我希望能够在提供where子句的同时保存数据。
我有以下代码：
$game = $this->Games->newEntity();
if ($this->request->is('post')) {
$game = $this->Games->patchEntity($game, $this->request->data);
if ($this->Games->save($game)) {
$this->Flash->success(__('The game has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The game could not be saved. Please, try again.'));
}
}
我尝试了这个，但它没有工作：
$this->Games->save($game)->innerJoinWith('Leagues', function ($q) use($s) {
return $q->where(['Leagues.user_id' => $s]);
}
)
我怀疑必须使用where子句进行查找并将请求数据修补到它？
$game = $this->Games->find()->innerJoinWith('Leagues', function ($q) {
return $q->where(['Leagues.user_id' => $this->Auth->user('id')]);
})
->where(['Games.id' => $id])
->first();
if(! count($game)){
$this->Flash->error(__('The game could not be found.'));
return $this->redirect(['action' => 'index']);
}
if ($this->request->is('post')) {
$game = $this->Games->patchEntity($game, $this->request->data);
if ($this->Games->save($game)) {
$this->Flash->success(__('The game has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The game could not be saved. Please, try again.'));
}
}
更简单吗？
答案 0 :(得分：1)
没有这样的保存语法，事先检索正确的实体是正确的方法，并且实际上并没有更简单的＆＃34;方式 - 但肯定有优化的空间。
就个人而言，我会使用查找程序来DRY进行操作，即在Medium.first.details上创建一个限制特定联盟用户的查找器：
GamesTable并在控制器动作中组合：
public function findForLeagueUser(\Cake\ORM\Query $query, array $options)
{
if (!isset($options['id'])) {
throw new \InvalidArgumentException('The `id` option is invalid or missing.');
}
return $query
->innerJoinWith('Leagues', function (\Cake\ORM\Query $query) use ($options) {
return $query->where([
$this->Leagues->aliasField('user_id') => $options['id']
]);
});
}
您也可以使用$game = $this->Games
->find('forLeagueUser', ['id' => $this->Auth->user('id')])
->where(['Games.id' => $id])
->first();
代替，如果找不到记录则抛出异常，这也是内部firstOrFail()所做的。
你可以通过为游戏ID使用动态查找器来进一步减少事情：
Table::get()另见
