2番目のフィードが最初のフィードからノードを更新できるようにする何かを一緒にノックしました。これが正しいやり方かどうかはわかりませんが、機能します。これが将来誰かを助ける場合に備えて私がしたことです:
- FeedsNodeProcessorを拡張するカスタムプロセッサを作成しました
- FeedsNodeProcessorのすべての関数を新しいクラスにコピーしました。
- 既存のEntityId関数を次のようにオーバーライドしました(harvard_formatは私のセカンダリフィードであり、pure_feedは私のプライマリフィードです):
保護された関数existingEntityId(FeedsSource $ source、FeedsParserResult $ result){
if($source->id == 'harvard_format') {
$query = db_select('feeds_item')
->fields('feeds_item', array('entity_id'))
->condition('feed_nid', $source->feed_nid)
->condition('entity_type', $this->entityType())
->condition('id', 'pure_feed');
// Iterate through all unique targets and test whether they do already
// exist in the database.
foreach ($this->uniqueTargets($source, $result) as $target => $value) {
switch ($target) {
case 'url':
$entity_id = $query->condition('url', $value)->execute()->fetchField();
break;
case 'guid':
$entity_id = $query->condition('guid', $value)->execute()->fetchField();
break;
}
if (isset($entity_id)) {
// Return with the content id found.
return $entity_id;
}
}
return 0;
}
elseif ($nid = parent::existingEntityId($source, $result)) {
return $nid;
} else {
// Iterate through all unique targets and test whether they do already
// exist in the database.
foreach ($this->uniqueTargets($source, $result) as $target => $value) {
switch ($target) {
case 'nid':
$nid = db_query("SELECT nid FROM {node} WHERE nid = :nid", array(':nid' => $value))->fetchField();
break;
case 'title':
$nid = db_query("SELECT nid FROM {node} WHERE title = :title AND type = :type", array(':title' => $value, ':type' => $this->config['content_type']))->fetchField();
break;
case 'feeds_source':
if ($id = feeds_get_importer_id($this->config['content_type'])) {
$nid = db_query("SELECT fs.feed_nid FROM {node} n JOIN {feeds_source} fs ON n.nid = fs.feed_nid WHERE fs.id = :id AND fs.source = :source", array(':id' => $id, ':source' => $value))->fetchField();
}
break;
}
if ($nid) {
// Return with the first nid found.
return $nid;
}
}
return 0;
}
}
- FeedsProcessorからProcess関数とnewItemInfo関数にコピーされます。
- newItemInfoを次のようにオーバーライドしました。
保護された関数newItemInfo($ entity、$ feed_nid、$ hash =''){
$entity->feeds_item = new stdClass();
$entity->feeds_item->entity_id = 0;
$entity->feeds_item->entity_type = $this->entityType();
// Specify the feed id, otherwise pure_feed's entries in the feeds_item table will be changed to harvard_format
$entity->feeds_item->id = ($this->id == "harvard_format") ? "pure_feed" : $this->id;
$entity->feeds_item->feed_nid = $feed_nid;
$entity->feeds_item->imported = REQUEST_TIME;
$entity->feeds_item->hash = $hash;
$entity->feeds_item->url = '';
$entity->feeds_item->guid = '';
}
