How to soft-delete in Keystone 6? Hooks not working.

[chriseaton]

I have a list that is correctly capturing the beforeOperation and checking for a delete, then updating instead, as most guides seem to indicate, however, this isn't preventing the record from being subsequently deleted. I don't know if this is a bug or something I'm missing but I can't seem to be able to soft-delete a record without errors being thrown which is not ideal (it should be a seamless "delete" from the user perspective.

Has anyone been able to do soft-deletes with keystone 6?

hooks: {
        beforeOperation: {
            delete: async (op) => {
                if (op.operation === 'delete') {
                    await op.context.db.organization.updateOne({
                        where: { id: op.item.id },
                        data: { date_deleted: new Date() }
                    });
                    op.operation = 'update';
                }
            }
        }
    },

...throws error on screen in the UI, then deletes the record anyways.

I tried with and without the op.operation modification. It does prevent delete if I throw an error... but that defeats the point, I don't want an error bubbling to the user - I just want a seamless soft-delete!

one way to do that is to create a custom mutation which overrides delete mutation for your list. We have done that in a project.

How were you able to override the original mutation? I tried, and it just returns an error:

Error: The schema extension defines a field "deleteorganization" on the "Mutation" type but that type already defines a field with that name.
The original field:
deleteorganization(where: organizationWhereUniqueInput!): organization
The field added by the extension:
deleteorganization(where: organizationWhereUniqueInput!): organization

Edit: Nevermind, had to use the mergeSchemas approach, as described here:
