Rails -- validations

Question

I know that the validates method can validate presence, length, format, uniqueness, and confirmation. However, sometimes I see people just setting these values to true/false, while other times they are more specific and pass in a hash that specifies the exact constraints (e.g. :maximum => 50 for length or case_sensitive => false for uniqueness). Is there a way that I can view a list of all the specifications that can be added to each of these validation tests?

This is right in the Rails API for ActiveModel::Validations::HelperMethods.

A list of validators and their respective options can be found here: http://api.rubyonrails.org/classes/ActiveModel/Validations/HelperMethods.html
