SpreeFlexiVariants

This is a spree extension that solves two use cases related to variants. I call them Ad Hoc Options and Product Customizations.

Ad Hoc Options

Use these when have numerous (possibly price-altering) product options and you don't want to create variants for each combination.

You can also restrict certain combinations of options from coexisting. These are called Ad Hoc Exclusions and are described in more detail in the wiki.

Product Customizations

Use these when you want the ability to provide a highly customized product e.g. "Cut to length 5.82cm", "Engrave 'thanks for the memories'", "Upload my image". Full control over pricing is provided by the Spree calculator mechanism.

Version Notes

The branch you are currently on (master) is an upgrade-in-progress to spree 1.0. Consider it beta right now.

Please see the Versionfile for working spree 0.70 and spree 0.60 versions

Version 2

I'm excited to announce that I'm working feverishly on a complete rewrite (currently in the v2 branch (and highly pre-alpha), if you are curious).

After using this extension in a few projects, I discovered some areas for improvement.

The goal with the next version is to:

  • Allow the extension to play nicely with all other extensions.

The current version does major surgery on (and changes the parameters of) Order#add_variant. This interferes with some other extensions. Version 2 will be far less intrusive on the existing spree models

  • Keep the notion of a variant.

The current version does not allow you to later look up the variant and be able to reconstruct its state. This is all at the LineItem level now.

  • Allow more advanced pricing (dependent options, etc.)

  • Allow skus to be computed based on the selected options

  • Less cumbersome traversing of the object graph.

  • Better image customization support

  • Fewer new models!

Many, many thanks to Brian Quinn for selflessly volunteering his time to mentor me throughout the development process.
