I'm struggling to display my array items in the template. Just started with Entity relationships in GAE and I'm not finding suitable solutions on SO. Do i have to perform a query first in my handler. if so, how coz I'm struggling with the logic.
Datastore
Project
Employees
class Project(ndb.Model):
projectID = ndb.IntegerProperty(required=True)
title = ndb.StringProperty(required=True)
description = ndb.StringProperty(required=True)
startAt = ndb.DateTimeProperty(indexed=True)
endAt = ndb.DateTimeProperty()
isFullDay = ndb.BooleanProperty()
days = ndb.KeyProperty(kind='CompanyDay', repeated=True)
employees = ndb.KeyProperty(kind='Employees', repeated=True)
client = ndb.KeyProperty(kind='Client')
class Employees(ndb.Model):
name = ndb.StringProperty()
role = ndb.StringProperty()
data

<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="">

<div class="project-info">

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())) for proj in projects], default=date_handler))
var vm = this;
vm.projects = [];
$http.get('/comments')
.then(function(result) {
console.log(result);
vm.projects = result.data;
});
You could change your date_handler to handle ndb.Key to properly render your Employee collection in your 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 to change the name of this method as it is not just doing date_handling any more
