Postgres + Grails

Boa noite pessoal,

Bom, estou lendo o livro Grails in Action e acabei de configurar o postgres 9.1 para trabalhar com o framework, criei meu primeiro dominio, porem estou com uma dúvida.

Quando o hibernate criou a tabela apartir do meu dominio, ele criou um campo ID auto incrementavel que eu ja esperava, mas criou tambem um campo version... e eu não entendi o porque disso.

Tambem gostaria de saber se é possivel modificar o banco... por exemplo o tamanho do campo nome de 255c para 100c por exemplo, devo fazer isso atravez do dominio?

Acabei de ler o livro Groovy in Action até a página 400 e entrei agora no Grails in Action, então se essa questão for respondida mais pra frente, por favor me confirmem.

Ola Daniel.

1. Campo version
É o campo que o Grail usa para controlar a concorrência de acessos às tabelas. Fique tranquila, o Grails usa esse campo sem que você perceba.

2. Reduzir tamanho de campo
Isso é uma questão sobre o comportamento do Hibernate, na verdade. O Hibernate - consequentemente o GORM - atualiza o banco quando configurado para isso, MAAAAS tem certas coisas que ele não faz. As que tenho conhecimento são:
- Não exclui um campo da tabela caso seja excluido do mapeamento
- Não exclui tabela caso ela deixe de ser mapeada
- Não excluir relacionamento caso sejam excluidos dos mapeamentos
Então, acredito que o caso de reduzir o tamanho de um campo seja um desses casos.

Abraços.

Vlw José.

Agora estou com um pequeno problema com o Grails.

Acabei de criar o projeto Habbub que o livro Grails in Action apresenta, porem estou a 1 hora, ou mais tentando descobrir de onde vem esse erro:

| Packaging Grails application.....
| Error 2012-06-25 23:04:17,582 [main] ERROR hbm2ddl.SchemaUpdate  - Unsuccessful: create table user (id int8 not null, version int8 not null, date_created timestamp not null, homepage varchar(255) not null, password varchar(255) not null, user_id varchar(255) not null, primary key (id))
| Error 2012-06-25 23:04:17,582 [main] ERROR hbm2ddl.SchemaUpdate  - ERROR: syntax error at or near "user"


Estou conectando com o Postgres e consegui efetuar uma ligação no meu projeto anterior (Quote), mas nesse parece impossivel.

Ate o momento criei um domain chamado User:

package com.grailsinaction
class User {
	String userId
	String password
	String homepage
	Date dateCreated 
}


e a config do meu banco é a seguinte:

dataSource {
    pooled = true
    driverClassName = "org.postgresql.Driver"
	dialect = org.hibernate.dialect.PostgreSQLDialect
    username = "postgres"
    password = "senha"
	dbCreate = "create-drop"
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = true
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    development {
		dataSource {
			dbCreate = "update" // one of 'create', 'create-drop','update'
			url = "jdbc:postgresql://localhost:5432/hubbub"
			driverClassName = "org.postgresql.Driver"
			username = "hubbub_user"
			password = "senha"
			dialect = net.sf.hibernate.dialect.PostgreSQLDialect 
		}
    } 
    test {
		dataSource {
			dbCreate = "update" // one of 'create', 'create-drop','update'
			url = "jdbc:postgresql://localhost:5432/hubbub"
			driverClassName = "org.postgresql.Driver"
			username = "hubbub_user"
			password = "senha"
			dialect = net.sf.hibernate.dialect.PostgreSQLDialect 
		}
    }
    production {
		dataSource {
			dbCreate = "update" // one of 'create', 'create-drop','update'
			url = "jdbc:postgresql://localhost:5432/hubbub"
			driverClassName = "org.postgresql.Driver"
			username = "hubbub_user"
			password = "senha"
			dialect = net.sf.hibernate.dialect.PostgreSQLDialect 
		}
     }
 }


O jar do postgres ja esta nas dependencias, então ja adianto que não é esse o problema.

Daniel,

se não me engano, no Postgres não é permitido haver uma tabela "user".

0
Ah... acabei de achar algo.

http://stackoverflow.com/questions/4350874/unable-to-use-table-named-user-in-postgresql-hibernate

Não é que não aceite, mas, para que o Postgres aceite, precisaria estar entre aspas o que, por padrão o Hibernate não faz.

Sugestão: apenas crie a tabela "User" na tua base por baixo que o resto o Hibernate faz (campos, relacionamentos, etc). Mas tua configuração "dbCreate" deve estar "update" e não "create".

Abraços.

Acabei mudando o nome da classe para Usuario, encontrei uma material semelhante a esse que você referenciou.

Agora a tabela foi criada, mas ainda existe um erro:

| Failure:  testFirstSaveEver(com.grailsinaction.UsuarioIntegrationTests)
|  junit.framework.AssertionFailedError
	at junit.framework.Assert.fail(Assert.java:48)
	at junit.framework.Assert.assertTrue(Assert.java:20)
	at junit.framework.Assert.assertNotNull(Assert.java:218)
	at junit.framework.Assert.assertNotNull(Assert.java:211)
	at com.grailsinaction.UsuarioIntegrationTests.testFirstSaveEver(UsuarioIntegrationTests.groovy:10)


Estou na página 100 do livro e ele volta a fazer os testes integrados do Grails, mas logo de cara ve que o arquivo sample que o Grails 2.0.4 gera é extremamente diferente desses modelos que estão no livro, de qualquer forma decide seguir o livro.

