API for storing and retrieving Atom entries.
Project description
This module defines a simple API for storing and retrieving Atom entries in different storage backends. Entries are defined using a JSON-like syntax:
>>> import datetime >>> entry = {'id' : 'http://example.com/1', ... 'title' : 'My first entry', ... 'updated': datetime.datetime.utcnow(), ... }
The module comes with a shelve backend:
>>> from atomstorage import EntryManager >>> em = EntryManager('shelve://file.db') >>> em.create_entry(entry) {'updated': datetime.datetime(2006, 8, 15, 16, 27, 7, 960677), 'id': 'http://example.com/1', 'title': 'My first entry'}
New backends can be easily added by creating a module and setting an atomstorage.backend entry point. A SQLite backend is currently being developed.
The API defines a few methods the entry manager should have. To retrieve all entries, sorted by time (last to first):
>>> entries = em.get_entries()
The last 10 entries:
>>> entries = em.get_entries(10)
Retrieve the entry with id “1”:
>>> entry = em.get_entry("1")
Delete the same entry:
>>> em.delete_entry("1")
Get all entries from August 2006:
>>> entries = em.get_entries_by_date(2006, 8)
Or from the “tech” category:
>>> entries = em.get_entries_by_category("tech")
To search for entries mentioning “Python”:
>>> entries = em.search("Python")
The API is by no means final. Comments, suggestions, patches and critics are welcome.
