[RESOLVIDO] vRaptor - Upload de imagem + formulário

mondor · Outubro 21, 2012, 2:02pm

Pessoal, estou me batendo um pouco aqui com o envio de um formulário + foto.

Vejam um exemplo:

Uma pessoa para realizar o cadastro necessita preencher suas infos (nome, cidade, etc…) e colocar a sua foto. Todos os campos são obrigatórios, incllusive a foto.

Estou enviando meu formulário via ajax. Aqui vai a primeira pergunta: ajax consegue mandar arquivo?
Segunda: Como o pessoal que usa o vRaptor consegue driblar isto?

Realizando um exemplo simplificado:

[code]
var fields = {‘pessoa.nome’ : nome, ‘pessoa.idade’ : idade, ‘foto’ : foto};
$.post(’<c:url value="/pessoa/novo"/>’, fields, function(data) {

});[/code]

Meu controller que recebe o ajax:

[code]
@Post("/pessoa/novo")
public void savePeople(Pessoa pessoa, UploadedFile foto) {
service.save(pessoa);
peopleImage.upload(foto, pessoa);

	result.use(Results.json()).from("ok").serialize();

}[/code]

Mas essa minha foto, sempre vem null! Já tentei por um objeto File dentro do meu bean Pessoa também, como Transient do hibernate e tentar pegar o arquivo por pessoa.getFoto() mas também vem null.

O vRaptor possui algum workaround para isto?

vc precisa de um plugin javascript pra conseguir isso…

tenta o uploadify

mondor · Outubro 21, 2012, 8:35pm

Olá Lucas,

Dei uma olhada no uploadify e é show de bola! Mas acho que não resolve meu problema. Veja, como é obrigatório o envio da foto, eu vou ter que fazer um controller com dois métodos ao invés de receber a foto e os dados em um só? (um método para criar a pessoa e após isto chamar o outro método para dar upload na imagem?)

Além da validação que tem de ser feita lado servidor também (por motivos de segurança da aplicação), eu teria que fazer a validação no envio da foto e se for null eu teria que apagar o registro da pessoa (resultando em SQL a mais)… Convenhamos que isto não é nada performático.

Se recebesse os dados texto do form e mais o arquivo de imagem em um só controller seria muito melhor!

Algo mais ou menos assim:

@Post("/pessoa/novo")  
public void savePeople(Pessoa pessoa, UploadedFile foto) {  
        String retValor = "ok";
        boolean dadosOK = validateFormData(pessoa);
        if (dadosOK && foto != null) {
                service.save(pessoa);  
                peopleImage.upload(foto, pessoa);  
        } else {
                retValor = "nok";
        }

        result.use(Results.json()).from(retValor).serialize();  
}

Que tal se você receber a imagem via ajax usando o uploadify. Na sua action ajax, você salva a imagem na Session do usuário que está usando.

Depois que ele terminar de preencher todos os dados, você busca essa imagem na session e remove ela de la. Dai você vai ter tudo que precisa: os dados e a imagem. Só salvar.

Lucas_Cavalcanti · Outubro 22, 2012, 7:10am

no uploadify dá pra enviar mais dados do que só o arquivo…

e fazer um SQL ou dois SQLs numa operação que envolve upload não faz a mínima diferença para performance… a menos que vc esteja desenvolvendo um facebook com milhões de usuários

kadu.m.lino · Outubro 22, 2012, 7:15am

Mondor… esse cara é a resposta do seu problema -> http://blueimp.github.com/jQuery-File-Upload/

Vou blogar sobre ele, mas ainda não arrumei tempo, mas a API dele é muito simples… vc vai fazer em 2 palitos… boa sorte

mondor · Outubro 22, 2012, 4:33pm

Fala galera! Então, as 3 respostas são bem válidas, muito obrigado!
Entretanto, vou optar por tentar usar o uploadify, pela ampla gama de opções.

Fiz um teste aqui, que não deu muito certo.:

<input type="file" name="bigImage" id="bigImage" multiple="false" />
<div id="queue"></div>

$('#bigImage').uploadify({ 'swf' : '<c:url value="/css/uploadify.swf"/>', 'uploader' : '<c:url value="/people/image"/>', 'folder' : 'images', 'buttonText': 'Selecionar arquivos', 'fileDataName': 'bigImage' });

[code]
@Post("/people/image")
public void saveBigImage(UploadedFile bigImage) {
// ideaImage.upload(bigImage, pessoa);

result.use(Results.json()).from(bigImage).serialize();

}[/code]

Porém debugando o código, essa bigImage vem sempre null! :// Alguma idéia?

mondor · Outubro 22, 2012, 4:54pm

Engraçado… Acabei de ver aqui no log:

19:26:42,029 INFO [CommonsUploadMultipartInterceptor] Request contains multipart data. Try to parse with commons-upload. 19:26:42,325 WARN [UploadedFileConverter] There was an error when uploading the file {}. Please verify if commons-fileupload jars are in your classpath or you are using a Servlet 3 Container.

