Dead submit / update / delete buttons, nothing happens on click.

[omarcoming]

When I fill out a new form and click the submit button, nothing happens. I've pored over the documentation and followed the examples but no luck. Django(5.0.2) and django-formset(1.3.8) have been updated. The only changes I saw that applied were changing 'click' to 'df-click' in my customer-add.html template but that still didn't fix the problem.

I have a few ideas what could be causing the problem and corresponding questions but am unsure how to test them out as I this is the first time I'm working with css / bootstrap / javascript / typescript (I only have a small background in Python).

1. Does it matter whether you load scripts in the base template or child template?
2. Do the order of scripts matter and does it matter where in the head we're loading scripts relative to other elements?
3. Do I have to move the static files from the formset library to my static folder in my project?

I posted this in discussion instead of issues because I doubt the issue is a problem with the formset library as this is a very basic function and I'm sure other people would have run into it if it were. A fresh set of eyes on this would be greatly appreciated because I am stuck! I get the feeling this is something very simple I'm overlooking.

class Customer(models.Model):
    first_name = models.CharField('First Name', max_length=55, blank=True)

    phone = models.CharField('Phone Number', max_length=10, blank=True)
    alt_phone = models.CharField('Alt Phone Number', max_length=10, blank=True)
    company = models.CharField('Company', max_length=55, blank=True)

The only changes I saw that applied were changing 'click' to 'df-click' in my customer-add.html template but that still didn't fix the problem.

This change has been introduced in version 1 to avoid naming conflicts with other libraries.

Does it matter whether you load scripts in the base template or child template?

No.

Do the order of scripts matter and does it matter where in the head we're loading scripts relative to other elements?

This might be a problem, but is unlikely.

Do I have to move the static files from the formset library to my static folder in my project?

No. If formset has been added to INSTALLED_APPS Django will handle that for you.

Anyway, first question to answer is: Is the submitted data send to the server? Or in other words, is the problem part of the client-side or on the server-side. Did you open the browser's devtools and checked for errors there?

[jrief]

Incorrect use of "label for=FORM_ELEMENT"

This error does not emerge from django-formset. It looks like it's from the browser itself.

In your browser console, how does the response body looks like.

Unfortunately there are some issues with hidden required fields. If they are not handled correctly by the clean()-method, they never show up, and the form never complains visually.

In your browser console, how does the response body looks like.

The console tab doesn't show any output. The response body in the network tab only shows the GET request. Nothing happens in the console when I click 'add'

Unfortunately there are some issues with hidden required fields. If they are not handled correctly by the clean()-method, they never show up, and the form never complains visually.

I created a new project to try to isolate the issue and the model I'm using does have a hidden field (although it was not required) but removing it didn't change anything.

[jrief]

May I have a look at the code? Just create a small project with one view using your form collection and share it in GitHub.

[omarcoming]

Absolutely! Here's the link And thank you so much for your help, I tried a few different approaches before coming across django-formset and it's functionality is exactly what I need!

[omarcoming]

I just realized I didn't include the requirements.txt file so it has been updated.
