  • Grails query not using GORM

    - by Tihom
    What is the best way to query for something without using GORM in grails? I have query that doesn't seem to fit in the GORM model, the query has a subquery and a computed field. I posted on stackoverflow already with no response so I decided to take a different approach. I want to query for something not using GORM within a grails application. Is there an easy way to get the connection and go through the result set?

  • Use of GORM methods in Integration test

    - by canotto90
    I'm trying to use gorm find method on my domain class, inside of an Spock Integration Spec. My code: class myDomainClassSpec extends IntegrationSpec{ ... def 'my test'() { when: ... then: MyDomainClass.find { id == 1 } } ... } This fails, throwing: groovy.lang.MissingPropertyException: No such property: id for class: grails.gorm.DetachedCriteria If instead I code: MyDomainClass.findAll().find { id == 1 } it works. Any ideas??

  • How much of Grails GORM to test?

    - by Lloyd Meinholz
    Is there a "best practice" or defacto standard with how much of the GORM functionality one should test in the unit/functional tests? My take is that one should probably do most of the domain testing as functional tests so that you get the full grails environment. But what do you test? Inserts, updates, deletes? Do you test constraints even though they were probably more thoroughly tested by the grails release? Or do you just assume that GORM does what it is supposed to do and move to other parts of the application?

  • accessing associations within GORM Events

    - by Don
    Hi, My Grails app has a User class and a Role class. The User class has an authorities property which holds the roles assigned to that user, e.g. class User { static hasMany = [authorities: Role] // This method is called automatically after a user is inserted def afterInsert() { this.authorities.size() } } If I create a user and assign them a role, a NullPointerException is thrown from the GORM event method afterInsert(), because authorities is null. If I comment out afterInsert() the user is saved correctly along with the assigned role. Is there some reason why I can't access associations from GORM event methods. Is is possible that this event is fired after the User row is inserted, but before the row is added to the User-Role join table? Thanks, Don

  • GORM column names for simple one to many mapping

    - by Toby Hobson
    I have this setup class User { Date lastLogin // logins is a history of logins static hasMany = [logins : Date] def setLastLogin(Date date) { if (date) { lastLogin = date addToLogins(date) } } } GORM is generating a table MEMBER_LOGINS which currently looks like this: USER_ID, LOGINS Instead I would like USER_ID, DATE I tried adding a mapping in User static mapping = { logins column: 'date'; } But that just changed the foreign key so i now have DATE, LOGINS How can I change the LOGINS column? Thanks!

  • GORM "getNextException" equivalent

    - by Josh K
    GORM sits on top of [Hibernate](http://en.wikipedia.org/wiki/Hibernate_(Java). The issue is that sometimes Hibernate will throw exceptions from the JDBC driver that I can't figure out how to investigate. Specifically: Could not execute JDBC batch update; /* snip */ Caused by: java.sql.BatchUpdateException: /* snip */ [insert] was aborted. Call getNextException to see the cause. If it makes any difference I'm using PostgreSQL.

  • Quering computed fields in GORM

    - by Tihom
    I am trying to query the following HQL using GORM: MailMessage.executeQuery("toId, count(toId) from (SELECT toId, threadId FROM MailMessage as m WHERE receiveStatus = '$u' GROUP BY threadId, toId) as x group by x.toId") The problem is that count(toId) is a computed field doesn't exist in MailMessage and that I am using a subquery. I get the following error: java.lang.IllegalArgumentException: node to traverse cannot be null! Ideally, I would like to use a generic executeQuery which will return data of anytype. Is there such a thing?

  • Grails GORM (Hibernate) query

    - by bsreekanth
    Hello, I'm trying to do the below sql statement in GORM select * from table1 where table1.x not in (select x from table 2 where y='something'); so, I have two tables, and needs to find the entries from table 1 which are not in table 2. In Grails def xx= table2.findByY('something') def c = table1.createCriteria() def result= c.list { not ( in('x', xx) ) } the syntax is wrong, and I'm not sure how to simulate not in sql logic. As a learning point, if someone can also tell me why minus (-) operator in grails/groovy doesn't work with list. I tried getting x and y seperately, and doing x.minus(y), but it doesn't change the list. I saw an explanation at http://stackoverflow.com/questions/1754576/groovy-on-grails-list-not-working , but I would expect the list defined are local. thank you so much.

