I have the following domain class:
class User {
String name
String contactName
String primaryEmail
String url
String phoneNumber
String address
static hasMany = [users: User]
static constraints = {
name blank: false
contactName blank: false
primaryEmail email: true
url blank: false
phoneNumber blank: false
address blank: false
}
}
And controller for the User:
class UserController {
def create() {
User user = new User()
[user: user]
}
def save(User user) {
if (!user.save(flush: true)) {
render (view : 'create', model: [user: user])
}
redirect action: 'create'
}
}
I want show validation errors in case if validation fails. My create.gsp looks like this:
<body>
<g:form action="save" >
<g:renderErrors bean="${user}"/>
<g:textField name="user.name" id="message" value="${user.name}"/>
<g:textField name="user.contactName" id="contactName" value="${user.contactName}"/>
<g:textField name="user.primaryEmail" id="primaryEmail" value="${user.primaryEmail}"/>
<g:textField name="user.url" id="url" value="${user.url}"/>
<g:textField name="user.phoneNumber" id="phoneNumber" value="${user.phoneNumber}"/>
<g:textField name="user.address" id="address" value="${user.address}"/>
<g:submitButton name="submit" value="Save"/>
</g:form>
</body>
</html>
But after sumbit of create.gsp with invalid data two strange thing happen 1) Despite the fact that all fields have value property mapped to some field of User bean all fields are empty
2) There are no validation errors on the page What I'm doing wrong? Thank you!
you must return after calling render() or use else
def save(User user) {
if (!user.save(flush: true)) {
render (view : 'create', model: [user: user])
return // either return here
}else // or else here
redirect action: 'create'
}
In your original code you redirect to create and pass no models into it
