 Geometric columns in your ActiveRecord models now appear just like
 any other column of other basic data types. They can also be dumped
 in ruby schema mode and loaded in migrations the same way as columns
 of basic types.

 Since this is a common case, it is the default. You have 2 ways to use
 the find_by_*geom_column*: Either by passing a geometric object directly,
 or passing an array with the 2 opposite corners of a bounding box
 (with 2 or 3 coordinates depending of the dimension of the data).
 
-  	Park.find_by_geom(LineString.from_coordinates([[1.4,5.6],[2.7,8.9],[1.6,5.6]]))
+        Park.find_by_geom(LineString.from_coordinates([[1.4,5.6],[2.7,8.9],[1.6,5.6]]))

-  	Park.find_by_geom([[3,5.6],[19.98,5.9]])
+        Park.find_by_geom([[3,5.6],[19.98,5.9]])
 
 In PostGIS, since you can only use operations with geometries with the same SRID, you can add a third element representing the SRID of the bounding box to the array. It is by default set to -1:
 
-  	Park.find_by_geom([[3,5.6],[19.98,5.9],123])

 It works for both MySQL and PostGIS (although the string returned
 is different for each database). You would use it like this, if
 the geometric column is a point:
 
     fixture:

-  	  data: HELLO
-  	  geom: <%= Point.from_x_y(123.5,321.9).to_yaml %>
