Allow field option preload: true and use the field's name as relation name

[Yoshiji]

I was playing with this gem and found out that:

# user object type
field :posts, !types[!PostType] do
 preload :posts
end
# is the same as
field :posts, !types[!PostType], preload: :posts

It would be cool to be able to do a simple preload: true as an option, and it would resolve to the field's name:

field :posts, !types[!PostType], preload: true 
# would resolve to
field :posts, !types[!PostType], preload: :posts

So you would need to give an explicit argument if the relation name does not match the field's name or if you want more than a single relation preload.

What do you think? I could try to add this feature if I am not the only one finding it relevant.

This sounds nice @Yoshiji :) I would prefer your simplified syntax over having to open a new block to defined a single preload

This looks really nice! Is this considered?

I forgot to work on this... I still consider doing it, but I won't be able to do so until few weeks... Don't hesitate to take over this project if you want it ready sooner.
