多边形内的Mongodb点未获得结果-Mongoid+；轨道

我试图用mongodb（mongodb 2.6）检查一个点是否在多边形内。 我在反收集中插入数据，如下所示：

db.areas.insert({"polygons":
                      {"type":"Polygon",
                         coordinates:
                          [[[-23.0651232, -45.6374645],
                            [-23.0557255, -45.6435585],
                            [-23.0370072, -45.6383228],
                            [-23.0299772, -45.6351471],
                            [-23.0025649, -45.6480217],
                            [-22.9723022, -45.6554031],
                            [-22.9340493, -45.6032181],
                            [-22.9353140, -45.5925751],
                            [-22.9383177, -45.5855370],
                            [-22.9601320, -45.5560112],
                            [-22.9645577, -45.5597878],
                            [-22.9938740, -45.5675125],
                            [-22.9939530, -45.5690575],
                            [-23.0217620, -45.5712891],
                            [-23.0241319, -45.5719757],
                            [-23.0258697, -45.5711174],
                            [-23.0268966, -45.5721474],
                            [-23.0656365, -45.6372499],
                            [-23.0651232, -45.6374645]
                        ]]
                      }
                 });

db.areas.find({polygons:
                 {$geoIntersects:
                     {$geometry:{ "type" : "Point",
                          "coordinates" : [ -22.112, -45.56 ] }
                      }
                  }
             });

像这样询问：

db.areas.insert({"polygons":
                      {"type":"Polygon",
                         coordinates:
                          [[[-23.0651232, -45.6374645],
                            [-23.0557255, -45.6435585],
                            [-23.0370072, -45.6383228],
                            [-23.0299772, -45.6351471],
                            [-23.0025649, -45.6480217],
                            [-22.9723022, -45.6554031],
                            [-22.9340493, -45.6032181],
                            [-22.9353140, -45.5925751],
                            [-22.9383177, -45.5855370],
                            [-22.9601320, -45.5560112],
                            [-22.9645577, -45.5597878],
                            [-22.9938740, -45.5675125],
                            [-22.9939530, -45.5690575],
                            [-23.0217620, -45.5712891],
                            [-23.0241319, -45.5719757],
                            [-23.0258697, -45.5711174],
                            [-23.0268966, -45.5721474],
                            [-23.0656365, -45.6372499],
                            [-23.0651232, -45.6374645]
                        ]]
                      }
                 });

db.areas.find({polygons:
                 {$geoIntersects:
                     {$geometry:{ "type" : "Point",
                          "coordinates" : [ -22.112, -45.56 ] }
                      }
                  }
             });

但我没有结果。有什么想法吗

我查看了以下链接：

任何帮助都将不胜感激

我找到了答案。 问题是，当我试图保存时，Rails表单中多边形的坐标保存为字符串，而不是双精度。 在保存之前，我发现问题已经解决了。
