Мое приложение работает на все, кроме вызова для отображения членов разных плат. Я могу получить правильный вывод в db с SQL-запросом, но у вас проблемы с его использованием в Grails, используя createCriteria.grails multiple table criteria
Необходимо использовать Oracle 11g как моя БД. Grails 2.3.3 как DB, так и Grails являются локальными.
Вот мои домены
class Trustee {
String salutation
String firstName
String middleName
String lastName
static hasMany = [board:Boards, membership:TrusteeMembership]
static constraints = {
salutation nullable: true
firstName nullable: true
middleName nullable: true
lastName nullable: true
}
//map to the existing DB table
static mapping = {
table 'BOT_TRUSTEE'
id column:'TRUSTEE_ID'
salutation column: 'SALUTATION'
firstName column: 'FIRST_NAME'
middleName column: 'MIDDLE_INITIAL'
lastName column: 'LAST_NAME'
version false
}
}
class Boards {
String boardName
static belongsTo = [trustee:Trustee, hospital:Hospitals]
static constraints = {
boardName nullable:true
}
static mapping = {
table name:"BOT_BOARD"
id column:'BOARD_ID'
trustee column:'TRUSTEE_ID'
hospital column:'HOSPITAL_ID'
boardName column:'BOARD'
version false
}
}
class Hospitals {
String hospitalName
static hasMany = [committees:Committees, board:Boards]
static constraints = {
hospitalName nullable:true
}
static mapping = {
table 'BOT_HOSPITAL'
id column:'HOSPITAL_ID'
hospitalName column:'HOSPITAL'
version false
}
}
class Committees {
String committeeName
String description
static belongsTo = [hospital: Hospitals]
static hasMany = [membership:TrusteeMembership]
static constraints = {
committeeName nullable:true
description nullable:true
}
static mapping = {
table 'BOT_COMMITTEE'
id column:'COMMITTEE_ID'
hospital column:'HOSPITAL_ID'
committeeName column:'COMMITTEE'
description column:'DESCRIPTION'
version false
}
}
class TrusteeMembership implements Serializable{
String position
String type
static belongsTo = [trustee:Trustee, committees:Committees]//
static constraints = {
position nullable:true
type nullable:true
}
static mapping = {
table 'BOT_TRUSTEE_COMMITTEES'
version false
id composite: ['trustee','committees']
trustee column:'TRUSTEE_ID'
committees column: 'COMMITTEE_ID'
position column:'POSITION'
type column:'TYPE'
}
Вот мой контроллер
def members(){
def letter = params.letter
def commId = params.committee
params.max = Math.min(params.max ? params.int('max'): 15, 100)
def indexSearch = Trustee.createCriteria().list(params){
//search by First letter of lastName
if(letter != null){
ilike("lastName", "${letter}%")
}
//search by lastName
if(params.lastName){
ilike("lastName", "%${params.lastName}%")
}
//search by firstName
if(params.firstName){
ilike("firstName", "%${params.firstName}%")
}
//search by boardName
if(params.boardId){
//display only members within a board id
board{
eq("id", "%${params.boardId}%")
}
}
order("lastName", "asc")
}
respond Hospitals.list(params), model:[hospitalsInstanceCount: Hospitals.count(),
trusteeInstanceList : indexSearch]
}
