grails 3 spring security User domain id field synthetic - grails

I am using grails 3.2.9 with spring-security-core plugin 3.1.2.
I've run the s2-quickstart script to create User, Role, and UserRole domain classes. I've found that the id field in the User and Role domains is being considered synthetic. For instance, if I run the following bit of code the id field is not shown:
def u = User.class.declaredFields.findAll {!it.synthetic}
u.each {
println it
}
Here is my User class:
#GrailsCompileStatic
#EqualsAndHashCode(includes='username')
#ToString(includes='username', includeNames=true, includePackage=false)
class User extends BaseDomain implements Serializable {
private static final long serialVersionUID = 1
String username
String password
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired
Date lastLogin
Set<Role> getAuthorities() {
(UserRole.findAllByUser(this) as List<UserRole>)*.role as Set<Role>
}
static constraints = {
password blank: false, password: true
username blank: false, unique: true
}
static mapping = {
id generator: 'identity', column: 'user_id', sqlType: 'bigint(20) unsigned'
password column: '`password`'
lastLogin sqlType: 'timestamp'
}
}
This is not happening with my other domain classes, and the first problem I see this causing is with the exa-datatables plugin (2.0.1). The plugin uses similar code to find the fields of a domain, so when requesting the id field to be displayed by the plugin it fails with an unknown column error.

I found this was being caused because I was extending a class (BaseDomain in the example), and I did not mark the BaseDomain as abstract. As soon as I qualified BaseDomain as abstract, everything started working as expected.
abstract class BaseDomain {...

populate a dropdown in grails

i have a user that i give a role to it, and i want when i create the user, to show the roles in a dropdown, then i can select the role that i want to give to him, how can i do it ?? please i really need help in it, cause im new in grails here is the user.groovy
class User {
transient securiteService
String username
String password
String nom
String prenom
String email
String tel
static hasMany = [roles : Role]
static constraints = {
username blank: false, unique: true
password blank: false,display: false
nom nullable: true
prenom nullable: true
email email:true, nullable:true
tel nullable:true, maxSize:20, matches:/[\+]{0,1}[0-9\s]{3,15}/
}
static mapping = {
password column: '`password`'
sort nom: "asc"
affectations sort : "dateAffectation", order:"desc"
intervention sort : "responsable", order:"desc"
}
}
The following example will help you, make necessary changes in your code according to your need.
For example you have a table / domain Role
class Role {
String roleId
String roleName // e.g ROLE_ADMIN
}
// Populate the dropdown in your GSP view ( this will populate all the roles present in the Role table)
<g:select from="${Role.list().roleName}" name="selectUserRole"
              optionKey=""
              optionValue=""/>

How to use beforeInsert() and beforeUpdate() in GORM

I'm working on an inventory management system in Grails, the application will keep track of assets information such as Users, Brand, Type etc. I have 3 domain classes (other class are not important for this discussion) namely, User, Movement and Inventory.
Each assets is owned by a particular User. When the asset is transferred from the current owner to a new owner in the Movement class, the change should be reflected in the User class and Inventory class. These are my classes:
User:
class User {
String userID
String fullName
String position
Department department
String toString(){
fullName
}
static hasMany = [inventories: Inventory, movementsByOldUser: Movement, movementsByNewUser: Movement]
static mappedBy = [movementsByOldUser: 'oldUser', movementsByNewUser: 'newUser']
static constraints = {
userID blank: false, unique: true
fullName blank: false
position()
department()
}
}
Movement:
class Movement {
User oldUser
User newUser
Inventory inventoryID
Date movementDate
User userResponsible
static constraints = {
inventoryID blank: false
oldUser blank: false
newUser blank: false
movementDate()
userResponsible blank: false
}
}
Inventory:
class Inventory {
String inventoryID
String code
String description
String serial_num
Date purchase_date
Date record_date
Type type
Brand brand
User user
static hasMany = [movements: Movement]
String toString(){
"$inventoryID, $type"
}
static constraints = {
inventoryID blank: false, unique: true
code blank: false
description nullable: true, maxSize: 1000
serial_num blank: false
purchase_date()
image nullable: true, maxSize: 1000000
record_date()
remarks nullable: true, maxSize: 1000
type()
brand()
user()
}
}
I have heard of the GORM method called beforeInsert() and beforeUpdate() that they can do the job, but I'm completely new to Grails, Groovy and of course GORM as this is the first application I develop, I have no idea how to use them in my codes. I did host of research but none match my scenario so I cannot get a clear picture of how to use it.
Question edited from here:
I have made some changes to the class User by using beforeUpdate() and beforeUpdate() but it gets an error shown below.
User class (edited version):
class User {
String userID
String fullName
String position
Department department
String toString(){
fullName
}
static hasMany = [inventories: Inventory, movementsByOldUser: Movement, movementsByNewUser: Movement]
static mappedBy = [movementsByOldUser: 'oldUser', movementsByNewUser: 'newUser']
def beforeInsert(){
this.fullName = 'oldUser'
}
def beforeUpdate(){
this.fullName = 'newUser'
}
static constraints = {
userID blank: false, unique: true
fullName blank: false
position()
department()
}
}

