I just started learning Grails and I’m trying to play around with the database using the grails console, but I notice that there’s a difference between running grails console and running grails, then console:
When launching grails console straight from Terminal:
~/Desktop/Grails-lab/racetrack $ grails console
| Compiling 1 source files.....
In the console:
groovy> import racetrack.*
groovy> def z = new User(userName:"bangkuangwang",fullName:"noge noge",website:"noge.com",email:"email@email.com",bio:"hello world",password:"123123")
groovy> z.save()
groovy> println(z.errors)
groovy> User.count
grails.validation.ValidationErrors: 0 errors
Result: 1
When launching using grails, then console:
~/Desktop/Grails-lab/racetrack $ grails
| Enter a script name to run. Use TAB for completion:
grails> console
| Compiling 1 source files.....
In the console:
groovy> import racetrack.*
groovy> def z = new User(userName:"bangkuangwang",fullName:"noge noge",website:"noge.com",email:"email@email.com",bio:"hello world",password:"123123")
groovy> z.save()
groovy> println(z.errors)
groovy> User.count
Exception thrown
groovy.lang.MissingMethodException: No signature of method: racetrack.User.save() is applicable for argument types: () values: []

Can anyone explain to me why are the 2 methods of launching grails console behave differently?
Looks like a bug.
I would recommend you stick to “grails console”.
