问题 I want to find events that are a on now and upcoming (next 30 days) but that are also not in the past. When i run this as a cloud function, I get "Cannot have inequality filters on multiple properties". How am I meant to get this type of data. (ignore the fact that the date stuff is a bit messy, am still playing around). // Create date 30 days in future const searchData: Date = new Date(); searchData.setDate(searchData.getDate() + 30); // Load data and handle empty respoonse const response:

问题 Stack: Ionic Nodejs/Express Cloud Firestore I am tasked with writing an app that takes dates in "day" format, with a balance for that day, and displaying that data in a chart using Chart.js. There are interval buttons that allow you to change between "day", "week", and "month" that is supposed to group the dates into respective intervals. This currently works fine using 1 collection. "days" and "weeks" both work, but once we get to "month" with large amounts of data Firestore kills itself in

问题 I am trying to figure out how to use a Firebase listener so that cloud firestore data is refreshed with react hooks updates.

问题 In my (greatly simplified) model I have users, accounts and account_types. Each user can have multiple accounts of each account_type. When an account of type TT is created I'm updating the "users" field of that object so it keeps the users which have accounts of that types, and the number of such accounts they have. users: { some fields }, accounts: { userID: UU, type: TT }, account_type: users: { UU: 31 } } I use the onCreate and onDelete cloud triggers for accounts to update the account
