PATCH update instead of full PUT request

[aliismayilov]

Here's an idea how activeresource could be better. At the moment, when you do

account = Account.find(1)
account.name = 'new name'
account.save

the last line fires a full PUT request which includes unchanged attributes of the account object.

As I see, activeresource gem already includes activemodel gem as dependency. We could maybe use of the ActiveModel::Dirty#changed functionality and send a PATCH request with only the fields which have changed.

the same could apply for account.update_attributes({name: 'new name'}) as well.
