Since this question got upvoted several times I would like to share what I did in the end: Since I had some more requirements to be implemented like security etc. I implemented a service layer which hides the domain objects from the controllers. I introduced a “dynamic DTO layer” which translates Domain Objects to Groovy … Read more
This is standard behavior in the Groovy shell, not peculiar to the Grails shell. You probably don’t want to def the variable. See the following: ~ $ groovysh Groovy Shell (2.3.4, JVM: 1.7.0_45) Type ‘:help’ or ‘:h’ for help. ——————————————————————————- groovy:000> def x = 42 ===> 42 groovy:000> x Unknown property: x groovy:000> y = … Read more
It seems that in Grails 2.3 the reloading is no longer the default In Grails 2.3 the reloading agent is no longer on the build system path unless you pass the -reloading flag to the grails command: grails -reloading run-app However, you can enable forking in your buildConfig using the following configuration: forkConfig = [maxMemory: … Read more
Default sort() is useful for Comparable object. If your class is not a Comparable, use: def orders = publicTrainingInstance.trainingOrder.sort { it.id } That code will sort by using passed id. See docs: http://groovy.codehaus.org/groovy-jdk/java/util/Collection.html#sort()
The grailsApplication object is available within services, allowing this: package example import com.example.ExampleApiClient; class ExampleService { def grailsApplication def relevantMethod() { def client = new ExampleApiClient( grailsApplication.config.apiCredentials.baseUrl grailsApplication.config.apiCredentials.username, grailsApplication.config.apiCredentials.password ) return client.action(); } }
the g:pageProperty is a very powerful, but very poorly documented thing. Lets say in my layout I specify where to put some content like this: <html> <body> <g:pageProperty name=”page.header” /> </body> Now in my page I can specify some content: <content tag=”header”> <!– header –> </content> Sitemesh will take the content tag, regardless of actual … Read more
Part 1: Hibernate does the right thing. The query cache is not per entity. There is a single query cache region, shared by all queries, unless you set a specific region for a query. Each time a table is updated, its timestamp in the timestamps cache is updated. Each time a query is executed, the … Read more
It’s the “Safe Navigation Operator”, which is a Groovy feature that concisely avoids null pointer exceptions. See http://docs.groovy-lang.org/latest/html/documentation/index.html#_safe_navigation_operator In this case, if phoneInstance is null, then it doesn’t try to get the name property and cause a NPE – it just sets the value of the field tag to null.
You can declare that in the mapping closure of your Domain class: static mapping = { myTextField type: ‘text’ } (See ORM DSL Documentation)
I have tried all mentioned here without success. The only helpful information is here. In essence you should disable forked execution by adding the following to grails-app/conf/BuildConfig.groovy: grails.project.fork = [ test: false, run: false ] Now debugging is available in IntelliJ IDEA Ultimate Edition v.12.1.6 just by ordinary Debug without Remote debugging. Tested on Grails … Read more
