# Gadget Some methods for getting metadata and other deep details from a PostgreSQL database. ## Installation Add this line to your application's Gemfile: gem 'gadget' And then execute: $ bundle Or install it yourself as: $ gem install gadget ## Usage `#tables(conn)` Returns a list of all tables in the schema reachable through `conn`. `#columns(conn, tablename=nil)` Returns a list of all columns in the schema reachable through `conn`. If `tablename` is given, returns the columns in only that table. `#foreign_keys(conn, tablename=nil)` Returns a list of all foreign keys in the schema reachable through `conn`. If `tablename` is given, returns the foreign keys in only that table. `#constraints(conn, tablename=nil)` Returns a list of all constraints in the schema reachable through `conn`. If `tablename` is given, returns the constraints in only that table. `#dependencies(conn)` Returns a structure representing the dependencies between tables in the schema reachable through `conn`. Table A is defined as dependent on table B if A contains a foreign key reference to B. `#tables_in_dependency_order(conn)` Returns a list of all tables in the schema reachable through `conn`, ordered such that any given table appears later in the list than all of its dependencies. `#dependency_graph(conn)` Returns `.dot` script (suitable for feeding into Graphviz) describing the table dependency graph. `#functions(conn)` Returns a list of all functions in the schema reachable through `conn`. `#sequences(conn)` Returns a list of all sequences in the schema reachable through `conn`. `#triggers(conn)` Returns a list of all triggers in the schema reachable through `conn`. `#types(conn)` Returns a list of all types in the schema reachable through `conn`. ## Contributing 1.
