[FIXED] How do I change the widget type of the DELETE field in a django formset

Issue

I'm using a formset with can_delete=True. I want to change the widget of the DELETE field to a hidden input. I can't seem to find a good way to do this. What I've tried is:

Change the form's widget to HiddenInput and/or add a hidden field in the form definition:

class MyForm(ModelForm):
    DELETE = forms.BooleanField(widget=forms.HiddenInput)

    class Meta:
        model = MyModel
        widgets = {'DELETE' : forms.HiddenInput}

Do the above with a change in the formset

class MyFormSet(BaseModelFormSet):

def add_fields(self, form, index):
    originalDeletion = None
    if DELETION_FIELD_NAME in form.fields:
        originalDeletion = form.fields[DELETION_FIELD_NAME]

    super(MyFormSet, self).add_fields(form,index)

    if originalDeletion is not None:
        form.fields[DELETION_FIELD_NAME] = originalDeletion

If I do these both it does actually change the field to hidden but this seems like a bit of a hack (effectively overwriting the usual add_fields method). How are you supposed to do this?

== EDIT ==

It turns out that using a hidden field is not so good with the form framework anyway. You should definitely use a checkbox and hide it with css. If you want to do adjust the css of the checkbox in Django I still think you have to change the add_fields method as above, which then allows you to change the widget's css.

Solution

It doesn't change anything if your input is of type=hidden, or if it is of type=checkbox and display: none.

IMHO the elegant way in CSS would look like this:

td.delete input { display: none; }

Or in JavaScript:

$('td.delete input[type=checkbox]').hide()

Or, in the admin:

django.jQuery('td.delete input[type=checkbox]').hide()

That seems like a better direction to take because:

1. It won't change your JavaScript code and
2. It's one line of code vs. so much Python hacks
