How to Add New Records in Django Instead of Updating Existing Ones

When working with Django, you may encounter a common problem: every time you attempt to add a new note, the application updates an existing record instead. This may leave you puzzled and frustrated, especially if you want to create a new record upon each submission. In this guide, we'll delve into the underlying cause of this issue and provide you with a straightforward solution to ensure every update generates a new activity note.

Understanding the Problem

In Django, creating objects in a database can be achieved through various methods. One common method is get_or_create(), which either retrieves an existing object or creates a new one if it doesn't exist. However, this isn't what we want when our goal is to create new records for every submission.

In your use case, you want to create a new Activity instance each time the user submits the form. Instead of updating the existing record, you need the form submission to lead to a completely new entry being created.

The Solution: Adjusting Your Code

To achieve the desired functionality, you can make some modifications in your view logic. Let's break it down step-by-step.

1. Modify the View Logic

Here is a revised version of your create_notes function that correctly handles form submissions:

2. Update Your HTML Template

You also need to ensure that your template correctly submits the form without including existing object data. Here is how your HTML form should look:

Key Changes Explained

Using create Instead of get_or_create: By removing get_or_create, you prevent overwriting existing records. Simply calling form.save() allows the framework to create a new record automatically.

Initial values in the Form: The form is initialized with the correct dealer instance each time, which supports the relational integrity of your database.

Error Handling: Added error messages for debugging to help catch any issues with form validation.

Conclusion

By following the steps above, you should now have a functioning Django view that creates a new activity record every time a user submits their notes. This evolution from updating existing records to generating new entries not only improves your application but also enhances the user experience significantly.
