Rename Model(Table) in Django South Migration

When you change the name of model and create a migration file, you will see the code like “delete table, create table, and create relationship”.
It means you will lose all data in the previous model. However, here’s a simple way to rename model(table) with data.
Change the migration file as below or you may create yours.

class Migration(SchemaMigration):

    def forwards(self, orm):
        # Renaming model 'Tag' to 'RemarkTag'
        db.rename_table('meetings_tag','meetings_remarktag')

    def backwards(self, orm):
        # Renaming model 'Tag' to 'RemarkTag'
        db.rename_table('meetings_remarktag','meetings_tag')
