PythonFront-endJavaScript
- By: Guillaume, CTO at Holberton School
- Weight: 2
- Project to be done in teams of 2 people (your team: Getacher Mitke, Bete Gorfneh)
- Project will start Oct 27, 2022 6:00 AM, must end by Oct 31, 2022 6:00 AM
- was released at Oct 28, 2022 6:00 AM
- Manual QA review must be done (request it when you are done with the project)
- An auto review will be launched at the deadline
For this project, we expect you to look at this concept:
Read or watch:
- Selector
- Get and set content
- Manipulate CSS classes
- Manipulate DOM elements
- Document ready
- Introduction
- GET & POST request
- HTTP access control (CORS)
At the end of this project, you are expected to be able to explain to anyone, without the help of Google:
- How cool it is to request your own API
- How to modify an HTML element style
- How to get and update an HTML element content
- How to modify the DOM
- How to make a
GET
request with JQuery Ajax - How to make a
POST
request with JQuery Ajax - How to listen/bind to DOM events
- How to listen/bind to user events
- You are tasked to come up with solutions for the tasks below yourself to meet with the above learning objectives.
- You will not be able to meet the objectives of this or any following project by copying and pasting someone else’s work.
- You are not allowed to publish any content of this project.
- Any form of plagiarism is strictly forbidden and will result in removal from the program.
- Allowed editors:
vi
,vim
,emacs
- All your files will be interpreted on Chrome (version 57.0)
- All your files should end with a new line
- A
README.md
file, at the root of the folder of the project, is mandatory - Your code should be
semistandard
compliant with the flag--global $
:semistandard *.js --global $
- All your JavaScript must be in the folder
scripts
- You must use JQuery version 3.x
- You are not allowed to use
var
- HTML should not reload for each action: DOM manipulation, update values, fetch data…
There should be one project repository per group. If you clone/fork/whatever a project repository with the same name before the second deadline, you risk a 0% score.

You will work on a codebase using Flasgger, you will need to install it locally first before starting the RestAPI:
$ sudo apt-get install -y python3-lxml
$ sudo pip3 install flask_cors # if it was not installed yet
$ sudo pip3 install flasgger
If the RestAPI is not starting, please read the error message. Based on the(ses) error message(s), you will have to troubleshoot potential dependencies issues.
Here some solutions:
$ sudo pip3 uninstall -y jsonschema
$ sudo pip3 install jsonschema==3.0.1
$ sudo pip3 install pathlib2
In your Vagrantfile
, add this line for each port forwarded
# I expose the port 5001 of my vm to the port 5001 on my computer
config.vm.network :forwarded_port, guest: 5001, host: 5001
if you need to expose other ports, same line but you will need to replace the “guest port” (inside your vagrant) and your “host port” (outside your vagrant, used from your browser for example)
It’s important in your project, to use the AirBnB API with the port 5001
It is your responsibility to request a review for this project from a peer before the project’s deadline. If no peers have been reviewed, you should request a review from a TA or staff member.

A new codebase again? Yes!
For this project you will fork this codebase:
- Update the repository name to
AirBnB_clone_v4
- Update the
README.md
:- Add yourself as an author of the project
- Add new information about your new contribution
- Make it better!
- If you’re the owner of this codebase, create a new repository called
AirBnB_clone_v4
and copy over all files fromAirBnB_clone_v3
- If you didn’t install Flasgger from the previous project, it’s time!
sudo pip3 install flasgger

- GitHub repository:

Write a script that starts a Flask web application:
- Based on
web_flask
, copy:web_flask/static
,web_flask/templates/100-hbnb.html
,web_flask/__init__.py
andweb_flask/100-hbnb.py
into theweb_dynamic
folder - Rename
100-hbnb.py
to0-hbnb.py
- Rename
100-hbnb.html
to0-hbnb.html
- Update
0-hbnb.py
to replace the existing route to/0-hbnb/
If 100-hbnb.html
is not present, use 8-hbnb.html
instead

One problem now is the asset caching done by Flask.
To avoid that, you will add a query string to each asset:
In 0-hbnb.py
, add a variable cache_id
to the render_template
. The value of this variable must be an UUID (uuid.uuid4()
)
In 0-hbnb.html
, add this variable cache_id
as query string to each <link>
tag URL

