Are you looking for a way to customize your Django edit form but aren’t quite sure where to start? Look no further! With these simple steps, you’ll be able to customize your Django edit form to fit your exact needs.
First and foremost, it’s important to understand the difference between the Django add form and edit form. While the add form is used to create a new record in a database, the edit form is used to modify an existing record. This means that if you want to make changes to your edit form, you will need to dig a little deeper.
Luckily, customizing your Django edit form can be done by creating a new django form class that inherits from the original model form class. In this new form class, you can specify exactly which fields you want to include or exclude, set custom help text, and even add new validations.
Finally, don’t forget about the power of Django’s template system when customizing your edit form. By modifying the template that renders your form, you can change the look and feel, add custom buttons or links, and even embed a custom save button that triggers additional actions upon submission.
So what are you waiting for? With these tips and tricks, you’ll be well on your way to customizing your Django edit form to suit your exact needs.

Introduction
Django is a high-level Python web framework that facilitates rapid development, clean and pragmatic design. One of the most significant advantages of Django is its powerful admin interface, which allows you to manage your application’s data in a simple and intuitive way. While developing a Django application, you may need to customize the edit form to provide the best possible user experience. In this article, we will be discussing how to customize Django edit form from add form.
Difference between Django Add and Edit Forms
Before we dive into customizing Django’s edit form, let’s understand the difference between Django’s add and edit forms.
Add Form
The add form is responsible for creating a new instance of the model. It contains fields that accept data inputs to create a new record in the database.
Edit Form
On the other hand, the edit form is responsible for updating the existing instance of the model. It provides pre-filled fields with data retrieved from the specific record in the database.
Customizing Django Edit Form
Once we understand the difference between Django’s add and edit forms, it’s time to move towards customizing the edit form.
Step 1: Create a Django Model Form
The first step in customizing the Django edit form is to create a Django model form. If we don’t want to change the existing form fields, we can use the model form to extend the default behavior. The model form is simply a class that inherits from Django’s built-in ModelForm class.
Step 2: Override the default init method of the model form
The next step is to override the default init method of the model form. In this method, we can access the form fields and customize them as per our requirements. This method is called when the edit form is initialized.
Step 3: Override the default save method of the model form
In the third step, we override the default save method of the model form. This method is called when the form data is submitted. Here, we can access the cleaned data and update the instance attributes accordingly.
Step 4: Create a new view to render the customized edit form
The final step is to create a new view that renders the customized edit form. We can create a new URL pattern and view function that maps to this view.
Comparison Table
Let’s summarise the differences between the default Django edit form and a customized edit form in the following table.
| Default Django Edit Form | Customized Django Edit Form |
|---|---|
| The default edit form provides pre-filled form fields as per the record from the database. | A customized edit form can provide additional form fields or remove existing ones as per the needs. |
| The default edit form does not provide any custom widgets or validation. | A customized edit form can have custom validation and custom widgets to enhance the user experience. |
| The default edit form relies on the model attributes for validation and pre-filling of fields. | A customized edit form can also use custom methods and attributes to pre-fill the fields or validate the form data. |
Opinion
Customizing Django’s edit form can provide a better user experience to the application’s users. With a customized edit form, we can add custom validation, custom widgets, and customize the form fields as per our requirements. However, creating a customized edit form requires more effort than using the default edit form.
In conclusion, customizing the Django edit form can significantly enhance the application’s overall user experience, and if done thoughtfully, with good planning, can be an excellent way for developers to put their own touch on updating specific data structures within the site.
