使用对象元素作为参数的 Firestore 查询 [英] Firestore query using an object element as parameter

问题描述

我在一个项目中使用 Firestore 作为我的数据库，我有一个表，我需要在对象内进行查询

i'm using Firestore as my database in a project and i have a table that i need to do a query inside an object

{
   foo: "data",
   bar: "data",
   exObject: {
      dataToQuery: "value"
   }
}

这里是一个结构的例子，我想在对象内部进行查询一个看起来像这样的查询:

here is an example of a structure where i want to do a query inside the object a query that would look like this:

dbRef.collection("Table").where("exObject.dataToQuery", "==", "value")

但这不起作用.

有没有办法使用对象的内部值作为参数在 Firestore 中进行查询?如果没有，有没有办法实现相同的结果?

Is there a way to query in Firestore using an object's inner value as parameter? If not, is there a way to achieve something that would give the same result?

Firestore 结构示例

推荐答案

dbRef.collection("Table").where("exObject.dataToQuery", "==", "value")

我第一次发布的这个语法确实是很好的语法，并最终开始工作.我将我的问题的原因归类为一个错字，我必须尝试很多不同的事情来纠正

this syntax i first posted is indeed the good syntax and started working eventually. I'd class the reason of my problem as a typo that i must have corrected trying a lot of different things
