Recuperar Valor Select com vraptor

ksio_thadeu · Abril 20, 2011, 9:35am

tenho o seguinte codigo na minha jsp

<select name="tipoVisita" id="tipo_visita" value="tipoVisita"> <c:forEach items="${tipos}" var="tipo"> <option value="${tipo}">${tipo.tipo}</option> </c:forEach> </select>

só que não consigo recuperar no controler, o tipoVisita é um objeto
classe TipoVIsita

[code]public class TipoVisita implements Serializable {

@Id
@SequenceGenerator(name="SEQ_TPVIS", sequenceName="SEQ_TIPOVISITA", allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_TPVIS")
@Column(name="tpvis_id")
private Integer id;

@Column(name="tpvis_tipo", nullable=false, length=60)
private String tipo;

@Column(name="tpvis_comentario", length=250)
private String comentario;
[/code]

Tenta isso.

<select name="tipoVisita" id="tipo_visita" value="${tipoVisita.tipo}"> <c:forEach items="${tipos}" var="tipo"> <option value="${tipo}">${tipo.tipo}</option> </c:forEach> </select>

Lucas_Cavalcanti · Abril 20, 2011, 12:15pm

a tag não tem o atributo value, ele está nas options…

no controller vc está recebendo um parâmetro chamado tipoVisita?

ksio_thadeu · Abril 20, 2011, 12:34pm

no controler esta assim

preciso receber o objeto para adicionar a uma visita

Rafael_Guerreiro · Abril 20, 2011, 1:39pm

No meu projeto eu passo só o ID e depois eu faço uma consulta e trago o objeto completo…

JSP:

        <select id="autor" name="acervo.autor.codigoAutor" class="componente" style="width: 100%;" >
		 <c:forEach var="autor" items="${listaAutor}">
			 <option value="${autor.codigoAutor}"> ${autor.nomeAutor}</option>
		 </c:forEach>
	</select>

Controller:

public void adiciona(Acervo acervo){
      //aqui eu capturo o ID do autor (que é um atributo no meu acervo) e consulto o autor
      acervo.setAutor(autorDAO.consultar(acervo.getAutor().getCodigoAutor()));
      //restante
}

-Edit-
dá uma olhada neste tópico também:
http://www.guj.com.br/java/236139-resolvidocombobox-usando-vraptor

-Edit-
o “name” do seu select tem q ser igual ao nome do parametro que vc recebe, exemplo:

<input name="brocolis" />

public void fazAlgoComBrocolis(String brocolis){
      //fazendo algo
}

ksio_thadeu · Abril 20, 2011, 3:20pm

Mais não tem como recuperar o objeto inteiro para evitar realizar uma consulta no banco?

Lucas_Cavalcanti · Abril 20, 2011, 3:56pm

se o nome do parâmetro é “tipo”, o name do select tb tem que ser “tipo”

ksio_thadeu · Abril 25, 2011, 6:53am

coloquei da seguinte maneira

<select name="tipo"> <c:forEach items="${tipos}" var="tipo"> <option value="${tipo}">${tipo.tipo}</option> </c:forEach> </select>

e recebi a seguinte exception

Lucas_Cavalcanti · Abril 25, 2011, 10:08am

tipoVisita não é um enum?

ksio_thadeu · Abril 25, 2011, 10:29am

não, TipoVisita é uma Classe que

[code]public class TipoVisita implements Serializable {

@Id
@SequenceGenerator(name="SEQ_TPVIS", sequenceName="SEQ_TIPOVISITA", allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_TPVIS")
@Column(name="tpvis_id")
private Integer id;

@Column(name="tpvis_tipo", nullable=false, length=60)
private String tipo;

@Column(name="tpvis_comentario", length=250)
private String comentario;[/code]

os tipos são recuperados no banco de dados e populam o select

Lucas_Cavalcanti · Abril 25, 2011, 10:53am

então o select tem que se chamar tipo.id e o value das options também tem que ser o id do tipo…

ksio_thadeu · Abril 25, 2011, 1:38pm

Por exemplo:
eu tenho a o seguinte codigo

[code]public class Visita implements Serializable {

@Id
@AttributeOverrides({
    @AttributeOverride(name="visID", column=@Column(name="vis_id", nullable=false, precision=10, scale=0)),
    @AttributeOverride(name="tecID", column=@Column(name="vis_tec_codext", nullable=false, precision=10, scale=0)),
    @AttributeOverride(name="visitaSequencia", column=@Column(name="vis_sequencia", nullable=false, precision=10, scale=0))
})
@Column(name="vis_id", nullable=false)
private VisitaID id;
 .
 .
 .


@ManyToOne
@JoinColumns({
   @JoinColumn(name="vis_cli_codigo", referencedColumnName="cli_codext", insertable=true, updatable=true),
   @JoinColumn(name="vis_cli_filial", referencedColumnName="cli_fili", insertable=true, updatable=true),
   @JoinColumn(name="vis_cli_regiao", referencedColumnName="cli_regi", insertable=true, updatable=true)
})
@Fetch(FetchMode.JOIN)
@Cascade(CascadeType.SAVE_UPDATE)
private Cliente cliente;

[/code]

queria saber se consigo na minha jsp adicionar o o objeto cliente que esta na minha seção a visita
tipo

<input type="hidden" name="visita.cliente" value="${cliente}/>
onde cliente foi enviado pelo controller
ou eu tenho que fazer

pois acho que do primeiro jeito seria mais facil, como se fosse um visita.setCliente(cliente);

Lucas_Cavalcanti · Abril 25, 2011, 1:51pm

vc precisa passar pelo id mesmo…

lembre-se que vc está gerando um HTML, e no html não existe uma representação de Cliente…

passando o id, o hibernate já consegue se virar

ksio_thadeu · Abril 28, 2011, 8:04am

Obrigado Lucas

Agora estou com problema parar recuperar um valor que o usuario selecionou em um checkbox

JSP

<c:forEach items="${emails}" var="email" varStatus="s"> <input type="checkbox" name="visita.email[${s.index}].email" id="e-mail" value="${email}">${email}<br/> </c:forEach>

Classe Visita

[code]@Entity
@Table(name=“visita”, schema=“Tecnicos”)
public class Visita implements Serializable {

@Id
@AttributeOverrides({
    @AttributeOverride(name="visID", column=@Column(name="vis_id", nullable=false, precision=10, scale=0)),
    @AttributeOverride(name="tecID", column=@Column(name="vis_tec_codext", nullable=false, precision=10, scale=0)),
    @AttributeOverride(name="visitaSequencia", column=@Column(name="vis_sequencia", nullable=false, precision=10, scale=0))
})
@Column(name="vis_id", nullable=false)
private VisitaID id;

//outros atributos da classe

@OneToMany(mappedBy="visita", fetch=FetchType.LAZY)
@Cascade(CascadeType.ALL)
private Collection<EmailEnvio> email;[/code]

quando executo a aplicacao ocorre um stackOVerflow

Valeu, era isso mesmo.
