Managing Multiple Forms with a Single Create View in Django

In web development, particularly when using Django, you might find yourself wanting to submit multiple forms simultaneously. However, the CreateView class typically only accepts one form at a time, leading to complications when managing several related forms. In this guide, we will tackle the challenge of creating a single view for multiple forms in Django, specifically when they are interconnected through foreign key relationships.

Understanding the Problem

When you have multiple forms, such as:

MyForm

EducationForm

ExperienceForm

RecommendationForm

OtherDocumentsForm

You may want to display all of them in one template and submit them in a single request. This situation often arises when forms are related to a primary model—such as MyForm, which is linked to the other forms via foreign keys.

However, since CreateView only accepts one form class, how do you effectively utilize it for this scenario? Let's break down the solution.

Solution Overview

To create a solution for managing multiple forms in a single view without losing connection between them, follow these steps:

Exclude ForeignKey Fields from Forms

Create a Custom View for Processing Forms

Render All Forms in One Template

Step 1: Exclude ForeignKey Fields from Forms

To ensure that each related form can be handled properly, you need to exclude the foreign key referencing UserForm_uz from the EducationForm, ExperienceForm, RecommendationForm, and OtherDocumentsForm. Here's how to do that:

This step must be repeated for each of the forms that reference MyForm.

Step 2: Create a Custom View for Processing Forms

Next, you’ll need to define a view that can handle the submission of all these forms. This view should:

Initialize each form.

Validate them all together.

Save MyForm first and then use the output to link it as a foreign key to the other forms.

Step 3: Render All Forms in One Template

Finally, to make sure that all forms are presented correctly, you'll need to render them in the same template within one HTML form tag. Below is a simple code snippet for the template:

Conclusion

By following these steps, you can effectively manage multiple forms within a single view in Django. This not only streamlines the submission process but also maintains the necessary relationships between your models through foreign keys.

Handling multiple forms this way can help make your application more user-friendly and efficient, eliminating the need for users to fill out several forms separately.
