Register Repository Implementations Automatically with Windsor

Fri, 27 Feb 2009 00:03:17 GMT

It is common in a domain driven design project to want to register all the implementations of IRepository<> by convention. There may be interfaces that inherit from IRepository<> such as ICustomerRepository inheriting from IRepository<Customer>. This article provides a Castle Facility that takes as its configuration parameters the base type of the repository (IRepository<>) and a group of assemblies to search. It registers implementations of the IRepository interfaces both for the generic type and for the more specific type. You would therefore be able to, in our example, retrieve CustomerRepository (implementation of ICustomerRepository) by resolving IRepository<Customer> or ICustomerRepository. If you practice DDD and are using Windsor as your Inversion of Control container, this may be useful to you. If you use a different inversion of control container, the approach could be adapted to your needs.

The State Pattern

Tue, 02 Sep 2008 02:21:38 GMT

An introduction to the State Pattern: a behavioral design pattern that allows an object to partially change its type at runtime. The state pattern is a subset of the strategy pattern. The state pattern has a variety of uses, not least amongst them helping to encapsulate state changes of NHibernate persistent entities ssince it is usually undesirable to have a persistent entity change its type. The state pattern will also help you avoid brittle switch statements in domain logic.

Forms Validation Framework for ASP.NET MVC

Tue, 12 Aug 2008 00:31:10 GMT

A reusable technique and sample project detailing how to use POCO models to generate forms and perform validation upon them. The forms helper class can be used as parameters to action methods via an action filter providing seamless integration with the MVC framework. Generate, render, and validate forms based upon POCO objects quickly and easily.

MVC Routing For Specifying Response Type

Wed, 30 Jul 2008 07:35:25 GMT

This is a post I wrote about providing a response type based upon the extension used in a route for MVC routes. Example URLs: /Category/Show/1 /Category/Show.xml/1 /Category/Show.json/1 With this approach, in your controller, RouteData["responseType"] will default to html or if a different extension was added to the action, then it will reflect that extension. This allows nice URLs for services wanting to access your actions as services that provide json, xml, or whatever else you might desire to return.

Brackets, braces, parentheses, and other such creatures

Tue, 29 Jul 2008 08:29:49 GMT

An interesting story about a common task in text-manipulation done with TDD. The problem is stated as such: This aim of this challenge was to determine whether any given string has a legal bracket structure. Basically, make sure all the '(', '[', '{', and '<' have matching ')', ']', '}' and '>'. We also need to take nesting into account, so that "({)}" is incorrect, and "({}<{}>)" will pass.

Domain Specific Language using Rhino DSL and Boo

Wed, 25 Jun 2008 00:40:00 GMT

A C# implementation of a domain specific language for configuration of a new open source project: mite. Rhino.DSL is used to create a DSL to define migration environments. The syntax for the Boo based DSL is concise and allows the configuration to be kept DRY. There are many advantages to using DSL over XML configuration. See how quick and easy it is to build your own DSL. Sample project is included.
