Well, I'm relatively new to Python and don't know all the ins and outs. It 
was more of a guess. Are you really trying to insert raw numbers? An RTF doc 
is text after all.

So in other words I can't append raw integer data, I have to append values of

Oh, shoot, I figured that might be the answer but only had

I ended up writing a function since it seems assignments in lambdas are 
difficult. I tried setattr() and a nested function to no avail. Any ideas?

You probably need to do:

There are two examples for "radio" types. I suppose the other one is

[web2py] Re: squeeze + Apache2 = lots of RAM

[VP]

I definitely agree that there should be a setup guide / script for
nginx/wsgi for web2py.

That said, I'm not giving up on Apache yet.  I think I found out what
the culprit to this high usage of RAM for Debian squeeze.

Short answer.  I think this will fix it:

sudo apt-get install apache2-mpm-prefork

===
Long answer.  I think it's more complicated that I understand, but my
understanding is that this has to do with how Apache2 handles multi-
processing.  Apparently, there 3 modules related to this: (1) prefork,
(2) worker and (3) event.   You can install each with apt-get (e.g.
apt-get install apache2-mpm-worker or apt-get install apache2-mpm-
event).

I think Debian 6 (squeeze) has "worker" as the default multi-
processing module.

Prefork is the non-threaded, traditional, tried-and-true mode of
Apache2.  Worker is the multithread version and it consumes a lot of
RAM.   Event is based on Worker.  It takes as much memory as Worker,
is experimental and is supposed to work well with applications having
lots of requests.

In my application, Worker consumes lots of RAM, but doesn't appear to
have any benefits.  Event actually produces the best result (the most
number of requests/sec and the lowest time per request), while
consumes as much RAM as Worker.

So, I think if your RAM is abundant, I'd suggest that you try the
apache2-mpm-event module.  If not, try apache2-mpm-prefork module.




While I am playing with these modules, I also discovered that with
web2py having more processes is much better than having more threads.
My current configuration of wsgi is processes=5 and threads=1.  This
works much better than for example processes=1 and threads=15 (which I
think is the default configuration).

Massimo might want to play around with this and might want to change
the official Apache guideline to reflect this.



With prefork, 5 processes, 1 thread, I'm quite happy.  Things are
quite snappy, and RAM are well under control.

So, until the next headache, there it is.

Re: [web2py] Re: File Upload and save to DB

[Ismael Alejandro]

Hi again, working with the original section, now I have this:


- On a CLIENT computer, I generate the INI file with this structure:
[Room]

name = room1
color = red
size = big

- I send it by FTP to the computer where web2py is running

- I have this script to parse and process the INI files on the server:

import os
import ConfigParser
import traceback

_configDir = "_configuploads"

def parse(filename):
try:
config = ConfigParser.ConfigParser()
print filename
config.read(filename)
rooms = config.sections()
print "Rooms: %s"%rooms
dictio = {}
for room in rooms:
dictio[rom] = {}
options = config.options(room)
print "Ops: %s"%options
for option in options:
dictio[room][option] = config.get(room,option)
print dictio
return 0
except:
print "Something failed!"
print traceback.format_exc()
return 1

objects = os.listdir(_configDir)

for item in objects:
fitem = os.path.join(os.getcwd(),_configDir,item)
parse(fitem)
print "="

this is a script placed on the root web2py directory (I'm using the source
version on a Windows PC)

So with this script I parse the INI and put the info in to a dictionary
called "dictio", now,  how could I use this dictio info for saving it in the
DB. Keys are generic and standard so they are the fields names. Values are
the Values :P


I'm not expert with python, in fact all above is made with some code of

Thanks! I hope you can help me!

Re: [web2py] Re: new URL router use cases

I think I'm in agreement. App-specific routing should be controlled at the

updates.

