Rails: calling standard validations from a custom validator -


is there way call standard rails validators within custom validator?

i have combination of oauth/email signup/sign in , want able call validators on each method of authentication. instance, want able call validates_uniqueness_of :email if user signs through email , call single validator, instance validates_with uservalidator.

if there isn't way i'm going use state tracking , series of :if validations.

i believe there's no way call other validators custom one, may possibly cause circular dependency dangerous.

you have go conditional validations, keep in mind can scope them (taken rails guides)

with_options if: :is_admin? |admin|   admin.validates :password, length: { minimum: 10 }   admin.validates :email, presence: true end
