Hyrule: Min vs Size

I just wanted to throw out a quick question to anyone still actually reading this blog ;) I am working on updating my Hyrule Validation framework and I came across an interesting scenario. I never supported rules on collections so I am struggling with what I should do here.

Say we have a product class and a product has a collection of categories. The product could have one category or it could belong to many. I have a @Min constraint which I use for things like string lengths, numbers and dates. It just seems strange to place a min constraint on a collection. For collections I have a size constraint. It will allow you to pass the size min and max in the form of n..n where n is a valid number or -1 for no max. In the example we talked about earlier I could do something like this. It just seems weird to support collections with the @Min constraint, what are your thoughts? component persistent="true" { property name="id" column="product_id" fieldtype="id" generator="native"; /** * @blank false */ property name="name"; /** * @blank false */ property name="description" ormtype="text"; /** * @size 1..-1 */ property name="categories" fieldtype="many-to-many" cfc="hyrule.samples.advancedorm.model.category.Category" linktable="product_categories" fkcolumn="product_id" inversejoincolumn="category_id" lazy="true" cascade="all" singularname="category"; public Product function init(){ setCategories([]); return this; } }
