Como criar uma entidade EAV?

Como criar uma entidade EAV?

Essa é uma pergunta que aparece muito na web. Existem alguns bons artigos de blog que explicam como fazer isso, mas nenhum deles é satisfatório para mim.
Então, decidi fazer uma pergunta auto-respondida e explicar como faço ... e parece funcionar.

Há muito código aqui. Para ler corretamente, classifique as respostas por 'mais antigas'.

Parte 1

Para o propósito desta demonstração, eu vou criar um módulo, vamos nomear Easylife_Newsque contém uma entidade chamada Article.
O módulo vem com código CRUD completo para back-end, incluindo a seção para gerenciar atributos e algumas listagens simples de front-end e página de exibição para cada artigo. Ele também adiciona um item de menu no menu superior à lista de artigos.
Ele também contém reescritas de URL, feed RSS e trilhas de navegação para o front-end. Esta entidade terá 4 atributos: Title, Short Description, Description, Publish Datealém dos queridos do sistema ( created_at, updated_at, status, in_rss, url_key).
O módulo deve conter os seguintes arquivos.

app/etc/module/Easylife_News.xml - o módulo de declaração:

<?xml version="1.0"?>
<config>
    <modules>
        <Easylife_News>
            <active>true</active>

            <depends>
                <Mage_Catalog /><!-- some classes extend one class from the catalog module to avoid duplicating it -->
             </depends>
        </Easylife_News>

Shivam

Verifique se a classe Easylife_News_Block_Adminhtml_Article_Edit_Tab_Attributesexiste e está no lugar certo.
Marius

sim a sua existência com estrutura de pastas apropriada
Shivam

verifique se a <blocks>tag existe no seu arquivo config.xml. Por algum motivo, a chamada do método getBlock('easylife_news/adminhtml_article_edit_tab_attributes')retorna false. isso significa que o bloco não existe ou não pode ser instanciado. Para evitar problemas como esse, recomendo que você use esta ferramenta github.com/tzyganu/UMC1.9 para criar seu módulo de entidade eav.

Se eu tiver um artigo com um atributo de imagem e adicionar validação adicional a um _beforeSavemétodo de artigo , ele lançará a Mage_Core_Exception. Recebo erros de conversão de Array para String da Image ao editar. Acredito que isso ocorre porque a chamada para setArticleDatanão leva em consideração, os dados da imagem sendo enviados como uma matriz, especialmente quando você está editando. Isso é um erro no seu código ou na minha abordagem ao lidar com validação adicional? FYI meu em torno do trabalho atual envolve me fazendo unset($articleData['image']);antessetArticleData

Agora você precisa adicionar uma imagem de espaço reservado, caso planeje usar atributos de imagem.
A imagem deve ser colocado em skin/frontend/base/default/images/placeholder/article.jpg. Basta copiar o logotipo padrão do magento e colocá-lo lá.

É isso aí. Simples, certo?
