python - Django input as hour and minutes, saved as minutes -


in django webapp, i'm creating form user inputs time taken complete activity in hours , minutes (eg. 2 hours, 33 minutes).

i want input appear client side hours , minutes, save model minutes (eg. 153)

currently, input given in minutes. worry ugly/unreadable:

models.py: 

class activity(models.model):      time_taken = models.positiveintegerfield(default=0)

add_activity.html:

<form id="add_session_form" method="post" action="" enctype="multipart/form-data">      {% csrf_token %}      {{ add_activity_form.as_p }}      <input type="submit" name="submit" value="add activity" />   </form>

forms.py:

class activity(forms.modelform):            class meta:          model = activity          fields = ('time_taken', 'subject')

could please assist me in altering form's input users individually enter hours , minutes, whilst storing time in minutes.

in form

class activityform(forms.modelform):     hours = forms.integerfield(max_value=12,min_value=0)     class meta:         model = activity         fields = ('time_taken', 'subject')

render forms doing

in view 

form = activityform(request.post) hours = form.cleaned_data['hours'] minutes = form.cleaned_data['time_taken']  total_time = 60*hours + minutes activity.objects.create(time_taken = total_time)
