I have got a feeling that I'm missing something very basic here, please pardon me.
I have a very basic CTF model with some string attributes, some of which are not required, i.e. empty.
With return_nil_for_empty I can have their values be coerced to nil, but as it seems there's no way of setting them? I get NoMethodErrors for every attr_writer to a non-required field that is blank, hence not returned by the contentful API.
