Monorail Introduction

An Introduction to Monorail.
Andrea Magnorsky
An Open Source MVC framework

Monorail
Open Source
MVC on top of Asp.Net
Separation of Concerns
Mature
Convention over configuration

What am I showing
Monorail: MVC framework
With a model implemented using Active Record
With Windsor integration. Windsor is an inversion of control container.
Using Nvelocity as a view engine.
Why am I showing all this? Because although they are separate components they work nicely together.

How Monorail works

Build it and they will learn it?
Twitter App
User can send Updates
User can follow other users
Lets see the Demo

Model
Uses Active Record
Convention over Configuration
Default set of operations
Works on top of Nhibernate
You dont have to use ActiveRecord.
Lets look at the code for the model
* * *

Controller
Orchestrates the application flow.
Convention is <name>Controller ( ie HomeController)

Actions
Corresponds to methods in the controller.
Corresponding view (in Views/<controller name>/<action name>) Can be changed
Example: /Login/Login.rails

Layouts & Rescues
Layouts.
Not mandatory, use as template.
In Views/Layouts
Rescues. To Handle exceptions

SmartDispatcherController
Databinding. Parameters as strongly typed objects

Controller
Filters.
Executed Before or after an action
Normally used for Authentication, logging
Associated with a controller

Controller
Helpers
Associated with controller. Available in the view.
There are many helpers. (FormHelper, UrlHelper)
You can create your custom Helper

PropertyBag
The standard way to pass information from the controller to the view
Not Strongly Typed

Flash
A way to persist information between requests
Normally used to retrieve information about an operation to a user, for example on error.

Windsor Integration
Windsor is an Inversion of Control (IoC) container.
Promotes loose coupling
Makes you write small classes that have a well defined responsibility.
Without the integration you can use windsor (or other IoC) for services, but its more coupled.
Without it, controllers coupled to services and possibly IoC container

Windsor Integration

Controller Testing
Careful you don't test the framework
Controllers should be skinny

Views
View Engines
Nvelocity
Brail
AspView
Others (contributed by Users)
Layouts. Template views that define the layout
Rescues

Deployment
IIS
Cassini (only for early development )
Monorail can be run on Mono via Apache
Some Tweaking normally required
Monorail applications can also be run on the cloud (like EC2 instances)
