Using Forms with Flask - Facebook Lab

Objective:

In this lab, you will learn about taking and processing information, given by a user via HTML forms!

Before we start, make sure to fork the repo and clone the code.

Instructions:

As you can see, in the code we provided, you have a ready app.py (Flask app), login.html, home.html and `home.html files, these will be the files you will edit this lab. Explore the project files to have a better understanding of what's going on, even try to run the app!
It should look something like this:

First things first, in the top of app.py, you have some variables configured. Feel free to edit them according to your own preferences. The variables looks something like this:

username = "llo2ay"
password = "123"
facebook_friends=["Loai","Yonathan","Adan", "George", "Fouad", "Celina"]

1. Editing the login route in app.py, and the login form in login.html. It should:

   • Take input in the form, and process it in login route.
   • You should check if it's a POST request:
     • If it is, check for credentials. (if the username and password from login.html match the username and password variables)
     • If they match, you should proceed to home.html.
     • Make sure to update the <form> attributes (method and action) accordingly.
   • If it's a GET request. you should stay on the login.html page to try again.
     • Remember: GET is the default method.

2. Create/Define a new route in app.py and call it home.

   • You should link home route to home.html.
   • Checkpoint! Test out your website, make sure it works properly.

3. Using facebook_friends list, pass it to home.html using the home function/route in app.py.

   • Replace the current "friends" in the page with a for loop that loops through this list.
   • Costumize/Edit facebook_friends list and add your classmates/family members.
   • Run your app. Show your friends/family members.

4. Now, let's add a variable route called friend_exists with name as an input:

   • You should create a new route, called /friend_exists that additionally takes a variable in the route called name, for example - /friends_exists/Fouad.
   • The route should render friend_exists.html.
   • Make sure that this route accepts GET and POST as methods.
   • Add a link to each "friend" in home.html (facebook_friends list).
   • Make the link the route friend_exists and the name of the friend.
   • The function checks if the name is in the facebook_friends and displays True or False according to the results in 'friend_exists.html`.

Great job!

If you have extra time, continue to the Bonus Problems below.
If not, make sure your code is saved in Repl.it!

Bonus Problems:

1. When you login, is the username case sensitive? If not, fix these issues so your app could work properly.

2. Add a dictionary of usernames and passwords, accounts that are allowed to log in to your Facebook app.

3. Instead of friend_exists/{{name}}, make the link to each "friend" in home.html (facebook_friends list), that when clicked, it should Google the name.

• In other words, if you click on "Loai", it should take you to the results google page when searching for "Loai".

4. If you have extra time, complete yesterday's (or any other) lab(s) if you haven't yet!
