When you explicitly write list in choices it evaluates at module
import type. To avoid this write function and pass it as 'choices'
parameter
def get_choices():
[(d.id,d.name) for d in Deck.objects.all()]
#...
deck = forms.ChoiceField(required=True,choices = get_choices )
When this function will be called every time the form is rendered
