Since version 2.0.7 migration console provides a convenient way to create migrations.
If the migration name is of the form "create_xxx" or "drop_xxx" then a migration creating the table xxx with the columns listed will be generated. For example:
If the migration name is of a special form including but not limited to `create_xxx` or `drop_xxx` then migration
file would contain extra code when generated.
### Create Table

Similarly, you can generate a migration to drop table from the command line:

If the migration name is of the form "add_xxx_from_yyy" or "drop_xxx_from_yyy" then a migration containing the appropriate addColumn and dropColumn statements will be created.
### Add Column
If the migration name is of the form `add_xxx_to_yyy` then the file content would contain `addColumn` and `dropColumn`
