Call static method from variable class

Question

I have some methods which do the same thing, but with different files and entities, which need to be persisted on the database.

These methods calls an static method on each entity. This static method reads an string and return the entity object with the properties set from the string.

To automate this process I abstracted the repetitive work with a method(atualizaDB) and I call this method passing by argument the differences between each function.

The problem happens when the atualizaDB tries to call the static method, returning FatalErrorException: Error: Class not found. What can I do to correct this error?

Thanks.

<?php

namespace AGC\Bundle\AGCPedidosBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class AtualizacaoController extends Controller
{
    private function atualizaDB($arquivo, $entidade)
    {
        // Arquivo de atualização
        $arquivoTXT = rtrim($this->container->getParameter('files_dir'), ' '.DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR.$arquivo.'.txt';

        // Verifica se o arquivo existe
        if (!is_file($arquivoTXT)) {
            return new Response('Erro: Arquivo "'.$arquivoTXT.'" não encontrado!', 404, array('Content-type'=>'text/plain'));
        } else {
            // Abrimos o arquivo
            $arquivoTXTArr = file($arquivoTXT);

            // Verifica se conseguiu abrir o arquivo
            if ($arquivoTXTArr === false) {
                return new Response('Erro: Falha ao abrir o arquivo "'.$arquivoTXT.'".', 500, array('Content-type'=>'text/plain'));
            } else {
                try {
                    // Percorre as linhas do arquivo
                    for ($i=2; $i<count($arquivoTXTArr); $i++) {
                        // Mapea o objeto à partir da linha do arquivo
                        $registroObj = $entidade::fromTXT($arquivoTXTArr[$i], $this->getDoctrine());

                        // Procura o registro no banco de dados
                        $registroFromDB = $this->getDoctrine()->getRepository('AGCPedidosBundle:'.$entidade)->findOneBy(array('codigo'=>$registroObj->getCodigo()));

                        // Achou o registro?
                        if ($registroFromDB === null) {
                            // Adiciona um novo registro ao banco de dados
                            $this->getDoctrine()->getManager()->persist($registroObj);
                        } else {
                            // Atualiza o registro no banco de dados
                            $registroFromDB->updateObject($registroObj);

                            // Persiste os dados
                            $this->getDoctrine()->getManager()->persist($registroFromDB);
                        }
                    }

                    // Da commit nos dados
                    $this->getDoctrine()->getManager()->flush();

                    // Responde com sucesso
                    return new Response('Ok', 200, array('Content-type'=>'text/plain'));
                } catch (\Exception $e) {
                    throw new \Exception($e->getMessage(), $e->getCode(), $e->getPrevious());
                }
            }
        }
    } 

    public function clientesAction()
    {
        return $this->atualizaDB('nClientes', 'Cliente');
    }

    public function fornecedoresAction()
    {
        return $this->atualizaDB('nFornecedores', 'Fornecedor');
    }

    public function gruposAction()
    {
        return $this->atualizaDB('nGrupo', 'Grupo');
    }

    public function pedidosAction()
    {
        return $this->atualizaDB('nPedidos', 'Pedido');
    }

    public function vendedoresAction()
    {
        return $this->atualizaDB('nVendedores', 'Vendedor');
    }
}

Edited to include the full error returned without prepend the namespace to the class name:

How about you provide the full error message and the code around the location of the error. — Phil

check $entidade variable i think object not correctly passed use serialize and unserialize — Pouya Darabi

This is a namespace issue. When using variables for class names, you need to provide the full class name including namespace.

Assuming all your Cliente, Fornecedor, Grupo, etc classes are in the same namespace (probably AGC\Bundle\AGCPedidosBundle\Entity), you can probably get away with something like this...

private function atualizaDB($arquivo, $entidade) {
    $entidade = '\\AGC\\Bundle\\AGCPedidosBundle\\Entity\\'.$entidade;

    // and the rest...
}

This doesn't worked. That was the error message right now. Class 'AGC\Bundle\AGCPedidosBundle\Entity\\AGC\Bundle\AGCPedidosBundle\Entity\Cliente' does not exist

@Danniel could you edit your question to include any updated code?

Danniel Magno Over a year ago

thanks for the help. I have just changed what you have suggested. I have prepended the namespace to $entidade.

Phil Over a year ago

@DannielMagno Like I said, update the code in your question. The error message makes it look like your prepending the namespace incorrectly and / or twice

Danniel Magno Over a year ago

thanks for the reply. I revised the code, using your instructions, and it worked very well. Thanks for the help.
