问题 Does Firestore support something like whereNotEqual ? For example, I need to get exact documents where key "xyz" is missing. In Firebase realtime db, we could get it by calling *.equalTo(null) . Thanks. 回答1: Firestore does not support a direct equivalent of != . The supported query operators are <, <=, ==, >, or >= so there's no "whereNotEqual".

问题 I want to return an item with a specific ID and perform an update operation on it. My query gets the right result, but it won't let me update it. I tried following this tutorial: https://www.youtube.com/watch?v=mYyPbfpoZeM And read the documentation. Both didn't help. Other threads to the same topic are, well, different.

问题 I'm building a project with React & Redux & Firestore, I know how to delete/update/add etc.. But when I have 2 subcollections with dynamic field, I couldn't find any solution to delete it. If you look at the picture, I have the table ID and user ID, but the fields are 0, 1, 2 and so on. How can I delete a field from tableGuests? Maybe the structure is not good and could be better? guests > user id > userTables > table id > tableGuests which is an array. 回答1: How can I delete a field from
