Runs all the validations within the specified context. Returns true if no errors are found, false otherwise.
If the argument is false (default is nil
), the context is set to :create
if new_record?
is true, and to :update
if it is not.
Validations
with no :on
option will run no matter the context. Validations
with some :on
option will only run in the specified context.
