Hi all,
I'm trying to configure these two classes so the song class returns the
contents of the file dictionary as well but am having issues figuring this
out.
Here is what I have so far. If you have any suggestions on how I can get
Song.as_dictionary to return something like this:
> {
>
> "id": 1,
>
> "file": {
>
> "id": 7,
>
> "name": "Shady_Grove.mp3"
>
> }
>
> }
>
>
This is what I have so far
> class Song(Base):
>
> """ The Song model:
>
> This should have an integer id column,
>
> a column specifying a one-to-one relationship with a File. """
>
> __tablename__ = "songs"
>
> id = Column(Integer, Sequence('song_id_sequence'), primary_key=True)
>
> info = relationship("File", uselist=False, backref="songs")
>
>
>> def as_dictionary(self):
>
> song = {
>
> "id": self.id,
>
> "info": self.info }
>
> # need to add file info in here
>
> return song
>
>
>> class File(Base):
>
> """ The File model: This should have an integer id column
>
> a string column for the file name
>
> and the backref from the one-to-one relationship with the Song."""
>
> __tablename__ = "files"
>
> id = Column(Integer, Sequence('file_id_sequence'), primary_key=True)
>
> name = String(1024)
>
> song_id = Column(Integer, ForeignKey('songs.id'))
>
>
>> def as_dictionary(self):
>
> file = {
>
> "id": self.id,
>
> "name": self.name }
>
> return file
>
