i have a case like this : Models
class Car(models.Model):
description = models.CharField(max_length=200)
is_available = models.BooleanField(default=False)
class Rental(models.Model):
car = models.ManyToManyField(Car)
My question is, how to display Car on Rental models with is_available = True. On django admin ? Thank you
You can override get_queryset method of the django admin class.
Generic Syntax for that->
class MyModelAdmin(admin.ModelAdmin):
def get_queryset(self, request):
qs = super().get_queryset(request)
if request.user.is_superuser:
return qs
return qs.filter(author=request.user)
In your case this would be -:
class RentalAdmin(admin.ModelAdmin):
def get_queryset(self,request):
qs = super().get_queryset(request)
return qs.filter(car__is_available=True)
You can Refer to the docs here
For Inline your code should be -:
class CarInline(admin.StackedInline):
model=Rental.car.through
#model=Car
def get_queryset(self,request):
qs = super().get_queryset(request)
return qs.filter(is_available=True)
class RentalAdmin(admin.ModelAdmin):
inlines=[CarInline]
