Varaible Validations

John Butler wrote:

I want to allow a user the ability to set certain values for validations via a table called settings. For example a model called loan can have a principal of between 2 values. In the settings table i have a field called max_loan_value and min_loan_value which i would like to be used for validating the amount entered for a loan calculation.

validates_inclusion_of :princiapl, :in=>setting.min_value..setting.max_value,:message => ": Loans between £100 and £12320 only"

Can anyone let me know if this is possible and point me in the right direction, ive looked about but cant seemt o find what i am looking for.

One way would be

def validate    unless (setting.min_value..setting.max_value) === princiapl      errors.add(:princiapl, ': Loans between £100 and £12320 only')    end end
