However, you may find that while you can save tags through the Django admin panel, you struggle to do so through your forms when a user submits them. Let's take a look at how to resolve this issue.

The Solution

We will walk you through the necessary adjustments to ensure you can save tags from user input effectively.

Step 1: Update Your Views

Save the Model Instance First: Before managing tags, ensure the publish instance is saved to the database.

Use form.save_m2m(): This function will take care of saving the many-to-many relationships such as tags automatically.

Step 2: Ensure the Form Handles Tags

Make sure your form is set up correctly to manage tags. In the DisplayformNew class, you can define how tags will be processed. Your existing form is good, but ensure it includes the tags field correctly:
