Introduction

As a book lover, keeping track of the new books you acquire can be a daunting task. With the rise of digital libraries, it's now easier than ever to manage your book collection. In this article, we'll explore the process of adding a new book to your library, from creating a POST endpoint to implementing unit and integration tests.

Description

Implementing a feature that allows users to add a new book to their library is a crucial aspect of any digital library. This feature should enable users to enter book details such as title, author, genre, and publication date. In this section, we'll delve into the requirements for this feature and outline the steps involved in implementing it.

Acceptance Criteria

To ensure that the "Add book" feature is implemented correctly, we need to define the acceptance criteria. The following criteria must be met:

Create a POST endpoint "/api/books" to add a new book to the backend: This endpoint should accept book data in a specific format and create a new book entry in the database.
The Route "/books/add" should display the form, for the user to add a book: This route should render a form that allows users to input book details.
Ensure that the added book appears in the list of books: After adding a new book, it should be displayed in the list of books, along with other existing books.

Tasks for Developers

To implement the "Add book" feature, the following tasks need to be completed:

Create a "Add book" button in the UI: This button should be visible on the book list page and should trigger the form to appear.
Implement a form to input book details: The form should include fields for title, author, genre, and publication date.
Create a POST request to send book data to the backend: This request should be sent when the user submits the form.
Implement Unit and Integration Tests: These tests should ensure that the "Add book" feature is working correctly and that the data is being stored in the database correctly.
Add some styling: The form and button should be styled to match the rest of the application.

Implementing the POST Endpoint

To create the POST endpoint, we'll use a programming language such as Python or JavaScript. We'll define a function that accepts book data in a specific format and creates a new book entry in the database.

Example Python Code

from flask import Flask, request, jsonify
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///books.db"
db = SQLAlchemy(app)

class Book(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    author = db.Column(db.String(100), nullable=False)
    genre = db.Column(db.String(100), nullable=False)
    publication_date = db.Column(db.Date, nullable=False)

@app.route("/api/books", methods=["POST"])
def add_book():
    data = request.get_json()
    book = Book(title=data["title"], author=data["author"], genre=data["genre"], publication_date=data["publication_date"])
    db.session.add(book)
    db.session.commit()
    return jsonify({"message": "Book added successfully"}), 201

Implementing the Form

To implement the form, we'll use a templating engine such as Jinja2. We'll define a template that includes fields for title, author, genre, and publication date.

Example Jinja2 Template

<form action="/books/add" method="post">
    <label for="title">Title:</label>
    <input type="text" id="title" name="title"><br><br>
    <label for="author">Author:</label>
    <input type="text" id="author" name="author"><br><br>
    <label for="genre">Genre:</label>
    <input type="text" id="genre" name="genre"><br><br>
    <label for="publication_date">Publication Date:</label>
    <input type="date" id="publication_date" name="publication_date"><br><br>
    <input type="submit" value="Add Book">
</form>
