Instance Method Details

#call(fn, failure:, success:) ⇒ Object

Execute ‘fn` within an `ActiveRecord` transaction.

Rough types: “‘

fn

void -> ReturnValue

failure

value -> NilClass

success

value -> NilClass

# or

success

void -> NilClass

“‘

If ‘fn` returns an `ErrorValue`, roll back the transaction and call `failure` with the unwrapped error `value`. Otherwise commit the transaction and call success.

def call(fn, failure:, success:)
  error = nil
  result = nil

  ActiveRecord::Base.transaction do
    result = fn.call

    if Hopscotch::Error.error?(result)
      error = result
      raise ActiveRecord::Rollback
    end
  end

  if error
    failure.call(error.value)
  else
    success.arity == 1 ? success.call(result) : success.call
  end
end

#call_each(*fns, failure:, success:) ⇒ Object

‘call_each` composes a list of functions into a single function which it then passes along to a `call` to perform the workflow logic.

Each fn should have the rough type: “‘

fn

void -> ReturnValue

“‘
