Is there a way to only add an error, if multiple validations fail?-CodePudding

I am a beginner at ruby on rails. I am trying to add an error, only if multiple validations fail.

My initial idea is to use multiple unless with or operator.

class SomeValidator
  def validate(record)
    unless code.match(some_regex) || code.match(some_other_regex) || code.match(some_other_regex) 
      add error
    end
  end
end

it just doesn't seem right.

If I validate each validation separated, the validation will fail before the next one.

I don't know if it is clear, I want to see a way to for example, validate a string to four different regexes, and add an error if all four regexes fail.

CodePudding user response：

If you want to only execute some piece of logic if all four conditions fail, you'll want to use && (logical and) and not || (logical or)

CodePudding user response：

You could use Array#none? it should return true if all elements are false. for example:

add error if [condition_1, condition_2, condition_3].none?

Or as mentioned by @inyl

add error unless condition_1 && condition_2 && condition_3

unless is confusing, I would avoid it for complex conditions.
