What is REST?

Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. As such, it is not just a method for building "web services." The terms "representational state transfer" and "REST" were introduced in 2000 in the doctoral dissertation of Roy Fielding,[1] one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification.

REST is a method of managing resources over HTTP. There are a number of methods of interacting with resources via REST.

HTTP CRUD
POST Create
GET Read
PUT Update, Create
DELETE Delete

Systems which follow Fielding’s REST principles are often referred to as "RESTful".

JQuery has simplified a lot of my day to day coding. I think it is an amazing little framework and apparently a lot of people do too. Even Microsoft is bundling it with its ASP.NET MVC framework which , as far as I know, a first for open source software. Beyond even handling all the all of the cross browse mess, my favorite part of jQuery is the ability to easily extend the framework through plug-in. That brings us to the topic for this post. We are going to look at how easy it is to create a plug-in for jQuery.

What Will Our Plugin Do?

For this post I want to pick something that is fairly simple yet demonstrates the power of plugins. For this post I am going to show you how to create a plug-in that will highlight keywords in a given block of text. Many websites use something similar when performing searches.

Tab menus are a fairly common thing that I use in a lot of my applications. I like tabs because they help break up large chunks of, usually, related information.

 

At work we use RadControls for Telerik and they have a pretty nice tab menu control that is easy to use and looks good too. The only problem with these controls is that they only work in WebForms like even the default ASP.NET controls. So when I started playing with MVC I quickly realized I would need to spend some time building some of these controls myself.

In this post I want to show you how to use jQuery to create an AJAX login screen. I am going to use an ASP.NET MVC application for this demonstration. I will be modifying the small default application that is created when you create a new MVC application. So go ahead and create a new MVC application. I will be walking through the process step by step so when this article is done you will have a working application.

Well we’ve arrived at the last part of our series on ASP.NET MVC. In this post we’ll be looking at Views, ViewData, and HTML Helpers. We’ll be discussing how to call Views from Controllers and how to use HTML Helpers to create your markup.

 

Views In A Nutshell

Suppose we receive the following request; http://yourdomain.com/Task/Show/23. The request would map to the following controller.

   1: public class TaskController : Controller 
   2: { 
   3:     public ActionResult Show() 
   4:     { 
   5:         return View(); 
   6:     } 
   7: }

So far we have looked at the requirements for our fictional application and the data structure that goes with that, the application’s Model using a repository pattern , and URL Routing to provide friendlier URLs.

What we have covered so far really is just supporting code. In this post we’ll look the first of two parts that really hold our application together, the Controller. In the next post we’ll cover the View and how it ties into the Controller.

We have been looking at all the parts that make a sample ASP.Net MVC application. Previously we have discussed the database schema of our application as well as implementation of the Repository Pattern with filters on that schema. If you haven’t been following this series of posts you might want to read parts 1 and 2 before continuing. Url Routing has become a very common these days. In fact, at least among the websites I visit, it has become more common than not routing urls.

In the first part of this series we didn’t really look at the MVC framework. We talked about what it is and what it does but didn’t look at any code. We did however plan out what we wanted our application to do and created our database schema that will support our application. In this part we are going to jump in and get an MVC Application created and look at the Model portion of the application. We’ll create our domain objects and data repositories. It is important to note that I will be using the Repository Pattern with Pipes and Filters Pattern. So we’ll have our data repositories and their relevant filters. We will then create data service objects that encapsulate the repositories. Also, I will be using LINQ To SQL to interact with the database. If you prefer a different method of data access feel free to use something else. Finally, before we get started, I will not be writing unit tests for this series, at least not showing them in the posts, in order to keep things simple and to keep the posts from getting too long.
