Desarrollando Aplicaciones con Ubuntu One Les Habla: Roberto Alsina Cualquier
cosa, interrumpan, no hay problema. 1
Qué es Ubuntu One • Servicio de storage online •
File sync • Music Store / Music Streaming • U1DB 2
Sync Client 3
APIs • Accounts • Files API • Music Streaming •
U1DB 4
Accounts • Ubuntu Desktop • Websites • Windows • Hagalo
usted mismo 5
Autorización en Ubuntu Usando ubuntuone.platform.credentials: @defer.inlineCallbacks def get_credentials(): tool =
CredentialsManagementTool() creds = yield tool.register() oauth_consumer = oauth2.Consumer( creds['consumer_key'], creds['consumer_secret']) oauth_token = oauth2.Token( creds['token'], creds['token_secret']) 6
Autorización en Django OAuth 1.0a. Usando django_oauth_client: @oauth_token_required('ubuntuone') def create_volume(request):
client = get_client(request.user, 'ubuntuone') response, content = client.request( 'https://one.ubuntu.com/api/file_storage/v1/volumes/~/Shoreham', 'PUT') return redirect('/accounts/profile/') 7
Hágalo Usted Mismo Bueno, es OAuth, fijáte. 8
Files • Volúmenes • Listar/Bajar/Subir/Borrar archivos • Publicar archivos •
Interacción con Sync 9
En Websites @oauth_token_required('ubuntuone') def create_volume(request): client = get_client(request.user, 'ubuntuone') response,
content = client.request( 'https://one.ubuntu.com/api/file_storage/v1/volumes/~/Shoreham', 'PUT') return redirect('/accounts/profile/') 10
En Ubuntu Es Via DBus: /folders method com.ubuntuone.SyncDaemon.Folders.create(path:s) 11
U1DB • Datos estructurados • Sincronizada • Distribuída • Online
y Offline 12
Plataformas • Ubuntu/Windows/OS X - Python - SQLite • Ubuntu
- Vala - SQLite • Ubuntu/Windows/OS X - C - SQLite • Web - javascript - localStorage • Android - Java - SQLite • iOS - Objective-C - SQLite 13
Documentos • create_doc • put_doc • revisiones • delete_doc •
get_doc / get_docs 14
Índices Es un poco más denso, vean el manual? OK!
15
Crear Índices {"firstname": "John", "surname", "Barnes", "position": "left wing"} ID
jb {"firstname": "Jan", "surname", "Molby", "position": "midfield"} ID jm {"firstname": "Alan", "surname", "Hansen", "position": "defence"} ID ah {"firstname": "John", "surname", "Wayne", "position": "filmstar"} ID jw create_index("by-firstname", ["firstname"]) 16
Usar el Índice get_from_index( "by-firstname", [("John", )]) Devuelve una lista
de IDs. 17
Más Ejemplos get_from_index("by_firstname", [("J*")]) get_from_index("by_firstname", [("Jan"), ("Alan")]) 18
Ejemplo import json, u1db db = u1db.open(":memory:", create=True) doc1 =
db.create_doc(json.dumps({"key": "value"}), doc_id="testdoc1") doc2 = db.create_doc(json.dumps({"key": "value"}), doc_id="testdoc2") for doc in db.get_docs(["testdoc2","testdoc1"]): print doc.doc_id Resultado: testdoc1 testdoc2 19
Syncing • API REST • Cliente / Servidor • Conflictos
20
Conflictos • Obtenés un ConflictedDoc • Pensás • Llamás a
resolve_doc 21
Imaginación 22
