Method __init__ Undocumented
Method ​_create​_spatial​_index​_name Undocumented
Method add​_field Create a field on a model. Usually involves adding a column, but may involve adding a table instead (for M2M fields).
Method column​_sql Return the column definition for a field. The field must already have had set_attributes_from_name() called.
Method create​_model Create a table and any accompanying indexes or unique constraints for the given model.
Method create​_spatial​_indexes Undocumented
Method remove​_field Remove a field from a model. Usually involves deleting a column, but for M2Ms may involve deleting a table.
Method skip​_default Some backends don't accept default values for certain columns types (i.e. MySQL longtext and longblob).

Inherited from DatabaseSchemaEditor:

Method ​_alter​_column​_type​_sql Hook to specialize column type alteration for different backends, for cases when a creation type is different to an alteration type (e.g. SERIAL in PostgreSQL, PostGIS fields).
