Search for Django and PostgreSQL.

Requirements

  • Django >= 1.1
  • django-stringfield >= 0.1.5
  • django-cerial >= 0.0.2

Installation

First install the package from pypi using pip:

pip install django-pgindex

Then make pgindex an app in your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'pgindex',
    ...
)

Sync your database:

python manage.py syncdb

Done.

Usage

Create and Index class and register it to your model, much like registering an admin class to your model. Example:

# models.py
from django.db import models
from .index import ItemIndex
from pgindex import register

class Item(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

    def get_absolute_url(self):
        return '/item/'

register(Item, ItemIndex)


# index.py
from pgindex import IndexBase, Vector

class ItemIndex(IndexBase):
    def get_title(self):
        return self.obj.title

    def get_description(self):
        return self.obj.content

    def get_vectors(self):
        return (
            Vector(self.obj.title, weight='A'),
            Vector(self.obj.content, weight='B'),
        )

To search simply use the pgindex.search method which returns a queryset from the pgindex.models.Index model:

from pgindex import search

index_queryset = search('foo')

See tests for examples.

pgindex.IndexBase methods

get_title()

This should return the title of the indexed object.

get_description()

This should return the description of the indexed object.

get_url()

This should return the url of the indexed object.

get_data()

You can return additional data that will be stored in the index field here, this value will be pickled and depickled.

get_publish()

If this returns False and index will not be created

get_start_publish()

Can return a datetime.datetime which is the time when the index will be used. Returning None means that it will always be used.

get_end_publish()

Can return a datetime.datetime which is the time for the index expiration. Returning None means that it will never expire.

get_vectors()

This method needs to return a list or tuple of pgindex.Vector instances. This in turn is the base for the text search column.
