[google-appengine] Re: INPUT-OUTPUT applications using DATASTORE
Hello everybody from Greece
I want to do this simple task:
To create an application that will create a datastore and get user input. It is
like the 1st part of the Guestbook application. Then I want to create another
application like the 2nd part of the Guestbook application to print the user
input the 1st part has collected.
For the 1st part I have created my datastore with greetings as input. It worked
(1st+2nd part together)
For the 2nd part I use the code:
#Retrieve using Gql from table the query
class Greeting(db.Model):
author = db.UserProperty()
content = db.StringProperty(multiline=True)
date = db.DateTimeProperty(auto_now_add=True)
class MainPage(webapp.RequestHandler):
def get(self):
greetings = db.GqlQuery(SELECT * FROM greeting ORDER BY date DESC LIMIT 10)
results=greetings.fetch(10)
#testing output
self.response.headers['Content-Type'] = 'text/plain'
self.response.out.write('Testing..')
self.response.out.write('htmlbody')
for result in results
self.response.out.write('content'+result.content)
class Guestbook(webapp.RequestHandler):
def post(self):
greeting = Greeting()
if users.get_current_user():
greeting.author = users.get_current_user()
greeting.content = self.request.get('content')
greeting.put()
self.redirect('/')
application = webapp.WSGIApplication([
('/', MainPage),
('/sign', Guestbook)
], debug=True)
def main():
run_wsgi_app(application)
if __name__ == __main__:
main()
The above code is not working. Have any ideas, I would appreciate.
Best Regards,
COSTAS Anastasiades

Hi Costas,
What kind of errors are you seeing? It's difficult to read the code
highlighted, so if you could include a stack trace or other information,
that would be helpful.
Thanks,
Marzia
