Instance Method Details

#call(object) ⇒ nil, { <Symbol, ::Number> => { Symbol => Object } }

Validate the object.

It should return nil, if object is valid and a hash with the errors otherwise. The hash keys should be selectors of the errorneous objects, while the values should be lists of symbols identifying failed validations and their parameters.

A selector in this context is a path through the object hierarchy. For example the path of the number 5 in

v = { array: [1, 3, 5] }

would be [:array, 2], because v.fetch(:array).fetch(2) is 5.

So a validation, that validates, that the object at the position of 5 is larger than 6, should, for example, return

{ [:array, 2] => [[:greather_than, { min: 6 }]] }

Parameters:

  • object (Object) —

    to be validated

Returns:

  • (nil) —

    if object is valid

  • ({ <Symbol, ::Number> => { Symbol => Object } }) —

    if there were errors
