not sure where you got the :condition from but try this

def accepted_accounttransactions    accounttransactions.inject(0) {|total, at| total + (at.status == 'accepted' ? at.amount : 0 } end

try

def accepted_accounttransactions(filter)   accounttransactions.inject(0) {|total, at| total + (at.status == filter ? at.amount : 0 } end

model.accepted_accounttransactions('accepted')