Mas eu já tenho este JAR…

<dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency>

São estes jars mesmo, certo? Inclusive, verifiquei na References Libraries e estava lá: commons-fileupload-1.2.2.jar

Lucas_Cavalcanti · Outubro 22, 2012, 6:11pm

se vc ta com a ultima versao do VRaptor, tente criar esse arquivo:

@Convert(UploadedFile.class)
public class UploadedFileConverter implements Converter<UploadedFile> {

    private final HttpServletRequest request;

    public UploadedFileConverter(HttpServletRequest request) {
        this.request = request;
    }

    public UploadedFile convert(String value, Class<? extends UploadedFile> type, ResourceBundle bundle) {
        Object upload = request.getAttribute(value);
		return type.cast(upload);
    }

}

isso deve corrigir

mondor · Outubro 22, 2012, 6:19pm

òtimo! o warn sobre o commons-fileupload sumiu, porém o arquivo ainda vem null no meu controller, e o info continua aparecendo:

esse nullpointer é que estou tentando result.use(Results.json()).from(bigImage).serialize(); mas o bigImage vem null…

Lucas_Cavalcanti · Outubro 22, 2012, 6:36pm

Parameter(Filedata -> Filedata)

aparentemente o parametro do filedata tah vindo com o valor errado… tenta ver na documentação se vc tah passando a option de mudar o fileData corretamente.

Do jeito que está o UplodadedFile deveria se chamar FileData (com esse F maiusculo mesmo)

mondor · Outubro 22, 2012, 7:02pm

Boa! Quando eu vi o log de debug também pensei nisto na hora!
Dei uma olhada na documentação e não achei nada que possa mudar este comportamento. Por via das dúvidas, mudei o meu controller mesmo, sem problemas

Mas agora tá acontecendo o inverso. Provável que não esteja sabendo usar o plugin.
Consegue dar mais esta luz?

Veja:

[code]
var fields = {‘pessoa.nome’ : nome, ‘pessoa.idade’ : idade};

$(’#bigImage’).uploadify({
‘swf’ : ‘<c:url value="/css/uploadify.swf"/>’,
‘uploader’ : ‘<c:url value="/pessoa/novo"/>’,
‘folder’ : ‘images’,
‘buttonText’: ‘Selecionar arquivos’,
‘auto’ : false, // Não manda automaticamente o arquivo, só quando mandar.
‘formData’ : fields // Teoricamente, os campos do formulário
});[/code]

No submit do form:

Segundo a documentação: “To upload multiple files, add each fileID as an argument. If ?*? is passed as the first and only argument, all files in the queue will be uploaded.”

[code]
@Post("/pessoa/novo")
@OnlyLogged
public void savePeople(People pessoa, UploadedFile Filedata) {
// TODO validacao
service.save(pessoa);

if (Filedata != null) {
	peopleImage.upload(Filedata, pessoa);
}
	
result.use(Results.json()).from(Filedata).serialize();
result.use(Results.json()).from("ok").serialize();

}[/code]

Agora o meu objeto pessoa que não está vindo certinho, vem tudo vazio os atributos nome e idade… Lembrando que já fiz um teste e a variável fields está com o valor dos campos certinho!
Alguma idéia?

Obs.: ao menos agora a imagem chega certinho no controller

Lucas_Cavalcanti · Outubro 22, 2012, 7:04pm

aparentemente os dados não estão indo mesmo… dá uma olhada se vc tah vendo a doc certa do plugin…

pior dos casos vc pode separar o upload do resto do formulario e fazer soh ele via ajax.

kadu.m.lino · Outubro 24, 2012, 6:45am

Mondor, dah uma olha nesse blog…

Edifran · Outubro 24, 2012, 5:11pm

Pessoal, eu to com um problema parecido com esse, por isso não abri outro tópico.

Eu tenho no meu formulário de cadastro e edição de produto a opção de colocar ou não a foto/imagem do mesmo.
Quando eu coloco a foto beleza, mas quando eu não coloco dá um “Invalid upload” quando eu executo o validator
Essa imagem não é de cadastro obrigatório

public void altera(final Produto produto, final UploadedFile imagem) {
        validator.validate(produto);
...
...
...

Tem como eu corrigir isso?

To usando o vraptor 3.4.1
