In the midst of developing an Angular (v6) project in conjunction with ASP.NET MVC for backend and Entity Framework, I often encounter CRUD operations that involve updating only a handful of fields within an entity. This presents a dilemma in terms of determining the most suitable approach to adhere to best practices for such scenarios. To illustrate, consider an Employee entity with properties like Id, Status, Name, Surname, Job, Department, HireDate, BirthDate, Address, and Updated.
For instance, when dealing with updates to the Status, Department, and Updated fields, there are various approaches that can be taken:
Approach I:
The first method involves creating an instance of employee.ts and populating it in component.ts with only the relevant fields for update. This instance is then passed to service.ts, followed by Controller.cs. Within the controller, the model is received as an Employee entity where the Updated field is set before passing the entity to Service.cs for saving using EF methods.
Approach II:
Alternatively, only the Id, Status, and Department values are sent from Component.ts to service.ts, which are then passed on to the controller as int values (Id's). The controller instantiates a new version of the Employee.cs entity, fills in these three fields along with the Updated field, and passes the entity to Service.cs for saving via EF methods.
Approach III:
This method mirrors Approach II up until Controller.cs. Subsequently, the 3 parameters are forwarded to Service.ts, fetching the corresponding Employee from the database based on the Id parameter. Following this retrieval, the remaining fields are set and the entity is saved.
While all three approaches are viable, selecting the optimal one for Angular projects utilizing EF remains ambiguous. Any insights or recommendations pertaining to this scenario would be highly valued...
