lazy load for association

[zgid123]

Hi,

I wanna skip association if I don't eager load it. The association extractor does not support it at the moment I guess.

I wonder what is the correct way to do the lazy load for blue printer?

Thanks.

The feature request I read here is optional associations. Blueprinter already has optional fields via if: and unless:, and it seems reasonable that associations should have the same.

Rails already has a way to detect if associations are eager loaded. So if Blueprinter adds if/unless options for associations, it could be done like this:

class WidgetBlueprinter < Blueprinter::Base
  association :category, if: ->(_field, widget, _opts) {
    widget.association(:category).loaded?
  }
end

Thanks for your answer. But I think I will monkey patch the extractor because if we use that approach, every association needs the condition

@zgid123 this is outside of the scope of Blueprinter and has been discussed already in #294. Although blueprinter might open up avenues to assist it, it would not support it natively. Pls follow discussions around #341 / #357 for future scopes.
