如何级联SoftDelete?

问题描述

在检查了这些SO文章之后: cascade-delete-in-entity-framework ， ef6-1-soft-delete-with-cascade-delete ， cascading-soft-delete ，和reasons-for-cascading-soft-deletes 并没有找到解决方案...

After checking these SO articles: cascade-delete-in-entity-framework, ef6-1-soft-delete-with-cascade-delete, cascading-soft-delete, method-for-cascading-soft-deletes-in-parent-child-relationships and reasons-for-cascading-soft-deletes and not finding a solution...

我让SoftDelete用于我的实体模型.我在上下文中覆盖了SaveChanges():

I have SoftDelete working for my Entity Models. I have overridden SaveChanges() in my Context:

    public override int SaveChanges()
    {
        ChangeTracker.DetectChanges();

        foreach (DbEntityEntry<ISoftDeletable> entity in ChangeTracker.Entries<ISoftDeletable>())
        {
            if (entity.State == EntityState.Deleted)
            {
                entity.State = EntityState.Modified;
                entity.Entity.IsDeleted = true;
            }
        }
        return base.SaveChanges();
    }

我为孩子实体设置了CascadeOnDelete.因为我覆盖已删除的EntityState，所以它不会级联.有谁知道将导航属性仅放在foreach循环中的方法吗?还是处理SoftDeletes的更好方法?

I have set CascadeOnDelete for my Child Entities. Because I override the deleted EntityState it doesn't cascade. Does anybody know a way to put only the Navigation properties in a foreach loop? Or a better way to handle SoftDeletes?

先谢谢您

推荐答案

阅读此SO文章后 ...

After reading this SO Article entity-framework-6-code-first-cascade-delete...

我意识到，我正在像这样抓取并删除我的实体:

I realized, I was grabbing and and deleting my entity like this:

var entity = context.Parent.FirstOrDefault();
context.Parent.Remove(entity);

当我需要像这样抓取整个图时:

When I needed to grab the entire Graph like this:

var entity = context.Parent.Include("Children").FirstOrDefault();
context.Parent.Remove(entity);
