How can I get a map of the key/values of only the user-defined properties on one of my domain objects?
Problem is if I do this myself, I get my properties plus class, metaClass, constraints, closures, etc...
I assume Grails can do this fairly easily because it is done at some level in the scaffold code right? How can I do this myself?
Try this
class Person{
String name
String address
}
def filtered = ['class', 'active', 'metaClass']
def alex = new Person(name:'alex', address:'my home')
def props = alex.properties.collect{it}.findAll{!filtered.contains(it.key)}
props.each{
println it
}
It also works if you use alex.metaClass.surname = 'such'
. This property will be displayed in the each loop
This is an old question, but I just ran across this requirement and found another solution that is worth answering here for others who come across this thread. I have put together an example based on that thread:
Sample Bean
class SampleBean {
long id
private String firstName
String lastName
def email
Map asMap() {
this.class.declaredFields.findAll { !it.synthetic }.collectEntries {
[ (it.name):this."$it.name" ]
}
}
}
Test Class
class Test {
static main(args) {
// test bean properties
SampleBean sb = new SampleBean(1,'john','doe','[email protected]')
println sb.asMap()
}
}
The SampleBean
I put a variety of fields to show that it works, this is the output of the println:
[id:1, firstName:john, lastName:doe, email:[email protected]]
