Question

我正在尝试更新Firestore文档中的两个字段，但是显示了错误，我不确定为什么该错误指出当文档中有数据时找不到文档。数据来自上一个活动。该文档已在上一个活动中添加到数据库中。如何解决这个问题呢？谢谢你。

Answer 1

错误消息表明您正在尝试使用ID为“ 0M0F1Ug5TmcO3pV”的此文档进行访问：

main/0M0F1Ug5TmcO3pVaZu4XMluGOty1/journal/0M0F1Ug5TmcO3pV

但是您的屏幕快照显示的是另一个以“ v91fz”开头的文档。正如错误消息所述，错误消息中的文档根本不存在。

您的文档具有名为“ id”的字段这一事实并不意味着任何事情。列中显示的文档ID和其他所有文档ID才是更新的重要内容。

我认为您犯了一个错误，因为用户ID与实际的文档ID不同。您可以使用add（）创建文档，该文档分配一个随机ID（而不是用户ID）。也许您想实际使用用户ID而不是随机ID来创建文档。只是现在还不清楚您的意图，但是错误消息是正确的。

由于您要传递对象：

        xmlns:fo="http://www.w3.org/1999/XSL/Format"

        </xsl:variable> 

<xsl:apply-templates select="exsl:node-set($content)"/>     
</xsl:template>

</xsl:stylesheet>

我希望您的autopep8 -i <filename>.py类实现intent.putExtra("journal", journal);，这意味着：

Journal

更新

您没有在文档字段Serializable中输入正确的ID

执行此操作：

//your class must implement Serializable

class Journal implements Serializable{

..........

}

在下一个活动中，同时获取对象和documentID：

id

///当您更新文档时使用documentID

......
......

journal = new Journal(userId, title, descText, date, advice, answer, question, detectedScoreText, sentencesToneText);

 userIdRef.add(journal).addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
@Override
public void onSuccess(DocumentReference documentReference) {

//get the reference of the document like this:
String documentID = documentReference.getId();

Intent intent = new Intent(AddNoteActivity.this, ReceivedActivity.class);
intent.putExtra("journal", journal);
//send it along with the object
intent.putExtra("documentID", documentID);
startActivity(intent);
finish();
.......
......
