I found myself in exactly that position this week, and discovered that it (like most things in grails) was rather simple to accomplish. Considering I work in a predominately Java environment, I often need to run a java web application side by side with my grails work. To date, I would simply run grails Rich Krollhttp://www.blogger.com/profile/16813942547195314076noreply@blogger.com8tag:blogger.com,1999:blog-5372376616325579954.post-45872445779976443322009-11-27T13:37:00.005-05:002009-11-27T13:44:50.108-05:00Easy in-place delete with ajax and grailsI was recently asked to implement new delete functionality on a list of items. The catch of this request was that the removal of an item would be done without reloading the page. This required me to write a boatload of code in both JavaScript and Java to successfully implement. After this somewhat painful experience, I wanted to see how elegantly this experience would be handled in grails.

If a unit test extends GroovyTestCase, it can be run from groovy.
class GroovyTest extends GroovyTestCase {
void testString {
assertEquals 'Test failed!', "Test", "Test"
}
}
To execute this test, run the following command:
$ groovy GroovyTest.groovy
Time: 0.125
OK (1 test)

In my current project I found it necessary to enforce a constraint that a date be in the future. My first reaction was along the lines of "no problem, I'll just validate the data in the business tier", and then luckily discovered a much more elegant solution in grails: Rich Krollhttp://www.blogger.com/profile/16813942547195314076noreply@blogger.com2tag:blogger.com,1999:blog-5372376616325579954.post-68832933950491788622009-11-07T10:55:00.004-05:002009-11-13T15:09:48.321-05:00Grails 1.1, integration tests, and unsaved transient instance errorsIn the grails documentation, and every book on the subject you will find an example similar to:
class Author {
static hasMany = [ books : Book ]
String name
}
class Book {
static belongsTo = Author
Author author
String title
}
The belongsTo reference ensures that saves, updates, and deletes are cascaded. All the information that I have found provides an example to save your Rich Krollhttp://www.blogger.com/profile/16813942547195314076noreply@blogger.com0tag:blogger.com,1999:blog-5372376616325579954.post-28315015498902649532009-11-06T23:01:00.001-05:002009-11-13T15:10:03.913-05:00The Grails journey beginsAfter working with ColdFusion and becoming frustrated with some of it's shortcomings, I decided to use a "grown up" language; Java. It's been quite a few years since I made the leap to Java, and it has been a very interesting journey. I have had the "pleasure" to work with many different frameworks, tools, and technologies. With each I began with the same goal: to find an easierRich Krollhttp://www.blogger.com/profile/16813942547195314076noreply@blogger.com5
