Having issues with BootStrap.groovy loading development data. Prior it had always loaded data, but now has stopped throwing the below error when running grails run-app.
Message: Validation Error(s) occurred during save():
- Field error in object 'spotlight.content.Profile' on field 'portfolio': rejected value [null];
My 2 models are as follows;
class Portfolio {
Profile profile
String portfolioName
String portdescrip
Integer portpublished
Date dateCreated
Date lastUpdated
AND
class Profile {
static belongsTo = [portfolio: Portfolio]
String portfoliohtml
String portfolioEmail
String portfoliocc
String portfolioAdmin
String portfolioFilestore
String portfolioColor
String bugzillaproduct
String bugzillacomponent
String rtqueue
String teamqueueemail
String etherpadurl
Integer siteupload
Date dateCreated
Date lastUpdated
Within the BootStrap.groovy file I have the following;
import java.util.Date;
import spotlight.content.Profile
import spotlight.content.Portfolio
class BootStrap {
def init = { servletContext ->
def profile = new Profile(portfoliohtml:"No",
portfolioEmail: "ian#ian.com",
portfolioAdmin:"Ian Neilsen",
bugzillaproduct:"bz prod name",
bugzillacomponent:"comp name",
siteupload:1,
portfoliocc: "ian#ian.com",
portfolioColor:"red",
portfolioFilestore:"blah",
rtqueue:"queue name",
teamqueueemail:"ian#ian.com",
etherpadurl:"http://url.com",
).save(failOnError: true)
def portfolio = new Portfolio(portfolioName:"Portfolio 1",
portdescrip:"portfolio descrition field",
portpublished:1,
portfolio:profile).save(failOnError: true)
}
I have tried every incarnation of adding my profile object to the portfolio object without any luck. As I said previously this worked and has now stopped throwing the null error.
has got me stumped any ideas?
cheers
It looks like you have several mistakes.
One (but not causing the error message) is, that you try to add your profile instance to portfolio property of your portfolia instance. Portfolio has no property portfolio.
Regarding your errormessage, try following:
def portfolio = new Portfolio(portfolioName:"Portfolio 1", ...)
portfolio.profile = new Profile(...)
portfolio.save(failOnError: true)
For further reading, look at the Many-to-one and one-to-one (GORM) section of the grails docs.

Good day to all. I am very new in using grails and I have followed several tutorials for beginners using grails until I come up in creating domain relationships. However, I got stuck with this problem right now. I have 3 domain classes namely, todo, category and user. And as I defined their relationships, it returns me an error saying unable to resolve class. Please see my codes below. Please help. Thank you so much.
Todo.groovy Class
package todoScaff
class Todo {
String name
String note
Date createDate
Date dueDate
Date completedDate
String priority
String status
User owner
Category category
static belongsTo = [User, Category]
static constraints = {
name(blank:false)
createDate()
priority()
status()
note(maxsize:1000, nullable:true)
completedDate(nullable:true)
dueDate(nullable:true)
}
String toString() {
name
}
}
Category.groovy Class
package categoryScaff
class Category {
String name
String description
User user
static belongsTo = User
static hasMany = [todos: Todo]
static constraints = {
name(blank:false)
}
String toString(){
name
}
}
User.groovy Class
package userScaff
class User {
String userName
String fname
String lname
static hasMany = [todos: Todo, categories: Category]
static constraints = {
userName(blank:false, unique:true)
fname(blank:false)
lname(blank:false)
}
String toString(){
"$lname, $fname"
}
}
Since you've placed your domain classes in different packages, you must import the classes at the head of the file.
package categoryScaff
import todoScaff.Todo
import userScaff.User
class Category {
The same needs to happen in your other domain classes that reference classes outside the current package.
I'm new to Grails. I'm developing a web app that handles the records of a gymnasium, to make routines, exercises, etc.
I have this domain class Ejercicios:
class Ejercicios {
String nombreEjercicio
String idHoja
String descripcion
List<String> descripcionO
static hasMany = [descripcionO: Descripciones]
static transients = ['descripcionTrans']
String descripcionTrans
static mapping = {
id column: "idHoja"
version false
}
static constraints = {
nombreEjercicio maxSize: 45
idHoja blank: false
}
The database table has the default Grails id named "idHoja", and another attribute named "id_hoja"
The thing here is that when I make a JSON parse from the rest API, I need GORM to look for exercises via the "id_hoja" attribute, not the "idHoja" because it'll cause a mismatch.
I found the solution by myself!
The only thing I needed to was to make the JSON call with the name "idHoja" and that was it.
