I had no idea on how to do it but I think I have just solved it and I am sharing it with you and I think I will stop saying that I am not a Java person as Groovy and Grails stuff is pushing me into both Java and its ecosystem.

The best example for explaining this would be security. Imagine you have a controller class that you don't want your regular members to access so you add @RequireRole("Admin") above your controller class. Whenever a member tries to access that annotated controller class they will be redirected to an unauthorized page unless they are admin.

I have created an action in my TagController called tagIndex which displays all the tags. So far so good. However I need to count how many posts a tag has. Surely I can implement this with the following:

def tagList = Tag.list()
tagList.each { println "${it.tagName() (${it.posts.size()})" }

The code above will select all the tags from the database and will do a count query on all tags you will display. Absolutely a blood thirst.

I have compiled some of the available videos on Groovy and Grails to get you in the right direction.

Skills Matter: Groovy & Grails Exchange 2010

The latest information and talks about Groovy and Grails world. This event did take place in London on 16 - 17 December 2010. You will watch the talks about latest development events on Groovy and Grails. All of the talks are really great and must watch!

I was going to build this CMS with Yii framework however I have changed my decision. The CMS will be developed with Grails and Qooxdoo. The whole application will rely on Grails and for the admin panel instead of getting busy with lots of front-end stuff I will use Qooxdoo.

Let me introduce my tools for the job first. Qooxdoo is a great JavaScript framework which lets you create rich internet applications with its impressive GUI toolkit. Grails, on the other hand, is a great web framework which you use Groovy with and runs on top of the Java Virtual Machine. Both of these two frameworks are open source, under active development and very open to improvements.

I wanted to create permalinks or slugs of the questions for the urls. Since I already had the regular expression for this -I'm using it on this blog- all I needed to know how to use it with Groovy.

The solution is simple as always. There is nothing hard in programming. Anyway, solution is here.

After a long time I heard there is something called web framework and then I wanted to learn the best one for me. I have reviewed and learned many frameworks and because of the fact that I'm a grasping person, I have learnt more than just one. Is this a mistake? A part of me says yes and another part says it's not a mistake. Both have reasons. So in this post, I will try to write a simple and short guide for people who are desperately unstable on choosing a web framework.

So far it's going good. Ofcourse open source! :) I needed to use markdown with Grails, there is a plugin for that but it requires Grails 1.2 which is unstable. And then I remembered that I could use Java libraries with Grails since it's based on Groovy.

Grails needs no configuration, it is just a full stack web framework which you can install and start creating projects. However if you are willing to use MySQL with your Grails project then you need to make some configurations that will not take even two minutes.

Since I don't like Java I thought I could give a try to Grails as it is built on Groovy which runs on JVM. This is a simple tutorial that I explain how to create a very simple Hello World application with Grails.
