And the next update could require the existence of a field (see this navbar function, which wasn't used in earlier versions of the packaged views). web2py's auth is take it or leave it.

[web2py] Re: Default table schema for the Auth tables
web2py's auth is take it or leave it.
I disagree. You can find the definition as Anthony suggests in the source
of gluon/tools.py.
You can add fields with
auth.settings.extra_fields['auth_user']=[Field('address')]
You should not remove fields. because they are the minimum necessary to
make things work. You can remove first_name and last_name but life is
easier if you simply make them invisible.
You do not have to use {{=auth.navbar(...)}} in your layout.html.

Re: [web2py] Re: db._adapter.reconnect()
In your model definition if you use :
unique=True
For each field, It should build your db correctly... But maybe you want
both field together to be unique...
I don't remember how, but I think there is a way to tell web2py about
multiple column constraint. I customize validator for doing this... I can
show a bit the code if you want.

[web2py] session store
Hi I'm doing some tests with apache+mod_wsgi. The idea is to share sessions between two web servers. I've stored sessions in an external server (using DB and memcache), both of them wotk fine but I find that sessions stored in memcached are deleted in five minutes. Capturing web2py-memcache tcp dialog, I see that web2py stores the session key with a deletion time of 300 seconds. Can I change this value from my model/controller ? something like session.timeout? The next configuration I'd like to try is haproxy as http load balancer with sticky sessions (stored locally in each server), the idea is to always have the site available. I've noticed that some changes, for example apache config o web2py routes, require a restart of the http service because a reload doesn't work. Apache will be down for a few seconds untill it restarts, and I think haproxy will follow requests to the other server, losing the session. To avoid a single point of failure I'm thinking about: - 2 haproxy servers - N apache web servers with web2py (N = 2) - external sql/memcache to store sessions, with some kind of redundancy. The data to be accessed are legacy databases and webservices, I can't change anything there. What do you think about this configuration? Any other ideas?

Re: [web2py] Re: How to add an input field in SQLFORM.grid??
Richard,
I tried Massimos approach but it created one form button rather than one
for each row. For my uses, it wont cut it. I need one text field plus a
button on each row. I was able to accomplish this like this
links = [lambda row: INPUT(_name='qty', _value='1'), lambda row: A('+',
callback=URL('cart_callback',vars=dict(id=row.id,action='add',qt=request.
vars.qty)))]
Maybe I did not make myself clear but I just want to have a product grid
with all the products and the qty. Sort of a storefront, so the input text
is not db attached. Click on the button and add it to my cart.. Hmmm but it
seems you want to have like a bulk functionality with the grid, right???

Re: [web2py] Database connections speed issue
To debug do some tests on the web2py machine using psql with -h check for the time it takes to connect to the remote postgresql server and the time to process a query. If the connection takes a long time to setup, it is most likely some dns related problem. If the queries are slow to complete, then you should check the same queries but from the server machine itself, if it is slow in both cases it is a problem with that machine, else if it is slow just on the web2py machine it is a network related problem. If there is no speed issue using psql then try doing some dal queries calling web2py on console with -S and -M options. If that is fast the problem is related to something else in the code. mic Il 13 aprile 2012 20:56, Bruce Wade bruce.w...@gmail.com ha scritto: Linode same datacenter different nodes On Apr 13, 2012 11:53 AM, Bruno Rocha rochacbr...@gmail.com wrote: are you connecting by internal private network or over the internet? there are firewall filtering the packages?

Re: [web2py] Re: db._adapter.reconnect()
This solution look great, because until now web2py was triggering a error if postgres return not unique and won't insert the data... So, maybe as you suggest Johann this is not the case anymore with recent web2py update, I don't know. But I think we would need a confirmation about Massimo or other Core developper about that. Anyway, I will remember the Michele solution and try it, it looks effective. My only concern about that is if you don't write a custom validators that will check the constrain at the form level, the user will never understand their mystake and maybe don't even know their information have not been inserted in database if it failed silently...

[web2py] Re: Default table schema for the Auth tables
I think I will just make those fields invisible for now. Defining custom

must be kept (except for auth_user, which is used as an example in the
manual) for both current and future releases.
Thanks all!

I disagree. You can find the definition as Anthony suggests in the source
of gluon/tools.py.
You can add fields with
auth.settings.extra_fields['auth_user']=[Field('address')]
You should not remove fields. because they are the minimum necessary to
make things work. You can remove first_name and last_name but life is
easier if you simply make them invisible.
You do not have to use {{=auth.navbar(...)}} in your layout.html.
[web2py] Design of a minimal chat-like application in Web2py
Hi group, I am trying to make a minimal multiuser chat-like app using Web2py. Nothing too fancy here, I just need the app to be able to do the following: 1. client browsers can send the receive text msgs from a server 2. server may manipulate the msgs received and selectively routes those msgs to different client browsers 3. server pushes msgs to client browsers using either comet or websocket or (something else? please enlighten me here). 4. it would be nice if the server can remember the client so that if a client drops and comes back in, all the previous sent/received msgs are remembered and shown, but this is not essential. So how should I design this given the MVC model of Web2py? What extra pieces (besides Javascript on the client side) do I need? Thanks!

The problem I had was to read directly Excel file, I would need to write
a lot of code with xlrd. If I can avoid that I will be happy :)
Thanks.

yes and not and what I said needs clarification.
grid = SQLFORM.grid(create=False,update=False) is not a form. If
create=True or update=True then it contains a form when you are creating

updating a record. you must avoind a form within a form and you can do so
in the view:
{{if grid.create_form or grid.update_form:}}
{{=grid}} it is a form
{{else:}}
form{{=grid}} it is not a form but you can embed it in one

Re: [web2py] Database connections speed issue
Ok I fixed the Major slow problem. It was a coding bug, where a session variable was checked and if it was not set the database would be queried to count all adviews currently over 12 million. however the session variable was never updated so this query was always called on every link click :( Thanks for the troubleshoot support.

