Problem Description:
I created schem with table and view, which sum data group by foreign key (primary key of table mentioned before). The problem is, that when I edit table, everythings updates, but if I edit table that the view is based ofn nothing updates. I found example with views in project. After adding base_tables I can see that the trigger has sent data but I have an error. I think the problem is I dont have id in view, but in this case I cant add id.

Schem:

[
    {
        "database": "manager",
        "index": "testview",
        "nodes": {
            "table": "producttest",
            "primary_key": ["id"],
            "columns": [
                "id",
                "a"
            ],
            "transform": {
                "mapping": {
                    "id": {
                        "type": "keyword"
                    }
                }
            },
            "children": [
                {
                    "table": "reservation_view",
                    "base_tables": ["reservation"],
                    "label": "reservation",
                    "primary_key": ["user_id"],
                    "columns": [
                        "user_id",
                        "amount_reserved"
                    ],
                    "relationship": {
                        "type": "one_to_one",
                        "variant": "object",
                        "foreign_key": {
                            "parent": ["id"],
                            "child": ["user_id"]
                        }
                    }
                }
            ]
        }
    }
]

View:

create view reservation_view(user_id, amount_reserved) as
SELECT reservation.user_id,
       sum(reservation.amount) AS amount_reserved
FROM reservation
GROUP BY reservation.user_id;

Table reservation:

    id                                 uuid default uuid_generate_v4() not null
        primary key,
    user_id               uuid                            not null,
    amount                             integer                         not null,

Any ideas?

• I think its desirable to have a primary id field in the view.
• I could not figure out an elegant way to handle views without a primary.
• Perhaps this should be documented somewhere.
• Does it work as expected when you add a primary key to the view?

@toluaina Great work here could you please add documentation for using views
