Module: SchemaPlus::ActiveRecord::SchemaDumper

Includes:
TSort
Defined in:
lib/schema_plus/active_record/schema_dumper.rb

Overview

SchemaPlus modifies ActiveRecord’s schema dumper to include foreign key constraints and views.

Additionally, index and foreign key constraint definitions are dumped inline in the create_table block. (This is done for elegance, but also because Sqlite3 does not allow foreign key constraints to be added to a table after it has been defined.)

The tables and views are dumped in alphabetical order, subject to topological sort constraints that a table must be dumped before any view that references it or table that has a foreign key constaint to it.
