get validations from model


How cat I get list of validations defined in model

Example:

class ModelName
  validates_presence_of :field_name
  validates_inclusion_of :sex, :in => %w(M F)
end

I need Hash like:

{:field_name => 'required', :sex => 'Must be in: M, F'}

Solution

  • You don't need a plugin for basic needs.

    You can do this to get a hash of all validators.

    ModelName.validators
    

    If you want to get the validators for a specific field :

    ModelName.validators_on(:attribute)
