问题 I'm trying to persist a list of joda LocalDate in grails. What I have right now is something like this: package com.publidirecta import org.joda.time.LocalDate class Evento { List <LocalDate> fechas = [] static hasMany = [fechas:LocalDate] } and I get the following error : MappingException: Missing type or column for column[fechas_persistent_local_date] on domain[Evento] referencing[org.jadira.usertype.dateandtime.joda.PersistentLocalDate] ->> 334 | innerRun in java.util.concurrent.FutureTask

问题 I have a class like class Account { BigDecimal balance = 0 SortedSet transactions AccountOwner owner static constraints = { } static hasMany = [transactions:Transaction] } when I try to query the Account like def account = Account.findByOwner(user) I get this error | Failure: testSave(br.com.fisgo.financial.AccountControllerTests) | org.springframework.dao.InvalidDataAccessResourceUsageException: Cannot query [br.com.fisgo.financial.Account] on non-existent property: owner at org.grails

问题 A Grails 2.3.4 application is connecting to an Oracle database using the following domain class: class Person { String name static mapping = { id column: "PERSON_ID", generator: "sequence", params: [sequence: 'person_seq'] } } The PersonController makes a call to a method in PersonService and it makes a call to UtilService . The method in UtilService being called has some logic based on wether this Person object is new: if (personInstance.id == null) { ... } What I have found is that the id

问题 I have two domain classes: User and Book. class Book implements Serializable{ String bookName Timestamp createdDateTime Blob file static belongsTo = [User] static hasMany = [user :User] } I am able to add user in book using addToUser() method. But I am stuck in create criteria while applying filter in user. def query = Book.createCriteria(); def results = query.list () { eq("user",userObject) // not working since user field is a list of users. order("createdDateTime", "desc") } Please help me

问题 Permanently I have some tables and some hibernate classes with mapping annotations. And this classes have abstract superclass with mapping annotations also. But in this superclass there is no table association mapping. All tables are identified in the subclasses. I'm trying to migrate this mapping to GORM model. But all strategies: TablePerHierarchy and TablePerSubclass not approach for my case because all tables is created and can't be changed. I created superclass in the 'src/groovy

问题 Below is my Pgtyp.groovy (domain class): package marchmock2 class Pgtyp { Date date_hour String mv String pagetype Integer visits Integer visits_ly Integer visits_lw String time_period String platform String device String browser static mapping = { table "pgtyp" version false date_hour column: "date_hour" mv column: "mv" pagetype column: "pagetype" visits column: "visits" visits_ly column:"visits_ly" visits_lw column:"visits_lw" time_period column:"time_period" platform column:"platform"

问题 Setup: Grails 2.5.6 with Hibernate 4.3.10 I have a table with a string id. Thing is, its values are numeric strings, and this seems to mess up get() when I pass in a value such as "000000" . Domain class: class Term { static mapping = { id name: 'code', generator: 'assigned' version false code column: 'CODE' description column: 'DESC' } String code String description } Data looks like: CODE || DESC -------++--------------------------- 000000 || The Beginning of Time 201715 || Post Secondary

问题 I am using Grails 3.0.6 and am struggling with a complicated and highly interconnected domain model. I have classes with multiple many-to-many associations to other classes and I am left with no choice but to have multiple belongsTo associations on at least one class. I am unable to figure out the syntax to represent this. My domain model was quite complicated, but I was able to reduce my problem to this simplified example: class Graph { static hasMany = [vertices: Vertex] } class OtherClass
