Hello,
i'm writing web-based photo gallery using pylons have the following
question:
Each photo in gallery have one row in 'photos' table and files on disk
(original file and preview).
I have Photo class, mapped to photos table:
class Photo(Base):
__tablename__ = "photos"
id = Column(Integer, primary_key=True)
name = Column(Unicode(256)) # relative path to image on the
filesystem
display_name = Column(Unicode(256))
album_id = Column(Integer, ForeignKey('albums.id'))
created = Column(DateTime)
width = Column(Integer)
height = Column(Integer)
hidden = Column(Boolean)
I want to put all code for creating and destroying photos to model.
So I've to add constructor, for example
def __init__(self, path_to_file, display_name, album_id):
self.display_name = display_name
self.album_id = album_id
# analyze file, create preview and fill remaining fields
It seems to be working, but should I call Base constructor ? And which
argument must be given to it ?
The second question is how can i implement destructor, which will be
called, when i issue session.delete(photo) ? __del__ will not work,
because it called each time the object is destroyed by garbage
collector.
