Method add​_constraint Add a constraint to a model.
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 alter​_field No summary
Method alter​_index​_together Deal with a model changing its index_together. The input index_togethers must be doubly-nested, not the single-nested ["foo", "bar"] format.
Method alter​_unique​_together Deal with a model changing its unique_together. The input unique_togethers must be doubly-nested, not the single-nested ["foo", "bar"] format.
Method create​_model Create a table and any accompanying indexes or unique constraints for the given model.
Method delete​_model Delete a model from the database.
Method execute Execute the given SQL statement, with optional parameters.
Method remove​_constraint Remove a constraint from a model.
