Hey all, I'm trying to integrate SimpleForm's validation reflection with
DataMapper and I've hit a tiny wall.
Basically I am trying to get the dm equivalent of this ActiveRecord method:
Person.validators_on(:name)
And that is proving to be a challenge because in datamapper all we get is
the validators method, a class which contains an array of validations:
*Person.validators*
*=> #<DataMapper::Validations::ContextualValidators:0x0000010204e360
@contexts={:default=>[...validations here...]*
I can access that array like this: *Site.validators.contexts[:default]*
But as far as accessing all validations for a given attribute, I'm plain
stumped. Maybe if it was a hash I could pull it off by accessing keys, but
since it's an array I am at a loss as to how I can query for the relevant
validations.
Any ideas? Is there an easier method for doing this that I've missed?
