Latest Version: 0.2.2

You can get detailed information about couchbase itself from and about its Python driver form

Quick Start

Less talk, more code. Set your authentication details first:

from couchbasekit import Connection

# you should do this somewhere beginning such as
Connection.auth('myusername', 'p@ssword')

Then define your model document.

import datetime
from couchbasekit import Document
from couchbasekit.fields import EmailField, ChoiceField
from example.samples.publisher import Publisher
from import Book

class Gender(ChoiceField):
    CHOICES = {
        'M': 'Male',
        'F': 'Female',

class Author(Document):
    __bucket_name__ = 'couchbasekit_samples'
    __key_field__ = 'slug' # optional
    doc_type = 'author'
    structure = {
        'slug': unicode,
        'first_name': unicode,
        'last_name': unicode,
        'gender': Gender,
        'email': EmailField,
        'publisher': Publisher, # kind of foreign key
        'books': [Book], # 1-to-many, or many-to-many? some-to-some.. :)
        'has_book': bool,
        'age': int,
        'created_at': datetime.datetime,
    default_values = { # optional
        'has_book': False,
        # don't worry about the timezone info!
        # it's auto assigned as to UTC, so all you have to do is:
        'created_at': datetime.datetime.utcnow,
    required_fields = ( # optional

Then use it as such;

>>> from import Author
>>> from couchbasekit.fields import EmailField
>>> douglas = Author()
>>> douglas.is_new_record
>>> try:
...     douglas.validate()
... except Author.StructureError as why:
...     print why
Key field "slug" is defined but not provided.
>>> douglas.slug = u'douglas_adams'
>>> try:
...     douglas.validate()
... except Author.StructureError as why:
...     print why
Required field for "first_name" is missing.
>>> isinstance(douglas, dict)
>>> douglas.update({
...     'first_name': u'Douglas',
...     'last_name': u'Adams',
...     'email': EmailField(''),
... })
>>> douglas.validate()
>>> douglas.cas_value # CAS value (version) of the couchbase document
>>> douglas.doc_id
>>> douglas.birthday is None
>>> douglas.non_exist_field
Traceback (most recent call last):

    return super(Document, self).__getattribute__(item)

>>> dna = Author('douglas_adams')
>>> dna.is_new_record
>>> douglas==dna
>>> douglas.has_book = True
>>> douglas==dna
>>> # nice!
