python - SQLAlchemy group_by return object with aggregated values -

-

let's consider have such schema:

class owner(db.model):     __tablename__ = 'owners'      id = db.column(db.integer, nullable=false, primary_key=true, autoincrement=true)     name = db.column(db.unicode(30), nullable=false)      shares = db.relationship('share', secondary=lambda: shares_owners, lazy="dynamic")  class share(db.model):     __tablename__ = 'shares'      id = db.column(db.integer, nullable=false, primary_key=true, autoincrement=true)     apartment = db.column(db.integer, nullable=false)     value = db.column(db.integer, nullable=false)      owners = db.relationship('owner', secondary=lambda: shares_owners, lazy="dynamic")  shares_owners = db.table('shares_owners',     db.column('share_id', db.integer, db.foreignkey('shares.id')),     db.column('owner_id', db.integer, db.foreignkey('owners.id')) )

filtering shares owned owner piece of cake:

share.query.join(shares_owners, owner, user).filter(user.id == 1).all()

you can group , sum values func.sum when sqlalchemy returns summed field.

is there way force return share object (or based on share) summed value?

ideally call .summed() method instead of .one(), .first() or .all() return share object summed values.

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
