[web2py] downloading old web2py version from github

[Richard]

Hello,

I was wanting to get an old version of web2py for some tests purposes and 
discover that even the old version of web2py downloaded from github lead to 
the issue related to new modulized dal (aka pydal)... Is this normal, I 
mean that the old version get affected ?

How some one supposed to have access to an earlier fully working web2py 
version?

Notice also that actually we can start web2py shell like so : python 
web2py.py -S welcome -M

It fails with this message :

Traceback (most recent call last):

[web2py] Re: Show tables

[黄祥]

for show two tables in 1 page i think you can use components, and please 
ensure that use set the different formname for each of your grids
ref:
http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM-grid-signature
http://web2py.com/books/default/chapter/29/12/components-and-plugins#LOAD

for user permissions, i think you can set it on the grid something like
create = auth.has_membership(group_id = 'Admin')
or
create = auth.has_permission('create', db.table1, 0, auth.user.id)

ref:
http://web2py.com/books/default/chapter/29/09/access-control#Authorization

[web2py] Re: After changing db adapter "relation 'auth_user' already exists"

[Niphlod]

the whole uri is inspected to determine the prefix of .table files, so when 
you change the adapter, a migration is triggered.
that being said, it's pretty easy to regenerate .table files ... 
- set fake_migrate_all=True
- hit appadmin one time
- remove fake_migrate_all=True
voilà.
Optionally you can delete old .table files (the ones pertaining the "old" 
uri)

[web2py] Re: cache.redis server unavailable = traceback. Bug?

[Niphlod]

I was thinking about a major overhaul of the connection algorithm. Redis is 
improving quickly and more and more connection options are made available 
at each release. Both redis_cache and redis_sessions should be able to work 
on a "redis-like" connection object. In that rewrite I'd add this "flag" 
too. File a bug anyway on github so it gets tracked

Re: [web2py] deploment on an obsolete Debian 5 server

[Niphlod]

we don't support python 2.5 from some time.. it's possible that "I 
can't import" is a result of "tried and failed" rather than "didn't find 
it".

Pretty cool. Wondering if we can have a web2py version implementing the

 Hi Ramos,

 You should add a web2py application folder to a Sublime Text 
 prokeject
 1. Open Sublime go to the Project menu
 2. Choose Add folder to project option
 3. Browse your web2py application you like to work on

 You are ready to use the W2P plugin

 I am going to make the video tutorial on the weekend and also going 
 to update the plugin read with these steps

 Thank you letting me know

Re: [web2py] Keeping track of connected users (websocket_messaging.py)

[Richard Vézina]

Last year we develop over websocket contrib a tool like that and it turns
that we had to create a thread that was doing that, I mean maintain a list
of connected user... We create a basic back and forth websocket message
format so we can ping every users connected and wait for a response from
them if they are still online... This give you the basic idea how to
implement something... At start I expect that there were a build solution
for this in websocket contrib and toranado, but the person that I mandate
for analysing that and found a solution said that wasn't available and
implement something... So, I don't know if the path he follow was the right
one. But as far as I have been able to go throught that topic, websocket
contrib is noting more then a basic connecting tool that allow you to start
multiplexing using tornado from web2py...

If you feel you are able to review the code of what we did and improve it,
I can share it here, so I know if we take the right path or not... Since
the person who develop that is gone, I can't help more than sharing with
you her works...

[web2py] deploment on an obsolete Debian 5 server

[Alan Etkin]

I was testing the last stable source code installation of the framework on 
a debian lenny don't know what else 5.0 server, but if you start it using 
the built-in web server on a terminal it throws a funny error message 
stating it can't find pydal

Has anyone tried to deploy web2py on that kind of server?
Should I use a compiled newer version of python?

The default O.S. interpreter is 2.5

Thanks

Could it be a browser support issue?

Check out the link for more info and browser support of different font

load all the formats from a CDN (like Google).

