kinto-client 1.0.0

Usage

• The first version of this API doesn’t cache any access nor provide any refresh mechanism. If you want to be sure you have the latest data available, issue another call.

Here is an overview of what the API provides:

from kinto_client import Client

client = Client(server_url="http://localhost:8888/v1",
                auth=('alexis', 'p4ssw0rd'))

records = client.get_records(bucket='default', collection='todos')
for i, record in enumerate(records['data']):
    record['title'] = 'Todo #%d' %i

for record in records:
    client.update_record(record)

Creating a client

The passed auth parameter is a requests authentication policy, allowing authenticating using whatever scheme fits you best.

By default, Kinto supports Firefox Accounts and Basic authentication policies.

from kinto_client import Client
credentials = ('alexis', 'p4ssw0rd')

client = Client(server_url='http://localhost:8888/v1',
                auth=credentials)

It is also possible to pass the bucket and the collection to the client at creation time, so that this value will be used by default.

client = Client(bucket="payments", collection="receipts", auth=auth)

Handling buckets

All operations are rooted in a bucket. It makes little sense for one application to handle multiple buckets at once (but it is possible). If no specific bucket name is provided, the “default” bucket is used.

from kinto_client import Client
credentials = ('alexis', 'p4ssw0rd')

client = Client(server_url='http://localhost:8888/v1',
                auth=credentials)
client.create_bucket('payments')
client.get_bucket('payments')

# It is also possible to manipulate bucket permissions (see later)
client.update_bucket('payments', permissions={})

Collections

A collection is where records are stored.

client.create_collection('receipts', bucket='payments')

# Or get an existing one.
client.get_collection('receipts', bucket='payments')

# To delete an existing collection.
client.delete_collection('receipts', bucket='payments')

Records

Records can be retrieved from and saved to collections.

A record is a dict with the “permissions” and “data” keys.

# You can pass a python dictionary to create the record
# bucket='default' can be omitted since it's the default value

client.create_record(data={'id': 1234, status: 'done', title: 'Todo #1'},
                     collection='todos', bucket='default')

# Retrieve all records.
record = client.get_records(collection='todos', bucket='default')

# Retrieve a specific record and update it.
record = client.get_record('89881454-e4e9-4ef0-99a9-404d95900352',
                           collection='todos', bucket='default')
client.update_record(record, collection='todos', bucket='default')

# Update multiple records at once.
client.update_records(records, collection='todos')

# It is also possible to delete records.
client.delete_record(id='89881454-e4e9-4ef0-99a9-404d95900352',
                     collection='todos')

Permissions

By default, authors will get read and write access to the manipulated objects. It is possible to change this behavior by passing a dict to the permissions parameter.

client.create_record(
    data={'foo': 'bar'},
    permissions={'read': ['group:groupid']},
    collection='todos')

Buckets, collections and records have permissions which can be edited. For instance to give access to “leplatrem” to a specific record, you would do:

record = client.get_record(1234, collection='todos', bucket='alexis')
record['permissions']['write'].append('leplatrem')
client.update_record(record)

# During creation, it is possible to pass the permissions dict.
client.create_record(data={'foo': 'bar'}, permissions={})
