How to Create a Slug in Django: A Step-by-Step Guide

Are you struggling with creating a slug in Django and not getting the results you expected? Don't worry, we've got you covered! In this blog post, we'll walk you through the process of creating a slug and show you some common pitfalls along the way. Let's dive in! 💪🐍

Understanding the Problem

The issue at hand is that when you save a model object with a SlugField in Django, the value is not automatically converted into a slug format. Instead, it retains the original string value. 🤔

The Code

Here's an example of a simple model with a SlugField:

from django.db import models

class Test(models.Model):
    q = models.CharField(max_length=30)
    s = models.SlugField()

When you save an instance of this model and check the value of the s field, you might be surprised to find that it hasn't been converted into a slug as expected. Let's see why that happens.

The Issue at Play

When you assign a value to the SlugField, Django doesn't automatically convert spaces into dashes or apply any other slug formatting. It treats the value as any other string. This behavior can lead to unexpected results and is a common stumbling block for many Django beginners. 😱

The Solution

To convert the value into a slug format, you need to use Django's built-in function called slugify(). This function takes care of replacing spaces with dashes, removing special characters, and making the text lowercase. Here's how you can use it:

from django.utils.text import slugify

t = Test(q="aa a a a", s=slugify("b b b b"))
t.save()

By passing the value through the slugify() function before saving, you can ensure that the SlugField is populated with a correctly formatted slug. 👍

Testing the Solution

After applying the solution, let's verify if the value of s has been converted into a slug:

>>> t.s
'b-b-b-b'

Hooray! The value has been successfully converted into a slug format. 😄

Conclusion

Creating a slug in Django is a straightforward process once you understand how to use the slugify() function. By applying this simple solution, you can ensure that your slugs are properly formatted and consistent throughout your application.
