template

data fetched backend through angular's http service

 <md-content  class="md-padding projects" layout="row" layout-wrap>         <md-card ng-repeat="data in controller.projects" flex="20" ng-click="editproject(data)">             <img src="" alt="">             <md-card-content>                 <div class="project-info">                     <h2 class="md-title">{{ data.title }}</h2>                     <p>{{ data.description }}</p>                     <p>{{ data.employees }}</p>                  </div>             </md-card-content>         </md-card>     </md-content>

python code responds /comments

class commentsjsonhandler(webapp2.requesthandler): @classmethod def route(cls):     """     name: index, template: /     """     return webapp2.route('/comments', handler=cls, name='_commments_')  def get(self):       projects = project.query()      def date_handler(obj):         print obj         if isinstance(obj, datetime):             return obj.isoformat()         else:             return str(obj)      self.response.out.write(json.dumps([dict(proj.to_dict(), **dict(id=proj.key.id())) proj in projects], default=date_handler))

from angular - code requests server

    var vm = this;     vm.projects = [];     $http.get('/comments')         .then(function(result) {             console.log(result);             vm.projects = result.data;          });

displaying employees datastore.

you change date_handler handle ndb.key render employee collection in returned json

def date_handler(obj):     print obj     if isinstance(obj, datetime):         return obj.isoformat()     elif isinstance(obj, ndb.key):       return obj.get().to_dict()     else:         return str(obj)

you may want change name of method not doing date_handling more
