QuerySet API Batch method

Query method batch is handy for minimizing the number of queries that need to be made in certain situations. However it is only usual for pre-selecting ForeignKey relations.

Example Usage

from batch_query import BatchManager

class Section(models.Model):

name = models.CharField(max_length=32)

class Location(models.Model):

name = models.CharField(max_length=32)

class Entry(models.Model):

name = models.CharField(max_length=255) section = models.ForeignKey(Section, blank=True, null=True) location = models.ForeignKey(Location, blank=True, null=True)

objects = BatchManager()

>>> Entry.objects.batch("section") >>> Entry.objects.batch("section", "location") >>> Entry.objects.batch("section").batch("location") >>> Entry.objects.batch("section").batch("location").filter(section=section_1)
