Hi. How to implement a form to update the quantity Car? I have no idea how
to do it. Thanks
Code: http://dpaste.com/808558/
or here:
class Car(models.Model):
name = models.CharField(max_length=50)
price = models.DecimalField()
class GarageCar(models.Model):
car = models.ForeignKey('Car')
garage = models.ForeignKey('Garage')
quantity = models.IntegerField()
class Garage(models.Model):
name = models.CharField("Garage_Name", max_length=30)
cars = models.ManyToManyField('Car', through='GarageCar',
blank=True, null=True)
owner = models.ForeignKey(User, related_name='owner_garage',
verbose_name='Owner Garage')
In this way updates the quantity:
In [2]: c = Car.objects.get(id=1) #here I need car ID
In [3]: g = Garage.objects.get(owner=1)
In [4]: q = 33 #here I need data from form
In [5]: c= GarageCar.objects.filter(car=c, garage=g).update(quantity=q)
views:
def show(request):
user = request.user
garage = Garage.objects.get(owner=user)
return render_to_response('garage.html', {'garage': garage,
'form':form})
in garage.html:
{% for item in garage.garagecar_set.all %}
Car: {{item.car.name}}
Price: {{item.car.price}}
Quantity: {{item.quantity}}
ID: {{item.car.id}}
{% endfor %}
in forms.py:
from django import forms
class QuantityForm(forms.Form):
q = forms.IntegerField
How to create ORM query to update quantity?
How to display a form field next to each car in template (with button
"Update")?
