Listando atributos de dois Objetos com BootStrap

JamesplayHard · Novembro 5, 2021, 5:08pm

Olá a todos, estou tendo problemas ao listar os atributos de dois objetos em uma tabela feita em bootstrap. O problema é que tabela só aceita listar atributos de uma intancia por vez. Mas creio que o problema seja implementação do controller, ou seja, o cliente teria que enxergar os atributos, entra-los para então lista-los. Abaixo vai o trexo do código do Controller que é responsável por lista-los e meu front-end em HTML.

Controller:

@GetMapping("clientes-adicionadas")	
public ModelAndView listagemClientes(Cliente cliente, Pessoa pessoa){

	ModelAndView mv = new ModelAndView();
	mv.setViewName("Cliente/listClientes");

	cliente.setPessoa(pessoa);
	mv.addObject("clienteList",clienteRepositoy.findAll());
	
	return mv;	
}

Opa. Acho que esse controller não precisa receber o cliente e a pessoa como parâmetro não. Eles nem estão sendo usados.

Okay, verdade já removi. Era porque estava tentando outraz formas e ficou esse resíduo. Mas mesmo removendo continua dando errro:

org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'nome' cannot be found on object of type 'br.pro.james.drogaria.domain.Cliente' - maybe not public or not valid?

Existe a propriedade nome na classe Cliente? Acho que nome é uma propriedade de Pessoa, ou seja, para acessar o nome, vc deveria fazer assim:

<td th:text="${clientes.pessoa.nome}"></td>

Seria bom mudar essa variável clientes para apenas cliente no template.

Lucas_Camara · Novembro 5, 2021, 7:48pm

Veja minha resposta. Tinha atualizado ela bem na hora em que vc respondeu.

Retorna estes erros:

Lucas_Camara · Novembro 5, 2021, 7:55pm

Execute em modo debug e veja se, ao recuperar os clientes do banco

clienteRepositoy.findAll()

a propriedade pessoa de cada cliente está preenchida.

Uma coisa, a pessoa será uma propriedade obrigatória do cliente ou poderá ter clientes sem uma pessoa?

No seu outro post, vc tinha colocado um print dos dados da tabela cliente, onde haviam registros onde a pessoa estava NULL. Se ainda estiver assim, provavlmente, será o que está causando esse erro no template do thymeleaf.

JamesplayHard · Novembro 5, 2021, 7:59pm

Relação de composição

Lucas_Camara · Novembro 5, 2021, 7:59pm

Mas a nível de banco de dados mesmo, a coluna pessoa na tabela cliente poderá ou não ser NULL?

JamesplayHard · Novembro 5, 2021, 8:03pm

Não poderá, pois para cliente existir ele precisa ser uma pessoa. Eu tinha botado como NULL para rodar a aplicação. Então eu terei que botar com NOT NULL? certo?

Lucas_Camara · Novembro 5, 2021, 8:14pm

Para evitar esse erro na tela, a coluna de pessoa na tabela de cliente deve está preenchida.

JamesplayHard · Novembro 5, 2021, 8:14pm

coloquei como NOT NULL, agora dar esse erro:

org.springframework.expression.spel.SpelEvaluationException: EL1007E: Property or field ‘codigo’ cannot be found on null

Lucas_Camara · Novembro 5, 2021, 8:16pm

A coluna codigo_pessoa que não pode ser NULL. Senão a propriedade pessoa na classe Cliente também ficará NULL. Então quando a tela tentar ler a propriedade nome, vai dá erro, pq vai tentar obter de uma referência NULL.

Esse codigo deve ser a chave primária, e ela não pode ser nula mesmo.

Onde vc está usando o clientes.codigo no template? No print que vc mandou, não tem.

Qdo for mandar o template, manda o código mesmo. Evite mandar imagens

JamesplayHard · Novembro 5, 2021, 8:35pm

Eu tentei, mas parece buga, ele reconhece o bootstrap e cria a tabela em vez do código. haha

E eu não estou usando clientes.codigo. Mas aparece no console.

Lucas_Camara · Novembro 5, 2021, 8:39pm

É estranho pq se aparece isso:

Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: “clientes.codigo” (template: “Cliente/listClientes” - line 71, col 38)

em algum lugar (provavelmente nesse template: Cliente/listClientes), o thymeleaf está tentando interpretar essa expressão clientes.codigo. Talvez seja algum cache, não sei.

JamesplayHard · Novembro 5, 2021, 8:48pm

Assim, logo abaixo, vou botar o print, pois de alguma forma O GUJ reconhece os componetes do boostrap e não mostra todo o código.

O que acontece é o seguinte: Ao listar eu quero que tenha a opção de editar e excluir.

Lucas_Camara · Novembro 5, 2021, 8:52pm

Vc tem que formatar o código usando esse botão do editor: </>

Lucas_Camara · Novembro 5, 2021, 8:56pm

Confesso que não estou entendendo pq está dando erro nessa expressão clientes.codigo. Realmente teria que ver como a lista de clientes está sendo retornada do repositório e ver se todas as propriedades estão corretamente preenchidas.
