Rob,
I currently handle soft deletes (when required) using a delete() method on
my TO decorator. Say I have a an e-commerce catalog with categories and
items and categories are recursive. If a category has related items or
sub-categories, I want to soft delete. Here's the method to handle that:
<cffunction name="delete" hint="Delete the current instance"
returntype="void" output="false" access="public">
<cfscript>
if (isParent() || hasItem()) {
// enact soft delete
setIsDeleted(true);
getCatalogDao().save(this);
} else {
getCatalogDao().delete(this);
}
</cfscript>
</cffunction>
In my service, I would then use something along the line of.
<cffunction name="deleteCategory" returntype="void" output="false"
access="public">
<cfargument name="CategoryId" type="numeric" required="true">
<cfscript>
var category = getCategory(arguments.CategoryId);
category.delete();
</cfscript>
</cffunction>
I prefer this approach since it encapsulates the delete logic in the
business object.
