[Fixed]-Django unbound and bound forms

You’ve redefined the signature of your form so that the first argument is hero, but then you instantiate it with just request.POST.

Instead of doing that, get hero from the kwargs, and always make sure you accept both args and kwargs.

def __init__(self, *args, **kwargs):
    hero = kwargs.pop('hero', None)
    super(DeckForm, self).__init__(*args, **kwargs)
    if hero:
        ...

Remember to pass the hero argument in by keyword:

return render(request, 'hsguides/guide_create.html', {
    'DeckForm': DeckForm(hero=hero),
    'GuideForm': GuideForm,
})
