[web2py] Re: Implementing tornado chat server with web2py

[Red Arrow]

for chatting, usually use XMPP like Gtalk or facebook chat. If
choosing between gevent or tornado, gevent can handle better than
tornado.

Maybe something like:

auth.settings.register_onaccept = lambda form: 
mail.send(to=['ad...@yoursite.com'],
subject='Registration pending',
message='New user (id = %s) waiting for approval' % form.vars.id)

Note, that will introduce a slight delay for the user because it may take a 
second or two to send the email. An alternative is to queue the email for a 
background 
task:

[web2py] Re: Packaging web2py + application

[LightDot]

Is Python 2.7 a must? There are python 2.6 RPMs available from EPEL 
repository. They install parallel to the existing python 2.4 and thus 
avoids breaking yum and other applications that rely on stock python 2.4.

Python 2.7 could be packaged in a similar way, but by using this existing 
packages from EPEL (Fedora project), you'd avoid maintaining a custom set 
of python RPMs.

Packaging web2py and your application shouldn't be a problem. Making web2py 
RPMs is very straightforward and I've been doing it for a while for an 
internal web2py project of ours.

If you decide to go this route yourself, I'd recommend reading Fedora's 
packaging how-to's, as they seem to be quite complete and applicable to 
CentOS/SL/RHEL with very minor modifications. Than just have a look at some 
simpler existing .spec files and go from there, it's not as hard as it 
might look.

Re: [web2py] Re: global functions in models

[Tsvi Mostovicz]

I managed to find the culprit. The function before it had a mismatched
parentheses. So it would continue reading this function and fail on
compilation. Thanks for all your replies.  The append works, although
if this is a new user and no list has been defined yet it won't. So I
check if it returns None, set the list to [] and then have the append
statement.
I thought all the vars would be initialized by default so a list type
would return [] if it wasn't set in the form.

Another thing I learned is the fact that the function must receive one
argument (form).

Thanks again for the wonderful support.

What you say is true, however for argument's sake, how could I achieve

In my situation, the 3 tables have different fields (but I didn't have

[web2py] Re: default_application showing full url

That's probably because default_controller defaults to 'default', and 
default_function defaults to 'index' -- you might get the full URL if you 
explicitly set those to None in your router (haven't tried it).

[web2py] default_application showing full url

[Leopold]

Hi all,

I have an application "myapp" which I want to make it the default app
when I navigate to the base domain (let's say "localhost" for now). By
adding:
default_application = 'myapp',
to the routers BASE dict in routes.py I am able to do that, however it
shortens the resulting url from "localhost/myapp/default/index" to
just "localhost".

I read that if I still want the complete url to be displayed by the
browser I should add:
applications = None,
to the same dict, however it doesn't work, it still shows the short
form of the url (displaying myapp as it should).

Here's the dict I added in routes.py:

routers = dict(

# base router
BASE = dict(
default_application = 'calidad',
applications = None,
),
)

I hit Reload routes and even close and start web2py again but still
the application name gets removed.
Any help?
Thanks.

Right, sorry. You could simply move it to right after all the auth tables

[web2py] Re: crud update with writeable=readable=False

[Anthony]

The readable and writeable attributes of a field can be set conditionally 
(e.g., depending on request parameters or user authorization) or changed at 
any point in your code, so you could do:

db.define_table('auth_user', ...,
Field('approved', writeable = auth.has_membership('admin') and True or 
False))

Or in the action that generates the form to be used by the admin user:

db.auth_user.approved.writeable = True
form = SQLFORM(db.auth_user, ...)

[web2py] Re: crud update with writeable=readable=False

[Alan Etkin]

One way is to configure this attribute in the custom form action:

db.auth_user..readable = True

Other actions will use the readable and writable values defined at the
model.

StaticPython looks pretty cool, but there are two issues I see with this:

First, my target platform is 64-bit. StaticPython is only 32-bit.
Second, the RPM is a requirement. In the future, we may create a yum repo 
for the application for updates and things like that, so we have to use RPM 
from the beginning.

[web2py] Is there an example? RPC between applications

[Bruce Wade]

"The XMLRPC client can also be implemented inside a web2py action, so that
one action can talk to another web2py application (even within the same
installation) using XMLRPC." Is there an example of how to properly do this?

The situation is:
1) We have multiple applications in the same installation which share a
single database and also have their own database for their unique
application. The shared database I would like to create an application that
provides RPC access to handle all the data related operations.
2) We are developing an android based application that will also need to
access the shared database via RPC. This means we need the ability to
handle logging into the system so the RPC knows which data to return based
on the logged in user.

Current I have an api application that has all the models created for the
database now I am working on creating the RPC api.

Re: [web2py] Packaging web2py + application

[Angelo Compagnucci]

I can suggest you http://code.google.com/p/pts-mini-gpl/wiki/StaticPython

It's a statically compiled version (and runtime) of python, you can drop it
in web2py folder and write a script that starts

./python web2py.py 

In this way you have not to fight with rpm packing (I made several packeges
for opensuse ...), you can yust zip your application. This bynary works
well on all linux x86 x86-68 archs and it's not influenced by the
distribution you are running.

[web2py] How to do that: Verifying email account ownership

[thstart]

Verifying email account ownership - I am brainstorming for the best way to 
know email address is owned by an user.

Something like that - a user enters email address, my app
generates a code and sends an email message with a link with this
code, the user clicks and comes to my app which thus verifies he 
is the owner of the email account.

Similar to reset password. 

