Requeriments

  • Django (>=1.1). It's possible that works with other versions lower 1.1

Installation

  • To use the "like/ilike lookup" with Django 1.4, 1.5 or 1.6 you need to install django_like (this app make a monkey patching) or to patch your Django.
  • To use the "like/ilike lookup" with Django 1.3, 1.2 or 1.1 you need to install django_like (this app make a monkey patching), You could patch your Django but I have not make a patch, but this will be very easy. You only have to see the monkey patch and to update the same, or you could see other patch and update more or less the same.
  • To use the "like/ilike lookup" with Django 1.7 you only need to install django_like but now this application does not make monkey patching. Now Django provide an API to do it.

In your settings.py

INSTALLED_APPS = (

    'django_like',

)
Or apply some of the next patches (This is not neccesary, you can only install the app):

Usage

Something that you can to do with like sentence

MyModel.objects.filter(field_name__like='xx%YY%zz')
MyModel.objects.filter(field_name__ilike='xx%yy%zz')
User.objects.filter(username__like='a%in')

It is more quick and more readable that something like this:

MyModel.objects.filter(field_name__regex='^xx.*YY.*zz$')

This app provider two new lookups: like and ilike.

Now you can compare the time it takes to run the same query, many times, with like and with regex

python manage.py benchmark_like

These are a results executing the benchmark_like in my machine:

Type & result \ Database postgres mysql sqllite oracle
like 0:00:50.727005 0:00:14.025656 0:01:36.089407 ?:??:??.??????

Example project

python manage.py syncdb --noinput
python manage.py loaddata app_data
python manage.py runserver