If there is no speed issue using psql then try doing some dal queries calling web2py on console with -S and -M options.

[web2py] Syntax error - can not find solution
Hi all
I have an application that works fine on my development machine (tested with
versions 1.99.4, 1.99.7, trunk and another version (I forget) in alwaysdata)
In WebFaction I have version 1.99.7 and the application throws a syntax

Re: [web2py] Syntax error - can not find solution
The problem is the Python Version, to pass arguments after one list
unpacking *works you need to run Python 2.7+
to solve your ptoblem an run it on webfaction Python you need to replace
retorno = DIV(*works, _id='submenu2')
with this:
retorno = DIV(*works, **{_id:'submenu2'})

[web2py] Curious appengine memcache exception
I am stumped by a problem I am having with memcache on App Engine. It mostly looks like a memcache issue but I am seeing something funny when I step through the code. I am getting an excpetion (TypeError: 'NoneType' object is not callable) when writing an instance to memcache. The instance comes from a simple class that should be pickleable, containing only strings, booleans, an int, and a datetime. The reason I am bringing this to the web2py board is that when I traced down the memcache call chain to a call to pickler.dump() and attempted to step into it, control jumped to code for web2py's _Web2pyImporter object in gluon/custom_import.py. Here is the relevant section of my pdb session. /Users/davidp/dev/python/google/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/memcache/__init__.py(403)_do_pickle() - pickler.dump(value) (Pdb) s --Call-- /Users/davidp/dev/python/rage/gluon/custom_import.py(253)__call__() - def __call__(self, name, globals=None, locals=None, I stepped through the _Web2pyImporter code, and eventually, when executing the following statement, (line 292-3), control jumped into gluaon/dal.py where it executed the __getattr__() method of the Reference class. return super(_Web2pyImporter, self).__call__(name, globals, locals, fromlist, level) The __getattr__ returns None (it was looking up something called '__getstate__') which causes something to throw an exception. I am, by this time, just scratching my head. Why is appengine's memcache code invoking gluon code? Why is class Reference involved? The object that memcache is pickling contains no DAL references. Why is custom importing needed at all? The 'name' parameter to the Web2pyImporter function __call__ has a value of datetime. There is a datetime field in the object I'm trying to write to memcache, but why does the code jump to custom_import.py when the call to pickler.dump() is called? Here is the memcache code that was being executed at the time: def _do_pickle(self, value): Pickles a provided value. pickle_data = cStringIO.StringIO() pickler = self._pickler_factory(pickle_data, protocol=self._pickle_protocol) if self._persistent_id is not None: pickler.persistent_id = self._persistent_id pickler.dump(value)# line 403 return pickle_data.getvalue() Here is how the pdb showed the control flow as I stepped through _do_pickle(). (Pdb) n /Users/davidp/dev/python/google/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/memcache/__init__.py(403)_do_pickle() - pickler.dump(value) (Pdb) s --Call-- /Users/davidp/dev/python/ragearchives/gluon/custom_import.py(253)__call__() - def __call__(self, name, globals=None, locals=None, The stack trace from the exception is copied below. Why doesn't it show the call into pickler.dump or custom_import? I am most confused. All I want to do is to store my object in memcache and my client is getting impatient. Is this a web2py issue?

How do you view web2py tickets that are generated while running on Google's devserver? When I look at a ticket using the SDK console, it is encoded in a way that I don't recognize. Like this: (dp0 S'output' p1 Stype 'exceptions.TypeError' 'NoneType' object is not callable p2 sS'layer' p3 S'/Users/davidp/dev/python/rage/applications/rage/controllers/default.py' p4 sS'code' p5 S'# -*- coding: utf-8 -*-\n'\n\n@auth.requires_login()\ndef index():\n\tresponse.title = \'Archives\'\n\n\tresponse.files.append What is this format? Is there a viewer for looking at the tickets? I can puzzle out the contents, but it is inconvenient and sometimes time consuming.

[web2py] Re: new feature in trunk: full auditing
I'm have been trying to test this new audit function in trunk, but so far
the mything_archive table has never been created in any of my tests.
Is this the current state of the implementation, or am I missing something?
I downloaded the latest trunk and used it web2py admin to create a new app.
I then modified db.py according to the instructions in this thread:
auth = Auth(db, hmac_key=Auth.get_or_create_key())
auth.define_tables(username=True, signature=True)
...
db.define_table(points,
Field('type','integer'),
Field('point','integer'),
Field('pointname','string'),
auth.signature)
auth.enable_record_versioning(db)
I've tried this with both mysql and sqlite databases, but no *_archive
table...
Any comments or suggestions?
thanks, - Tom

how does it work? every table, including auth_user will have an
auth.signature including created_by, created_on, modified_by, modified_on,
is_active fields. When a record of table mything (or any other table) is
modified, a copy of the previous record is copied into mything_archive
which references the current record. When a record is deleted, it is not
actually deleted but is_active is set to False, all records with
is_active==False are filtered out in searches except in appadmin.
Pros:
- your app will get full record archival for auditing purposes
- could not be simpler. nothing else to do. Try with
SQLFORM.grid(db.mything) for example.
- does not break references and there is no need for uuids
- does not slow down searches because archive is done in separate archive
tables
Cons:
- uses lots of extra memory because every version of a record is stored
(it would be more efficient to store changes only but that would make more
difficult to do auditing).
- slows down db(...).update(...) for multi record because it needs to copy
all records needing update from the original table to the archive table.
This requires selecting all the records.
