change#2: only ask for fields_for when fieldset is not nil
this is not a change, it just saves the fields_for cost
also align with above

hello @bf4 , sorry about pinging directly, could you take a look when you have a moment ? 🙏 |

I'm on vacation and haven't read too carefully If tests pass and it works for people, that's fine with me There are some changes which are refactors which may introduce possible bugs. When that's the case, it's often worth extracting just the refactors and any work which supports the change you want, but doesn't change behavior, so that the actual code change which changes the behavior is smaller and safer and easier to review. That is, make a new pr without the behavior changes, merge it, then rebase/update the feature pr |

ok, let me separate the change from refactoring have a nice vacation :D |

change#1: only initialize ActiveModel::Serializer::Fieldset when fieldset is not nil
instance_options[:fieldset] could be:
- the
fieldsetpassed in through option ActiveModel::Serializer::Fieldsetinstance- nil

That's fine. Or add a class method on fieldset which does what's in this begin block

echoing what you previously mentioned, I also want keep the changes minimal 🙏
if it's necessary, is it better to do it in another refactoring PR?
