How to Use Slug Instead of ID in Vue.js for Django Projects

In the realm of web development, implementing user-friendly URLs can significantly enhance user experience and improve the search engine optimization (SEO) of your application. In this guide, we'll address a common challenge faced by developers using Django and Vue.js: how to access model details using a slug instead of an ID.

Understanding the Problem

If you have been working with a Django + Vue.js application and want to retrieve data using slugs, rather than numerical IDs, you might have encountered a 404 error when trying to access paths like http://localhost:8080/magazines/<slug-magazine>. This issue often arises when the back-end API is not configured correctly to recognize slugs as identifiers for fetching data.

Example Scenario

In our example, we have a Magazine model that contains fields like title, description, and slug. The challenge is to properly configure the backend and frontend to retrieve information through slugs rather than default ID references.

Solution Overview

We will solve this problem in two main parts:

Configuration of the Django Backend to utilize slugs as the lookup field.

Modifications in the Vue.js Frontend to ensure smooth data retrieval.

1. Configuring the Django Backend

To successfully implement slug-based retrieval, you will make changes to your views.py and serializers.py files.

Update views.py

In your views.py, modify the MagazineViewSet to set the lookup_field to slug. This allows the viewset to use the slug for identifying records.

Update serializers.py

While updating your serializer, ensure that you specify the slug as the lookup field. This will ensure that it correctly handles requests that use slugs.

2. Modifying the Vue.js Frontend

Next, we need to ensure that our Vue.js application is set up to handle slugs in the routing as well as fetching data.

Update router/index.js

Check your router configuration to ensure it uses the slug in the route definition.

Update the Magazine.vue Component

In your Magazine.vue file, you will maintain the logic for fetching the Magazine details using the slug passed via the URL.

Conclusion

By following these steps, you can successfully set up your Django application to use slugs for retrieving resources, thereby creating more SEO-friendly URLs. When you navigate to http://localhost:8080/magazines/<slug-magazine>, your application should properly display the magazine details.

Implementing slugs over numeric IDs not only improves user experience but also enhances the visibility of your content on search engines.
