To insert a row to the contact table, your code will look like this:
def manualAdd(){
for (int i; i<5; i++){
Contact p = new Contact(
firstName:'First name '+i,
lastName:'Last Name '+i,
email:'email'+i+'@gmail.com',
city:'City '+i,
country:'Country '+i,
message:'message '+i
).save()
}
render "Added 5 data "
}
