protected function baseQuery()
{
if (empty($this->baseQuery) && $this->parent->getData()) {
$through = $this->through;
$model = $this->model;
$alias = Loader::parseName(basename(str_replace('\\', '/', $model)));
$throughTable = $through::getTable();
//$this->model该换成$this->through
$pk = (new $this->model)->getPk();
$throughKey = $this->throughKey;
$modelTable = $this->parent->getTable();
$this->query->field($alias . '.*')->alias($alias)
->join($throughTable, $throughTable . '.' . $pk . '=' . $alias . '.' . $throughKey)
->join($modelTable, $modelTable . '.' . $this->localKey . '=' . $throughTable . '.' . $this->foreignKey)
->where($throughTable . '.' . $this->foreignKey, $this->parent->{$this->localKey});
$this->baseQuery = true;
}
} 最佳答案
