tellesleandro Comments - Answer Overflow

The lack of this functionality in Ash sounds like I'm doing something wrong, but what I need is just as simple as a SELECT COUNT. Why this is not possible? Thanks for your support.

Something like SELECT COUNT(*) FROM parked_cars WHERE timestamp_field BETWEEN start_time AND end_time. start_time AND end_time are set by the user.

There is a dashboard that shows the amount of cars parked in a parking lot in a day. The table is parked_cars and it has a timestamp field (the time the car arrived at the parking lot). I have to count how many cars is parked during a timespan.

There's no parent relationship. It's a simple SELECT COUNT(*) FROM table.

Thanks. I tried, but I'm still stucked. Maybe I missed something. Could you give an example how to write these queries: "SELECT COUNT(*) FROM table" and "SELECT MIN(field) FROM table"?

belongs_to does not add _id attributes do resource

Just a note: the doc (https://ash-hq.org/docs/dsl/ash-resource#relationships-belongs_to) say that belongs_to "creates a field on the resource with the corresponding name and type, unless define_attribute?: false is provided". It makes me think that, by default, belongs_to takes care of all the configuration.

belongs_to does not add _id attributes do resource

I have some forms that collect information about one resource and its "children" (as post and comments), than I have to insert in the database the resource (post) and all its children (comments) at once (in the same db transaction). Is Ash able to do it? How?

Yes, I tried that and it works. Thanks. Is this the right thing to do to insert a resource and its relation at once?
