Modify SQL queries to use different field for lookup

django-models-hashlookup

Modify SQL queries to use different field for lookup.

Queries like:

  Model.objects.filter(field_name__field='big_text')

will be translated to:

  Model.objects.filter(field_name__field_hash='dsfsdfergt345rfjspofj')

so if you have index on field_hash, queries will become more faster

Example

1 Model

  from django.db import models
  from hashlookups.managers import ManagerHash
  
  class GoodsModel(models.Model):
    good_name = models.TextField(null=True)
    good_name_hash = models.CharField(max_length=100, unique=True)

    objects = ManagerHash()

2 Code

  GoodsModel.objects.filter(good_name='my super special good')

3 Result sql

  SELECT * FROM goodsmodel WHERE good_name_hash = '5974e28ba61e8a9dfaba28236f0ad01bfa3bbe6ce552f0b0705492f94bbc1164'