Re: [web2py] Stopping Dev server

[pbreit]

I guess it is tricky. I was concerned about my crons causing 5 python 
processes to start every time I restarted web2py. The answer is probably not 
that simple. When you're in dev mode and only using Python with web2py, 
there might be a solution. Otherwise, I suppose you have to be careful about 
which Python threads you kill.

Re: [web2py] Stopping Dev server

I've been wondering about it too, and for the same reasons, wouldn't be
possible to set a -reload parameter on development mode? or just a mode

Sorry perhaps I don't express myself correctly, I'm not saying this is a bug
or I can't do with the current way. I'm only saying that I think better if
there are something like that in app level. It's an idea. Main routes.py to
control things up to the application, and the rest by the application.

Main: routes.py:

Domain Application

www.domain1.com domain1
www.domain2.com domain2

Aplication:  applications/domain1/routes/routes.py:

/favicon.ico /static/favicon.ico


Final result: routes.py + application/routes.

/domain1/static/favicon.icowww.domain1.com/favicon.ico


In my experience in production I never share things between application or
statics. I Think in the 97% or more of the application developed, to be in
production are completely independant from the others app.

[web2py] Stopping Dev server

[David Warnock]

Hi,

Just wondering if the admin application could off the option to restart the
development webserver.

When running in development mode using "python2.5 web2py.py" there are a few
times when the server needs to be stopped or restarted (install upgrade,
adding routes.py).

I wondered whether it would be possible for the admin application to at
least do a clean shutdown to save me needing to open an extra terminal and
paste the "kill -SIGTERM " command. I even wonder if it would be
possible to go one step further and automagically restart web2py

Obviously this is protected so it only works if logged into admin and
running web2py directly (or maybe the GAE server as well) rather than using
another server.

[web2py] Re: auth_user field default to other auth_user field?

[Massimo Di Pierro]

default does a take a lambda but one without arguments, because the info is 
used before the form is submitted so there is no data (r).

[web2py] Re: auth_user field default to other auth_user field?

[pbreit]

I don't think that's quite the behavior I'm looking for. I want it to 1) 
default.paypal_email=email upon registration and 2) both email and 
paypal_email editable independently in Edit Profile.

So this would be perfect:
 
 Field('paypal_email', length=128, default=lambda r: r.email))

But "default" apparently doesn't take a lambda.

Re: [web2py] Re: new URL router use cases

[pbreit]

+1 for a move towards routes default "on" and primarily controlled at the 
app level. But I do recognize there is an issue about what file should come 
in the main distribution and how to avoid it being overwritten with updates.

The default files could duplicate the current default functionality for 
explicitness.

[web2py] Re: squeeze + Apache2 = lots of RAM

[VP]

You can stop and restart apache to confirm that it takes that much
RAM.

If you do a stress test, you'll probably see that it will eat all your
RAM.

Right

But I´m building the table in the controller so I guess I can´t use 
{{= }}   ?



Kenneth



It is the watchers[check_date] that holds the text that should be sent
to the javascript but nothing is sent.

I have verified that the variable contains text and if I define
_onmouseover="displayText('info', 'test_text')",

it works.

Re: [web2py] Re: new URL router use cases

Tom, you cannot mix usage of the parameter-based and pattern-based routing 
systems, even if one is in the global routes.py and one is in an 
app-specific routes.py. You have to pick one system or the other, for now 
anyway.

Re: [web2py] Re: new URL router use cases

[Tom Atkins]

Thanks for this suggestion Massimo - it's the closest to what I'm looking
for.  I've tried to get it to work but no joy.

I've changed my global routes.py to use parameter based routing sand put the
first part of your code in the application specific routes.py.

I've then put the 2nd part of your code into the default controller.  But if
you go to:

myapp.com/Supersite/users

I get:

invalid controller (Supersite/users)

I've tried but can't figure out a solution...

Both versions of routing work the same way, in principle. You need a base 
(root) routes.py so that the router can figure out the application (otherwise 
it wouldn't know which app-specific routes.py to use). The rest of the routing 
information can be in each applications root folder.

