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: admin.firestore.QuerySnapshot = await admin
.firestore()
.collection(Collections.EVENTS)
.where("startDate", "<=", admin.firestore.Timestamp.fromMillis(searchData.valueOf()))
.where("endDate", ">=", admin.firestore.Timestamp.fromMillis(new Date().valueOf()))
.where("public", "==", true)
.limit(NUMBER_OF_EVENTS)
.get();
Edit: I would like to know the data structure/query method that will allow me to return all events in the events collection that are on now or that will start in the next month. Additionally, I would like the query to exclude events that have already finished. Each document (event) has a startDate and endDate timestamp on it.
Since you have two fields to check with ranges, I'm not sure this is doable with a single query. What you can do instead is perform two queries, merge the results on the client, and perform a final filter to get the exact matches.
I can't think of a way to structure your data that will do this with a single query.
From the docs:
You can only perform range comparisons (<, <=, >, >=) on a single field, and you can include at most one array-contains or array-contains-any clause in a compound query:
citiesRef.where("state", ">=", "CA").where("state", "<=", "IN");
citiesRef.where("state", "==", "CA").where("population", ">", 1000000);

I know this is kind a old thread, but the answer might be good for others.
What you can do as I at the end ended up doing, is that you have a $start_date and a $target_date.
You then do like this:
<?php
$start = strtotime('2021-11-22');
$target = strtotime('2022-01-01 0:00:00');
$limit = (($target - $start) / 86400);
$query = $col_data->where('date.day_start', '>=', $start);
$query = $query->limit($limit);
?>
Not bad, eh? You welcome!
