So i’ve just finished the google app engine greetings tutorial. All well so far. I then decided to try and add a new datastore model and then set it in the existing handler. I added a 2nd content field called “content2” and then tried to set it in the handler Guestbook(), but it keeps borking out. I’m sure it will be the silliest error, but I’m stumped atm. Any ideas?
main.py
import cgi
from google.appengine.api import users
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from google.appengine.ext import db
import os
from google.appengine.ext.webapp import template
class Greeting(db.Model):
author = db.UserProperty()
content = db.StringProperty(multiline=True)
date = db.DateTimeProperty(auto_now_add=True)
content2 = db.StringProperty(multiline=True)
class MainPage(webapp.RequestHandler):
def get(self):
greetings_query = Greeting.all().order('-date')
greetings = greetings_query.fetch(1000)
if users.get_current_user():
url = users.create_logout_url(self.request.uri)
url_linktext = 'Logout'
else:
url = users.create_login_url(self.request.uri)
url_linktext = 'Login'
template_values = {
'greetings': greetings,
'url': url,
'url_linktext': url_linktext,
}
path = os.path.join(os.path.dirname(__file__), 'index.html')
self.response.out.write(template.render(path, template_values))
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.content2 = self.request.get('content')
greeting.put()
self.redirect('/')
class HelloWorld(webapp.RequestHandler):
def get(self):
self.response.out.write('Hello, webapp World!')
application = webapp.WSGIApplication(
[('/', MainPage),
('/sign', Guestbook)],
debug=True)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
index.html
<html>
<body>
{% for greeting in greetings %}
{% if greeting.author %}
<b>{{ greeting.author.nickname }}</b> wrote: Dogs name is: {{ pet.name }}
{% else %}
An anonymous person wrote:
{% endif %}
<blockquote>{{ greeting.content|escape }}</blockquote>
{% endfor %}
<form action="/sign" method="post">
<div><textarea name="content" rows="3" cols="60"></textarea></div>
<div><input type="submit" value="Sign Guestbook"></div>
</form>
<a href="{{ url }}">{{ url_linktext }}</a>
</body>
</html>
I can’t see anything wrong with your code. Off the top of my head I would say check the white spacing in front of your new item.
Other than that what is the error message shown? The error message that appears in the log is a lot more user-friendly than the browser error message.