The new router's syntax makes it pretty easy to have all the routing in the 
base routes.py, though, since each app can simply have its own routing dict.

Hi,

With both systesms, you can put a routes.py file in the application folder, 
but at least with the older system, for that to work, you also need a 
routes_app entry in the main routes.py file -- is that what you're saying 
you don't want? In other words, you want no dependency on any central 
routes.py file? Perhaps Jonathan can verify, but I think that may be

You can do this with the new router if you make post the default function of 
the blog app, and create a list of functions in blog/default. Something like 
this:

routers = dict(

blog = dict(
default_function='post',
functions=['index', 'user', 'post', 'whatever'],
),
)

You'll need to parse and validate the args in default/post.

By specifying a list of functions in the default controller, you're telling the 
router that it can unambiguously omit the 'post' name if there's no conflict. 
So with the router above, a URL like /blog/default/post/index would *not* be 
shortened to /blog/index, because that would conflict with the function named 
'index'.

This got rid of the errors. Thanks Massimo.

The only thing I added was a try-except block on search() when no people 
were found. The simpler version of the query also restricted the search 
somehow (had to search first name and last name with the right 
capitalization) but I guess that's the trade off. Will look for a way to 
improve the search with the GAE caveats in mind.

For example I have a blog application with this url

I can short to this:

http://www.mysite.com/blog/2010/10/10/my-article

with this one route:

(r'.*:/blog/(?P(19|20)\d\d[- /.](0[1-9]|1[012])[-

 I think this is something Massimo might want to spend sometime
 thinking about.

 As I understand it, because of "exec", controllers are called *after*
 the request arrives.  This allows web2py to do a few interesting
 things that other frameworks can't.

 On the other hands, this is an example that shows an advantage of
 being able to manipulate controllers (concisely) *before* the request
 arrives.

 I found myself constantly type checking controller arguments (e.g.
 making sure an "id" is a number).  This is another example where being
 able to specify a certain syntax to the URL is very helpful.

Re: [web2py] Re: new URL router use cases

[Tom Atkins]

The problem for me is not being able to mix the new parameter-based routing
with the pattern-based system (my regex skills are not good enough to make
the patten system do what I want) .

Is it possible to have parameter system in the global routes.py and then
pattern system in the app-specific routes.py?  That would solve my issues!

A web2py model gets run on every request, so something like this should work OK 
(I think). Is it possible that session.order is there, but not recognized as 
Order? What happens if you test for: session.order is None?

Re: [web2py] Re: Class in the session

[Rui Gomes]

Regarding storing the class in the session is not a problem that work fine
for me(need to be careful some things can't be pickel), the problem is
re-write it at each call,

I already try something similar to

order = session.order or Order()

I did,

if not isinstance("session.order",Order):
session.order=Order()

that didnt work session.order look always like empty to the validation,
since a python module just get imported once, if I move the class out of the
models in the web2py and put it in a file and imported something

from Order import *

Maybe thats work.

Any other ideas how to do this?


BTW: Thanks for the help if in the mean while i figure this one out I will
post it here.

Notice that the routing mechanism you're talking about doesn't depend on the 
routing information being distributed as controller decoration; they can be 
presented in a table instead. In fact, putting them in a table has advantages 
over the decorator approach, in that a) you can see the whole routing policy in 
one place, and b) you can explicitly specify the order of evaluation.

Checking controller arguments is important, since they are, after all, user 
input and not trustworthy. And there's something to be said for checking them 
at the controller/function, since you're in a position to give more informative 
error messages if something is wrong. 

If you're using web2py forms, then the validators serve this purpose. If you're 
not, you can use the validators on their own.

Re: [web2py] Re: new URL router use cases

[Anthony]

I believe this is already possible, no?
 
