Add 'withinPolygon' to ParseQuery

[tarekskr]

In addition to the existing 'ParseQuery.withinGeoBox', we also need a 'withinPolygon' function so that we could search inside a polygon of GeoPoints.

AFAIK, this is supported by MongoDB, but I have no idea how to implement it myself in Parse :)

Here is the MongoDB documentation: https://docs.mongodb.com/manual/reference/operator/query/polygon/#op._S_polygon

I am also in need of this feature. Unfortunately AFAIK, previous pull requests have been denied citing the need to be compatible with the Parse.com legacy database, which runs an older, non-geojson compatible version of MongoDB.

I believe this is actually a good feature to have.

Recently, the Parse Server Evolution repo was created to manage better feature requests.

@tarekskr do you think you can add a PR there with the proposal? Fork the repo, add a new proposal according to this template to the proposals folder, and create the PR.

@natanrolnik I am not that familiar with github, but if you guys could do it please feel free to copy the request and make it your own. Many thanks!

Alright, I've created a pull request with the feature request. Please let me know if I missed something.

Hey @madsb does this add support for geoJSON/2dsphere location queries? That would be a quantum leap for location based applications

[madsb]

@otymartin At the moment it's just a feature request, but I agree completely! Hopefully someone with the right coding chops will take a stab at it. Well, at least as soon as the pull request is merged (hint-hint, @flovilmart ;) ).

@madsb
Question & maybe is just my lack of knowledge on the subject but shouldnt it still be technically possible to associate PFObjects with a geoJSON property and use cloud code to perform 2dsphere queries. As I understand these are capabilities existing with mongoDB independent of parse server or does parse-server/parse-iOS SDK need to add some kind of support for it?

Added in Parse Server 2.5.0. Closes via #3866
