Render Django formset as array

Question

I have a model and i need to create form with multiple instances in it. To be more specific: i need to render my ModelForm inside regular form with square brackets next to it's fields names. Something like this in magicworld:

forms.py

class ManForm(ModelForm):
    class Meta:
        model = Man
        fields = ['name', 'age']

class PeopleForm(forms.Form):
    # modelless form
    people = ??? # array of ManForm instances or something

form.html

<form action="/people/create/">
    {{ form }}
</form>

output

<form action="/people/create/">
    <input type="text" name="name[0]"/>
    <input type="text" name="age[0]"/>
</form>

To tell you the truth, i don't know how to approach this problem at all. I tried modelformset_factory, but all i've got is <input type="text" name="form-0-name"/>

Can you explain why you think you need that specific format, rather than the one that Django formsets use? — Daniel Roseman

As discussed in the comments, you need a formset.

def create_people(request):
    PeopleFormSet = modelformset_factory(Man, form=ManForm)
    if request.method == 'POST':
        formset = PeopleFormSet(request.POST)
        if formset.is_valid():
            for form in formset:
                ... do something with individual form
    else:
        formset = PeopleFormSet()
    return render(request, template_name, {'formset': formset}

I didn't know that request.POST parses formsets that way. Thanks

For using formsets in function based views see @Daniel Roseman 's answer or read up here.

For class based views there is no built in generic view for this. According to this ticket they decided to let third-party-packages handle that. You can use django-extra-views for that.