How is the easiest wat to do that with web2py?

I have tables with individual properties,

db.define_table('article',
  Field('title', 'string', length=255,required=True),
  Field('description', 'text',required=True),
)
db.define_table('post',
  Field('title', 'string', length=255,required=True),
  Field('description', 'text',required=True),
)
db.define_table('page',
  Field('title', 'string', length=255,required=True),
  Field('description', 'text',required=True),
)

And I have a table with many-to-many relationship (with different
tables):

db.define_table('action',
  Field('user_id','reference
auth_user',default=auth.user_id,required=True),
 
Field('action','string',requires=IS_IN_SET(('fav','subscribe','report','follow')),required=True),
  Field('table',requires=???,required=True),
  Field('table_id','integer',default=???,required=True),
)

My questions:
1.. The field, "table" is actually one of the tables, article/post/
page. Is the only correct way to use
requires=IS_IN_SET(('article','post','page')) ?

2.. "table_id" is actually dependent on the "table" selected. what
should I put for "default=???"

3.. Can I set a different set of IS_IN_SET for "action" field,
depending on the "table" field chosen?

4.. Finally, if the above is the wrong approach, how should I do it
correctly (best practice?)

Thanks!

The globals being accessed in the above linked example (which is actually 
the 'welcome' app layout.html) are defined either in models or in another 
(included) view, not in a controller.

It depends. An extended view sees variables defined in an extending view if 
(a) the variables are defined in the extending view before the {{extend}} 
directive, or (b) the variables are referenced in the extended view after 
the point where the extending view has been included. The sidebar example 
in 'welcome' linked above works via (a). Note that /default/index.html in 
'welcome' starts with:

{{left_sidebar_enabled,right_sidebar_enabled=False,True}}
{{extend 'layout.html'}}

By defining left_sidebar_enabled and right_sidebar_enabled before extending 
layout.html, those variables are defined before any of the layout.html code 
is executed, so they are available anywhere in layout.html (including 
within any other views included within layout.html). When executing a view, 
web2py first pieces together the entire page, with all extends and 
includes, and then it executes the Python code to generate the HTML.

In your second example, you have:

response.render('default/test.html', globals()) 

Passing globals() to response.render() adds all the globals to the 
environment in which the view is rendered (actually, most of the objects in 
globals() are already in the view environment, so you are only really 
adding any new globals created in the controller). Your first example would 
be equivalent to:

response.render('default/test.html', dict()) 

which is simply equivalent to:

response.render('default/test.html') 

In that case, the view environment includes all the globals defined in the 
models (as well as the web2py framework globals), but you haven't added any 
variables generated in the controller to the view environment.

[web2py] Re: How do Global Variables Work?

[Massimo Di Pierro]

The list of global variables defined in models and passed to the
controllers are also passed to the view (for example the views see db,
request, session, etc. globals variables defined in controllers are
not passes to the view unless done explicitely.

[web2py] Re: How do Global Variables Work?

[Peter O]

http://web2py.com/books/default/chapter/29/5?search=globals%28%29

I see. Am I right that View doesn't see the global variables (in 
Controller), but the parent View sees the variables in View as global 
variables?

Then, what causes the difference between Example 1 and 2? What's the 
relationship between the 'environment' and the 'context' in response? How 
do I access the 'environment' explicitly in the Controller?

Which example? 

[web2py] Re: How do Global Variables Work?

[Anthony]

See http://web2py.com/books/default/chapter/29/4#Workflow:

"The view sees every variable defined in the models as well as those in the 
dictionary returned by the action, but does not see global variables 
defined in the controller."

web2py builds an environment and runs the models in that environment (which 
may then add objects to it). It then creates a copy of the environment 
before running the controller, and after running the controller, it adds 
the items returned in the dictionary by the controller to the 
pre-controller copy of the environment, which is where the view is 
executed. You can see this 
here: http://code.google.com/p/web2py/source/browse/gluon/main.py#200

Re: [web2py] How do Global Variables Work?

[Peter O]

I understand explicitly passing the variable will do the work.

However, what's the purpose of global variables? I thought this conflicts 
with one of the examples in the Introduction chapter.

Secondly, I don't understand the different results between Example 1 and 2. 
Something deeper is happening here, I feel.

you need to pass it

return dict(t1=t1)

[web2py] How do Global Variables Work?

[Peter O]

Hihi,

I am baffled by what I see between Example 1 and 2.

It may be a good case to improve my understanding of the run-time 
environment of web2py.

Thanks in advance for any comments.

VIEW: (test.html)

  
{{=globals().get('t1', False)}}
  

CONTROLLER:

== Example 1 ==

def test():
global t1
t1 = True
return dict() # the browser show 'False'. I was expecting 'True'

== Example 2 ==

def test():
global t1
t1 = True

response.render('default/test.html', globals() ) #the return is 
discarded

return dict() # the browser show 'True'. I was expecting the same 
result as Example 1.

[web2py] Movuca - The Social CMS - Need Testers and Contributors

[Bruno Rocha]

Hi,

I am developing a Social CMS, I was very inspired by vikuit.com but I made
some conceptual improvements on what I think is a Social CMS.

This is a simple system based in Articles, Content Types, Themes, Users,
Activities etc...

The code is in github[1] and you have to note that I am trying a different
approach which is very un-web2pythonic and it is already under tests.

The demo page is alive[2] Please help me test it! register, login, create
articles, like, dislike, favorite, comment etc...

If you have suggestions or ideas please let me know!

I need opinions, testers and contributors.
