grails-validation

I'm using grails 2.2.1 and attempting to validate a nested command structure. Here is a simplified version of my command objects: @Validateable class SurveyCommand { SectionCommand useful SectionCommand recommend SurveyCommand() { useful = new SectionCommand( question: 'Did you find this useful?', isRequired: true) recommend = new SectionCommand( question: 'Would you recommend to someone else?', isRequired: false) } } @Validateable class SectionCommand { String question String answer boolean isRequired static constraints = { answer(validator: answerNotBlank, nullable: true) } static

This question comes from the problem of another question of mine. In that question, I come across a situation that hasErrors() function doesn't work for non-persistent domain class , even after all the things I did following the instruction , part 7.5 . Following Victor's way, I fixed the problem by calling validate(), but I don't understand why it works. The Grails documents seem to say nothing about you should call a validate() before hasErrors() function. How could this happen? It does make sense to me that validate would need to be called before asking an object whether it hasErrors (or

I have a restriction so there could be no more than ConfigurationHolder.config.support.reminder.web.person.max object stored. I didn't find how to add a validator which doesn't relate on particular property. So for now I implemented it in this way. Do you guys have any ideas how to make it better? package support.reminder.web import org.codehaus.groovy.grails.commons.ConfigurationHolder; class Person { String firstName String lastName String email Date lastDutyDate static constraints = { firstName(blank: false) lastName(blank: false) email(blank: false, email: true) lastDutyDate(nullable: true

I have a form to create a place. Depending of the country, the province (state, region) field is required or not. When is not required, I want to be null, not empty string. I have code that makes all empty form fields, null: def newparams = [:] place = new Place() params.each() { k, v -> if (v instanceof String && place.hasProperty(k)) { if (!v.trim().length()) { newparams[k] = null } else { newparams[k] = v } } } place = new Place(newparams) place.validate() Now, in the place domain, I have a validator on the province: province validator: {val, obj -> if (obj.country in obj

How do you (if you) manage client side validation with grails ? Do you use a plugin or do you mirror your constraints using a javascript framework ? Cheers leebutts I haven't used them personally but these two plugins might help you out: http://grails.org/plugin/javascript-validator http://www.grails.org/plugin/remote-constraints On Grails projects that I've been a part of, We haven't used a plugin but rather a mashup of javascript plugins and custom validators (jQuery plugins, Prototype, Dojo, etc.) to achieve the client side validation. Its handy to provide instant field-level validation on

I have a Person object with a lastName field. The lastName field cannot be blank. When the user submits a form blank value in the lastName field, the error message that the user sees is: Property [lastName] of class [com.example.Person] cannot be blank This error message is lame. I want to customize it to something more user friendly, like "The Last Name field cannot be blank" How do I do that? See Chapter 7 of the docs: http://grails.org/doc/latest/ You would change grails-app/i18n/messages.properties and add person.lastName.blank=The Last Name field cannot be blank In Grails 3 you need to

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