Question

我有一个只有一个基表的自定义实体，它被带有字段field_a的节点引用。现在我想创建这两个实体（节点和我的自定义实体）之间的关系。我可以得到结果，但我没有得到视图字段部分中列出的节点字段。

//自定义实体的基表是“clinical_trial_research_sites”

function clinical_trial_views_data_alter(&$data) {
 $data['clinical_trial_research_sites']['node'] = array(
    'title' => t('Clinical Trial'),
    'help' => t('Field Reference Appear in Location Content type.'),
    // Information of the referenced table!!
    'relationship' => array(
      'handler' => 'views_handler_relationship',
      'label' => t('Location'),
      'base' => 'field_data_field_site_comp_code', // node field table name
      'base field' => 'field_site_comp_code_value', // field column name of node field
      'relationship field' => 'site_comp_code', // This is referencing field in my custom entity
    ),
  );
}

我可以让sql工作，内部联接工作但是视图没有列出节点的所有字段，因为我想显示节点中的一些字段!!我想我错过了一些信息来告诉观点，关系不仅仅是字段表，而是整个节点!!

我通过复制entityreference中的一些代码来修复它。我必须为这种关系使用不同的视图处理程序，并为该关系添加其他属性

function clinical_trial_views_data_alter(&$data) {

  $data['clinical_trial_research']['clinical_trial_research_sites'] = array(
    'title' => t('Clinical Trial Research Sites'),
    'help' => t('Field Reference Appear in Clinical Trial Research Sites.'),
    'relationship' => array(
      'handler' => 'views_handler_relationship',
      'label' => t('Clinical Trial Research Sites'),
      'base' => 'clinical_trial_research_sites',
      'base field' => 'study_num',
      'relationship field' => 'study_num',
    ),
  );
  // The reference field in the node entity is not entity reference , its just a basic text field
  $data['clinical_trial_research_sites']['site_comp_code']['relationship'] = array(
    'handler' => 'views_handler_relationship_entity_reverse',
    'field_name' => 'field_site_comp_code',
    'field table' => 'field_data_field_site_comp_code',
    'field field' => "field_site_comp_code_value",
    'base' => 'node',
    'base field' => 'nid',
    'title' => t('Referencing entity'),
    'help' => t('Field Reference Appear in Location Content type.'),
    'title' => t('Location'),
  );
}
