Django forms, how to dynamically add fields?

Question

Django

class MyForm(forms.Form):
    slug = forms.CharField(max_length=50)

There is a form, you need to dynamically add an unknown number of fields of the same type to it in advance.
I can’t figure out how to turn something like that, can someone kick in the right direction?
This came to my mind, but I don’t know how true it is, pseudocode.

class MyForm(forms.Form):
    def __init__(self, *args):
         super(MyForm, self).__init__(*args)
         self.fields.update({'fields': forms.CharField(max_length=50),})
    slug = forms.CharField(max_length=50)

Answer 1

class MyForm(forms.Form):
    def __init__(self, *args, **kwargs):
        slugs_cnt = kwargs.pop('slugs_cnt', None)
        super(MyForm, self).__init__(*args, **kwargs)

        if slugs_cnt:
            for i in xrange(1, slugs_cnt + 1):
                self.fields['slug_{}'.format(i)] = forms.CharField(max_length=50)

Answer 2

Formset.

Answer 3

Try this, create a form class as you go:

MyForm = type('MyForm', (forms.Form,), {
    'slug01': forms.CharField(max_length=50),
    'slug02': forms.CharField(max_length=50),
    'slug03': forms.CharField(max_length=50),
})
form = MyForm()
...

Poidee should work.
