You are not sending CaptchaTestForm
to user when user makes a get request.
To do that, import CaptchaTestForm
in your view.
from .forms import CaptchaTestForm
Replace last line of your view with this to send that form.
form = CaptchaTestForm()
return render_to_response('signups.html', {'produtos':od,'promocoes':promocoes,
'slider':slider, 'form': CaptchaTestForm},
context_instance=RequestContext(request))
