Displaying Grails Field Errors

Question

Does anybody know how I could get the fieldError to print out in the example below.

for each item with an error, I would like to print custom error messages that I have defined in the messages.properties file

at the moment all this does is print the default error codes

item.errors?.allErrors?.each{ 
println it.toString() 
};

I have seen other examples where you can lookup an error code for a field e.g.

it.getFieldError('title').code

but I would like to convert the default message into my new error message and print that

thanks for your help

You need access to the messageSource bean, e.g. with

def messageSource

in your controller or service. Then you can access the messages with

def locale = Locale.getDefault()
for (fieldErrors in bean.errors) {
   for (error in fieldErrors.allErrors) {
      String message = messageSource.getMessage(error, locale)
   }
}