 Hi Ramos,

 You should add a web2py application folder to a Sublime Text 
 prokeject
 1. Open Sublime go to the Project menu
 2. Choose Add folder to project option
 3. Browse your web2py application you like to work on

 You are ready to use the W2P plugin

 I am going to make the video tutorial on the weekend and also going 
 to update the plugin read with these steps

React.js is not that new.

They are pretty similar.

Here is an article from May 6th 2014. Exactly 365 days ago.

http://blog.ractivejs.org/posts/whats-the-difference-between-react-and-ractive/

Massimo is already implementing ractive.js into web2py with impressive 
accomplishes.

Let say the FK field is field2 :

Field('field2','reference main_table',  # Better syntax thand
"db.main_table"
 widget=AutocompleteWidgetSelectOrAddOption(
request=request,
field=db.main_table.field1,
 # which is you reprensting field
id_field=db.main_table.id,
limitby=(0, 10),  # how
much records you want in the dropbox
min_length=6,  # when you
want the autocomplete pop in or how many caracters user have to entered
before the autocomplete kickin
form_title=T('Add new

controller="controler name
that contains the below function",

Re: [web2py] Two SQLFORMs side by side?

[LoveWeb2py]

Thank you, Richard. I think i'm getting closer. Could you show me an 
example of how you apply this to a specific field in SQLFORM?

Going back to my original model:

db.define_table('main_table',
Field('field1','string'),
Field('field2','string'),
migrate=False)

db.define_table('second_table',
Field('field1','db.main_table'),
Field('field2','db.main_table')
migrate=False)

How could I integrate your widget with field 2 for a SQLFORM?

IMHO ReactJS is no newer than Ractive.js.  It's being backed by facebook
since a while ago.  I like the author's philosophy (read independence ) and
design simplicity of Ractive.js, things that I appreciate even more in
web2py, but that's a matter of personal taste :-)

 Ractive.js as Massimo imaged is Ractive.js is to Angular.js what web2py
 is to Django

 The main issue with Ractive.js is it documentation which is not to bad
 actually but difficult to apprend, but it lacks of concreate examples...

 The user base seem limited and the project don't seem to be really

 I would have a welcome based on W3 repo that Massimo publish on github

 How to structure correctly the code remain to me a challenge

Re: [web2py] Re: Is it possible to create a webservice funcion for login (instead of basic authentication)?

[Michele Comitini]

if you do not want to use basic auth, a common pattern is  having a service
that generates a temporary token and then having the client pass the token
with each call.

@service.xmlrpc
def get_auth_token(user, password):
   ...
   return token

@service.xmlrpc
def aservicemethod(token, ...):
check_token(...)

you can create a decorator to call check_token in a more elegant and
readable fashion ;-)

Re: [web2py] IS_IN_DB() multiple tables

[Richard Vézina]

A set which you have, but your validator has wrong syntax :

IS_IN_DB(db(db.ipaddress.status=='Free'),db.ipaddress.ip, '%(ip)s')

free_ip_set = db(db.ipaddress.status=='Free')
IS_IN_DB(free_ip_set, 'ipaddress.ip', '%(ip)s')

Try this... You define the set before you server table and after the
ipaddress table..

Re: [web2py] Re: Brainstorming

[Richard Vézina]

I think it will be difficult to make everyone happy with a given choice...

Michele "agnostic" point is good even if in pratice it may be difficult
(let say BS2 for instance we were maried with it until recently)

Ractive.js as Massimo imaged is Ractive.js is to Angular.js what web2py is
to Django

The main issue with Ractive.js is it documentation which is not to bad
actually but difficult to apprend, but it lacks of concreate examples...

The user base seem limited and the project don't seem to be really active...

I would have a welcome based on W3 repo that Massimo publish on github
showing how to properly integrate with Ractive.js

How to structure correctly the code remain to me a challenge

[web2py] After changing db adapter "relation 'auth_user' already exists"

[Ian W. Scott]

To work around my earlier unicode problem (I submitted an issue on Github) 
I switched from the pg8000 adapter to the psycopg2 adapter for my postgre 
database. Everything works fine as long as I have migrate set to False. But 
if I set migrate=True I get this error:

(relation "auth_user" already exists 
)

This is strange because the dal shouldn't be trying to perform any 
migrations. Nothing in the model definitions or the db structure was 
changed. The only change was the db adapter. Thinking my .table files might 
have been corrupted, I tried doing a fake migrate by setting migrate=False 
and fake_migrate_all=True, then switching both values again. But nothing 
has changed. I'm still getting the same error as long as migrations are 
turned on.

