Google App Engine

[Tommi]

Looks nifty. The released SDK also includes a mini web app framework
(called `webapp`) that is somewhat similar to web.py -- has e.g. get/
post handlers, although for the most part things are more directed
towards Google's own infrastructure.

One can host web.py apps there, also.

[Aaron Swartz]

I just got back from the introduction at Google HQ. I'm working on
getting a web.py app up now.

[BjornT]

Man I wish I had known about this, I would have been there at Google.
I should pay more attention to my baypiggies mailing list.

[Aaron Swartz]

OK, my first web.py app is up at:

http://webpy.appspot.com/

Click for the source code. (It's 0.3, but I expect 0.2 would work fine
the same way.)

Doesn't seem to be any trouble using web.py at all.

[Curt Micol]

I have to say, I am pretty impressed with what I've read so far. Now
I have to wait for an invite.

Thanks,

how do you start /configure this app with web.py? is a config file needed ?

[rkm...@gmail.com]

OK, I got it configured with app.yaml file

application: helloworld
version: 1
runtime: python
api_version: 1

handlers:
- url: /.*
script: code.py

but when i try to run it says app has no cgirun attribute.. i am using
latest web.py dev 0.3 version. how to fix this?

Oops, I forgot to check in cgirun. Should be fixed now. Sorry.

can you make a release for web.py .23 also?
thanks

[Aaron Swartz]

For 0.23, just do:

import google.appengine.ext.utils
main = google.appengine.ext.utils.run_wsgi_app(web.wsgifunc(web.webpyfunc(urls,
globals()))

[rkm...@gmail.com]

Can you also make available templates/index.html for completeness?
thanks

I am so excited!!
This is something BIG for python developers. Free google accounts for
python development. Am I dreaming??

By the way, "webapp" looks surprisingly similar to webpy.
I can't wait to get some spare time to get my hands on this...

[Aaron Swartz]

> By the way, "webapp" looks surprisingly similar to webpy.

Yeah, I noticed the same thing.

I added the template to the source code for those who are curious:

http://webpy.appspot.com/source

The above didn't work for me, but this did:

import google.appengine.ext.webapp.util
main =
google.appengine.ext.webapp.util.run_wsgi_app(web.wsgifunc(web.webpyfunc(urls,globals())))

Dude, I'm this close to banning the next person who asks about Cheetah
on this list. This is not the Cheetah users support group.

I'm getting an error when trying to start the server:

The app.yaml file is as follows:

Any hint?

You're already in the webpyapp directory; you either need to "cd .."
first or do:

dev_appserver.py .

[Bjorn Tipling]

Would be nice to integrate the datastore with db.py:
http://code.google.com/appengine/docs/datastore/creatinggettinganddeletingdata.html

Has an interesting SQL + put/get syntax.

[Aaron Swartz]

I'm not sure it needs to be integrated; as my example app shows it
works just fine with web.py out of the box. What could we add?

[paul jobs]

import os, sys
sys.stderr.write(db.__file__ + '\n')

What is the use of these lines at the end of the code.py source you have share aaron

That was just debug code; I took it out a while ago.

I am having trouble adding session middleware for google app-engine..
does anyone have examples for doing this for 0.23 or 0.3??

this doesnt work for .23
def session_mw(app):
return FacebookWSGIMiddleware(app, config_fb,
facebook_class=facebookstuff.Facebook)

import google.appengine.ext.webapp.util
main = google.appengine.ext.webapp.util.run_wsgi_app(web.wsgifunc(web.webpyfunc(urls,
globals
(), session_mw)))

and how do i do it for 0.3?
thanks

[krishna2]

I guess, something like this ?

from Cheetah.Template import Template
print Template(file="templates/file.tmpl", searchList=[locals()])

-k

a) installed webpy 0.3 on my system (python setup.py install)
- I added the 0.3 source because the sample Aaron supplied works
without changes

b) To allow remote development add webpy.web (web/) to your source
directory
for uploading.

c) To allow local development you have to let the google code see
webpy.web
so create a symbolic link from your webpy install to a web directory
up from
your source code in the root dir of your google appengine install

ln -s /usr/lib/python2.5/site-packages/web web

This is mentioned in the docs ~
http://code.google.com/appengine/docs/python/purepython.html

d) I've found problems with Cheetah. I had it installed and received
errors
because it calls strop. So I removed my local copy and the error
stopped.

e) You should be able to work locally & remotely using webpy.

You can see a screencap of a demo http://flickr.com/photos/bootload/2421595533/
where I tried:

- import web
- dir(web)

Nothing special, but proved to me webpy installs well. The source app
Aaron supplied ~ http://webpy.appspot.com/ also works out of the box.

As a side note one of the original developers Bret Taylor based app-
engine
and Friendfeed http://bret.appspot.com/entry/experimenting-google-app-engine
on webpy. A good reason to work with webpy.

[davidp]

I'm having the same problem but still didn't got it working... btw,
when installing the Google App Engine SDK it didn't
updated the PATH variable... could you tell me what you've got in it?

One weird thing about the error is that it's not even looking for the
app.yalm file in the right directory, check this out:

mac:googleapps diecinueve$ dev_appserver.py /Users/diecinueve/Sites/
googleapps/helloworld/

Traceback (most recent call last):

File "/usr/local/google_appengine/google/appengine/tools/
dev_appserver.py", line 2425, in LoadAppConfig
raise AppConfigNotFoundError
google.appengine.tools.dev_appserver.AppConfigNotFoundError

any ideas on what to do?

thanks,
david.

Seems since rev 232 of webpy 0.3 : it doesn't work anymore ...
only "page not found"

[manatlan]

in fact, it seems it's a "web.subdomain_application" problem ...
domain mapping seems to do nothing

[manatlan]

it's clearly that !
doctests of application.py don't pass !

see here :
File "application.py", line 428, in __main__.subdomain_application
Failed example:
app2.request("/hello", host="hello.example.com").data
Expected:
'hello'
Got:
'not found'
