Hi,
I got "The DELETE statement conflicted with the REFERENCE constraint...." error when using Unit of Work Delete(TPrimaryKey id) function for my parent child data/table. The id that I passed in into the delete function is the parent id.
I understand that this is due to I tried to delete the parent without deleting the children. What is the correct way to do this?
I had also tried to use Delete(TEntity entity) and supply the entity with the parent object (children included), but still no luck.
var parentObj= _parentRepository.Get(parentId);
_parentRepository.Delete(parentObj);

Hi,
This is not a unique problem to ABP. If you don't use ABP and use plain EntityFramework, same will happen. So, what's the solution? There are some alternatives:
- You can define cascade delete in db level.
- You can delete children first.
- You can make the parent ISoftDelete.
All has advantages and disadvantages. There maybe other alternatives, these are what I'm making for such cases based on the case.
