Instance Method Detail

def columns : Array(Marten::DB::Management::Column::Base) #

[View source]
def describe : String #
Description copied from class Marten::DB::Migration::Operation::Base

Returns a human-friendly description of what the operation is doing.

def indexes : Array(Marten::DB::Management::Index) #

def mutate_db_backward(app_label : String, schema_editor : Management::SchemaEditor::Base, from_state : Management::ProjectState, to_state : Management::ProjectState) : Nil #
Description copied from class Marten::DB::Migration::Operation::Base

Applies the operation in a backward way at the database level.

For most operation, this will involve "unapplying" whatever was done as part of the #mutate_db_forward method.

def mutate_db_forward(app_label : String, schema_editor : Management::SchemaEditor::Base, from_state : Management::ProjectState, to_state : Management::ProjectState) : Nil #
Description copied from class Marten::DB::Migration::Operation::Base

Applies the operation at the database level.


[View source]
def mutate_state_forward(app_label : String, state : Management::ProjectState) : Nil #
Description copied from class Marten::DB::Migration::Operation::Base

Applies the operation at the project state level.


[View source]
def name : String #

[View source]
def optimize(operation : Base) : Optimization::Result #
Description copied from class Marten::DB::Migration::Operation::Base

Combines the specified operation with the current one and return an array of corresponding operations.


[View source]
def references_column?(other_table_name : String, other_column_name : String) : Bool #
Description copied from class Marten::DB::Migration::Operation::Base

Returns true if the operation references the specified table column.


[View source]
def references_table?(other_table_name : String) : Bool #
Description copied from class Marten::DB::Migration::Operation::Base

Returns true if the operation references the specified table.


[View source]
def serialize : String #
Description copied from class Marten::DB::Migration::Operation::Base

Renders a serialized version of the mutation.

This method is used when generating migrations: the serialized operation is inserted in the #plan method of the generated migration.
