Besides the sample applications featured in the books Beginning Groovy and Grails and The Definitive Guide to Grails, are there any applications out there written in Grails that are good examples from which to learn best practices? Such as real applications that are open-source?

During my learning phase, I came across several good sample applications.

This sample web album app got me started on grails. It covers security, image upload / manipulation, basic crud etc.

Here's one from Glen Smith, author of the upcoming Grails in Action book. The source code to the groovy blog aggregator is located here:

http://code.google.com/p/groovyblogs/

Here's another one by Glen, a blog engine written with grails:

http://code.google.com/p/gravl/

And finally, here's the code to the grails.org site which includes wiki functionality:

Yes. IBM has an excellent series of articles building on to a sample application at IBM's developerworks site:

If you are interested in seeing an application which is pre-built which also incorporates the Grails specific testing practices and approaches (as well as some widely practised testing methods as used within Grails), the Winelovers application outlines a fully working app and a number of different testing angles which can be applied to create confidence and increase testing coverage for your apps.

https://svn.energizedwork.com/skunkworks/grails/WineLovers/

There is also a presentation which accompanies this which goes into samples and pros and cons.

I will be following up this work with a greater number of examples and further tutorial type updates to help draw out the benefits of testing this way and this much.

I'm adding Stephane's new application to the list:

Stephane Maldini ✆ to user show details Oct 21 Hi folks,

I'm pleased to announce the release of a relatively big grails App called iceScrum (http://www.icescrum.org/demo). Code is under a mix of Apache Licence2 , LGPL and AGPL for the core views/design ( http://github.com/icescrum/iceScrum ).

What you can expect to see in this sample (and if you want to reuse the view taglibs behind (140 and more tags)

  • Jquery widgets : Tables, Postits, Windows, Widgets, Orderable Menu Bar, Drag And Drop, Key shortcuts .........

  • Real time push for jquery with ICEpush

  • Activity plugin ( "someone has done something")
  • AJAX paradigm for view (url is http://app/project/#view/action/id ) like GMAIL, history fully supported.
  • Application of SpringSecurity ACL, Springcache, Resources plugin and many others
  • Window/Widget paradigm on controller just by adding static ui = true (use icescrum Web Component plugins inside) It will be released separatly when time will come
  • Jasper integration
  • Jquery Chart integration
  • many many things which deserve a lot of documentation, at this time you will have to explore yourself some parts.

The app purpose is to offer to agile teams a tool to share a dashboard (for collaborative consultants etc), reports, stories, track bugs and so. It will have his own evolution + some profressional services for better integration in IT via plugins or simply hosting.

A very good series that builds a sample app: http://www.ibm.com/developerworks/views/java/libraryview.jsp?search_by=mastering+grails

I second the IBM series Ray Tayek mentioned, and the energizedwork.com example j pimmel mentioned. The latter has been my reference manual for writing well-tested code and I can't live without it.

The new (Grails 2.0) GEvents app from Paolo Foletto needs to be in this list. There are step-by-step apps leading to the complete app. https://github.com/pfoletto/GEvents/wiki/GrailsWorkshop

There's a working version at http://www.grailsworkshop.com/GEvents/.
