Re: [web2py] Re: Helper for many-to-many result sets?
Taking this exact example
Foreach movie in movies
print movie.title
foreach stars in movie.stars
print star.name
I guess `movie.stars` is a list:string field?
if so.. there's one-liner solution
table = TABLE(*[TR(TD(movie.title), TD(UL(*[LI(star.name) for star in
movie.stars]))) for movie in movies])
if db.stars has a list:reference to movies
table = TABLE(*[TR(TD(movie.title),
TD(UL(*[LI(star.name) for star in
db(movie.id.belongs(db.stars.movies)).select(db.stars.name)]))) for movie
in movies])
or with a subquery (for each loop iteration)
table = TABLE(*[TR(TD(movie.title),
TD(UL(*[LI(item.stars.name) \
for item in *db((db.movies.id ==
db.stars.id) \*
* (
db.movies.id == movie.id)).select(db.stars.name)*]))) \
for movie in movies])

There may be a more elegant way to do this, but it does work.
Be sure to select the movie id in your query.
Then you can do something like this:
rows = db(query).select(.) #whatever you're doing
trows = []
stars = []
for i, r in enumerate rows:
stars.extend([r.stars.name, BR()])
if r.movie.id != rows[i+1].movie.id or i+1==len(rows):
trows.append(TR(
TD(r.movie.name),
TD(stars), # Other stuff from the row follows
)
)
stars=[] # Reset the stars list
return(TABLE(*trows))

I have a movie table that has a many-to-many relationship with a person

A simplified version of my model:
db.define_table('movie',
Field('title','string'),
db.define_table('person',
Field('name', 'string', unique=True),
db.define_table('star',
Field('movie_id', db.movie),
Field('person_id', db.person),
I am able to create a select that joins the three tables and produces a
result with all the data I need.
It's easy to iterate through the result and produce something akin to
this:
Movie Title Star 1
Movie Title Star 2
Movie Title Star 3
What I want is:
Movie Title 1
Star 1, Star 2, Star 3
Movie Title 2
Star 1, Star 2, Star 3
Programmatically, I'd like something like:
for each movie in rows
h2move.title/h2
ul
for each star in movie.stars
listar.name/li
Before I write a function to pre-process the result, can someone tell me
if there is a helper for producing a result of this kind?
This thread addresses the same issue -
https://groups.google.com/**forum/?fromgroups#!topic/**web2py/GQsMt4qvqSshttps://groups.google.com/forum/?fromgroups#!topic/web2py/GQsMt4qvqSs
- but I was unable to discern the solution the question asker had
produced for himself, the key to which was this:
web2py automatically add the many-to-many sets to an instance with the
same name of the relation table
I do not know what that means.

Re: [web2py] Re: Helper for many-to-many result sets?
I guess you can also do: table = TABLE(*[TR(TD(movie.title), TD(UL(*[LI(star.name) for star in * movie.stars.select()*])) for movie in movies]) when a table is referenced by another, he gets a DAL Set object with the referer name. movie.*stars *will be a DAL Set. which has *select, update, delete* methods But it will only happens depending on your model and relations definition. Can you share your model for those 2 tables?

[web2py] Re: Sending emails with background queue problem
The problem sums up to: I expect when committing that something like saving a file happens...everybody, and I mean everybody trying to access that file later would read the same thing. SQlite, MSSQL, Postgresql, Oracle adapters work this way, and I assume also mongo and couchdb. I tried to read the PEP for the DBAPI and saw no explicit references to what committing should do in reference to a multiprocess environment (i.e. if commit should save the changes and make them available for other processes). However, I'm not a python guru to rule that out, I'm just saying that from a DAL point of view having to commit before reading to see records changed/inserted by other processes is required ONLY from mysql.

[web2py] web2py for embedded hardware control
Hi all, I'm fairly new to web2py and python, but I'm trying to build a 'proof of concept' system to demonstrate how one of our products might work. The system consists of an embedded Linux board and an RS232 serial digital compass. The system will read the orientation from the compass and light a few LEDs as well as an audible tone to point a user in the right direction. The device will also host a small web server running web2py so that people can log on and view the real compass outputs - possibly an animated graphical display if i get that far... So really i just need some advice about the best architecture to get me started. Should I build everything into web2py - will it handle worker threads for reading serial port etc, will it handle the LEDs/tone if no http users are connected? Should I build a stand-alone python 'service' that handles the hardware interface - web2py can then read the results for the web elements? Would this use JSON, SOAP etc? Any help would be gratefully appreciated. Sam --
[web2py] Re: redirect results in invalid request.
Note, the signature of the URL() function is URL(a, c, f, r, args, vars,
...). So, in your first example, it interprets addressbook as the
application and request.args(0) as the function, and in your second
example, it interprets request.args(0) as the request object (which is why
you get the error about a str object not having an application
attribute). So, in general, it is best to specify args and vars as
keyword arguments -- if you want to specify them as positional arguments,
you have to fill in all four preceding positional arguments as well.
Also, note that regarding the first three arguments, URL() is smart -- if
you only specify two positional arguments, it assumes they are c and f
rather than a and c, and if you only specify one positional argument, it
assumes it is f rather than either a or c (if a and or c are missing, they
get filled in with the current application and controller).

