My latest project spend day with kids


Welcome to the grails tutorials powered by Grails. My idea is that with your help these pages will become home of the tutorial, how to and example links to articles on the web regarding Grails and Groovy. As you find interesting article, just paste link to that article here so the all community of Grails and Groovy practicioners can benefit from it. This way our knowledge will be focused and the Grails and Groovy community will be able to grow even faster.

As you probably noticed, in these few sentences, I have already mentioned tutorials, how tos, and examples many times. This is my view what should be posted under tutorials. Only articles that describe how to implement certain functionality using Grails or Groovy. Announcements, opinions and other type of articles are not tutorials. Of course, these articles are not forbidden but support for them will be added later.

If you have or know Grails or Groovy articles you would like to share it is enough to Register and start posting links to them.

My vision is to become one of the leading places for the Grails and Groovy practicioners. To undrestand how we can achieve this and also to learn basic ideas about this project read Vision section.

I wish you lot of successful Grails and Groovy projects :)

With Grails we get a lot of extra support for handling request parameters. We can convert a request parameter value to a specific type with a simple method invocation. Grails adds for example the method int() to the parameter so we can return the request parameter value converted to an int. Grails adds several methods like byte(), long(), boolean() we can use in our code.

This is a small issue, but I encountered it and found a solution on the mailing lists, so I thought I’d document it here. I was demonstrating a trivial Grails application in class today and decided to unit test it. The app has a single controller, called WelcomeController:

Grails provides a sound i18n mechanism, specific documentation to see if / grails-app/i18n directory will understand. The default will be generated in various languages of the properties file. In many parts of Grails and i18n related. These include the domain object constraints, the control layer returns an error message, gsp characters in the show.

Whew, Grails has some gotchas. It is so great for so many reasons. But WOW! There are some time sinks tucked away for you to discover. In the hope of helping others, here is a list of the ones that hit me.

It seems that the Groovy has a project for just about anything. That's one of the reasons why the language is so popular. The GPars library is an especially useful project in this new era of mult-core processors and concurrent programming. Formerly known as GParallelizer, GPars offers a framework for handling tasks concurrently and asynchronously while safe-guarding mutable values. DZone recently got an update on the project's latest news from project lead Václav Pech, and we've provided some examples of GPars concepts.