Here's the full traceback:

[web2py] Re: cache.redis server unavailable = traceback. Bug?

[Jose C]

Hmm, I see your point and use case.  But... ;)   given that there are 
references in the manual (and probably in reality the majority of use 
cases) to caching views, or db queries, etc.  how about then, as an 
enhancement, to add an init flag to cache.redis along the lines of 
`die_if_server_unavailable = True`  to force a halt with the traceback.  Or 
else if set to False, fail silently and gracefully (key didn't exist 
behaviour, re-execute function)  and let the system keep running?  
Obviously the flag name itself is up for debate.

Would this not provide the best of both worlds and max flexibility?  If you 
(as the cache.redis creator) agree I'll take a stab at adding that 
functionality to redis_cache.py and issue a PR.

[web2py] Re: cache.redis server unavailable = traceback. Bug?

[Niphlod]

up until now, cache behaviours in web2py are a taddle bit different than 
the rest of the world. cache(s) in web2py usually mean "I'd like to compute 
something huge one time only" and so the general idea is that if you need 
to compute it, you should be damn sure to do so. You may also be relying on 
that assumption e.g. to get a huge stream of results from an external 
server that bills you if you go over the quota. 
The "original retry logic" is done to avoid erroring out when redis is 
restarted .  we may add some parameter around to change the behaviour but 
since it's missing from cache.ram and cache.disk for obvious reasons I 
don't know how much traction it could get.

Re: [web2py] Two SQLFORMs side by side?

[Richard Vézina]

The id field and what field you want to show as a representation of the id
field of the referenced table...

Start by putting the widget class in model file even if it not a good thing
to see if you can make it works...

In the module I have these imports :

from gluon.html import *
from gluon.sqlhtml import *
from gluon import current
from gluon.compileapp import LOAD


Which may not be related to the widget class...

[web2py] Re: Caching Logic in web2py

[Massimo Di Pierro]

Mind there is a difference in behavior in cache.ram and cache.disk and 
cache.memcache. Leonel is talking about cache.ram and cache.ram only works 
if you have one single server and only as long the process in the server is 
running. Your web server can arbitrarily restart at will and this will 
invalidate the cache at random time. All changes would be lost.

Cache.disk and cache.memcache instead have a more persistent storage but 
the object you see is only a copy of the one stored.

It is therefore a very bad idea to ever change a change a cached object. 
Something will always break. It is ok to replace such object.

[web2py] Re: Problem using routes_in to convert path elements to vars

[Rich Hogg]

Hi,

I thought I would post a follow-up/update since I haven't seen any comments 
on this. The essence is:

- I believe I have identified a bug in that, while you can use a 
pattern-based incoming route in routes.py/routes_in to strip off part of 
the incoming path and present it as a variable (I verified that it works by 
debugging gluon/rewrite.py/regex_url_in()), the variable is not passed to 
the controller.

- The reason seems to be that gluon/rewrite.py/regex_filter_in() updates 
request.env with the lower-cased keys from environ (i.e. my var ends up in 
request.env['query_string']), but gluon/globals.py/Request.parse_get_vars() 
only looks for vars in request.env['QUERY_STRING']

- I dug this far with the idea that I might be able to contribute a patch, 
but it is not obvious to me how to fix it, since (to start with) I do not 
understand why we have both upper- and lower-case versions of these keys; 
so, I am asking for some discussion.

- In the meantime, I worked around it by parsing request.env['query_string'] 
in the controller (which is working fine).

