contract entity:
from api.extensions import db
from sqlalchemy.sql import expression
contracts_users = db.Table("contracts_users",
db.Column("contract_id"
, db.Integer, db.ForeignKey(
"contracts.id"), primary_key=True),
What is the code for PermissionEntity, ContractEntity, and the joining
table?
it will look like this

Perfect. That's exactly what I ended up doing. I added events
(after_insert/update/delete) for each backref.
For each has-many relationship (through a secondary table) I had to
consider the fact that the parent model would exist in session.dirty but
not trigger the "onupdate" action on the
This is my function but it does not do anything at the moment :
def delete_permission_by_contract_id(contract_id, permission_id):
# noqa: E501
"""Deletes permissions by contract ID
Returns all permissions related to a specific contract. # noqa: E501
:param contract_id: ID of

Thanks for the response...
I have one table for permissions which has 'PermissionEntity' and another

which is shown below:
[image:
`.get()` returns the corresponding row/object based on the primary key
https://docs.sqlalchemy.org/en/13/orm/query.html?highlight=get#sqlalchemy.orm.query.Query.get
assuming `PermissionEntity` has a primary key of (permission_id,
contact_id), the syntax from the examples would be:
some_object
[image: Capture.PNG]
permission_id and contract_id have a relationship in the database
How can i using remove a entry for example.. if permission_id = 2 and
contract_id = 2 exists in the same entry as shown on line one in database,
i want to be able to remove it from my database. (This entry
13 matches
