Comment on Build a Custom Validator in Grails with a Plugin by Geoff Lane

@aditi,
From what you are doing, it sounds like you should implement it as a persistent constraint. A persistent constraint would let you query the database for the previous bid for a given item and then compare that to the new bid. Take a look at the “UniqueEgConstraint” example on GitHub for an example of how to write a persistent constraint.

I need to add a validator where bid amount should always be $.50 greater than previous bid. Do i need to declare two variables (bid and old bid) in my domain class to do this?

Will it work for passwords on other languages then English? I expect some problems with the upper and lower case rules.

In my opinion regular expressions is a two powerful tool for this task. A simple single loop would be enough.

well the thing is that i dont even have anything in the ast transformation class… but as soon as i just add the annoation

@GroovyASTTransformationClass({ “com..util.ast.AddDateASTTransformation” })

it brings me the error… seems like there maybe an issue with groovy or something…

maybe you have any tricks how to reset the groovy compilation? or do you maybe have an example project that i could try?

this is what my annotation looks like:

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

import org.codehaus.groovy.transform.GroovyASTTransformationClass;

@Target({ ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@GroovyASTTransformationClass({ “com.util.ast.AddDateASTTransformation” })
public @interface AddDate {
}

thanks for any help

Chris

@Chris,
AST Transformations are really hard to debug since they’re done at compile time. I’ve seen that issue myself when I didn’t have things quite right. I’d try using some println statements and catching runtime exceptions (and then printing out the results) to figure out what’s happening. Other than that, it’s a bit hard to say without seeing more code…