Thanks,

Rich Hogg

[web2py] IS_IN_DB() multiple tables

[kecajkecaj123]

Hi All, 

I have very basic dtabasae where in one table i have IPs which are used in 
second table:

db.define_table('ipaddress',
   Field('ip', unique=True, length=200,requires=IS_NOT_EMPTY()),
   Field('subnet', length=200, requires=IS_NOT_EMPTY() ),
   Field('status', length=200, default="Free", 
requires=IS_IN_SET(['Free','Used'])),
   format = '%(ip)s')

db.define_table('server',
   Field('servername', length=200),
   Field('port', length=200, requires=IS_NOT_EMPTY()),
   Field('ipaddress', unique=True, length=200, 
requires=IS_IN_DB(db(db.ipaddress.status=='Free'),db.ipaddress.ip, 
'%(ip)s')),
  

The problem i'm having is that with grid i can delete and add new values to 
"server" table and i added function which update status of IP for USED or 
FREE after insert/delete. 
Problem is with Update function as when i try to update server name i need 
to chose IP again and i can't chose same IP as it is marked in ipaddress 
table as USED hence it's not displayed in dropdown menu.
How can i display all IPs that are marked as FREE in ipaddress table AND 
IPs that where currently assign to the record i'm updateing in table 
server? 

Regards.

[web2py] Issues with PythonAnywhere - /proc/meminfo

[Lovecannon]

Hello I'm having some issues with web2py and PythonAnywhere. It seems as 
though the RAM cache function is giving me issues saying that /proc/meminfo 
cannot be opened. Anyone know of any fixes or workarounds related to this? 
It triggers randomly and cleaning the application through the admin 
interface often temporarily fixes the issue.

Re: [web2py] Re: scheduler_run table remains empty

[Christophe Meessen]

Thank you very much.

My question was not clearly formulated. The task I run for my tests is 
very quick (appending a time stamp to a file) so I couldn't see the 
record in the scheduler_run table during this short period because the 
record is deleted when the task terminates.


I was looking for a solution to avoid the deletion of the record in the 
scheduler_run table. I knew it was possible because in my initial 
experimenting with scheduling this is what happened.


After further research I finally found out that to preserve the record 
in the scheduler_run table, _the task must return a result_. It is then 
possible to view the result, the output of the task, at what time it was 
executed, etc.


Le 04/05/2015 20:59, Niphlod a écrit :
is your task returning something ? if it's not returning anything, by 
default the corresponding scheduler_run record is deleted.


On Monday, May 4, 2015 at 5:56:36 PM UTC+2, Christophe Meessen wrote:

I'm using queue_task to execute a task once at a predefined time.
The task itself calls queue_task when it finished executing itself
to submit it self for a later execution at a predefined time. I'm
currently testing it so I call web2p directly with the shell to
check output.

This all works as expected and an entry is created in the
scheduler_task table. When the task completes its status becomes
COMPLETE and a new task is queued and executed at the predefined
time (approximately).

My problem is that the table scheduler_run remains empty. So I
can't see the output of the task. It was filled during initial
development tests.

Is there a way to see logs of worker processes ? I couldn't find
any. The logs directory of web2py is empty.

[web2py] MongoDB

[José Ricardo Borba]

I'm very busy in these days, but I tried to start a new "installation" from
the ground (to test the TIME issue with Mongodb in pydal #170), but even
without this correction (i.e, with plain web2py clone from github) I
receive the below error message.

I'm simply copy the application folder to the new installation
(side-by-side with welcome and examples). With CLI client (mongo)
everything works fine.

The welcome app works fine.

I see that pydal tries to connect 5 times. The string to connect to mongo
is fine (since is a local install. In production will have an user and a
password too...).

[web2py] cache.redis server unavailable = traceback. Bug?

[Jose C]

Greetings,

I have always assumed that if cache is unavailable, then the fallback is to 
serve the content from original source again (i.e. treat as if key does not 
exist).

I was surprised today when I got a ConnectionError tracebacks when the 
redis server was not online.  Checking the source it appears this is by 
design - it retries connecting 5 times over a total period of 30 seconds 
(!) before giving up and issuing the traceback.

