class - Python: Loop over NDB entity model -

i have class/ndb entity model defined follows:

class cashmodel(ndb.model):     "models cash record"     # name, balance, interest rate     accountname = ndb.stringproperty()     interestrate = ndb.floatproperty()     balance = ndb.floatproperty()     accounttype = ndb.stringproperty()     futureview = ndb.jsonproperty()     time_stored = ndb.datetimeproperty(auto_now_add=true) 

once values added class, print out of looks this:

cashmodel(accountname=u'bank', accounttype=u'cash', balance=1000.0, futureview=none, interestrate=5.0, time_stored=datetime.datetime(2015, 7, 7, 18, 33, 3, 925601)) 

how loop on key/value pairs of class, output like:

accountname, bank accounttype, cash balance, 1000.0 futureview, none interestrate, 5.0 time_stored, datetime.datetime(2015, 7, 7, 18, 33, 3, 925601) 

looked through other answer on s.o., none seemed fit. simple solution using built-in method best. tia

you can use to_dict(include=none, exclude=none) instance method convert model object dictionary , use iteritems() iterate on key/value pairs

to_dict(include=none, exclude=none) 

returns dict containing model's property values.