The book describes app-specific routing for the old system: 
http://web2py.com/book/default/chapter/04#Pattern-Based-System
 
And  for the new system, the router.example.py file (
http://code.google.com/p/web2py/source/browse/router.example.py) mentions 
you can have an app-specific router in applications/app/routes.py.

Depends on what you mean by parallel.

In normal terms, that is if you are not depending on some state or
property that requires use of artifically managed parallel
transactions, the answer is yes.

Why not just test and see?

There are practical limits. A severe practical limit comes form the OS
overhead in using a thread for each web2py request to a controller
function.

The mentioned session and database locking issues are of course also
relevant. Just beacuse a session or database locks occurs does not
mean the request fails. They are just one more place queues or locks
occur. IO (input-output) OS (operating systems) queues or locks are
very common and are hidden.

I hope this adds a bit more insight.

 I don't think the xx part of 1.xx.y is to be interpreted as a decimal with 
a maximum of 99 -- I think it's just the number of releases within the 1.0 
series (so, can go over 99).

I'd like to know a little more as well. It seems to me that since sessions are 
relatively transient (you're not going to preserve sessions if you move web2py 
elsewhere), the path to the class isn't going to change between session 
accesses.

Re: [web2py] Re: new URL router use cases

[Martín Mulone]

I really want to see routes in the application folder. Routes in the past
was hard to follow, now I think the work of Johnatan make it more easy. But
when you have many applications, the routes for all is a bit messy. I don't
know if this can be done:

For example a simple case:

Main routes.py:
---

Domain Application
-
www.domain1.com domain1
www.domain2.com domain2



Aplication:  applications/domain1/routes.py:
---


[routes In]
In Out
--
/favicon.ico /static/favicon.ico


[routes Out]
In Out
--
default/index /

I think with that code, every request is just going to create a new Order() 
object and write it to session.order (replacing any existing session.order). 
If you want to add items to the order and maintain those items in the 
session in between page requests, then I would think at each request you 
would have to first check to see if there is an existing order stored in the 
session, and if so, retrieve it from the session, update it, and then write 
the updated order back to the session. Maybe something like:
 
order = session.order or Order()  # Note, if session.order doesn't exist, it 
will return None, and a new Order() will be created.
[insert code to update the order]
session.order = order
 
There is an additional problem, though. According to Massimo, web2py cannot 
store instances of classes in the session: 
https://groups.google.com/d/msg/web2py/dmN54cpMuXo/lufvxmaQMLUJ. Perhaps 
Massimo has more to say regarding this example.
 
Finally, I think new-style classes are generally recommended, so you would 
do 'class Order(object):' instead of 'class Order:'.

[web2py] Re: new URL router use cases

[VP]

Noticing the version of web2py keeps interestingly increasing to 2.0,
I think this is something Massimo might want to spend sometime
thinking about.

As I understand it, because of "exec", controllers are called *after*
the request arrives.  This allows web2py to do a few interesting
things that other frameworks can't.

On the other hands, this is an example that shows an advantage of
being able to manipulate controllers (concisely) *before* the request
arrives.

I found myself constantly type checking controller arguments (e.g.
making sure an "id" is a number).  This is another example where being
able to specify a certain syntax to the URL is very helpful.

[web2py] Re: new URL router use cases

Can't this be done in web2py with something like this?

yoursitename = request.args(0)

Good catch, Kenneth. Note, if he's following the example in the book, then 
he does need the HTML and BODY tag -- the book instructs you to overwrite 
the existing content of index.html with the above code (i.e., it does not 
extend layout.html).

You are right. It actually looks like the change from app.yaml to 
app.example.yaml was made prior to the 1.94.1 release.

This says all, I guess you have copied the whole text even the row numbers.

You don´t need a HTML or BODY tag, the /views/default/index.html should 
only contain


{{=message}}


Row number is shown in the manual only so that it is easier in the text 
to explain things. Row number are not used in python.