Segue o a classe UsuarioIntegrationTests:

package com.grailsinaction

import grails.test.*

class UsuarioIntegrationTests extends GrailsUnitTestCase {

	void testFirstSaveEver() {

		Usuario usuario = new Usuario(usuarioId: 'joe', senha: 'secret', homepage: 'http://www.grailsinaction.com')
		assertNotNull usuario.save()
		assertNotNull usuario.id

		def foundUser = Usuario.get(usuario.id)
		assertEquals 'joe', foundUser.usuarioId
	}

}


Devo dizer que la pra traz no livro, depois de muita tentativa e erro com o teste da aplicação Quote, eu acabei pulando essa parte, mas pelo jeito vou precisar entender o porque desse não funcionamento.

Segue minha class Usuario:

package com.grailsinaction

class Usuario {
	String usuarioId
	String senha
	String homepage
	Date dataCriacao = new Date()

static constraints = { 
	usuarioId(size:3..20, unique: true) 
	senha(size: 6..8)
	homepage(url: true, nullable: true)
	}
}


Aparentemente ele não consegue encontrar o metodo usuario.save(), ja tententei fixar o tipo da referencia como Usuario, ja tentei usar o def (dinamicamente tipado), mas não adianta.

olá eu uso o postgres em dua aplicações segue minha configuracao
dataSource {
pooled = true
driverClassName = "org.hsqldb.jdbcDriver"
username = "sa"
password = ""
}
hibernate {
cache.use_second_level_cache=true
cache.use_query_cache=true
cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider'
}
// environment specific settings
environments {
development {
dataSource {
dbCreate = "update"
driverClassName = "org.postgresql.Driver"
username = "usuario"
password = "senha"
url = "jdbc:postgresql://127.0.0.1/seu banco"

}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:hsqldb:mem:testDb"
}
}
production {
dataSource {
dbCreate = "update"
driverClassName = "org.postgresql.Driver"
username = "usuario"
password = "senha"
// url = "jdbc:postgresql://192.168.1.112/seubanco"
url = "jdbc:postgresql://127.0.0.1/seubanco"
}
}


}


eu estou usando o plugin spring-security-core
da uma olhada nesse link
http://fabiodocarmo.com/2011/01/13/simplificado-spring-security-com-grails-versao-traduzida/

ele ja resolve a questa do usuario

Obrigado manthay, mas meu problema agora não é mais o Postgres, mas sim o teste integrado do Grails.

Acho que o livro esta cobrindo uma forma de teste que ja não é mais utilizada talvez, de qualquer forma vou modificar minha configue do postgres para essa.

Grato

Pessoal,

Não se usa mais o GrailsTesteCase, mas sim o GroovyTestCade... essa é a solução

Vlw a todos pela ajuda

Oi gente, topei com este post aqui, então vou dar um up nele.

Pergunto: percebi que por padrão, quando uso o PostgreSQL com Grails, o GORM cria uma única sequence para o meu banco, que vai ser compartilhada por todas as demais tabelas.

Tem como modificar este comportamento padrão sem precisar ficar mexendo em todas as classes de domínio? Alguém sabe?

1
No "Config.groovy":

grails.gorm.default.mapping = {
id generator:'increment' // ou 'sequence' ou qualquer outra possivel que desejar
}

Henrique Lobo Weissmann (Kico)

Aliás, nessa closure define-se todo e qualquer comportamento padrão das classes de mapeamento GORM, como cache e tipos personalizados, por exemplo. Tudo que que se pode fazer na "mappging" de cada classe GORM ;)

Muito bem lembrado Yoshiriro!
Havia me esquecido completamente disto.

Pessoal,

Fiquei uma dúvida sobre o Postgres, pois ele funciona atravez de Roles.. pelo menos tive que criar um Login Role para o banco.

Eu entendo que posso determinar o perfil dos usuarios frente ao banco, mas uma vez que isso é configurado no DataSource.groovy, como posso determinar que o usuário X so pode ler do banco e o usuário Y pode ler e escrever?

O SpringSecurityPlugin cobre isso?

Olá, Daniel

Essa é uma questão que transcende o Grails e o Gorm. Todas as principais tecnologias de ORM (em Java, Rails, etc) partem do principio que você se conecta no banco sempre com o mesmo usuário. O máximo que se tem são usuários diferentes para desenvolvimento, testes e produção. Mas, em produção, mesmo que você tenha 1000 clientes cadastrados, usa sempre o mesmo login e senha para se conectar ao banco.

Esse paradigma de usuários de banco existe não só no postgres como em todos os SGBDs relacionais. O uso de vários usuários com sistemas de permissões direto no banco se justificava nos sistemas antigos, mas nos atuais, ainda mais nos sistemas Web esse recurso é descartável. Assim, quem assume a responsabilidade pelas permissões passa a ser dos sistemas que acessam o SGBD e não dele próprio.

Muito obrigado Yoshiriro, fico mais tranquilo em ouvir isso.