*Why this? just to let users to personalize the message string more easily.*
Example:
auth,messages.verify_email = ('Here I put my very long html code'
'I can write texts '
'I can put a tutorial '
'I can put an user agreement'
'ans so the final link'
' Click on the link'
' http://%(host)s/%(url)s/%(key)s
'
to verify your email')
*or even...*
auth,messages.verify_email =
template.render(my_verify_email_template.html, {mycontext: myvalues})
Customizing this message sin the current way is very difficult and lead on
errors because of string interpolation being done on the time of definition.

You need to replace the string

'Click on the link ...'
in auth.messages.verify_email with the proper complete URL of the
action verify_email.
For both verify_email and reset_password:
Should I replace
'Click on the link http://'
With:
'Click on the link http://myserver.com/myapp/'
Or with:
'Click on the link http://myserver.com/myapp/defa**ult/user/verify_email'
My guess is the first, but because the book says proper complete URL, I

[web2py] Auth and Model less
Hello again, I'm having some trouble with my model less aproch with auth module. I've put him on a separeted file on modules folder, and, when needed, I import it as follows: modules/web2py/auth.py: auth = Auth(db, hmac_key=Auth.get_or_create_key()) controllers/tracking.py: from applications.main.modules.web2py.auth import auth But some times (its not every time) when I try to loggin, the form just don't validate and don't pass through the login/password for checking (I'm also using the default login form from docs). Maybe this have some relation with imports being done only once on appengine? And, if is it, what can I do about (since not every page on my app needs auth) Thanks --

auth,messages.verify_email = ('Here I put my very long html code'

'I can put a tutorial '

auth,messages.verify_email =
template.render(my_verify_email_template.html, {mycontext: myvalues})
But can't you already do either of the above? As long as the resulting

no? In the first case, for example, you could do:
auth.messages.verify_email = '''here I put my very long html code

and so...the final link
Click on the link
http://%(host)s/%(url)s/%%(key)s

Which will yield:
'here I put my very long html code\nI can write text\nI can put a
tutorial\nand so...the final link\nClick on the
link\nhttp://mysite.com/default/user/verify_email/%(key)s\nto verify your

[web2py] Re: comparing responding arg with request.args(0)
Hi Anthony,
In a request I use request.args(0) to determine the response, for instance
http://127.0.0.1:8000/bootstrap/calendar/eventlist/6
In this case 6 is the argument of the response, when the visitor changes
this argument manually and requests
http://127.0.0.1:8000/bootstrap/calendar/eventlist/28 I need a way to
determine that the visitor did change the argument, for node 6 has access
to eventlist but user 28 probably not. In that case I'd like to route to a
router function which determines what to do.
I thought something like storing session.response=request.args(0), in this
case session.response=6 and comparing session.response!=request.args(0) in
this case 6!=28 and the
redirect(URL('addressbook','router',args=request.args(0) in every function
would solve my problem.
I'd like to know if this is the way to go or whether there is a better way
to solve this problem?
Kind regards,
Annet

[web2py] Re: Book clarification regarding verify_email reset_password
Thanks for the info, everyone. I thought the example might look OK as is,
but i really don't understand everything the way you folks do.
I have a bit of a follow up question. The ENTIRE example *seems* to imply
that the following lines are *NEEDED* to enable email verification:
auth.settings.registration_requires_verification = False
auth.settings.registration_requires_approval = False
auth.settings.reset_password_requires_verification = True
Is that true?
I want, at least i think i want:
registration_requires_verification = True
BTW there's a sample code bug i found in the same section. Replace the
double quote () in the following with a single quote (') and it compiles.
auth.settings.register_onaccept.append(lambda form:\
mail.send(to='y...@example.com',subject='new user',
message=new user email is %s'%form.vars.email))
Thanks for the help. And thanks for the great documentation and for caring
about it.

