Instance Method Summary
-
#default : String?
Returns the default value of the field if any.
-
#empty_value?(value) : ::Bool
Returns
true
if the value is considered empty by the field. -
#from_db(value) : ::String | Nil
Converts the raw DB value to the corresponding field value.
-
#from_db_result_set(result_set : ::DB::ResultSet) : ::String | Nil
Extracts the field value from a DB result set and returns the right object corresponding to this value.
- #max_size : Int32?
-
#to_column : Management::Column::Base | Nil
Returns a migration column object corresponding to the field at hand.
-
#to_db(value) : ::DB::Any
Converts the field value to the corresponding DB value.
-
#validate(record, value)
Runs custom validation logic for a specific model field and model object.
