First step to close: #1559
Solution
Were added two mechanisms to treat
validate_length_of_matcherrelated attribute as array. One was througharray_column?helper(also used onvalidate_absence_of_matcher) based on column type ifarray?helper is defined on model'scolumns_hashand another one with an explicit chain methodas_arraythat will force to validate column with arrays values.Why this way? First one will cover pure
array: truecolumns for postgresql, second one could be dynamically used to check, for example, json columns storing arrays and being treated like that. This second approach will leave more freedom when using the validator.Main validate_length_of_matcher specs were duplicated for the two variants. After all review's iteration for this PR concluded and if it's finally approved and merged this approach, I'll continue extending the array support to other validators(as inclusion/exclusion).