Relationships between Grails domain classes with inheritance

I have the following class. In src/groovy,
class Profile {
String firstName
String middleName
String lastName
byte[] photo
String bio
}
The domain classes BasicProfile and AcademicProfile extend Profile.
class BasicProfile extends Profile {
User user
Date dateCreated
Date lastUpdated
static constraints = {
firstName blank: false
middleName nullable: true
lastName blank: false
photo nullable: true, maxSize: 2 * 1024**2
bio nullable: true, maxSize: 500
}
static mapping = {
tablePerSubclass true
}
}
class AcademicProfile extends Profile {
User user
String dblpId
String scholarId
String website
Date dateCreated
Date lastUpdated
static hasMany = [publications: Publication]
static constraints = {
importFrom BasicProfile
dblpId nullable: true
scholarId nullable: true
website nullable: true, url: true
publications nullable: true
}
static mapping = {
tablePerSubclass true
}
}
Then there is a Publication class.
class Publication {
String dblpId
String scholarId
String title
String description
Date publicationDate
int citations
Date dateCreated
Date lastUpdated
static belongsTo = [AcademicProfile]
static hasOne = [publisher: Publisher]
static hasMany = [academicProfiles: AcademicProfile]
static constraints = {
dblpId nullable: true
scholarId nullable: true
title blank: false, maxSize: 100
description nullable: true, maxSize: 500
publicationDate: nullable: true
academicProfiles nullable: false
}
}
Finally, I have a User class.
class User {
String username
String password
String email
Date dateCreated
Date lastUpdated
static hasOne = [basicProfile: BasicProfile, academicProfile: AcademicProfile]
static constraints = {
username size: 3..20, unique: true, nullable: false, validator: { _username ->
_username.toLowerCase() == _username
}
password size: 6..100, nullable: false, validator: { _password, user ->
_password != user.username
}
email email: true, blank: false
basicProfile nullable: true
academicProfile nullable: true
}
}
My questions are as follows.
I want a relationship where each User may optionally have a Profile (either BasicProfile or AcademicProfile). I tried static hasOne = [profile: Profile] but I got errors saying Profile does not agree to the hasOne relationship. So the current setup I have is a workaround. Is there no way a user can have one Profile be it BasicProfile or AcademicProfile?
Secondly, in the current setup, I get the error: Invocation of init method failed; nested exception is org.hibernate.MappingException: An association from the table academic_profile_publications refers to an unmapped class: org.academic.AcademicProfile when I try to run it. A Google search tells me that this is a problem with classes which are inheriting from other classes. So technically, if I don't have a hasMany relationship in Publication with AcademicProfile, it should work without any issues. But I don't want that. Because a publication has many authors (AcademicProfiles in my case) and an author may have many publications. So is there a way to fix this?
You're not using Hibernate inheritance - that requires that all of the classes be mapped. You're just using regular Java/Groovy inheritance where you inherit properties and methods from base classes. But Hibernate isn't aware of that, so it can't do queries on the unmapped base class.
I'm not sure why it's complaining about AcademicProfile, but it could be a secondary bug caused by the core issue.
I find Hibernate inheritance to be way too frustrating to use in most cases, so I use this approach when there is shared code.
It should work if you move Profile to grails-app/domain. Once you do that you should move the tablePerSubclass mapping config to the base class and only specify it once.

springSecurityService how to NOT store passwords in cleartext?

