It's not an "awesome" one but my requirements were to not have images and to not have any javascript. I want it to be fast and functional. I currently have the load event and domcontentloaded event in chomium fired in less than 400ms. You can see it here: http://feeds.uni.me from memory my setup is: - nginx with uwsgi protocol, but not with uWSGI server. I implemented a subset of uwsgi protocol in pure python to be able to use eventlet (I think uWSGI server doesn't support eventlet). - sessions and cache are stored in redis. - sqlite database. Currently it has near 30 (~665Mb) articles in it. One thing I learn is that sqlite is very slow to "select count(*) from table", I was using this query for pagination with pages, than I change to only newer, older buttons to avoid the count(*). - search is powered by whoosh and bottle - Web2py is querying through a simple restful api. I have 2 separated whoosh indexes, one for portuguese articles and the other for english. - a background job to collect and process the feeds, than the feeds are stored in sqlite and added to whoosh index. - perp (http://b0llix.net/perp/ - similar to daemontools) to control all the pieces - a small VPS with 256Mb of RAM.

[web2py] Using whoosh with web2py
I'm using whoosh backend with plugin_haystack in my application. But the search function is working only if there is an insert or update db statement in that function. For instance : def temp(): db.my_table.insert(my_row1="temporary data to test the search") rows = db(index.search(my_row1="data to search")) return dict(rows=rows) this returns the newly inserted row as the search result. But after that if I do this, it doesn't return any matching result, def temp2(): rows = db(index.search(my_row1="data to search")) return dict(rows=rows) what could be the mistake here? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: MySQL - OperationalError: Error on rename (errno: 150)
I realize this is an ancient topic, but I'm having the very same error
migrating a MySQL table where I'm only removing a self reference field.
It seems like an index was created to guard the (self) foreign-key
constraint and DAL doesn't remove it when deleting the field.
There are no manually-created indexes on my database, all were created
automatically.
Just wondering if this was fixed.

[web2py] Re: APNSFeedbackWrapper receive method freezes
I have used PyAPNS https://github.com/simonwhitaker/PyAPNs for this with
some degree of success in the past.
What I do is to send the notifications 1 by 1 which is quite slow but at
least you can catch invalid tokens. This is the relevant part of the code I
use:
for device in ios_devices:
try:
apns.gateway_server.send_notification(device, payload)
except socket.error as e:
# Most likely cause of a broken pipe is this token being
invalid! (maybe the user uninstalled)
apns = APNs(use_sandbox=False, cert_file=cert, key_file=key)
logger.debug('SOCKET ERROR - ' + str(e.errno) + ' deleting ' +
device)
db((db.push_devices.platform == 'ios') &
(db.push_devices.device_id_or_token == device)).delete()
continue

[web2py] Re: how to disable "register" item from the default upper right-hand side dropdown
I believe you should still be able to create a registration form explicitly via auth.register() (though please try it to confirm). However, if you use something like the default user action: def user(): return dict(form=auth()) and call it with a URL like /myapp/default/user/register, it will not generate a register form (because the register action was disabled).

[web2py] Re: APNSFeedbackWrapper receive method freezes
Hi Leonel,
Thank you for your answer.
While I was waiting for an answer to my problem I implemented a solution
very similar to yours. But I have that code (similar to yours) inside a
thread to avoid its slow performance.
The problem is, as I tell here, in other post
(https://groups.google.com/forum/#!topic/web2py/LIO5xU3pjyM), that I don't
know how to use DAL inside a thread because I always get crashes or errors
due to closed connections in main thread.
So, I will need to know how to use DAL inside a thread or to know how to
use feedback class of APNSWrapper.
Thanks again and kind regards!

You can use the included web2py scheduler instead of using your own threads to do what you want. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

I'll study this. But, could I use DAL inside the scheduler and work with my database without errors as I have working with threads? Thank you!
