AfterDelete Hook only works with a Delete(&struct) with a struct with PK value populated

[keif888]

Explain your user case and expected results

When executing a Delete() via GORM, the AfterDelete hook will fire. What the AfterDelete hook receives is the struct that was in the Delete().
If a Where("id=?", 10).Delete(&struct{}) clause is used or an ID is populated via Delete(&struct{}, 10) then the AfterDelete receives an empty struct.

The documentation on gorm.io should reflect what AfterDelete receives so that developers can use AfterDelete appropriately.

• Use Case 1 - Struct populated with ID
  • AfterDelete is called ONCE and receives the struct with ID (and other fields if provided), UpdatedAt, and DeletedAt populated
  • Test structdelete shows this
• Use Case 2 - Struct without ID, and list of ID(s) provided in delete conditions
  • AfterDelete is called ONCE and receives the struct without ID (but other fields if provided), UpdatedAt, and DeletedAt populated
  • Test structdeletebyid shows this
• Use Case 3 - Empty Struct, Delete using Where clause
  • AfterDelete is called ONCE and receives a struct with UpdatedAt, and DeletedAt populated
  • Tests singledeletebyid, singledelete and bulkdelete shows these