This tutorial:
http://spring.io/blog/2010/08/11/simplified-spring-security-with-grails/
Says you should create users like this:
def adminUser = SecUser.findByUsername('admin') ?: new SecUser(
username: 'admin',
password: springSecurityService.encodePassword('admin'),
enabled: true).save(failOnError: true)
However, this does not work. It only works if you do this:
password: 'admin'
Which I am assuming (but could be wrong) that stores the password in the internal DB in plain text (not hashed).
Is there a way to tell spring to encrypt or hash passwords? Its not in any of the tutorials, and can't find it in the manual
Grails 2.3.6, security core 2.0-RC2 & UI, default install.
I have seen it said that grails by default does hash with bcrypt, but I dont know how to verify this. I guess I need to install mysql, tell grails to use this, then I can query the values.
Take a deep breath. By default the spring security plugin for Grails (recent versions) isn't going to store you passwords in clear text.
Take a look at your SecUser domain class and you will see that it's handling the encryption of the password for you. You can also see an example of this in the documentation.
This is directly from the documentation.
package com.mycompany.myapp
class User {
transient springSecurityService
String username
String password
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static transients = ['springSecurityService']
static constraints = {
username blank: false, unique: true
password blank: false
}
static mapping = {
password column: '`password`'
}
Set<Role> getAuthorities() {
UserRole.findAllByUser(this).collect { it.role } as Set
}
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService.encodePassword(password)
}
}
If you haven't already read through the documentation I suggest you do. It's well written and will likely answer a lot of other questions you have about the plugin.

Grails domain class constraint modification causing exception

Am using grails 2.0.3 with default h2 database and have the following user domain class:
class User {
transient springSecurityService
String username
String password
boolean enabled
boolean accountExpired
boolean accountLocked
boolean passwordExpired
Preferences preferences
Company company
Personal personal
static constraints = {
username email: true, blank: false, unique: true
password blank: false
preferences unique: true
company unique: true
personal unique: true
}
static mapping = {
password column: '`password`'
}
Set<Role> getAuthorities() {
UserRole.findAllByUser(this).collect { it.role } as Set
}
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService.encodePassword(password)
}
}
In the controller, I save the user using the following code:
userInstance.save(flush: true)
Now, this afternoon, I realized that the password field should have a size constraint and hence modified the domain class so that it became as follows (only change is in the constraints):
class User {
transient springSecurityService
String username
String password
boolean enabled
boolean accountExpired
boolean accountLocked
boolean passwordExpired
Preferences preferences
Company company
Personal personal
static constraints = {
username email: true, blank: false, unique: true
password blank: false, size: 6..15
preferences unique: true
company unique: true
personal unique: true
}
static mapping = {
password column: '`password`'
}
Set<Role> getAuthorities() {
UserRole.findAllByUser(this).collect { it.role } as Set
}
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService.encodePassword(password)
}
}
Subsequently I generated the views and controllers again. Now when I am trying to save the user object from the controller, using:
userInstance.save(flush: true)
I am getting the following exception:
Class: org.hibernate.AssertionFailure
Message: null id in login.User entry (don't flush the Session after an exception occurs)
Any help will be appreciated.
Info: If I remove the size constraint from the new/modified class the
saving happens fine.
I ran into the same problem using Grails 3.1.12. This is what I found out and how I solved it.
Problem:
You are trying to put a size constraint to a field that is going to be enconded. This means that a password like "admin5" will turn at the end of the domain life cycle as an encoded pwd. For example the db will stored the pwd as: "$2a$10$dn7MyN.nsU8l05fMkL/rfek/d1odko9H4QUpiNp8USGhqx9g0R6om".
The validation process will apply the size constraint to the unencoded pwd (validation step on the domain life cycle), wich will pass because the pwd typed by the user is in that range. but on the save() method (persistance step on the domain life cycle) the pwd will be encoded before an insert or update. The enconding method will create a pwd with a size bigger than your constraint and Hibernate will fail the assert() for the pwd size.
Solution:
Use the minSize constraint if you don't need to worry about the maxSize
static constraints = {
password blank: false, minSize:6
}
If you need to validate the maxSize, then I recommend you do the validation on your Service or Controller layer before creating the domain instance.
