Domain class not accessible in my controller

Question

I'm new to Grails and groovy..
I created a domain class

\grails-app\domain\Abc

Now i created a controller in

\grails-app\controllers\myapp\myController

In that, when i created an object it shows error.

def Abc obj = new Abc

The error i got is

unable to resolve class Abc 

I tried to import, but didn't shown there also. Me working in grails 1.3.7 and IntelliJ IDEA 10.0.2
Thank you

Answer 1

Make sure that the location of each class is consistent with the class and package declaration.

I created a domain class

\grails-app\domain\Abc

This class should look like this

class Abc {
    // implementation omitted
}

make sure you have no package declaration, because based on the location, this class should be in the default package (which is actually a bad practice). Ideally you should put this class into a package, then move the source file into a subdirectory of \grails-app\domain that corresponds to the package name.

Now i created a controller in

\grails-app\controllers\myapp\myController

This class should look like this

package myapp
  
class myController {
    // implementation omitted
}

Notice that this class should be named with a lower-case 'm' because that's how the file is named. The standard Java/Groovy naming conventions dictate that classes should begin with a capital letter.

In that, when i created an object it shows error.

def Abc obj = new Abc

There are a couple of problems with this code:

• define the type as either def or Abc but not both
• you're missing some parentheses

Try this instead:

Abc obj = new Abc()
