Grails Goodness: Customize the URL Format
Dec 27th
Starting from Grails 2.0 we can change the URL format in our application. Default a camel case convention is used for the URLs. For example a controller SampleAppController with an action showSamplePage results in the following URL /sampleApp/showSamplePage.
Grails Goodness: Get GrailsApplication and ApplicationContext in GSP
Nov 28th
Several variables are injected to Groovy Server Pages (GSP) in a Grails application. Two of them are the ApplicationContext and GrailsApplication objects. They are bound to the variables applicationContext and grailsApplication.
Grails Goodness: Access Action and Controller Name in GSP
Nov 25th
In our GSP views we can see the name of the action and controller that resulted in the view. We can use this for example to show or hide certain information based on the values for the action and controller name. Grails injects the variables actionName and controllerName automatically and sets the values based on the action and controller.
Grails Goodness: Internationalize Javascript Messages with JAWR Plugin
Nov 14th
Grails has great builtin support for internationalization (i18n). The underlying Spring support for i18n is used. We can easily change for example text on views based on the user’s locale. But this only applies for the server side of our code. So we can generate the correct messages and labels based on the user’s locale on the server, but not in our Javascript code. What if we want to display a localized message in a bit of Javascript code, that is not created on the server? Why do I add this extra information ‘not created on the server’? Because we can still generate Javascript code in a view or use the gsp-resources plugin to create Javascript on the server. This code can contain the output of a localized message and can be used in Javascript. But that is not what we want for this blog post. Here we are going to reference our i18n messages from plain, non-generated Javascript code.
Grails Goodness: Use a Different jQuery UI Theme with Resources Plugin
Oct 25th
The resources plugin is a great way to manage resources in our Grails application. We define our resources like Javascript and CSS files with a simple DSL. The plugin will package the resources in the most efficient way for us in the final application.
Gr8Conf 2011 Conference Report: Day 2
May 20th
After already a first great university day it was now time for the official start of the conference days. After Søren’s welcome speech it was for time for Guillaume Laforge to present his brand new presentation about Groovy 1.8. He touched on all the interesting new features we can find in Groovy in his presentation.
The new command chain expressions even allows us to leave out dots when we invoke methods so we can write even nicier and more natural language like DSLs. A lot AST transformations have been added in Groovy 1.8, closure methods, JSON supports, compilation customizers and much more. The slides are available on SlideShare.
Gr8Conf 2011 Conference Report: Day 1
May 20th
For the first time this year Gr8Conf organized a university day. On this day 3 hour sessions where given about Groovy (in the morning) and Grails (in the afternoon). In the morning I did the session about Getting Groovy together with Søren Berg Glasius (one of the organizers of Gr8Conf). We had a lot of topics to cover and didn’t make it to cover it all during the session. Luckily we created a big document with all the topics and a lot of sample code (also from the Groovy Goodness blog series) for the attendees. So hopefully people will look into the document to learn more about the topics we couldn’t cover.
Continuous deployment Grails Apps with Cloudbees Jenkins GitHub
May 16th
After deploying Grails Apps to Amazon Beanstalk, it’s now time to look at CloudBees. At the moment CloudBees offers the only Platform as a Service (PaaS) that spans the complete develop-to-deploy lifecycle of Java web applications in the cloud; without any servers, any virtual machines or any IT staff. See the Cloudbees website for more info. For a random Grails App named ‘KnowledgeMatch’ we follow some simple steps:
