[Answer]-Django 1.4.5 – Failed to install index for WorldBorder model

Creating spatial indexes returns an error if the data base type is not myisam:

ERROR 1464 (HY000): The used table type doesn’t support SPATIAL indexes

You can change the database type to myisam and this example will work by doing the following:

alter table geom engine=myisam;