For both verify_email and reset_password:

My guess is the first, but because the book says proper complete URL, I am

This is what I love about web2py.

where
min is minimum length of the value
special is the minimum number of required special characters special

upper is the minimum number of upper case characters

[web2py] Re: comparing responding arg with request.args(0)
OK, I guess it's a nomenclature issue -- args are part of the URL requested
and therefore only part of the request, not the response. Rather, you need
to validate whether the request arg is valid for the particular user. Of
course, you can store the user's node id in the session, but if you are
then going to check it against request.args(0) on every request, you might
as well get rid of the node id from request.args altogether and simply
store the node in the session instead. So, wherever you are no using
request.args(0), you would instead reference something like session.nodeID.
If session.nodeID doesn't exist, you then redirect to your router so it can
be set.

[web2py] Re: comparing responding arg with request.args(0)
So, wherever you are now using request.args(0), you would instead
reference something like session.nodeID. If session.nodeID doesn't exist,
you then redirect to your router so it can be set.
That's what I've been experimenting with the last couple of days, it works
fine for the single page views, however, nodes can have sites with multiple
views, and different nodes can be visited in more than one browser window.
In case of sites with multiple views, the router function always routes to
an index function, in which I build the menu for the current node and store
it in session[id], this is part of the code:
aboutnav=db((db.NodeNav.nodeID==id)(db.NodeNav.navID==db.Nav.id)(db.Nav.navbarID==ABOUTNAVBARID)).select(db.Nav.ALL,db.NodeNav.ALL,orderby=db.Nav.position).as_list()
if aboutnav:
session[id].aboutnav=True
for r in aboutnav:
if r['Nav']['id']==ABOUTNAVID and r['NodeNav']['frontend']:
session[id].site_menu.append([T(r['Nav']['name']),False,'#'])
elif r['NodeNav']['frontend']:
session[id].about_dropdown.append([T(r['Nav']['name']),False,URL(r['Nav']['frontendcontroller'],r['Nav']['function'],args=id)])
f=r['Nav']['function']
if f:
session[id].f=True
The last three lines, are what I am experimenting with right now. Every
function that is referenced by a menu item starts with:
def eventList():
f=request.function
if not len(request.args):
redirect(URL('addressbook','router'))
elif not session[request.args(0)]:
redirect(URL('addressbook','router',args=request.args(0)))
elif not session[request.args(0)].f:
redirect(URL('addressbook','router',args=request.args(0)))
else:
So far, this seems to solve the problem.
Is it possible to put these conditions in a separate function, and call
that function from every function that needs it? Something like:
def access():
f=request.function
if not len(request.args):
redirect(URL('addressbook','router'))
elif not session[request.args(0)]:
redirect(URL('addressbook','router',args=request.args(0)))
elif not session[request.args(0)].f:
redirect(URL('addressbook','router',args=request.args(0)))
else:
return True
def eventList():

The data which can be accessed via oauth2 will differ from provider to provider, but probably some basic identification data can be obtained. It is not clear to me which data can be obtained, how the link account in web2py can be setup, what is the role of the authentication token, whether the authentication token can be saved for later use, how long is the authentication token valid, and lots of other open questions.

My goal is to have a basic demo of how to integrate a OAuth2 library with web2py, preferably this sanction library, since it seems that lots of providers are supported out of the box, and that more can be easily added.

In practice this change will probably not affect anybody because none of the services sends any information stored by auth_user. Yet, please check it.

[web2py] Re: comparing responding arg with request.args(0)
So, wherever you are now using request.args(0), you would instead reference something like session.nodeID. If session.nodeID doesn't exist, you then redirect to your router so it can be set. That's what I've been experimenting with the last couple of days, it works fine for the single page views, however, nodes can have sites with multiple views, and different nodes can be visited in more than one browser window. Different browser windows should share the same session (though not different browsers). Is it possible to put these conditions in a separate function, and call that function from every function that needs it? Something like: Yes, I was going to suggest that. Anthony --

The view does not see objects created in the controller unless they are

can do:
def view_func(arg1, arg2):

return something
def index():
return dict(message='Hello World', func=view_func)
And in the view, you could call:
{{=func(arg1='this', arg2='that')}}
Note, functions defined in controllers are by default exposed for access
via HTTP requests unless they take arguments or start with a double
underscore, so be careful not to expose a function intended only for
internal purposes.
Another option is to define the function in a model file, in which case it
will be available in all views without needing to be passed from the
controller. You could also define the function in a module and import it in
the view.

