I am new with GAE. Started with installing python 2.7.1 and
GoogleAppEngine-1.4.2 on Windows 7.
And I am using SQLite 3. Then I followed instructions on Web.py site to
install web module. python setup.py install
When I import web module on python console it works as expected
$python
Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import web
>>>
I created a sample application using web.py framework. Here is my code.py
==============================================================
import os
import web
from web import form
os.path.join(os.path.dirname(__file__), 'templates/')
render = web.template.render('templates/')
db = web.database(dbn='sqlite', db='testdb')
urls = (
'/', 'index',
'/todo(/?|/edit/?|/delete/?)(\d*)', 'todo'
)
app = web.application(urls, globals())
class index:
def GET(self):
return render.index()
class todo:
def GET(self,mode,args):
if args:
items = db.select('todo',where='id={0}'.format(args))
item = items[0]
todoform = form.Form(
form.Textbox("id", value=item.id),
form.Textarea("title", form.notnull, value=item.title),
form.Textbox("created", value=item.created),
form.Checkbox('done', checked=(item.done!='f')))
return render.todo_item(todoform(),mode)
todos = db.select('todo')
return render.todo(todos)
def POST(self,mode,args):
i = web.input()
if args:
if mode == "/delete/":
n = db.delete('todo', where='id={0}'.format(args))
raise web.seeother('/todo')
if mode == "/edit/":
taskdone = "t" if (i.has_key('done')) else "f"
n = db.update('todo', where='id={0}'.format(args), title=i.title,
done=taskdone )
raise web.seeother('/todo')
else:
n = db.insert('todo', title=i.title)
raise web.seeother('/todo')
if __name__ == "__main__": app.run()
==============================================================
And this code works as expected when I start server from command line
==============================================================

Then to deploy I added app.yaml and index.yaml files in same folder as
code.py
When I run dev_appserver.py I get * import web **ImportError: No module
named web*
