Modify the generateHTMLPage() function to replace the keywords %newName%, %errorMessageArea% and %listOfPeople% in the html document with the corresponding values in the dictionary in variables. Do this using the replace method:

G: Test it and link it up Make sure the “Add Person” and the “Delete Person” buttons work. Also make sure that a list of names now appears in the selection list.
