Drupal 7 Drupal 7节点\u保存完整性约束冲突

我必须从myModule中的自定义代码中更新一些nodereference字段。这必须在插入特定类型的新节点时完成，因此我实现了hook_node_insert，如下所示：

function myModule_node_insert($node){
    $settings = _settings_forms_nodereference_fields($node->type);
    $field = $settings['field'];
    $language = field_language('node', $node, 'body');
    $node->{$field}[$language][0]['nid'] = 408;
    $node->{$field}[$language][1]['nid'] = 408;
    $node->{$field}[$language][2]['nid'] = 408;
    node_save($node);
}

[field_event_form_s_] => Array
    (
        [und] => Array
            (
                [0] => Array
                    (
                        [nid] => 261
                    )

                [1] => Array
                    (
                        [nid] => 262
                    )

                [2] => Array
                    (
                        [nid] => 263
                    )
            )
    )

但是，每次尝试创建新节点时，都会出现以下错误：

PDOException:SQLSTATE[23000]：完整性约束冲突：1062键“PRIMARY”的重复条目“436”：插入到{node}（nid、vid、类型、语言、标题、uid、状态、创建、更改、注释、升级、粘贴、tnid、翻译）值中

我发现这是因为node_save函数，但没有它，我的更改不会提交

完整数组如下所示：

function myModule_node_insert($node){
    $settings = _settings_forms_nodereference_fields($node->type);
    $field = $settings['field'];
    $language = field_language('node', $node, 'body');
    $node->{$field}[$language][0]['nid'] = 408;
    $node->{$field}[$language][1]['nid'] = 408;
    $node->{$field}[$language][2]['nid'] = 408;
    node_save($node);
}

[field_event_form_s_] => Array
    (
        [und] => Array
            (
                [0] => Array
                    (
                        [nid] => 261
                    )

                [1] => Array
                    (
                        [nid] => 262
                    )

                [2] => Array
                    (
                        [nid] => 263
                    )
            )
    )

我在下一次谷歌搜索中发帖后立即找到了问题的答案。我认为它对其他人有用，包括我自己

下面的代码实现了这一点：

function myModule_node_insert($node){
    $settings = _settings_forms_nodereference_fields($node->type);
    $field = $settings['field'];
    $language = field_language('node', $node, 'body');
    $node->{$field}[$language][0]['nid'] = 408;
    $node->{$field}[$language][1]['nid'] = 408;
    $node->{$field}[$language][2]['nid'] = 408;
    field_attach_update('node', $node);
}

需要更新字段本身，而不是保存节点。盖伊在解释的时候做得更好，同时保持简单
