Defining tasks in Django - Mini Project: Build & Apply

Defining Tasks in Django

📖 Scenario: You are building a Django project that needs to perform background tasks. To do this, you will define a simple task function that can be called later by a task runner.

🎯 Goal: Create a Django task function named send_reminder_email that accepts a user_email parameter and prints a message simulating sending an email.

📋 What You'll Learn

Create a Python function named send_reminder_email in a file called tasks.py inside a Django app.

The function must accept one parameter called user_email.

Inside the function, write a print statement that outputs exactly: Sending reminder email to {user_email} using an f-string.

Ensure the function is properly defined with def syntax.

💡 Why This Matters

Knowing how to define and use tasks in Django is essential for backend developers working on scalable and responsive web applications.

1

Create the tasks.py file and define the function

Create a file named tasks.py inside your Django app folder. Inside it, define a function called send_reminder_email that takes one parameter named user_email.

Django

# Define the function send_reminder_email with parameter user_email
# Your code here

Use the def keyword to define the function with the exact name and parameter.

2

Add a print statement inside the function

Inside the send_reminder_email function, add a print statement that outputs Sending reminder email to {user_email} using an f-string exactly as shown.

Django

def send_reminder_email(user_email):
    # Add print statement here
    # Your code here

Need a hint?

Use print(f"Sending reminder email to {user_email}") inside the function body.

3

Import the task function in views.py

In your Django app's views.py file, import the send_reminder_email function from the tasks module.

Django

def send_reminder_email(user_email):
    print(f"Sending reminder email to {user_email}")

# Import send_reminder_email in views.py
# Your code here

Need a hint?

Use from .tasks import send_reminder_email to import the function.

4

Call the task function in a view

Inside a Django view function named reminder_view in views.py, call the send_reminder_email function with the argument "[e-mail]".

Django

def send_reminder_email(user_email):
    print(f"Sending reminder email to {user_email}")

from .tasks import send_reminder_email

# Define reminder_view and call send_reminder_email
# Your code here

Need a hint?

Define reminder_view with request parameter and call send_reminder_email("[e-mail]") inside it.
