python - How to render JSON on client-side from Google App Engine Entity -

i appreciate on rendering json object on client-side google app engine entity.

here of relevant code:

def render_str(template, **params):    t = jinja_env.get_template(template)    return t.render(params)  class bloghandler(webapp2.requesthandler):    def write(self, *a, **kw):       self.response.out.write(*a, **kw)     def render_str(self, template, **params):       params['user'] = self.user       return render_str(template, **params)     def render(self, template, **kw):       self.write(self.render_str(template, **kw))  class post(ndb.model):    subject = ndb.textproperty(required = true)    created = ndb.datetimeproperty(auto_now_add = true)    startdate = ndb.datetimeproperty()    enddate = ndb.datetimeproperty()  class postpage(bloghandler):     def get(self, post_id):     key = ndb.key('post', int(post_id), parent=blog_key())     post = key.get()     postdict = post.to_dict()     postdict['startdate'] = postdict['startdate'].isoformat()     self.render("permalink.html", postdict = postdict) 

in script tag on template page, include

<script> var jsonobject = json.parse({{ postdict['startdate']}}); var jsonobject1 = new date(jsonobject); </script>     

am on right track here? use datetime object on client-side jquery functions.

any in pointing me in right direction appreciated.

there number of problems code. first of all, once convert post dictionary postdict, can't reference elements dot notation. have use dictionary reference postdict['startdate'] reference startdate element.

next, use isoformat() function when storing date in json format:

postdict['startdate'] = postdict['startdate'].isoformat() 

this makes easier convert javascript date object:

<script> var jsonobject = json.parse({{ postdict.jsonobject}}); jsonobject[0].y = new date(jsonobject[0].y); </script>
