Full Documentation

Installation

To install nukedatastore, type:

$ pip install nukedatastore

Open Nuke's init.py file and add:

nuke.pluginAddPath('/path/to/your/local/python/site-packages')

Getting Started

To get started with nukedatastore, type in the Nuke Script Editor:

import nukedatastore

NukeDataStore

To initialise a NukeDataStore, type:

ds = nukedatastore.NukeDataStore('data_store')

To store data in the NukeDataStore, type:

ds['project_data'] = {'id': 1234, 'name': 'project name'}

To list all available keys in the NukeDataStore, type:

ds.list()
# ['project_data']

To retrieve stored data from the NukeDataStore, type:

ds['project_data']
# {'id': 1234, 'name': 'project name'}

A NukeDataStore can be frozen, to freeze, type:

ds.freeze()

Any further attempt to set data on the NukeDataStore will result in an error:

ds['color_data'] = {'id': 'AB-123', 'name': 'White'}
# nukedatastore.NukeDataStoreError: Cannot mutate frozen NukeDataStore

To un-freeze, type:

ds.unfreeze()

NukeAPICache

Working with the NukeAPICache is very similar. To register an API, type:

api_cache = nukedatastore.NukeAPICache('api_cache')
api.cache.register('project_data', 'https://project.your.domain.com')

To read the cached API data, type:

api_cache['project_data']

To update the API data, type:

api_cache.update('project_data')

To diff existing API data with new API data, type:

api_cache.diff('project_data')
# {'project_data': {'values_changed': {"root['headers']['X-Request-Id']": {'new_value': u'f5800c5e-4edb-4509-8339-4bcdf0b32732', 'old_value': u'd8ed6737-e5c8-49aa-b42e-58eb2ba472b9'}}}}
