// Package migration enables you to generate migrations back and forth. It generates both migrations.

|
|
|
|
|
// //Creates a table
|
|
|
|
|
// m.CreateTable("tablename","InnoDB","utf8");

|
|
// Standard Column Methods
|
|
|
|
|
// * SetDataType
|
|
|
|
|
// * SetNullable
|
|
|
|
|
// * SetDefault
|

|
|
// * SetUnsigned (use only on integer types unless produces error)

|
|
|
// //Rename Columns , only use with Alter table, doesn't works with Create, prefix standard column methods with "Old" to
|
|
|
|
|
// //create a true reversible migration eg: SetOldDataType("DOUBLE(12,3)")
|
|
|
|
|
// m.RenameColumn("from","to")...

// //Foreign Columns, single columns are only supported, SetOnDelete & SetOnUpdate are available, call appropriately.
|

|
|
|
// //Supports standard column methods, automatic reverse.
|
|
|
|
|
// m.ForeignCol("local_col","foreign_col","foreign_table")
