arunsark / broken_record Goto Github PK

This is meant to be a demo program for Practicing Ruby. It is not suitable for any real purpose. However, it may be a fun starting point for palying around with design strategies for implementing object-relational mappers.

The most interesting thing about this codebase is that it attempts to implement a design that is not heavily dependent on class inheritance and module mixins. In fact, the only mixin used is BrokenRecord::Composable, which facilitates a composition-based, object-oriented alternative to mixins. It is probably a bad idea for a number of reasons, but is worth investigating.

To run the examples for this program, do the following:

1. Run bundle or manually install the sqlite3 gem

2. Run any example in the examples/ folder

Broken Record itself does not have a hard dependency on the sqlite3 gem, but does use SQLITE3 syntax exclusively. Its examples and tests use an in-memory database, so you don't need to configure anything to try them out as long as you have the dependencies installed. The examples will obviously make a lot more sense if you've read Practicing Ruby issues 4.8 and 4.10, but if you just stumbled across this repository by chance and have questions, feel free to email [email protected] with questions.

Enjoy!!!
