Question
I'm working on asp.net core webAPi and EF core, and want to implement "update" operation (partially edit entity). I searched the correct way to deal with that, and saw that I should use jsonPatch. the problem is that I'm expose just DTOs through my API, and if I use jsonPatch like:
public AccountDto Patch(int id, [FromBody]JsonPatchDocument<AccountDto> patch)
then I need to apply the patch on DTO, and I can't apply it on the model entity, without create a new entity.
I also read about Odata.Delta, but it still not work on asp.net core, and furthermore - I don't think it has a built in solution for working with dto (I found this example that can help when Odata for core will be available)
So, for now - should I use POST and send DTO with list of changed properties in query (as I saw here), Or - there is more elegant solution?
Thanks!
Accepted Answer
Now I saw that using autoMapper I can do just
CreateMap<JsonPatchDocument<AccountDTO>, JsonPatchDocument<Account>>();
CreateMap<Operation<AccountDTO>, Operation<Account>>();
and it work like a charm :)

Eventually,
I just remove the type from JsonPatchDocument, and saw that it can work without type...
[HttpPatch("{id}")]
public AccountDTO Patch(int id, [FromBody]JsonPatchDocument patch)
{
return _mapper.Map<AccountDTO>(_accountBlService.EditAccount(id, patch));
}
And then, In BL layer,
public Account EditAccount(int id, JsonPatchDocument patch)
{
var account = _context.Accounts.Single(a => a.AccountId == id);
var uneditablePaths = new List<string> { "/accountId" };
if (patch.Operations.Any(operation => uneditablePaths.Contains(operation.path)))
{
throw new UnauthorizedAccessException();
}
patch.ApplyTo(account);
return account;
}
