concurrency exception with a detached entity
We are creating an API, to delete an entity in the endpoint we only receive the Id and attach a new entity to avoid doing a search in the database
Controller:
[HttpDelete("id:guid")]
public async Task<IActionResult> DeleteAsync([FromRoute] Guid id)
Repository:
var document = new Document
Id = id,
DeletedAt = DateTime.UtcNow,
;
this.CrmContext.Attach(document);
this.CrmContext.Entry(document).Property(p => p.DeletedAt).IsModified = true;
await this.CrmContext.SaveChangesAsync().ConfigureAwait(false);
The problem is that we added a RowVersion column and this throws a DbUpdateConcurrencyException, in all the examples and responses similar to this question the answer is to read the value from the Database first.
Is there a way to make this work without querying the database first?
Thanks
