Angular - Part 1




What is Angular?
Angular is a platform that makes it easy to build applications with the web. Angular combines declarative templates, dependency injection, end to end tooling, and integrated best practices to solve development challenges. Angular empowers developers to build applications that live on the web, mobile, or the desktop.
Angular lets you extend HTML with HTML attributes called directives. Angular directives offer functionality to HTML applications. Angular is open source front end framework and it was written in Typescript. And it was built by developers of google.

Features of Angular.
Following are the key features of Angular:
  • Components − The earlier version of Angular had a focus of Controllers but now has changed the focus to having components over controllers. Components help to build the applications into many modules. This helps in better maintaining the application over a period of time.
  • TypeScript − The newer version of Angular is based on TypeScript. This is a superset of JavaScript and is maintained by Microsoft.
  • Services − Services are a set of code that can be shared by different components of an application. So for example if you had a data component that picked data from a database, you could have it as a shared service that could be used across multiple applications.

#EF : DbEntityValidationException - How can I easily tell what caused the error?

While calling  SaveChanges  on my  DbContext , I get the following exception: System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. This is all fine and dandy, but I don't want to attach a debugger every time this exception occurs. More over, in production environments I cannot easily attach a debugger so I have to go to great lengths to reproduce these errors. How can I see the details hidden within the  DbEntityValidationException ? Answer :  The easiest solution is to override SaveChanges on your entities class. You can catch the DbEntityValidationException, unwrap the actual errors and create a new DbEntityValidationException with the improved message. Create a partial class next to your SomethingSomething.Context.cs file. Use the code at the bottom of this post. That's it. Your implementation will automatically use the overriden Save...
