I am creating a rails application with geographical locations using spatial_adapter and GeoRuby. When running the actual application in development mode, everything works fine, but when trying to use YAML fixtures, I get a MySQL syntax error. I am using the following fixture:

one:
  name: Event One
  starts_at: 2011-04-20 12:00:00
  ends_at: 2011-04-20 16:00:00
  topics:
    - topic1
    - topic2
  pos: !ruby/object:Point
    x: 10
    y: 10

Running this, either with Test::Ruby or RSpec gives the following error:

ActiveRecord::StatementInvalid: Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds
to your MySQL server version for the right syntax to use near '), '2011-05-05 20:57:34', '2011-05-05 20:57:34', 908014535)'
at line 1: INSERT INTO `events` (`name`, `starts_at`, `ends_at`, `pos`, `created_at`, `updated_at`, `id`) VALUES ('Lindy Jam', '2011-04-20 12:00:00', '2011-04-20 16:00:00', GeomFromWKB(0x010100000000000000000024400000000000002440,), '2011-05-05 20:57:34', '2011-05-05 20:57:34', 908014535)

The key seems to be at this point:

GeomFromWKB(0x010100000000000000000024400000000000002440,),

With an extra comma inside the parenthesis. I don’t know where this is coming from, but it is working for regular insertions in the development-mode app.

The stack trace is:

    Turns out it’s an error in spatial_adapter. It expects there to be an srid attribute on the geometry objects, but for some reason one isn’t set when the fixtures create a GeoRuby object.

    A temporary workaround is to manually add an srid attribute in the YAML file like this:

    one:
  name: Event One
  starts_at: 2011-04-20 12:00:00
  ends_at: 2011-04-20 16:00:00
  topics:
    - topic1
    - topic2
  pos: !ruby/object:Point
    srid: -1
    x: 10
    y: 10

    Where -1 is just a placeholder for “unspecified srid”.