I was simply doing what the manual told me to do - even if I

Note, if you're on p. 88 doing the "Say Hello" example, you have
not yet gotten to the stuff about using layouts and {{include}} --
that stuff starts in p. 92 in the "Let's Count" section. Because
ch. 3 is tutorial style, explanations tend to be limited to what's
going on with the immediate example, so you learn the details
progressively. On p. 87, you learn that returning a string from
your controller function simply sends the string as is to the
browser (it's not inserted into any view/template). On p. 88, you
learn that if you return a dictionary (instead of a string),
web2py looks for the associated view file (and uses the generic
view if it can't be found). And then on p. 92, you learn about
extending a layout template.
I think the instruction about editing index.html on p. 88 could
probably be improved. First, where it says "the new file
associated with the action", it should probably say "the view file
associated with the action". Second, it should probably explicitly
say to completely replace the existing index.html content with the
example code to avoid confusion. I'll make some edits to help clarify.
As for the numbers above and below your message, I can't explain
that. Are you sure your index.html includes only the text from p.
88 and your controller is just:
def index():
return dict(message="Hello from MyApp")

[web2py] Class in the session

[NewBeen]

Hello guys,

I have this class in a model,

Class Order:

def __init__(self):
self.basket={"product":{},"quantity":{}}

   def addProduct(self, Item):
   self.basket["product"]["name"]=item["name"]


session.order=Order()

So far so good, but when I execute this, the class is always been
initialize, so I lose my basket between pages...
Any ideas how can I fix this, if I put a class in a module and import
it will it fix it?

To know if it exist or not you must have condition in the form of a
query. You can do

if not db(query).update(...): db.mytable.insert(...)

where ... is the field='value' list.

[web2py] Re: Running the web2py mini-fb clone demo (additional info and some questions)

[Massimo Di Pierro]

I apologize. I thought I made all required changes but I missed one:

In controller replace:

friends = db(User.id==Link.source)
(Link.target==me).select(orderby=alphabetical)
requests = db(User.id==Link.target)
(Link.source==me).select(orderby=alphabetical)

with:


friends = db(Link.target==me).select()
requests = db(Link.source==me).select()

and change the friends.html view into:

{{extend 'layout.html'}}
Friendship Offered

  {{for friend in friends:}}
  
 
{{=A(name_of(db.auth_user(friend.source)),_href=URL('wall',args=friend.source))}}

{{if friend.accepted:}}accepted{{else:}}accept{{pass}}
   deny
  
  {{pass}}

Friendship Requested

  {{for friend in requests:}}
  
 
{{=A(name_of(db.auth_user(friend.target)),_href=URL('wall',args=friend.target))}}

{{if friend.accepted:}}accepted{{else:}}pending{{pass}}
remove
  
  {{pass}}


This is because GAE cannot do joins.

I also think that on GAE the current Query

query = reduce(lambda a,b:a&b,
   [User.first_name.contains(k)|
User.last_name.contains(k) \
for k in tokens])

is too complex and should be

query =
(User.first_name==tokens[0])&(User.last_name==tokens[1])

[web2py] Running the web2py mini-fb clone demo (additional info and some questions)

[Arbie Samong]

I actually tried the tutorial posted here:

http://blip.tv/file/4912976


and here are some information that wasn't mentioned but might be helpful for 
absolute beginners like me:

   - 
   
   You must first register with janrain and take note of the application 
   name
   - 
   
   In models/db_janrain.py, you need to set domain to the application name 
   you registered with. In the tutorial it is set to web2py. It is 
   https://blabla.rpxnow.com/, where blabla is the applciation name.
   - 
   
   The file janrain_api_key.txt will contain only the secret api key, which 
   you can see in the janrain dashboard.
   - 
   
   The web2py source does not have app.yaml. So you copy the one in 
   google_appengine/new_project_template over to web2py/.
   - 
   
   Edit the file and set the application (first line) to the one you 
   registered with in app engine. Then set script to gaehandler.py (under 
   handlers)
   - 
   
   When running the local app engine instance for the first time to build 
   indexes, be sure to change the url in models/db_janrain.py from 
   localhost:8000 to localhost:8080. If you don't it will redirect to the 
   web2py instance instead of the app engine instance, and the indexes will not 
   be built causing an error when running it in appspot.com
   - 
   
   When deploying, appcfg can be found under the google_appengine/ folder, 
   so just copy the full path.
   

