Django queryset filter problem

Using Django
1

Hi!

I need to write a queryset which filters 10 higher values and 10 lower values than a given value.

class Toy(models.Model):
    name = models.CharField()
    price = models.IntegerField()

With given price 56, I want to get a list of 10 toys whose prices are higher than the given value and most close to the given value and the same for the lower values.
Finally, I want to include the toy with given price as well.

I am not sure how I can filter this out.

Thanks in advance.

Hi!

Take a look at the 2 last examples of the cheatsheet with annotate, it might give you an idea.

Feel free to post any doubt.
