使用 Laravel-Firebase 包更新 Firestore 文档及其 ID

Question

任何人都可以告诉我如何使用其 id 更新 firestore 文档吗？我可以使用 kreait 的 laravel-firebase 包创建一个文档并更新它。

我的下面的代码在 firestore 上创建文档。但是，如何使用文档引用或 ID 更新同一文档。

$groupsRef = app('firebase.firestore')->database()->collection('groups');

$groupData = [
                'groupAdmin'            => auth()->user()->id."_".auth()->user()->name,
                'groupDescription'      => $request->group_description,
                'groupIcon'             => $image,
                'groupId'               => '',
                'groupMembers'          => [
                    auth()->user()->id."_".auth()->user()->name
                ],
                'groupName'             => $request->group_name,
                'recentMessage'         => '',
                'recentMessageSender'   => '',
                'recentMessageTime'     => ''
            ];

            $groupsRef->add($groupData);

下面的实现使用其名称而不是其引用来更新文档。

$document  = $groupsRef->document($request->group_name);
$groupId = $document->id();

$updatedGroupData = [
            'groupAdmin'            => auth()->user()->id."_".auth()->user()->name,
            'groupDescription'      => $request->group_description,
            'groupIcon'             => $request->hasFile('groupIcon') ? $image : '',
            'groupId'               => $groupId,
            'groupMembers'          => [
                auth()->user()->id."_".auth()->user()->name
            ],
            'groupName'             => $request->group_name,
            'recentMessage'         => '',
            'recentMessageSender'   => '',
            'recentMessageTime'     =>  ''
        ];

        $updatedFitfam = $document->update($updatedGroupData);

Firestore add 返回文档引用，您可以从中获取文档 ID。然后更新如下：

$groupsRef = app('firebase.firestore')->database()->collection('groups');

$groupData = [
                'groupAdmin'            => auth()->user()->id."_".auth()->user()->name,
                'groupDescription'      => $request->group_description,
                'groupIcon'             => $image,
                'groupId'               => '',
                'groupMembers'          => [
                    auth()->user()->id."_".auth()->user()->name
                ],
                'groupName'             => $request->group_name,
                'recentMessage'         => '',
                'recentMessageSender'   => '',
                'recentMessageTime'     => ''
            ];

$docId = $groupsRef->add($groupData);


$updatedGroupData = [
            'groupAdmin'            => auth()->user()->id."_".auth()->user()->name,
            'groupDescription'      => $request->group_description,
            'groupIcon'             => $request->hasFile('groupIcon') ? $image : '',
            'groupId'               => $groupId,
            'groupMembers'          => [
                auth()->user()->id."_".auth()->user()->name
            ],
            'groupName'             => $request->group_name,
            'recentMessage'         => '',
            'recentMessageSender'   => '',
            'recentMessageTime'     =>  ''
        ];

        $updatedFitfam = $document->update($docId->id());

如果您想使用

$groupsRef

从

$request->group_name

获取文档，请使用以下解决方法：

$groupsRef = app('firebase.firestore')->database()->collection('groups');
$document = $groupsRef->document($request->group_name);
$snapshot = $document->get();

if ($snapshot->exists()) {
    $existingData = $snapshot->data();
    $updatedGroupData = [
        'groupAdmin'            => auth()->user()->id."_".auth()->user()->name,
        'groupDescription'      => $request->group_description,
        'groupIcon'             => $request->hasFile('groupIcon') ? $image : '',
        'groupMembers'          => array_merge(
            $existingData['groupMembers'] ?? [], 
            [auth()->user()->id."_".auth()->user()->name]
        ),
        'recentMessage'         => $existingData['recentMessage'] ?? ' ',
        'recentMessageSender'   => $existingData['recentMessageSender'] ?? ' ',
        'recentMessageTime'     => $existingData['recentMessageTime'] ?? ' '
    ];

    $document->update($updatedGroupData);
}
