Can not update relational column

hi
i have a relational column in my table that is related to another table that has some records
i want to add for example two of this record in relational column with Api but i cant
i try deep-save but it add new record in related table, i want to add existed record in my relational column

Hello @mohammad_amin_yanali

When you say:

what exactly do you mean:
Deep Save - Saving New Objects
Deep Save - Update with Adding a Relation
or
Deep Save - Update Parent and Child

i mean
Deep Save - Update with Adding a Relation

It looks like you forgot to add the object ID in the child object to determine what should be updated. If you do not provide it, the new record will be created.
