Simlutaneous deletion and creation not working

[pavlutom]

If I delete one item and create another in one POST, the new item is not created, only the deletion happens. It works fine if I remove line 95 in src/jquery.formset.js (totalForms.val(forms.length);). This code was introduced in #173. I'm not sure what was the purpose of this line, probably to fix some other error that I didn't notice.

I am using Django 3.0.7

I am seeing this as well with django 3.1

Thank god. I could not delete any formset form but the first one because of this line.
Hidden and therefore deleted rows still have to be enumerated in the management header's TOTAL_FORMS, as Django will only consider that amount for rows. Any rows surpassing this value will be disregarded. E.g. if you have two forms and you schedule one for deletion, TOTAL_FORMS updates to 1, which will then in turn result in the second form to be ignored by Django completely.

Reviewing #173, it seems like the author did not implement the library properly into his project, as decrementing beyond the specified amount of min_num is not possible. It is to note that this is mainly due to a sloppy documentation, as django-dynamic-formset not only requires formCssClass to be unique, but also addCssClass, deleteCssClass and possibly even deleteContainerClass. This may be due to an improperly setup selector in the library, but that's at least the current requirement/behavior.

I had the same problem, I spent hours looking for the problem and as you mention everything works fine for me if the line 95 src/jquery.formset.js (totalForms.val(forms.length);) is removed, I regard that code should be removed and another solution should be looked if it was introduced to fix some error.

I solved this problem without deleting the code. I assigned unique CSS class name to formCssClass for each formset as in Django Dynamic Formsets documentation:
$(".inline.{{ log_form.prefix }}").formset({
prefix: '{{ log_form.prefix }}',
formCssClass: 'dynamic-formset-{{ log_form.prefix }}'})`

Just here to add that indeed deleting (totalForms.val(forms.length);) from the code did the trick for me.

Thanks for this @pavlutom

I was having the same problem. Removing this line: totalForms.val(forms.length); solved the issue.

@karlos-perez, your solution probably has been working. but maybe you didn't understand what was the main issue. Not sure of course.
I'm just saying it because i was trying to solve using so many ways from Django tools, but i do realize that problem came from the JS file.
So, up to now. I do recommend use the solution which those guys have discovered.
Anyway thanks @karlos-perez
