soft-delete

问题 I want to delete an image every time I delete an item so I tried using an observer and put my code in deleted method, but I can't get deleted data although I'm using soft delete. I already try this in my observer, but it fail. public function deleted(Board $board) { $thisBoard = Board::withTrashed()->getDirty(); $imageName = $thisBoard['image']; Storage::delete("public/" . $board->getImageFolder() . $imageName); Storage::delete("public/" . $board->getImageFolder() . "thumbnail/{$imageName}");

问题 I am using Spring and Hibernate for my application. I am only allowing logical delete in my application where I need to set the field isActive=false. Instead of repeating the same field in all the entities, I created a Base Class with the property and getter-setter for 'isActive'. So, during delete, I invoke the update() method and set the isActive to false. I am not able to get this working. If any one has any idea, please let me know. Base Entity public abstract class BaseEntity<TId extends

问题 I found that the soft-delete in laravel Eloquent ORM is just replacing the null in deleted_at column by a timestamp. When querying a table with soft delete, is it just checking if the deleted_at is null, or it is really comparing the value with current time? I am asking to see if I am able to do schedule delete by setting a future time on the deleted_at column. 回答1: Laravel only checks if deleted_at is not NULL . SoftDeletingScope : public function apply(Builder $builder) { $model = $builder-

问题 I have a simple schema in which soft deletes are used (that's how it is designed and that can't be changed). There are two tables that participate in the schema: Company (id, is_deleted) and Employee (id, company_id, is_deleted) where company_id ofcourse is a FK to the Company table. The rules are: If a Company has is_deleted = true , then all Employee referring to that company should have is_deleted = true . But an Employee may have is_deleted = true even if the parent Company has is_deleted

问题 SQL has always had a great feature: cascading deletes. You plan it in advance and when it's time to delete something, BAM! No need to worry about all those dependent records. However, nowadays it's almost taboo to actually DELETE anything. You flag it as deleted and stop showing it. Unfortunately, I haven't been able to find a solid solution to doing this when there are dependent records. I've always manually coded the complicated web of soft deletes. Is there a better solution out there that

问题 I am trying to prevent any deletes on my database tables. Currently using Entity Framework 5. Firstly here is my code, public override int SaveChanges() { var Changed = ChangeTracker.Entries(); if (Changed != null) { foreach (var entry in Changed.Where(e => e.State == EntityState.Deleted)) { entry.State = EntityState.Unchanged; } } return base.SaveChanges(); } I've managed to prevent it with this way.
