AirBnB Clone- Part. 1: building the console. (introduction)

This is one of the major projects in the ALX Software Engineering program. It is the first web application that you will build as an ALX student. It involves the practical application of proficiency in the foundational concepts emphasized in the ALX high-level programming track to clone the AirBnB website.

However, the project is subdivided into various components, including:

• AirBnB clone - The Console

• AirBnB Clone - Web static

• AirBnB Clone - MySQL

• AirBnB Clone - Deploy static

• AirBnB Clone - Web framework

• AirBnB Clone - RESTful API

• AirBnB Clone - Web Dynamic

But I'm only going to share with you now the first one which is AirBnB clone - The Console.

How we conquered the task

The project is to be done in a group of two people per team or you can choose to do it alone, but I'll advise you to find a good partner. In the ALX setting, project execution typically follows a task-oriented structure. Specifically, for this project, we addressed a total of 18 distinct tasks. The advantage of this task-based approach lies in its ability to break down the entire project into manageable components, allowing us to focus on and resolve each task individually.

It is a seven-day project, that sounds like much time, right? but I tell you it's not. I found a partner and we started by using the first day to go through the whole concepts of the project and how we can work together to solve the tasks. So we started the project by addressing each task one after the other. The first few tasks were relatively straightforward, setting a positive tone for the project.

For each task, we were provided test cases so we used that to check our code to make sure we were on the right track.

We were flowing very much with the tasks until we got to task 8 we really couldn't find what the problem was but we knew it was from our previous implementations. Then we went back to our code cause we weren't even sure where it was, but we eventually figured it was from our implementation of the cmd interpreter.

We successfully navigated through almost all the tasks when the checker was released (the software used by ALX for project evaluation) Frustration ensued as our functional code didn't meet several unspecified requirements, leaving us puzzled about the specific criteria we were falling short on.

We figured it out by going through the steps and how we implemented it one after the other again. Rounding up the tasks, our last implementation caused us to lose our first deadline marks we found out we didn't add a semicolon while defining a method we didn't notice cause we didn't test after implementing it.

Now, let's delve into the details of the project.

A concise look into the project's console functionality

The console serves as a command interpreter, akin to Python's standard interactive shell or REPL. Operating through the command-line interface, it enables the execution of commands to interact with the web application. The console facilitates the manipulation of objects within the project, such as creating new users or places, retrieving objects from storage, performing operations like counting and computing statistics, updating object attributes, and handling object destruction when necessary. It plays a crucial role in debugging and testing, allowing for experimentation with the web application using different inputs.

In essence, "the console" provides a means to interact with and manage objects in the web application through command-based interactions.

Now, let's be precise about the objects of the web application I'm referring to.

In our Airbnb web application built in Python, entities are represented as objects, and instances of specific classes. For instance, a User class instance signifies an individual with an account, storing details like name, email, and password. Similarly, State and City class instances represent states and cities, respectively. The Place class instance embodies a temporary room or suite available for booking, holding information such as name, description, location, price, and availability dates. This object-oriented approach forms the foundation of our database structure, encapsulating diverse aspects of the booking process within distinct classes.

I'll break down the project into 4 main parts:

• Backend

• Frontend

• Storage

• Testing

The Backend

This requires proficiency in Python's Object-Oriented Programming (OOP) concepts, covering essential principles such as:

• Classes

• Objects

• Class and Instance attributes

• Methods

• Inheritance

Additionally, you should be well-versed in working with Python packages and modules, particularly in importing and utilizing them.

Two crucial modules for the project are:

1. UUID Module: Used for generating unique identifiers, understanding its implementation is vital for ensuring distinct identification within the application.

2. Datetime Module: Employed for handling date and time operations, familiarity with this module is necessary for managing temporal aspects in the web application.

Mastery of these modules is crucial for the successful execution of the project.

If you've explored Airbnb's website, you'll notice key functionalities that reflect user interactions. For instance, signing up is managed by the User class, while users can leave reviews and list places. Listing a place involves specifying the state and available amenities. In essence, your backend must seamlessly handle these actions.

The Frontend

To make your work accessible to users without direct code interaction, an interface is essential. In this project, the CMD module in Python is employed due to the fact that we haven't studied HTML, CSS, and Javascript, which are used for front-end web development.

To implement this, familiarize yourself with the CMD module.

The Storage

In our web development project, data storage is crucial. While databases are typically used, we utilized a JSON file due to our current stage of learning. To achieve this, it's essential to grasp the Python JSON Module, which facilitates data storage and retrieval in JSON format.

As part of using this module in the project, you need to learn about serialization and deserialization of Python objects.

The Test

There are a lot of Software Testing techniques but for this project, we are to use unittest.

Unit testing is a vital tool in software development, offering a proactive approach to identifying errors and bugs early in the development process. While it can be time-consuming and presents challenges, testing individual functions and methods ensures correctness. This practice prevents issues from escalating to more complex stages of application development, where troubleshooting becomes more intricate.

Keys to note for the project

1. Cmd Module

2. Interactive prompt handling

3. Command line editing

4. Command completion

5. uuid module

6. dateTime module

7. \args and \*kwags

8. Python packages

9. unit testing

Conclusion

I would love to keep going and sharing all the details but I don't think I'm allowed to do that. But I believe that this will be a good read for you if you have yet to go through this project.

I would keep documenting my progress in the ALX program. Do well by subscribing to my blog so you can be informed when I drop a new article and leave feedback. As that will motivate me to do more like this.
