[google-appengine] Re: Forming url with id number
I figured that
i_id = item.key().id()
logging.info("i_id is: %s" % item.key().id())
gets the id number. Can anyone help about forming the corresponding
url?
Thanks.

[google-appengine] Re: Forming url with id number
converting the id to string appears to have solved the problem:
self.response.out.write("")
for item in items:
self.response.out.write("""%s
comments """ %
(cgi.escape(item.url),
cgi.escape(item.title), cgi.escape(str(item.key().id()
self.response.out.write("")

Thanks for this information! Exactly what I was trying to understand.
I changed the handler like this:
class Article(webapp.RequestHandler):
def get(self, id):
id = int(id)
self.response.out.write("""article title """ %
(id))
and it works fine. But now how do I get the article title from the
other handler where it is inside the for loop. Because in this handler
I cannot use "item.title". What is the way to do this?
Thanks again.

Thanks for your help. This works:
class Article(webapp.RequestHandler):
def get(self, id):
id = int(id)
item = Item.get_by_id(id)
...
self.response.out.write("""%s """ %
(cgi.escape(item.url),
cgi.escape(item.title)))

[google-appengine] Re: Forming url with id number
Thanks. Disqus works great but I am having a styling issue that may be my fault. I use and the count shows as "x comments". In other words, disqus does not recognize my link text; even if it ıs blank it shows "x comments" like in this page http://sarah-for-president.appspot.com/ On Jan 16, 10:04 pm, "Nick Johnson (Google)" wrote: > Hi Zeynel, > > You might want to read my blog post about using Disqus on App > Engine:http://blog.notdot.net/2009/10/Blogging-on-App-Engine-part-6-Comments... > > You don't need to do anything special - just create one page for each item > that people can comment on, and embed the Disqus code in that page. > > -Nick Johnson > > > > > > > > > > On Sat, Jan 15, 2011 at 11:38 AM, Zeynel wrote: > > Hello, > > > I am working on a simple news site for people to post Sarah Palin > > related links.

Re: [google-appengine] Re: Forming url with id number
You could use the URL dispatcher to check for validity of the passed
id by making the id part of the URL
http://me-for-president.appspot.com/item/1
in the code
class ItemPage(webapp.RequestHandler):
def get(self, id):
id = int(id)
# rest of the handler
application = webapp.WSGIApplication([('/item/(\d+)', ItemPage)],
debug=True)
def main():
run_wsgi_app(application)
Use some sort of template engine. Much easier if the site or pages gets bigger.

Re: [google-appengine] Re: Forming url with id number
First you make an index page containing all the items you want to show
based on a filtering, maybe date.
class ItemIndexPage(webapp.RequestHandler):
def get(self):
items = Item.all().filter(...some filter...).fetch(1000)
self.response.out.write("")
for item in items:
self.response.out.write("""%s
comments """ %
(cgi.escape(item.url),
cgi.escape(item.title), cgi.escape(item.key().id(
self.response.out.write("")
And deal with the individual item in the next handler
class ItemPage(webapp.RequestHandler):
def get(self, id):
id = int(id)
item = Item.get_by_id(id)
# rest of the handler
application = webapp.WSGIApplication([('/items',
ItemIndexPage)],('/item/(\d+)', ItemPage)],
debug=True)
