instance method
added?
Ruby on Rails edge
Since v3.2.22.5Signature
added?(attribute, type = :invalid, options = {})Returns true if an error matches provided attribute and type,
or `false` otherwise. `type` is treated the same as for `add`.
```
person.errors.add :name, :blank
person.errors.added? :name, :blank # => true
person.errors.added? :name, "can't be blank" # => true
```
If the error requires options, then it returns `true` with
the correct options, or `false` with incorrect or missing options.
```
person.errors.add :name, :too_long, count: 25
person.errors.added? :name, :too_long, count: 25 # => true
person.errors.added? :name, "is too long (maximum is 25 characters)" # => true
person.errors.added? :name, :too_long, count: 24 # => false
person.errors.added? :name, :too_long # => false
person.errors.added? :name, "is too long" # => false
```: (Symbol | String, ?untyped, ?untyped) -> bool
