Re: Refactoring Day 9 : Extract Interface

I appreciate you want to bring understanding to the developers, but you misunderstood the poinf of this refactoring.

Both the first and the second version of the RegistrationProcessor are equally decoupled from the type of the object called registration in your example. In other words the RegistrationProcessor does know nothing about the actual implementation of the Create method in any of the cases. Moreover it is not aware of the fact that ClassRegistration is declared as a class (and not an explicit interface).

Note that every Class exposes its interface implicitly, and the outer classes can refer to the actual implementation only through this implicit interface.

The real value of the example you provided is that you are able to limit the interface exposed by ClassRegistration to a subset interface that provides operation used for example by a Registration Processor. And this exaposes the type naming issue that was introduced to your example.

The original ClassRegistration should be named sth like ClassManagement and the extracted interface: ClassRegistration (drop the I as this bring no value to the type name).

also see the original Fowler's example: http://martinfowler.com/refact...

Since it can be difficult to find human opponents for a face-to-face game and I don't like playing against the computer, I will have to try out the internet chess site. Thanks for the info.

Derive your migrations from AutoReversingMigration

As Sean says, FluentMigrator (FM) isn't concerned with what ORM you are using, but I thought I'd share how I'm using FM with the EntityFrameworl (EF) 4.1.

Basically I've created a custom IDatabaseInitializer that creates a RunnerContext and then spins up a TaskExecutor to execute it. So when ever my web application starts up, it'll run any migration automatically.

It works great for my little project!

How can I run the migrations from my unit tests?

Can it generate Down actions based on Up actions (at least for CREATE)?

Looks very promising and I'm glad to hear that the project is gaining momentum. I hope that you get around to writing a post as to how one might approach deployments with this tool. Certainly there are many considerations that would depend on one's environment, but I would be interested in hearing/reading about your experiences and approach regarding deployments with FluentMigrator. Keep up the good work.

That would work as well.

However, FM supports many more databases than only sql server as stated in the post. The link you posted will only work for MSSQL.

In addition, I personally don't like writing sql. I rather write code that I can easily parse to sql.

Personal preference I guess.

Wes Mcclure — Wed, 06 Apr 2011 01:41:46 -0000

FWIW: why reinvent the wheel when we have SQL for migrations?

We wrote and use this and it's worked for every scenario we have ever conjured up in SQL Server: http://tsqlmigrations.codeplex...

It's just a wrapper around doing things via the SMO api and writing migrations as sql scripts.

Re: FluentMigrator getting started

seanchambers — Mon, 04 Apr 2011 18:15:09 -0000

FluentMigrator really isn't concerned with what ORM you are using. It meets the need of versioning your database schema. It is used to take snapshots of your schema at specific points. Your orm however will change as your entities change.

I guess I don't see your point or how fm would fit into EF. Can you elaborate?

Does FluentMigrator work with Entity Framework 4.1 Code First? If it does, I think MANY developers (including myself of course) would be VERY thankful!!

Well done guys, keep it up!

Great project and I should say I like the codebase. We're using dbdeploy currently, apparently we will migrate to fluentmigrator :)
