Ramses

Lifecycle hooks for EF Core. The project is licensed under the MIT license.

Getting started

1. Install the package from NuGet
2. Make your DbContext extend from LifecycleDbContext
3. Call the SaveWithLifecycles or async variant to allow hooking into the lifecycle
4. Make your model(s) implement one of the provided lifecycle interfaces

Which version should I install?

If you are targeting .NET Core 2.*, then install version 2.* by invoking Install-Package Ramses -Version 2.0.1. Targeting .NET Core 3.*? Install version 3.* by invoking Install-Package Ramses -Version 3.0.1

Possible lifecycle hooks

Lifecycle hook	Interface
Before adding the model to the database	Com.Setarit.Ramses.LifecycleListener.IBeforeAddingListener
Before deleting the model from the database	Com.Setarit.Ramses.LifecycleListener.IBeforeDeletionListener
Before updating the model in the database	Com.Setarit.Ramses.LifecycleListener.IBeforeUpdateListener
After adding the model to the database	Com.Setarit.Ramses.LifecycleListener.IAfterAddingListener
After deleting the model from the database	Com.Setarit.Ramses.LifecycleListener.IAfterDeletionListener
After updating the model in the database	Com.Setarit.Ramses.LifecycleListener.IAfterUpdateListener

☝️ Caveats

Lifecycle hooks after saving to the database

When implementing one of the IAfter* interfaces, beware that the object will be in the same state as before saving to the database. If you change a property in for example AfterUpdate, this change will not be present in the database. To make sure the update is saved in the database, call SaveChanges().

Calling SaveWithLifecycles within the lifecycle hook

This may result in unexpected changes. Currently you cannot call SaveWithLifecycles or SaveWithLifecyclesAsync within the lifecycle hook. If you want to save the changes you made to the model within the lifecycle hook, call SaveChanges().
