filedepot 0.11.0

standalone

Here is a simple example of using depot standalone to store files on MongoDB:

from depot.manager import DepotManager

# Configure a *default* depot to store files on MongoDB GridFS
DepotManager.configure('default', {
    'depot.backend': 'depot.io.gridfs.GridFSStorage',
    'depot.mongouri': 'mongodb://localhost/db'
})

depot = DepotManager.get()

# Save the file and get the fileid
fileid = depot.create(open('/tmp/file.png'))

# Get the file back
stored_file = depot.get(fileid)
print stored_file.filename
print stored_file.content_type

models

Or you can use depot with SQLAlchemy to store attachments:

from depot.fields.sqlalchemy import UploadedFileField
from depot.fields.specialized.image import UploadedImageWithThumb


class Document(Base):
    __tablename__ = 'document'

    uid = Column(Integer, autoincrement=True, primary_key=True)
    name = Column(Unicode(16), unique=True)
    content = Column('content_col', UploadedFileField)  # plain attached file

    # photo field will automatically generate thumbnail
    photo = Column(UploadedFileField(upload_type=UploadedImageWithThumb))


# Store documents with attached files, the source can be a file or bytes
doc = Document(name=u'Foo',
            content=b'TEXT CONTENT STORED AS FILE',
            photo=open('/tmp/file.png'))
DBSession.add(doc)
DBSession.flush()

# DEPOT is session aware, commit/rollback to keep or delete the stored files.
DBSession.commit()
