Template Choices

gistfile1.txt

Something along these lines:

class SiteTemplate
    name - Business user "friendly" name
    path - The path to the actual template
    type - ('style', 'boutique')


class SiteTemplateContext
    """
    We use this to restrict template availability to only
    the contexts we want.
    """
    template - SiteTemplate
    context - SiteContext

On SiteContext, we add:
    default_boutique_template - SiteTemplate
    default_style_template - SiteTemplate

This lets us define the defaults at the SiteContext level, so conceivably the defaults for Toys R Us and Rue proper can be different.

On BoutiqueContext, we can add:
    boutique_template - SiteTemplate: this can be blank, in which case we use the default_boutique_template from SiteContext.
    default_style_template - SiteTemplate: this can also be blank, and we fall back to default_style_template from SiteContext.

StyleContext:
    style_template - SiteTemplate: nullable, falls back to above
