MongoDB: forced referential actions to prevent looping (target 3.7)

See original GitHub issue

Dev work is PR #2415 Per Flavian: Any MongoDB datamodel with self relations or cycles between 3 models will be forced to set some specific referential actions to prevent the referential action emulations from looping infinitely (eg: Cascade cannot work).

The rules and examples have already been all written for SQL Server here. And here

These limitations exist as soon as you enable the referentialIntegrity = "prisma" mode. Since it’s enabled for MongoDB by default, it’s the primary target for this change.

Proposal is that we create a different page based on the SQL Server one for the prisma referentialIntegrity mode and there explain how that affects MongoDB.

Note: The Multiple cascade paths between two models chapter do not apply though.

I think this has been merged and will be part of 3.7 indeed.

Let’s get #2581 over the finish line then to make this easier.

Thanks @janpio ! Good news, then @keerlu will merge #2581 Monday morning, and I will start a new PR for this work. (Yep, we could have made a PR on top of her PR, but I like the simplicity of first merging hers, then I do a separate one.)
