sacrud

SACRUD will solve your problem of CRUD interface for SQLAlchemy. Originally created for pyramid_sacrud , but then in a separate project

Look how easy it is to use:

CREATE

from .models import DBSession, Groups
from sacrud.action import CRUD

data = {'name': 'Electronics',
        'parent_id': '10',}
group_obj = CRUD(DBSession, Groups).create(data)
print(group_obj.name)

If the entry already exists, just add the option update=True.

from .models import DBSession, Groups
from sacrud.action import CRUD

data = {'id': 6,  # existing entry
        'name': 'Electronics',
        'parent_id': '10',}
group_obj = CRUD(DBSession, Groups).create(data, update=True)
print(group_obj.name)

READ

from .models import DBSession, Groups
from sacrud.action import CRUD

group_obj = CRUD(DBSession, Groups).read()
print(group_obj.name)

UPDATE

from .models import DBSession, Groups
from sacrud.action import CRUD

group_obj = CRUD(DBSession, Groups).update(1, {'name': 'Chemistry'})
print(group_obj.name)

DELETE

from .models import DBSession, Groups
from sacrud.action import CRUD

CRUD(DBSession, Groups).delete(1)

M2M and M2O data

For adding multiple data for m2m or m2o use endinng [], ex.:

from .models import DBSession, Users
from sacrud.action import CRUD

CRUD(DBSession, Users).create(
    {'name': 'Vasya', 'sex': 1,
     'groups[]': ['["id", 1]', '["id", 2]']}
)

It support composit primary key.

Wraps your SQLAlchemy session

from sqlalchemy.orm import scoped_session, sessionmaker
from sacrud import CRUDSession

Session = scoped_session(sessionmaker(class_=CRUDSession))
DBSession = Session()
DBSession.sacrud(User).delete(1)

Wraps your zope.sqlalchemy session

from sqlalchemy.orm import scoped_session, sessionmaker
from zope.sqlalchemy import ZopeTransactionExtension
from sacrud import crud_sessionmaker

DBSession = crud_sessionmaker(scoped_session(
    sessionmaker(extension=ZopeTransactionExtension())))
DBSession.sacrud(User).delete(1)

Now CRUD available from DBSession.

group_obj = DBSession.sacrud(Groups).create(data)
print(group_obj.name)
