Rails I18n: How to add a error translation key which is common for all model base errors? -

in current application use i18n. have add :base error key should common models. ex: add :common_error in 1 place in en.yml file , use follows,

@user.errors.add(:base, :common_error) @post.errors.add(:base, :common_error) ..and on 

i'm worried if should add :common_error key in models there more model present in application.

my current en.yml file looks follows,

en-uk:   activerecord:     errors:       <<: *errors         models:           user:             attributes:               base:                 some_key: ""           post:             attributes:               base:                 some_key: "" 

i'm not sure if there simple solution haven't found. ideas appriciated. in advance!

simply don't use relative translation key -

@user.errors.add(:base, t(:common_error) ) 

if pass symbol errors.add translation uses scope of model.