[web2py] Re: howto subset a select element
You can't do that all at once when you respond to the initial request
because it depends on user input, so you have to populate the second select
via Ajax on the client side once the first selection is made. See
herehttp://stackoverflow.com/questions/8146260/best-practice-for-populating-dropdown-based-on-other-dropdown-selection-in-web2p/8152910#8152910for

That's perfect. Thanks for your help guys.
On Monday, 13 August 2012 02:38:17 UTC+1, Anthony wrote:
Note,
{{=LOAD('default','myaction', ajax=True)}}
is just a helper that produces the following HTML:

web2py_component('/test/default/myaction','c784764977599');
//--/scriptdiv id=c784764977599loading.../div
So, you can trigger a component loading in a div by manually calling the
web2py_component() function in the browser and specifying a target div.
Note, if you want the component to load initially via LOAD() and then make
subsequent calls to web2py_component() to load other content into the div,
you can specify your own id for the div instead of having LOAD() generate a
random id as above:
{{=LOAD('default','myaction', ajax=True, target='mydiv')}}
yields:
script type=text/javascript!--
web2py_component('/test/default/myaction','mydiv');
//--/scriptdiv id=mydivloading.../div
Bruno mentioned the use of web2py_ajax_page() -- that function is
ultimately called by web2py_component(), so either will work, but
web2py_component() is probably easier.

I am looking how i can doing some humedity graph from my database like: http://www.google.cl/imgres?imgurl=http://bfinet.es/objects/300_19_1511558087/grafico-humedad.jpgimgrefurl=http://bfinet.es/Sonda%2BTemperatura%2By%2BHumedad-300.htm?sid%3D86888e016e7af58b05e6bd8071640e45h=395w=650sz=39tbnid=cyGO1-CPIR49ZM:tbnh=74tbnw=121prev=/search%3Fq%3Dgrafico%2Bhumedad%26tbm%3Disch%26tbo%3Duzoom=1q=grafico+humedadusg=__5kwEzOircYj92GYI4L0ROPQb_gs=docid=DFD_8y7rDNLQmMhl=es-419sa=Xei=Fc0qULSCFKfy0gHIx4DADAved=0CE0Q9QEwAAdur=221 X=Time (0 - 24 Hrs) Y= % humedity I hope you could give me some idea or how i can do.

[web2py] Re: Scheduler: help us test it while learning
Niphlod- has there been any discussion about a param for clearing out old records on the runs and tasks tables? Maybe a retain_results or retain_completed value that specifies a period for which records will be kept?

Re: [web2py] Re: Install in hostgator
Hi Brian,
I tried a similar setup but I wasn't able to run it... Were you able to run
web2py in hostgator?
When I try to run it from ssh I get:
lance...@lancesegols.com [~/public_html/lancesegols.com]# python web2py.py
web2py Web Framework

use kill -SIGTERM 31355 to shutdown the web2py server
Fatal Python error: Couldn't create autoTLSkey mapping

Not sure what is wrong... I have put web2py source inside public_html is it
the right path?
My dispatch.fcgi
#!/home/lanceseg/local/bin/python
import sys
from flup.server.fcgi_fork import WSGIServer
import gluon.main

## or
# application=gluon.main.wsgibase_with_logging

My .htaccess:
AddHandler fcgid-script .fcgi
Options +FollowSymLinks +ExecCGI
RewriteEngine On
RewriteBase /
RewriteRule ^dispatch\.fcgi/ - [L]
RewriteRule ^(.*)$ dispatch.fcgi/$1 [L]
Not usre what is wrong but there is not a good tutorial for hostgator.
Regards,
Tito

Yep it'll work similar on hostgator - tried it out a few months back just
to see if I could get it working, haven't actually deployed anything useful
but it appears to run ok. I recall that an appropriate version of Python
flup were already installed on my hostgator shared box. I did my install of
web2py into a subfolder rather than the site root which probably made
things harder. Here's that I can quickly grab from my setup, sorry didn't
take detailed notes :(

Re: [web2py] Re: Scheduler: help us test it while learning
Nope, that goes wyyy over the scheduler responsibility. Prune all records, prune only completed, prune only failed, requeue timeoutted, prune every day, every hour, etc, etc, etc these are implementation details that belongs to the application. We though that since it is all recorded and timestamped it's a matter of: timelimit = datetime.datetime.utcnow() - datetime.timedelta(days=15) db((db.scheduler_task.status == 'COMPLETED') (db.scheduler_task.last_run_time timelimit)).delete() that is actually not so hard (scheduler_run records should be pruned away automatically because they are referenced) (I like to have a function maintenance fired off every now and then with these things on it.) 2012/8/15 Yarin ykess...@gmail.com Niphlod- has there been any discussion about a param for clearing out old records on the runs and tasks tables?

[web2py] Re: HTTPS and the Rocket server?
yes. Try web2py.py -h for options. you can use -c and -k if you just want https.
