If I had time to respond yesterday, I would have said the same thing as
Simon.
Your database model leverages two separate parts of SQLAlchemy:
* SqlAlchemy ORM (Left side of the docs https://docs.sqlalchemy.org/en/13/ )
* SqlAlchemy Core (Right side of the docs https://docs.sqlalchemy.org/en/13/

example.. the whole first row as shown in the picture:

Hey Simon , permissions has only relationship with permission_contract and
contract only has relationship with permission_contract ...I want to be
able to delete the relationship from permission_contract ...
For example, in my permissions_contract, I may have permission_id = 1 which
is the id ta
It looks like you've got a many-to-many relationship between Contract and
Permission, and you want to remove a Permission from a Contract (or vice
versa). Is that right?
If so, you can do something like this:
contract =
permission =
contract.permissions.remove(permission)

Hey Jonathan, any luck? thanks

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

This is my function but it does not do anything at the moment :

Sorry, I meant the SqlAlchemy schema. I can't attempt to troubleshoot code
that I can't see.

Thanks for the response...
I have one table for permissions which has 'PermissionEntity' and another
table for contract which has 'ContractsEntity' .. the table I am currently
trying to remove my entry from is another table called permission_contract
which is shown below:

`.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
15 matches