Question:  Is this the default expected behaviour (grind to a halt with a 
traceback) or just an oversight?  My thinking is that cache.redis should 
fallback gracefully and respond as if the key never existed when it cannot 
connect to the redis server.  Certainly it should log a warning or error as 
well, but not bring the site down effectively.

I know I can wrap all cache calls in try: except: blocks to trap for that 
error, however that seems extreme and the more elegant solution would be to 
handle it within cache.redis itself. 

Incidentally, blocking a thread for 30 seconds while waiting for the redis 
server also seems like overkill.  Surely if redis hasn't responded within 5 
seconds max it's time to move on?

Thoughts?  If I'm not missing something I'm happy to open an issue on 
github.

web2py ver: 2.10.4

Regards,
Jose C

Search for SublimeREPL: Web2py {your application name}
It should start interactive console for your web2py application

Re: [web2py] Re: Singletons Save Memory and Time

[Michele Comitini]

if instantiating the object takes time Joe's approach is absolutely correct
IMHO.  One must avoid  caching  per-thread or per-process data in the
singleton unless explicitly managed with proper locking/message passing.
So to speed up more one can use cache.ram or cache.disk or memcache or
redis ... to also cache output, reducing also the impact on db and
rendering as Leonel suggest, while delegating the complexity of managing
context data to web2py caching.

[web2py] Keeping track of connected users (websocket_messaging.py)

[Samuel Sowah]

Hello,
Please if I'd like to keep track of users who are connected to a particular 
group, for example

   $(document).ready(function(){
  var data;
  
$.web2py.web2py_websocket('ws://official-notebook.com:/realtime/mygroup',function(e){data=eval('('+e.data+')')});
   });


so that I can list the connected users, and then remove them from the list 
when they disconnect, how would I achieve that?

 Hi Ramos,

 You should add a web2py application folder to a Sublime Text prokeject
 1. Open Sublime go to the Project menu
 2. Choose Add folder to project option
 3. Browse your web2py application you like to work on

 You are ready to use the W2P plugin

 I am going to make the video tutorial on the weekend and also going to
 update the plugin read with these steps

Re: [web2py] Re: How to add a trailing slash in URL?

[Francisco Costa]

Tx Willoughby,
I've accompished that with 
​​
rewrite ^([^.]*[^/])$ $1/ permanent;


but I don't think is a good solution for a SEO standpoint because the code 
will then have URLs without the trailling slash and every click will be 
redirected to the URL with the slash

Re: [web2py] Re: Sublime Text web2py plugin

[Gergely Orosz]

Once you installed the plugin restart Sublime Text

All prefixed all web2py related command with W2P

commands

[web2py] Re: Linking directly to an uploaded image

[Annet]

In one of my application I store uploaded images in separte folders


in table definitionl:

Field('imageFilename', length=128, writable=False, readable=False),
Field('image', type='upload', requires=[IS_IMAGE(extensions=('gif', 'jpg', 
'jpeg', 'png'), maxsize=(240, 100), error_message='maxWidth is 240 pixels 
maxHeight is 100 pixels. File format: gif, jpg, jpeg, png'), 
IS_LENGTH(48*1024, error_message='File size exceeds 24 KB')], 
autodelete=True),


in function:

folder = 'user' + str(auth_user.id)
db[table].image.uploadfolder = 
os.path.join(request.env.applications_parent, 'applications',
  'dbmodel', 'static', 
'uploads', folder)

form = SQLFORM(table, record, deletable=True, showid=False,
   upload=URL('dbmodel', 'static/uploads', folder, 
args=request.vars.image))
if hasattr(request.vars.image, 'filename'):
form.vars.imageFilename = request.vars.image.filename



In case the image field can be empty I use requires = 
IS_EMPTY_OR(IS_IMAGE(), IS_LENGTH())
and in the function:

if form.process().accepted:
if record and form.vars.image__delete:
file = record.image

os.remove(os.path.join(request.env.applications_parent,'applications',
   'dbmodel', 'static', 'uploads', folder, 
file))
record.update_record(image=None, imageFileName=None)

to delete the image from the folder.
