Enhanced Option Types

Now supporting Spree 0.30.x !

Description

This extension enhances spree functionality when handling products with numerous and complex variants.

Following enhancements are provided:

• Admin side:
  • Selecting order of option types for prototype with drag & drop
  • Optional "modifiers" for option values that can modify price of variant
  • Option to generate set of variants from prototype with option types. When option is selected during product creation, variants are created for each combination of option values (eg. Sizes: [S,M,L], Colors: [Red, Blue] will generate 6 variants), with prices calculated from sum of product base price and amount of option_value modifiers.
  • Option to regenerate variants when needed.
  • Option to calculate variant price when creating new variant based on product price and sum of modifiers from option values.
• Client side variant selection:
  • using x select boxes (1 for each option_type)
  • using x sets of radio boxes grouped in fieldsets (one fieldset for each option type)
  • using 2d table of radio boxes (only when there are only 2 option types!)
• Javascript helpers:
  • Instant updating of price based on variant selected using above methods
  • Instant updating of number of on_hand units
  • enabling/disabling options that don't have corresponding variant.
  • products.js override (edge spree only) for working with variant images

Some of the functionality might not work without javascript, but much work was put to make JS as unintrusive as possible, so it should be fairly easy exercise to make it completely JS independent.

2d table was inspired by Stephanie Powell post You can(and should!) read it.

Examples

On first example you can see sets of radio boxes and modifiers in action, also notable is separation of base price and current(variant) price, only second one is updatable.

Second one shows selects - it's much more compact then previous example, but doesn't instantly show all options.

Thrid shows the 2d table for variant choosing.

Installation

Add the following to your Gemfile: gem 'spree_enhanced_option_types', :git => 'https://github.com/swistak/spree-enhanced-option-types.git'

Run: bundle install

and: rake spree_enhance_option_types:install

and finally: rake db:migrate

Customization

User interface change is limited only to _cart_form partial from original spree. it was separated into several subfiles to make customization and embedding in custom layouts easier.

There are no inline styles (except for 2d table, that absolutely requires some wire frame styles to look sane), you can either use provided _cart_form partial as a replacement for generic spree partial, or you can roll your own and only include one of variant choosing partials.

There are some special css classes you might be interested in: .price.update - price field that should be updated with new price value if variant changes. span.

Source is extensively documented and I recommend reading it.

Limitations

• currently there's no way to change order of option types AFTER product is created

TODO

• graceful handling non-js users.
• test under other browsers then FF
