Adding a Phone Number Field to Django's UserCreationForm

When it comes to enhancing user interactions on your web application, collecting a user's phone number during the registration process can significantly improve communication. However, if you’ve ever tried to add a phone number field to Django's built-in UserCreationForm, you may have encountered some challenges. In this post, we will walk you through the process of successfully adding a PhoneNumberField to your registration form and avoid common pitfalls along the way.

The Problem

By default, Django’s UserCreationForm does not include a phone number field. If you try to add a phone number to it using the PhoneNumberField() directly within the form, like in the following code snippet, you might run into issues:

When you try to create migrations, you may receive an error regarding an "Unknown field(s)" for the User model. This is a common issue that arises because the User model does not natively include that field.

The Solution

To properly add a phone number field to your UserCreationForm, we suggest the following approach:

Step 1: Use a Character Field with Validators

Instead of using PhoneNumberField() directly, which is not a recognized field in the User model, you can use a CharField with a regex validator to ensure that the phone number format is correct.

Here’s how you can modify your form:

Step 2: Ensure the Model is Set Up Correctly

Since you also want to associate the phone number with the user model, ensure you have a separate model that includes the phone field. Here is an example of how your CustomerReg model might look:

With your model properly set up to store the phone numbers, you’ll be well on your way to improving your application's user experience!
