image uploading in Grails with 5 lines of code

In your domain class, define


class Something{
byte[] image
}

in your controller, call

def image= {
def something = Something.get( params.id )
byte[] image = something.image
response.outputStream << image
}


Image gets copied to the database. You can then show it by

<img src="${createLink(controller:'something', action:'image', id: something.id)}"/>
