rest - Convert a string to another Python class -

is there anyway create class model?

for example, have model.py, 1 of class inside contains:

class customers(ndb.model):   lastname = ndb.stringproperty()   firstname = ndb.stringproperty()   license = ndb.stringproperty()   birthdate = ndb.dateproperty()   remarks = ndb.textproperty() 

i know can models using dir(model), , outputs like:

['customers', 'customeraddresses','whatever','__builtins__', '__doc__', '__file__', '__name__', '__package__', 'ndb'] 

however, there way can use these string inside dir(model) automatically generate class, like:

class restcustomers(webapp2.requesthandler):   #some code gets model class attributes , displays json string    customers = # customer attributes model   self.response.headers['content-type'] = "application/json"   self.response.write(json.dumps(customers)) 

i'm not sure if possible, kind of way javascript works, wherein like

var models = dir(models); // array var class = "rest"+models[0]; 

or that...

try this:

from google.appengine.ext.ndb import metadata class restcustomers(webapp2.requesthandler):     customers = metadata.get_properties_of_kind(customers)     self.response.headers['content-type'] = "application/json"     self.response.write(json.dumps(customers)) 

for more information, see documentation metadata. not sure how get_properties_of_kind expects kind argument try out.