  • Efficiently retrieve objects with one to many references in Grails using GORM

    - by bebeastie
    I'm trying to determine how to find/retrieve/load objects efficiently in terms of a.) minimizing calls to database and b.) keeping the code as elegant/simple as possible (i.e. not writing hql etc.). Assume you have two objects: public class Foo { Bar bar String badge } public class Bar { String name } Each Foo has a bar and a badge. Also assume that all badges are unique within a bar. So if a Foo has a badge "4565" there are no other Foos that have the same badge # AND the same bar. If I have a bar ID, how can I efficiently retrive the Foo w/o first selecting Bar? I know I can do this: Foo.findByBadgeAndBar("4565", Bar.findById("1")) But that seems to cause a select on the Bar table followed by a select on the Foo table. In other words, I need to produce the Grails/Hibernate/GORM equivalent of the following: select * from foo where badge="4565" and bar_id="1"

  • Grails / GORM, read-only cache and transient fields

    - by Stephen Swensen
    Suppose I have the following Domain object mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject instances seem to be shared due to the caching, and thus transient fields are writing over each other. For example, def r1 = DomainObject.get(1) r1.userId = 22 def r2 = DomainObject.get(1) r2.userId = 34 assert r1.userId == 34 That is, r1 and r2 are references to the same instance. This is undesirable, I would like to cache the table data without sharing references. Any ideas?

  • Groovy on Grails: GORM and BitSets?

    - by Visionary Software Solutions
    I don't see anything in the official documentation about unsupported persistence data types, so I'm working under the assumption that types available in the Groovy language should be handled. However, for the following domain class: class DocGroupPermissions { Workgroup workgroup; Document document; BitSet permissions = new BitSet(2) public DocGroupPermissions() {} void setPermissions(boolean canRead, boolean canWrite){ setReadPermissions(canRead) setWritePermissions(canWrite) } BitSet getPermissions() { return permissions } void setReadPermissions(boolean canRead) { permissions.set(0,canRead) } void setWritePermissions(boolean canWrite) { permissions.set(1,canWrite) } boolean getReadPermissions() { return permissions.get(0) } boolean getWritePermissions() { return permissions.get(1) } static belongsTo = [workgroup:Workgroup, document:Document] static constraints = { workgroup(nullable:false, blank:false) document(nullable:false, blank:false) } } I'm getting: 2009-11-15 16:46:12,298 [main] ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: An association from the table doc_group_permissions refers to an unmapped class: java.util.BitSet Has anyone run into this before?

  • Result set mapping in Grails / GORM

    - by armandino
    I want to map the result of a native SQL query to a simple bean in grails, similar to what the @SqlResultSetMapping annotation does. For example, given a query select x.foo, y.bar, z.baz from //etc... map the result to class FooBarBaz { String foo String bar String baz } Can anyone provide an example of how to do this in grails? Thanks in advance.

  • GORM ID generation and belongsTo association ?

    - by fabien-barbier
    I have two domains : class CodeSetDetail { String id String codeSummaryId static hasMany = [codes:CodeSummary] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_set_detail_id', generator: 'assigned' } } and : class CodeSummary { String id String codeClass String name String accession static belongsTo = [codeSetDetail:CodeSetDetail] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_summary_id', generator: 'assigned' } } I get two tables with columns: code_set_detail: code_set_detail_id code_summary_id and code_summary: code_summary_id code_set_detail_id (should not exist) code_class name accession I would like to link code_set_detail table and code_summary table by 'code_summary_id' (and not by 'code_set_detail_id'). Note : 'code_summary_id' is define as column in code_set_detail table, and define as primary key in code_summary table. To sum-up, I would like define 'code_summary_id' as primary key in code_summary table, and map 'code_summary_id' in code_set_detail table. How to define a primary key in a table, and also map this key to another table ?

