EntityDbExtensions

Simplify Entity Framework Delete Child Operations

Overview

Tired of manual and repetitive code when it comes to deleting child and subsequent objects with validations and nested loops? This library simplifies the process for you. By simply invoking a method in the .Update of the root class, it will automatically handle the recursive deletion of all child, grandchild, and subsequent objects that have been removed from your root class.

The method will inspect classes containing a virtual child property with a generic list type, such as IEnumerable<YourClass> or ICollection<YourClass>.

 public virtual IEnumerable<YourChild> YourChild { get; private set; }

It performs a validation check to determine if the object has been deleted, marking it as removed. This marking signals Entity Framework to handle the deletion seamlessly. The validation process is recursive, ensuring that all child and subsequent objects undergo thorough examination and validation for removal.

Features

• Effortless Database Operations: Streamline your Entity Framework database operations with simplified methods.

• Extension Methods for DbContext: Easily perform common database operations using intuitive extension methods on your DbContexts.

Getting Started

1. Installation:
   • Install the EntityDbExtensions NuGet package in your .NET project.

dotnet add package EntityDbExtensions


Usage:
Add the necessary using statement to your code.
Start using the extension methods on your Entity Framework entities.

using EntityDbExtensions;

 public async Task<bool> Update(YourEntity entity)
 {
    var entityDb = await Get(entity.Id);

    _yourDbContext.HandleDeletedChildren(entity, entityDb);  // Here the magic happens.

    _yourDbContext.Set<YourEntity>().Update(entity);
    return await _yourDbContext.SaveChangesAsync() > 0;
 }
