Debugging Bootstrap Modal Close Function in Rails 7.0.2.3

When developing a Rails application with Bootstrap 5.1, you may come across a common challenge: the need to keep your modals in sync with your application's state after forms are submitted. This is particularly crucial in scenarios where modal pop-ups are utilized for adding or editing items, such as tags. In this post, we’ll explore how to override the Bootstrap modal’s close function to ensure that your modal behaves as expected when data is changed and submitted.

The Problem

The issue arises in a Rails application where a Bootstrap modal is used to display a form for adding or modifying tags. Once a user submits the form, the modal does not close, which is beneficial for allowing multiple changes. However, after closing the modal, the displayed tag data on the page can become stale and may not reflect the updates made via the modal.

To address this, we want the modal's close function to either reload the page or better yet, trigger a turbo_stream.update to refresh the displayed tag list without needing a full page reload.

Implementing the Solution

Step 1: Update Your Modal’s JavaScript Controller

You'll need to adjust the Stimulus controller responsible for your modal to listen for the modal's hidden event. This event is triggered when the modal is about to be closed. We’ll implement code to either reload the page or send an update request to fetch the latest data dynamically.

Here is how the code might look:

In this example:

location.reload(); will simply refresh the page, ensuring all changes are visible.

If you comment out the reload function, you can further customize it to use Turbo to update the DOM with new data fetched from the server. You would set up a fetch request to get the content dynamically and then manipulate the DOM as needed.

Step 2: Ensure Your Modal Setup is Correct

Check your view where the modal is instantiated to confirm everything is set up properly. Here’s an example of how the modal might look in your Rails view code:

Step 3: Modify Your Turbo Logic For Updating Data

Consider what your application's turbo_stream.update would look like. You may have a Turbo stream action on your server-side code that provides the necessary updates upon submission. Make sure your controller logic is set to respond with the appropriate Turbo streams.

Conclusion

By making use of the Bootstrap modal's close event in conjunction with Turbo streams, you can effectively manage your modals in a way that keeps your application data in sync without excessive page reloads. Experiment with the options provided above to find the solution that best fits your needs! Happy coding!
