Hi group, i need your help and advices, i want to add a simple method to a domain class something like

def fullName = {
    return firstName + " " + lastName
}

is this a correct implementation and is this a best practice?

Thanks from now!

Hi,

Your implementation is correct but you can get more GString, return statement is optional and use a normal method : 

String fullName()  {

  "$firstName $lastName"

}

but closure will also work

It's perfectly valid to add methods to domain classes. But that's not a method, it's a Closure.

This is how I'd do it:

   String fullName() { "$firstName $lastName" }

As others have commented, you are not using Groovy idioms and you've defined a closure instead of a method.  You should do:

def fullName { "$firstName $lastName"}

A good Groovy book can help you develop good Groovy idiom.

You may want to add it to transients also so that GORM doesn't try to save your derived field.

    static transients = ['fullName']

If you make the method getFullName() { "$firstName $lastName"}
You can refer to it as myDomainInstance.fullName. You also don't need to add this to transients. As I understand it only if add both a getter and a setter would you need to add it to transients. I have several methods in my domain classes defined as getSomething() and don't add them to transients with no problems.

[sethfuller]

I forgot the return type, so the method would be:
String getFullName() {"$firstName $lastName"}

[chichibek bros]

some days ago a symfony framework developer friend told me if in grails is there a place were you can create all sql queries and call it like getAllSomething() but not in controllers after some of your answer i was wondering if the domain class is that place?

I didn't realize that was only 2.0+. I guess that's why you didn't suggest it in your original answer.

[sethfuller]

It may depend on your version of Grails. I know in 2.0+ it is good to have getAllSomething() type methods in domain classes.
