Hi,
I'm using flask-sqlahcmey and I have a self referential relationship like
this:
class FileData(db.Model):
id = db.Column(db.Integer, primary_key = True)
primary_file_data_id = db.Column(db.Integer, ForeignKey('file_data.id'))
is_edited_file = db.Column(db.Boolean, default = False, nullable = False
)
edited_datas = db.relationship("FileData", remote_side =
[primary_file_data_id], primaryjoin="and_( FileData.id ==
FileData.primary_file_data_id , FileData.is_edited_file == True )")
The intent of the edited_datas is to find the the records where the
primary_file_data_id equals the current FileData instance id and where the
is_edited_file flag is true. The relationship seems to be functioning
correctly, but I'm getting a warning from sqlalchemy:
/Users/Victor/Documents/Python/proj/pgp_venv/lib/python2.7/site-packages/sqlalchemy/orm/relationships.py:2085:
SAWarning: Non-simple column elements in primary join condition for
property FileData.edited_files - consider using remote() annotations to
mark the remote side.
self._warn_non_column_elements()
I think I am using the remote_side keyword properly. Should I be using
something else to mark the remote side?
If I'm doing everything correclty, is there a way to suppress this (and
only this) message? I would rather get this message than miss other
warning SA might give me.
Thank you for your help,
~Victor