  • Grails GORM on multiple Forms

    - by Fabien Barbier
    Usually I'm using One-to-many relationship by this way : class Subject { static hasMany = [ crfs : Crf ] String name ... } class Crf { String title String info ... } I can extend this relationship to others domains, Ex : static hasMany = [ crfs : Crf, crfb : CrfBlood ...] But in my case I have to link the Subject domain to 30 others domains, maybe more...(ex : CrfBlood, CrfMedical, crfFamily, etc...). What domain model implementation should I use in my case ? I would like to keep the dynamic finders usability in my project.

  • Grails / GORM, Disable First-level Cache

    - by Stephen Swensen
    Suppose I have the following Domain class mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject are being shared due to first-level caching, and thus transient fields are writing over each other.

This is undesirable, I would like to cache the table data without sharing references. Any ideas? [Edit] Understanding the situation better now, I believe my question boils down to the following: Is there anyway to disable first level cache for a specific domain class while still using second level cache?

  • Changing GORM table name

    - by Matthias Hryniszak
    Hi I'm fighting to get the following mapping working in Grails 1.3.1 and MySQL: class Login { int id String email static mappings = { table 'my_table' id column: "Mgr_id" version: false } } No matter what I do the queries that are being issued refer to "schema.login" table instead of "schema.my_table". This is very frustrating... Can anyone answer why this might not be working?

  • Maintaining the position of columns in Grails/GORM

    - by firnnauriel
    Is there a way to fix the position of the columns in a domain? I have this domain: class SnbrActVector { int nid String term double weight static mapping = { version false id(generator: 'assigned') } static constraints = { nid(blank:false) term(blank:false) weight(blank:false) } } This is the schema of the table generated: CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `weight` double NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `nid` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci It seems that the order of the columns were reversed. Is there a way to make it like this? (order is nid, term, weight) CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `nid` int(11) NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `weight` double NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

  • How to force grails GORM to respect DB scheme ?

    - by fabien-barbier
    I have two domains : class CodeSet { String id String owner String comments String geneRLF String systemAPF static hasMany = [cartridges:Cartridge] static constraints = { id(unique:true,blank:false) } static mapping = { table 'code_set' version false columns { id column:'code_set_id', generator: 'assigned' owner column:'owner' comments column:'comments' geneRLF column:'gene_rlf' systemAPF column:'system_apf' } } and : class Cartridge { String id String code_set_id Date runDate static belongsTo = CodeSet static constraints = { id(unique:true,blank:false) } static mapping = { table 'cartridge' version false columns { id column:'cartridge_id', generator: 'assigned' code_set_id column:'code_set_id' runDate column:'run_date' } } Actually, with those models, I get tables : - code_set, - cartridge, - and table : code_set_cartridge (two fields : code_set_cartridges_id, cartridge_id) I would like to not have code_set_cartridge table, but keep relationship : code_set -- 1:n -- cartridge In other words, how can I keep association between code_set and cartridge without intermediate table ? (using code_set_id as primary key in code_set and code_set_id as foreign key in cartridge). Mapping with GORM can be done without intermediate table?

  • How to express "where value is in dynamic list" in HQL/GORM?

    - by xcut
    For a grails application, I need to find a list of objects whose "attr" is one in a dynamic list of strings. The actual HQL query is more complex, but the bit I need help with is this: def result = MyObject.executeQuery("select o from MyObject as o where o.attr in :list", [list: aListOfStrings]) This is obviously not the right syntax, Grails throws it back at me as an "unexpected token", being the :list parameter. Is this possible in HQL? I don't particularly want to use Criteria in this part of the codebase.

  • How to set offset in GORM when using createCriteria?

    - by firnnauriel
    I'm just wondering if it's possible for 'createCriteria' to specify the paginateParams (i.e. offset) similar to dynamic finder (findAll, etc.) Note that this code is not working since 'offset' is not documented in http://www.grails.org/doc/1.2.1/ref/Domain%20Classes/createCriteria.html def c = SnbrItemActDistance.createCriteria() def results = c.list { eq('iid', newsId) ge('distance', cap) maxResults(count) offset(offset) order('distance', 'desc') }
