Simple example:
#This prints valid key value
logging.info("Before AuthorArtist adding, author is: %s" %
video.author.key())
aa = AuthorArtists.get_or_insert("aa%s_%s" % (artist.name.lower
(),video.author.username.lower()),
artist = artist,
author = video.author)
#This gives error: ReferenceProperty failed to be resolved, because it
can't find author
logging.info("After AuthorArtist adding, AuthorArtist connection is:
%s" % aa.author.key())
Ok, let's look at our AuthorArtist object in Data Viewer. In author
field it have key
'ag9tdXNpY3ZpZGVvYnVnZXJyHAsSBkF1dGhvciIQYWRvbWlub3JlY29yZHMgCQw'. I
don't know what is it. db.get(this_ket) gives nothing. WTF?)
i have models:
class Author(db.Model):
name = db.StringProperty(required = True)
.....
class Video(db.Model):
videoid = db.StringProperty(required = True)
artist = db.ReferenceProperty(Artist, collection_name =
"videos")
author = db.ReferenceProperty(Author, collection_name =
"videos")
...
class Artist(db.Model):
name = db.StringProperty()
...
class AuthorArtists(db.Model):
author = db.ReferenceProperty(Author)
artist = db.ReferenceProperty(Artist)
