I am new to Grails . I am using Grails 3.0.17 in my project . I have created a dummy project named A I have created a dummy class B in my domain as below:-
class B {
String name
static constraints = {
}
}
I have auto generated the controller for these
I have auto generated the views for this domain Controller looks like this:-
package a
import static org.springframework.http.HttpStatus.*
import grails.transaction.Transactional
@Transactional(readOnly = true)
class BController {
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
def index(Integer max) {
params.max = Math.min(max ?: 10, 100)
respond B.list(params), model:[bCount: B.count()]
}
def show(B b) {
respond b
}
def create() {
respond new B(params)
}
@Transactional
def save(B b) {
if (b == null) {
transactionStatus.setRollbackOnly()
notFound()
return
}
if (b.hasErrors()) {
transactionStatus.setRollbackOnly()
respond b.errors, view:'create'
return
}
b.save flush:true
request.withFormat {
form multipartForm {
flash.message = message(code: 'default.created.message', args: [message(code: 'b.label', default: 'B'), b.id])
redirect b
}
'*' { respond b, [status: CREATED] }
}
}
def edit(B b) {
respond b
}
@Transactional
def update(B b) {
if (b == null) {
transactionStatus.setRollbackOnly()
notFound()
return
}
if (b.hasErrors()) {
transactionStatus.setRollbackOnly()
respond b.errors, view:'edit'
return
}
b.save flush:true
request.withFormat {
form multipartForm {
flash.message = message(code: 'default.updated.message', args: [message(code: 'b.label', default: 'B'), b.id])
redirect b
}
'*'{ respond b, [status: OK] }
}
}
@Transactional
def delete(B b) {
if (b == null) {
transactionStatus.setRollbackOnly()
notFound()
return
}
b.delete flush:true
request.withFormat {
form multipartForm {
flash.message = message(code: 'default.deleted.message', args: [message(code: 'b.label', default: 'B'), b.id])
redirect action:"index", method:"GET"
}
'*'{ render status: NO_CONTENT }
}
}
protected void notFound() {
request.withFormat {
form multipartForm {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'b.label', default: 'B'), params.id])
redirect action: "index", method: "GET"
}
'*'{ render status: NOT_FOUND }
}
}
}
But when i run localhost:8080 i am not able to see the fields name ,

As you can see i am not able to see the name fields there in create page nor in index page.
