#1754

Changes

Allow constraining the allowed relations to an enum via the directive arguments relations and relationsEnum in @whereConditions and @whereHasConditions. This works analogous to columns and columnsEnum.

Breaking changes

None.

@LastDragon-ru please review.

Sorry for delay. Looks good I think 👍

I realized that this is nonsensical when combined with columnsEnum. The allowed columns of the original model are used for the relations as well.

We need to find a solution that either has a separate input that allows columns as strings for relations, or an even more sophisticated solution that has enums for the relations. Configuration could look like this:

@whereConditions(relations: [
  { name: "friends", columns: ["name", "age"] }
  { name: "friends.friends", columns: ["name", "age"] }
])

input QueryPeopleWhereWhereConditionsRelation {
  friends: QueryPeopleWhereWhereConditionsFriendsConditions
  friendsFriends: QueryPeopleWhereWhereConditionsFriendsFriendsConditions
}

input QueryPeopleWhereWhereConditionsFriendsConditions{
  column: QueryPeopleWhereWhereConditionsFriendsColumn
  operator: SQLOperator = EQ
  value: Mixed
  AND: [QueryPeopleWhereWhereConditionsFriendsConditions!]
  OR: [QueryPeopleWhereWhereConditionsFriendsConditions!]
}

enum QueryPeopleWhereWhereConditionsFriendsConditions {
  NAME
  AGE
}

Is this abandoned? Do we have a way to define the column names for relations?

You can try @searchBy directive ;)

Are there any chances of this being integrated into core?
