# Custom types are scoped to a particular site instance, | |
# so their class names are suffixed with the site ID. | |
# This also helps Content#const_missing figure out when we're | |
# trying to load a custom type, because it gets numbers at the | |
# end of the class name. | |
# Note: I've put some validation logic in CustomType to ensure | |
# that the name in the database is a valid Ruby constant name. | |
# new_custom_type = Content::CustomType.create(:site_id => 1, :name => "My custom type") | |
# Content::MyCustomType1 #=> Content::MyCustomType1(...) | |