Now, for the question. The friends and search pages do not work when 
deploying on GAE, both on localhost:8080 and on the real server. It works 
fine when using the web2py server but not on the GAE. My best guess are 
database issues, since GAE might not be supporting the db calls used in the 
tutorial. The errors are:

[web2py] Is it possible to update or insert object to database in one command?

[Sergey Ozhigin]

Hello,

Is it possible in web2py to update or insert object (if doesn't exist)
to database in one command?

Does anybody know an answer?

[web2py] Re: Problems with Google App Engine

[Arbie Samong]

I encountered the same error because I tried to point the
handler.script field in app.yaml to web2py.py. I changed to
gaehandler.py and it worked.

So in app.yaml instead of -

handlers:
- url: .*
  script: web2py.py

I used -

handlers:
- url: .*
  script: gaehandler.py

Hope that helps.

Regards,
Arbie

[web2py] Re: Converting legacy MySQL databases to web2py DAL

[fib]

OK all I feel quite stupid
I think I need the ABC of running this
I have placed the file in a location where I know where it is and it
can be seen in the web2py list
I have tried putting the call into shell and into a web2py app
I have used IDLE  (python) and have tried shell on web2py
I believe mysqldb is meant to come with web2py so I dont believe I
need that ?

what do I actually type and where to call this and get it to output

Newbie needs hand held - apologies
thank you in advance


Oh and read chap on DAL - good stuff bought the book. I just think I
have a fundamental misunderstanding of what to put where and i will
think it was easy when I get it 

thank you all in advance and for patience

[web2py] Re: Running the web2py mini-fb clone demo (additional info and some questions)

[Anthony]

Thank you. This is helpful.
 
Note, the web2py source *does* come with a GAE app.yaml file -- it's in the 
root web2py/ folder (along with queue.yaml), as explained in the book: 
http://web2py.com/book/default/chapter/11#Configuration
 
Actually, in the current development version, app.yaml and queue.yaml have 
been replaced with app.example.yaml and queue.example.yaml so they don't get 
overwritten upon web2py upgrade. See this thread: 
https://groups.google.com/forum/?fromgroups#!searchin/web2py/app.example.yaml/web2py/cd8Smoiv1V0/x-INRnFgJNoJ.
 
The book should be changed to reflect this.
 
Anthony

Re: [web2py] Re: OpenERP like widgets

[Indra Gunawan]

1. What stuff I need to build like that* web interface?
2. Is there ready to use Python classes that wrap for example ExtJS classes,
or the other?
3. Can you points me in general; steps building like that* website using
Web2Py?

For example.
1. You need this, this and this
2. Do like this in your controller and put like this in your template
3. Done, you get responsive ajax based web interface like that*

PS. Sorry my English :)

Thank you

Re: [web2py] Re: onmouseover

[Kenneth Lundström]

I got the onmouseover to work but how do I send text to the javascript 
from a variable. I have this code


 TD(P(day, _class="text_black"), _class="red", 
_onmouseover="displayText('info', watchers[check_date])", 
_onmouseout="hideText('info')")


It is the watchers[check_date] that holds the text that should be sent 
to the javascript but nothing is sent.


I have verified that the variable contains text and if I define 
_onmouseover="displayText('info', 'test_text')",


it works.


Kenneth


Yes. The error is probably in other order

TD(_onmouseover="","content") WRONG
TD("content",_onmouseover="") RIGHT
