This module enables a property in a DataMapper::Resource class to be filtered on save into another property, using per-row and/or per-property filters.
To use in a model:
include Filters::Resource
The syntax when defining a property is:
property :prop_name, :filter => {
:to => :filtered_prop,
:with => :filter_column,
:default => "DefaultFilter"
}
(:with and :default are optional, though at least one should be specified.)
See Filters::AVAILABLE_FILTERS for some filter options. Additional filters may be defined in this constant Hash.
If the properties in :to and :with have not yet been defined, they will be defined automatically. Hence, if want to specify any options with this, they should be defined before to filtered property.
