When do I know GeoFire is finished loading as it is Event based trigger

由 半世苍凉 提交于 2019-12-02 08:34:03
So I used GeoFire and AngularFire for populate my ng-repeat item lists. There is an ionic pull to refresh list. So user pull it and get the current updated location and refresh the list (recall the GeoFire to re-populate the list). $scope.doRefresh = function() { if ($scope.doneLoading) { $scope.useCurrentLocation().then(function() { $scope.userCurrentLocation = { lat: geoLocation.getGeolocation().lat, lng: geoLocation.getGeolocation().lng } angular.forEach($scope.tasks, function(child) { child.$destroy(); }); setupTaskListing(); $scope.$broadcast('scroll.refreshComplete'); }) } } function

How To Display Multiple Markers Coordinates Stored In Firebase Database On Google Maps

由 好久不见. 提交于 2019-12-02 07:49:05
I am trying to get the coordinates that are saved in the firebase real-time database and display them on a map using the google maps API. This is the code I have so far. Right now it opens and shows the users current location using the html5 geolocation API and it syncs the lat and long coordinates to the firebase real-time database using Geofire. I don't know how to retrieve these points and have multiple points on the google map at the same time showing different users locations. If anyone could help me with this I would really appreciate it. <script src="https://cdn.firebase.com/libs

Using GeoFire queries in Swift does not give useful output

I'm pretty desperate right now because I'm trying to use GeoFire on my Firebase Database to find nearby users. I'm pretty much stuck for two days now. I searched Google and stackoverflow a lot and tried everything I found there but without any success. Now my last hope is to create this thread myself and hope someone can help me. My database pretty much looks like this: users user_id1 email: xxx@gmail.com username: xxx user_id2 email: yyy@gmail.com username: yyy users_locations user_id1 location g: xxxx l 0: 30.0000 1: 5.0000 user_id2 location g: yyyy l 0: 30.0010 1: 5.0010 I don't know if it

How to remove a GeoFire handle for the following observe in Swift?

由 纵然是瞬间 提交于 2019-12-01 14:10:09
This is a question for Swift, Firebase and Geofire. I would like to know how to remove a GeoFire handle for the following observer in Swift. locationsEnd!.query(at: location, withRadius: 16.0).observe(GFEventType.init(rawValue: 0)!, with: {(key, location) in The following works fine (in viewDidDisappear): locationsEnd?.firebaseRef.removeAllObservers() However with handle it does not: var locationHandle: UInt = 0 override func viewDidDisappear(_ animated: Bool) { super.viewDidDisappear(animated) //following does not work: locationsEnd?.firebaseRef.removeObserver(withHandle: locationHandle) }

Firebase/GeoFire - Most popular item at location

由 ≯℡__Kan透↙ 提交于 2019-12-01 14:06:36
I am currently in the evaluation process for a database that should serve as a backend for a mobile application. Right now I am looking at Firebase , and for now I like it really much. It is a requirement to have the possibility to fetch the most popular items at a certain location (possibly in the future: additionally for a certain time range that would be an attribute of the item) from the database. So naturally I stumbled upon GeoFire that provides location based query possibilities for Firebase. Unfortunately - at least as far as I understood - there is no possibility to order the results

Limit the number of queried items from GeoFire

问题 I have a lot of entry in the same location. I would like only to get the 10 latest added items using Geofire. I know that it can be done easily with firebase using Query.limitToLast() but I don't know how to do it with Geofire. If it is not possible, do you have any workaround that I can apply ? 回答1: There is only one solution for this : you should begin a query with a small radius, and each time you reach onGeoQueryReady() ("All data has been loaded"), you increase the radius by a small
