Grails GORM implementation for the MongoDB document oriented database

This plugin is no longer maintained. Please consider using the official Grails MongoDB Plugin: https://grails.org/plugin/mongodb

MongoDB GORM plugin for Grails

MongoDB is a scalable, high-performance, schemafree and production ready NoSQL database. This plugin implements the GORM functionality for MongoDB. Under the hood it uses Morphia as a lightweight type-safe library for mapping domain classes to/from MongoDB.

You will find a list of all domain class methods and other information in the User Guide

Built with IntelliJ IDEA and kindly supported with JProfiler

gorm-mongodb's Issues

Domain.list() return MorphiaIterator when GORM semantics are slightly different

I am new to grails and recently moved from the mongodb plugin to this plugin. I pass a Domain.list() from my controller to gsp file. This plugin returns a MorphiaIterator while the gsp expects something more along the lines of a list. I'm not sure what grails/gorm actually uses but the semantics are different enough that I need to create my own list from the MorphiaIterator.

Runtime Error

Hi,
I'm getting this exception when try to create a simple object with

Document d = new Document(params)

"
URI
/MongoDbCloudDoc/document/create
Class
org.springframework.beans.PropertyBatchUpdateException
Message
Failed properties: Property 'transactionManager' threw exception; nested exception is java.lang.IllegalStateException: Cannot locate GORM API implementation. You either don't have a GORM implementation installed (such as the Hibernate plugin) or you are running Grails code outside the context of a Grails application.
"

I'm configuring my Datasource.groovy like this:

mongodb {
host = 'localhost'
port = 27017
databaseName = 'clouddb'
}

and my domain class have the annotation

@com.google.code.morphia.annotations.Entity

I'm using Grails 2.0.0.M2 and MongoDB 2.0

Thank you!

ps: How can I highlight codes?

Unable to resolve class

With grails 2.4.4 when i try to use the plugin and compile the project, the plugin fails to import all these classes

import com.google.code.morphia.annotations.Transient
import com.google.code.morphia.annotations.Embedded;
import com.google.code.morphia.annotations.Id;
import com.google.code.morphia.annotations.Version;

finally throwing

Getting exception "com.mongodb.BasicDBObject cannot be cast to com.mongodb.DBRef"

Hi,
I have a mongo domain class called MyClass, which contains a non-Id member variable called "Long myMember". When I call the GORM method MyClass.findByMyMember(someValue), I get the java.lang.ClassCastException noted in the title. If I change findByMyMember to findAllByMyMember(someValue), it doesn't complain initially and simply returns an object of type com.google.code.morphia.query.MorphiaIterator@284eb041. But, if I now attempt to access it.next(), it once again gives the same exception, for which the stacktrace is below:

Btw I'm not able to join the Grails User mailing lists as access to new users has been broken for at least a few weeks now, and reporting that issue on IRC and Twitter hasn't helped. Otherwise I would've asked the question there first before opening an issue. Thanks for any help! Let me know if you need more information,

Extending Classes raised MultipleId complaint

Environment: Grails 1.3.6, mongodb-morphia-0.6

I have an abstract class, BaseDomain:

abstract class BaseDomain {
    Date dateCreated
    Date lastUpdated
}

Which is extended by Person:

class Person extends BaseDomain {
    String firstName
    String lastName
}

When starting up my Grails app, I get the following error:

adding domain class com.redshoe.live.domain.entity.Person to morphia
2011-02-23 23:02:35,891 [main] ERROR plugins.DefaultGrailsPlugin  - Error processing mongodb domain Artefact > com.redshoe.live.domain.entity.Person: Number of violations: 2
MultipleId complained about com.redshoe.live.domain.entity.Person. : More than one @Id Field found (_id, _id).DuplicatedAttributeNames complained about com.redshoe.live.domain.entity.Person.id : Mapping to MongoDB field name '_id' is duplicated; you cannot map different java fields to the same MongoDB field.

This error only occurs if the superclass also resides within the grails-app/mongo source folder (I tried moving the abstract class out just to check). Unfortunately, that is not a feasible solution for all my classes since I have another class extending Person, and I get the same error.

errorr in the install script

mongodb-morphia-0.8.1/src/groovy/grails/plugins/mongodb/ast/MongoDomainASTTransformation.groovy: 174: Mixing private and public/protected methods of the same name causes multimethods to be disabled and is forbidden to avoid surprising behaviour. Renaming the private methods will solve the problem.

did it support "unique" save?

hi, I use this plugin now. did it support unique field save only one time?
like this:
class User{
String name;
static constraints = {
name(blank: false, unique: true)
}
}
def user1=new User("myname");
def user2=new User("myname");
user1.save();
user2.save();// the unique field "name" say it can't save, but now it can save, use db.User.find(), show same name, different ObjectId.

(obvious) Don't think this is working with Grails 1.4

I'm fairly new to grails. I was able to install the plugin using grails 1.4, but when I tried to create a domain class I got a compilation error. I then grabbed the source, ran grails upgrade and then grails package-plugin, the result of which was a different exception. Just putting this here so folks know that it's not ready for grails 1.4 just yet.

There is a dummy validate() function to work around the previous issue I submitted where the validate() function is not found on the domain objects.

Advanced Querying using this plugin

Hi,

I have been wanting some information on how to do some more advanced queries on the Mongo DB using the Grails Morphia plugin. I want to use query operators like $where, $or, etc.

I tried doing something like this but it didn't work,

def list = TestDomain.findAll(["where": "this.obj1.obj2.obj3 == 'dud' || this.obj1.obj2 == 'notdud' "], [max:100, validation: "false"])

But it seems to give me a validation error. Nevertheless I'm still not sure if this is the correct syntax or not. Haven't found anything on the net about this.

In the Morphia Library, it appears that you can do a DomainObject.where() and pass the Java Script condition as an argument. I really need this urgently as I won't be able to use Morphia without having OR / WHERE query options in my application.

Could you please let me know how this can be done from within the Grails Morphia Plugin?

Cheers,

Varun