I'm using MongoDB exclusively with a Grails REST app and the domain shown below. This respond call fails:
#Secured(['permitAll'])
def index() {
respond Person.list()
}
with the error
ERROR errors.GrailsExceptionResolver - IllegalAccessException occurred when processing request: [GET] /teesheet/person
Class org.codehaus.groovy.grails.web.converters.marshaller.json.GroovyBeanMarshaller can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public". Stacktrace follows:
Message: Class org.codehaus.groovy.grails.web.converters.marshaller.json.GroovyBeanMarshaller can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public"
Attempting to convert the collection to JSON also fails with the same error.
def personList = Person.list() as JSON
The low level API works.
package com.tworks.teesheet
import grails.rest.Resource
class Person {
String name
String firstName
String lastName
String email
User userPerson
TimeZone timeZone = TimeZone.getTimeZone("America/Los_Angeles")
Date dateCreated = new Date()
Date dateModified = new Date()
}
Assuming you're using Mongo for Grails plugin, you need #Entity for domain classes...
import grails.persistence.Entity
#Entity
class Person {
static mapWith = "mongo"
String name
String firstName
String lastName
String email
}
I added mapWith="mongo" since I wasn't sure if you're using the hibernate plugin alongside the mongo plugin; if you're not, remove hibernate, otherwise, it may interfere.
I'm currently using the low level calls to iterate using the cursor but it seems like the respond Person.list() should work. This code is working:
def cursor = Person.collection.find()
def items = []
try {
while (cursor.hasNext()) {
items << com.mongodb.util.JSON.serialize(cursor.next())
}
} finally {
cursor.close()
}
log.info("items: ${items}")
render items
In my grails project, I've used the method Object.findAllByIdInList(), passing a list as parameter.
The code used is the following:
def allSelectedIds = ReceiptItem.findAllByIdInList(par)
In which the ReceiptItem is a domain class defined as follows:
class Receipt {
double totalAmount;
Date releaseDate;
int vatPercentage;
int discount;
Boolean isPayed;
Boolean isInvoice;
static belongsTo = [patient:Patient]
static hasMany = [receiptItems:ReceiptItem]
static constraints = {
receiptItems(blank: false)
patient(blank: false)
totalAmount(blank: false)
vatPercentage(blank: false, nullable: false)
}
}
and par is the list of ids defined as follows:
def par = params.list("receiptItemsSelected")
receiptItemsSelected is defined in the gsp page into the remoteFunction() as follows:
params: '\'receiptItemsSelected=\' + jQuery(this).val()'
The problem is that the line above throws the following exception:
java.lang.String cannot be cast to java.lang.Long. Stacktrace follows:
Message: java.lang.String cannot be cast to java.lang.Long
I don't understand why it is throwing this exception.
Thanks for your help
Probably list par has ids as String. Generally id for domain objects is stored as Long. Try this instead
ReceiptItem.findAllByIdInList(par*.toLong())
*Also make sure that id represented as string isNumber().
assert !'C'.isNumber()
assert '4'.isNumber()
I'm new to Grails and study it via InfoQ's "Getting Started With Grails" book.
Running through it I've faced a problem with the BootStrap.groovy file:
I've edited it as the book says.
Run-app it - and the data I've entered into BootStrap.groovy has been shown.
I've updated the bootstrapping values but they are not changed.
No errors are shown in the console.
What I've tried:
exchanging def's places;
set Runner's class value to nullables;
changed .save(failOnError:true) to .save(flush:true).
Even after I've changed the Race class' bootstrapping values it looks like it hasn't been changed.
Looks like the value is taken from somewhere else than the BootStrap.groovy?
I use Grails 2.2.1 with a PostgreSQL DB.
The classes' code is below:
package racetrack
class Runner {
static constraints = {
firstName(blank:false)
lastName(blank:false)
dateOfBirth(nullable:true)
gender(inList:["M","F"])
address(nullable:true)
city(nullable:true)
state(nullable:true)
zipcode(nullable:true)
email(email:true)
}
static hasMany = [registrations:Registration]
/*static mapping = {
sort "email"
}*/
String firstName
String lastName
Date dateOfBirth
String gender
String address
String city
String state
String zipcode
String email
String toString(){
"${firstName} ${lastName} (${email})"
}
}
and
package racetrack
class BootStrap {
def init = { servletContext ->
def begun = new Runner(firstName:"Marathon",
lastName:"Runner",
dateOfBirth:"",
gender:"M",
address:"",
city:"",
state:"",
zipcode:"",
email:"me#me.ru"
)
begun.save(flush:true)
def zabeg = new Race(name:"Run SPB",
startDate:new Date() + 360*30,
city:"Moscow",
state:"Moscow",
cost:10.0,
distance:42.0,
maxRunners:10)
zabeg.save(flush:true)
}
def destroy = {
}
}
EDIT: could this be happening due to any generate-* scripts been run?
Race.groovy:
package racetrack
class Race {
static hasMany = [registrations:Registration]
String name
Date startDate
String city
String state
BigDecimal distance
BigDecimal cost
Integer maxRunners
static constraints = {
name(blank:false, maxSize:50)
startDate(validator: {
return (it >= new Date())
}
)
city()
state(inList:["Moscow", "Volgograd", "SPb", "NN"])
distance(min:0.0)
cost(min:0.0, max:100.0)
maxRunners(min:0, max:100000)
}
static mapping = {
sort "startDate"
}
BigDecimal inMiles(){
return distance*0.6214
}
String toString(){
return "${name}, ${startDate.format('MM/dd/yyyy')}"
}
}
BootStrap should be in grails-app/conf instead. Refer this.
Try to print the errors of the new instance you save by adding
print begun.errors
See if somethings comes up.
You need to remove
def index() { }
from the controllers.
I had the same issue. Now it is fixed.
