gorm

I have a table T with columns A & C, from which I would like to retrieve an average count like so: select avg(AC) as AV from ( select A, count(1) as AC from T where C = 1 group by A ) How do I accomplish this in GORM? GRAILS version 2.2.0 I tried following the documentation but there are no good examples. I couldn't even get the subquery to work :( Update I was able to get the count portion to work. Still now sure how to get the average since I don't know how to select from a query. def tc = T.createCriteria() def tCounts = tc.buildCriteria { and { eq 'C', 1 } projections { groupProperty 'A'

I have 2 pieces of my puzzle: 1) a no-Grails project named core-module with standalone GORM: dependencies { compile 'org.grails:grails-datastore-gorm-mongodb:6.0.4.RELEASE' compile 'org.grails:grails-validation:3.2.3' } and domain classes like: import grails.gorm.annotation.Entity @Entity class Module { String id String tags } the GORM-ing is initialized by Map config = new Yaml().load this.class.getResource( '/application.yml' ).text new MongoDatastore( config, Module, UserAccount ) and the domain classes are working as they would in a Grails app. 2) a Grails 3.2.3 app: dependencies { //

I have a problem doing a query. That I want to do is access with a query to the data in my "String code" in MyDomainA through a query from MyDomainB. The relationship between the tables is unidirectional one to one. Is possible use a gorm way to do this?? Domain A: class LicenceType { String code String description Double price static constraints = { } } TABLE DOMAIN A code description A this is A B this is B C this is C Domain B: (have the unidirectional relationship) class VoiceUser { LicenceType licenceType String username String email String nameID } TABLE DOMAIN B User 1 2 3 4 That I want

After upgrading from Grails 2.2.4 to 2.3.8 I'm getting java.lang.AbstractMethodError: grails.orm.HibernateCriteriaBuilder.or(Lgroovy/lang/Closure;)Lorg/grails/datastore/mapping/query/api/Criteria; in a query class Trip { TripParticipant driver, passenger static namedQueries = { byParticipant { UserAccount ua, name = null -> or { for( n in ( name ? [ name ] : [ 'driver', 'passenger' ] ) ) { eq "${n}.account", ua } } } } } class TripParticipant { UserAccount account boolean rated = false } any ideas? TIA UPDATE http://www.file-upload.net/download-8906460/dependency-report.txt.html is the output

Consider two domain classes; Job and Quote. A Job has many Quotes but a Job also has an accepted quote. The accepted quote is nullable and should only be set once a particular Quote has been accepted by a user. I have the relationships mapped as follows (simplified for the purpose of illustration). class Job { String title Quote acceptedQuote } class Quote { Job job BigDecimal quoteAmount } The resultant tables are exactly what I require (at least aesthetically) but the problem arises when I go and save a Quote. The Quote is saved successfully with a jobId as per the logic in my code but

I'm having trouble selecting items from a list of domain objects based on a value in an enum list. My domain object looks like this: class Truck { static hasMany = [ makes: Make ] } where a Make looks like this: enum Make { KENWORTH, MACK, VOLVO } I'm not really sure how do something like Truck.findByMake(Make.MACK) to give me all of the Trucks that have this Make in their list of Makes. That call gives me this error: No property found for name [make] for class [class Truck] Any ideas? Grails 1.2.2. This one's tricky and not supported by the dynamic finders. I also don't know how to do this

I'm building a multi tenant application with Grails and I want to keep separate databases. I need to change the url dynamically at runtime to point GORM to different database. I have a front-end acting as a balancer distributing requests to a cluster of backend hosts. Each backend host runs a Grails 2.3.5 instance and a mysql-server with several databases (one per tenant). I would like to change dataSource dynamically so that GORM can access domain entities on the right database. Any ideas ? Thanks You can configure multiple data source in your DataSource.groovy, have a look in the blog . In

I have to make a Grails 3.3.0 web interface for my internship with PostgreSQL version 10.1 as database and spring-security-core version 3.2.0. I used version 42.1.4 as a JDBC driver for PostgreSQL. I've installed PostgreSQL on my Linux laptop and created the webInterfaceDev database with the user postgres. However, every time I want to start the project I get an error that the column this_.id does not exist. This is the error that I get: 2017-11-16 14:42:21.464 ERROR --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : ERROR: column this_.id does not exist Position: 8 2017-11-16 14:42:21.504