For the moment the filters section is static, let’s make it dynamic!
Replace the route 0-hbnb
with 1-hbnb
in the file 1-hbnb.py
(based on 0-hbnb.py
)
Create a new template 1-hbnb.html
(based on 0-hbnb.html
) and update it:
- Import JQuery in the
<head>
tag - Import the JavaScript
static/scripts/1-hbnb.js
in the<head>
tag- In 1-hbnb.html and the following HTML files, add this variable cache_id as query string to the above
<script>
tag
- In 1-hbnb.html and the following HTML files, add this variable cache_id as query string to the above
- Add a
<input type="checkbox">
tag to theli
tag of each amenity - The new checkbox must be at 10px on the left of the Amenity name
- Add to the
input
tags of each amenity (<li>
tag) the attributedata-id=":amenity_id"
=> this will allow us to retrieve the Amenity ID from the DOM - Add to the
input
tags of each amenity (<li>
tag) the attributedata-name=":amenity_name"
=> this will allow us to retrieve the Amenity name from the DOM
Write a JavaScript script (static/scripts/1-hbnb.js
):
- Your script must be executed only when DOM is loaded
- You must use JQuery
- Listen for changes on each
input
checkbox tag:- if the checkbox is checked, you must store the Amenity ID in a variable (dictionary or list)
- if the checkbox is unchecked, you must remove the Amenity ID from the variable
- update the
h4
tag inside thediv
Amenities with the list of Amenities checked

Before requesting the HBNB API, it’s better to know the status of this one.
Update the API entry point (api/v1/app.py
) by replacing the current CORS CORS(app, origins="0.0.0.0")
by CORS(app, resources={r"/api/v1/*": {"origins": "*"}})
.
Change the route 1-hbnb
to 2-hbnb
in the file 2-hbnb.py
(based on 1-hbnb.py
)
Create a new template 2-hbnb.html
(based on 1-hbnb.html
) and update it:
- Import the JavaScript
static/scripts/2-hbnb.js
in the<head>
tag (instead of1-hbnb.js
) - Add a new
div
element in theheader
tag:- Attribute ID should be
api_status
- Align to the right
- Circle of 40px diameter
- Center vertically
- At 30px of the right border
- Background color #cccccc
- Attribute ID should be
- Also add a class
available
for this new element inweb_dynamic/static/styles/3-header.css
:- Background color #ff545f
Write a JavaScript script (static/scripts/2-hbnb.js
):
- Based on
1-hbnb.js
- Request
http://0.0.0.0:5001/api/v1/status/
:- If in the status is “OK”, add the class
available
to thediv#api_status
- Otherwise, remove the class
available
to thediv#api_status
- If in the status is “OK”, add the class
To start the API in the port 5001:

Replace the route 2-hbnb
with 3-hbnb
in the file 3-hbnb.py
(based on 2-hbnb.py
)
Create a new template 3-hbnb.html
(based on 2-hbnb.html
) and update it:
- Import the JavaScript
static/scripts/3-hbnb.js
in the<head>
tag (instead of2-hbnb.js
) - Remove the entire Jinja section of displaying all places (all
article
tags)
Write a JavaScript script (static/scripts/3-hbnb.js
):
- Based on
2-hbnb.js
- Request
http://0.0.0.0:5001/api/v1/places_search/
:- Description of this endpoint here. If this endpoint is not available, you will have to add it to the API (you can work all together for creating this endpoint)
- Send a
POST
request withContent-Type: application/json
and an empty dictionary in the body - cURL version:curl "http://0.0.0.0:5001/api/v1/places_search" -XPOST -H "Content-Type: application/json" -d '{}'
- Loop into the result of the request and create an
article
tag representing aPlace
in thesection.places
. (you can remove the Owner tag in the place description)
The final result must be the same as previously, but now, places are loaded from the front-end, not from the back-end!

Let’s add a new feature: show and hide reviews!
Replace the route 100-hbnb
to 101-hbnb
in the file 101-hbnb.py
(based on 100-hbnb.py

“Reviews” with value “show” (add all necessary attributes to do this feature)
Write a JavaScript script (static/scripts/101-hbnb.js

- When the
span
next to the Reviewsh2
is clicked by the user:- Fetch, parse, display reviews and change the text to “hide”
