我想保存多边形。
这是Geojson enter link description here
str1 = "geojson....."
geom = RGeo::GeoJSON.decode(str1, json_parser: :json)
l = Limit.new
l.multipoligono = geom
l.save
NoMethodError: undefined methodfactory' for #RGeo::GeoJSON::FeatureCollection:0x3fc7febb7424`
这是我的rgeo.rb
RGeo::ActiveRecord::SpatialFactoryStore.instance.tap do |config|
config.default = RGeo::Geos.factory_generator
config.register(RGeo::Geographic.spherical_factory(srid: 4326), geo_type: "point")
config.register(RGeo::Geographic.spherical_factory(srid: 4326), geo_type: "multi_polygon")
config.register(RGeo::Geographic.spherical_factory(srid: 4326), geo_type: "geometry_collection")
end
答案 0 :(得分:2)
有110颗星,我想this is how they do it in ruby。
hash = RGeo::GeoJSON.encode(feature)
hash.to_json == str2 # => true
那就是说,我不会这样做。我也不会使用Ruby。查看PostGIS的ST_AsGeoJSON
。它返回geojson的特征部分。也就是说,将RGeo从等式中删除。
