good catch! we will have to refactor that to support earlier versions of 
python.

 It contains some bug fixes for bugs introduced in 2.13.1-2 and most 
 importantly it contains experimental support for JWT. Here is how it works:

 1) instantiate auth with

 auth = Auth(db, jwt = {'secret_key':'secret'})

 where 'secret' is your own secret string. 

 2) Secorate functions that require login but should accept the 
 JWT token credentials:

 @auth.allows_jwt()
 @auth.requires_login()
 def myapi(): return 'hello %s' % auth.user.email
 
 Notice jwt is allowed but not required. if user is logged in, 
 myapi is accessible.

 3) Use it!
 Now API users can obtain a token with

 http://.../app/default/user/jwt?username=...&password=

 (returns json object with a token attribute)
 API users can refresh an existing token with

 http://.../app/default/user/jwt?token=...

 they can authenticate themselves when calling http:/.../myapi 
 by injecting a header

 Authorization: Bearer 

 Any additional attributes in the jwt argument of Auth() below:

auth = Auth(db, jwt = {...})

 are passed to the constructor of class AuthJWT. Look there for 
 documentation.

 Thanks Niphlod again for implementing this. 
 Please help us check it so we will declare it stable in the next 
 release.

 Massimo

[web2py] Re: web2py 2.13.3 is OUT

[Lou C]

I am running version 2.13.4 on GAE which runs on python 2.7.5. The problem 
arises when using the @auth.allows_jwt() decorator. The error I get is 
AttributeError: 
'module' object has no attribute 'compare_digest'.  
Which is being called in :

def verify_signature(self, body, signature, secret):
mauth = hmac.new(key=secret, msg=body, digestmod=self.digestmod)
return hmac.compare_digest(self.jwt_b64e(mauth.digest()), signature)

I believe this is because hmac.py uses compare_digest in version 2.7.7. 
Anyway to use jwt on GAE ?

[web2py] Re: How to edit the menu bar so as to remove profile and name in front of welcome in the dropdown?

[Massimo Di Pierro]

Edit views/layout.html and remove {{=auth.navbar()}} which is 
responsible for drawing that part of the page. Then write your own code for 
it

{{if auth.user:}}
logout
{{else:}}
login
register
{{pass}}

add html as needed depending on how you want it to look.

[web2py] Re: Have a more complex organize of controller files

[Anthony]

No, you cannot organize controller files into subfolders. However, you can 
make controller functions that are simply routers to functions that you 
organize in modules (you can use URL args to determine the routing).

Trying to display rows using the datatables.net DataTable() function by 
converting query results to JSON, but getting error "Uncaught SyntaxError: 
Unexpected token &". Though the raw data displays correctly in the view 
below, when I look at the results in the web console debugger I see that 
the generated program seems to show the JSON converted back to XML:


$(document).ready(function(){
$("#person-table").DataTable({
"aaData":  [{"first_name": "Super", 
"last_name": "Man", "id": 1}, 
{"first_name": "Massimo", "last_name": 
"Di Pierro", "id": 2}]) 
 
})
});

in model db.py:
db.define_table('person',Field('last_name'), Field('first_name'))
db.person.update_or_insert(last_name='Man',first_name='Super')
db.person.update_or_insert(last_name='Di Pierro',first_name='Massimo')

in controller default.py:
def index():
import json
people = json.dumps(db(db.person).select().as_list())
return dict(results=people)

In view index.html:
   


ID
First name
Last name



 ...
Raw data

 results: {{=results}}



$(document).ready(function(){
$("#person-table").DataTable({
"aaData":  $.parseJSON({{=results}})   
   
})
});


The view prints out an empty Datatable, followed by correctly formed JSON 
in the "Raw Data" portion:

  ID First name Last name

  Raw data
  results: [{"first_name": "Super", "last_name": "Man", "id": 1}, 
{"first_name": "Massimo", "last_name": "Di Pierro", "id": 2}]

[web2py] Have a more complex organize of controller files

[Alessio Varalta]

Hi, I have a problem with my logicI want to know if is possibile to 
have in the controller this structure

folder(main)/with the file py and this case how the url work

Because for example i have the enttity Coperative and i have different page 
that work with this entity ..so I want to have a folder 

Coperative-and inside this the controllers..For me this is a good logic. 
Now in this moment i have one page controller Coperative with 7 or 8 
functions that use module and class. But i note that is not so good to have 
many controllers, create many file that are not in a folder that divide the 
files is not so good. So is possibile this operatiion?

folder Coperative/controller.py ??Works?

Thanks in advance?

Re: [web2py] Re: Why am I getting validation error in RESIZE here? I have installed PIL and uploaded images.py module

Your second screenshot clearly shows you are running web2py.exe (the 
windows binary) and not the web2py.py (the source version). As I said, you 
have to run web2py from source. The windows binary comes with its own 
version of Python and it does not include PIL.

[web2py] Re: Why am I getting validation error in RESIZE here? I have installed PIL and uploaded images.py module

[Massimo Di Pierro]

RESIZE requires PIL installed. The windows binary version of web2py does 
not come with PIL. You have to install python 2.7. Then install PIL. Then 
run web2py from source.

[web2py] Re: Web2py con UDOO

[Vinny Mautone]

Si il mio scopo è quello di far leggere a python ad intervalli regolari i 
vari sensori e farlo andare a scrivere sul db, poi quando apro l'app web2py 
ho la possibiltà di visualizzare i dati scritti sul db, ma mi occorre anche 
che dall'app posso andare a scrivere anche su arduino, nel senso che vorrei 
creare delle slidebar per aumentare o diminuire la luminosità o 
l'impostazione della temperatura quindi utilizzando queste slidebar 
sull'interfaccia web comando arduino.

Grazie

[web2py] Re: Web2py con UDOO

[Massimo Di Pierro]

My assumption is that you want to read your sensors at periodic time 
intervals, whether or not you are looking at them from the web interface. 
You can do this with the web2py scheduler but I think it is overkill. I 
would just create a process that loops and records he sensors in your 
database (or perhaps a CSV file). Then your web app just reads the data 
displays it to the user and makes plots.

[web2py] Web2py con UDOO

[Vinny Mautone]

Ciao a tutti sto cercando di creare qualcosa per le automatizzazioni del 
mio acquario ho acquistato una UDOO quad e sto iniziando a testare arduino, 
ma il mio scopo è quello di creare un'interfaccia web dalla quale leggere i 
vari dati messi a disposizione delle sonde che collegherò ad arduino e in 
più eseguire operazioni diciamo manuali, "cambio livello di illuminazione, 
fermare la pompa del filtro, ecc." ovviamente tutte queste saranno fatte da 
arduino. Le varie sonde andranno a scrivere su un database mysql.
La mia domanda è questa, potendo comandare arduino con Python tramite la 
libreria Pyserial posso creare un'app completa con web2py che legga e 
scriva da seriale su arduino, oppure devo creare un programma a parte che 
faccia tutto il lavoro per arduino e con web2py creare un app che legga dal 
database e mi visualizzi i valori?

Grazie

[web2py] why you should upgrade to web2py 2.13.4

[Massimo Di Pierro]

There are many reasons you should upgrade, depending on which version you 
are using now:

- to help us make sure we did not break backward compatibility. If your 
existing app does not work with 2.13.4 (and it should) you give us a chance 
to fix the problem. If no, any potential incompatibility will propagate 
forward making it more difficult for us to fix it later, and more difficult 
for you to upgrade.

- to take advantage of new features. For example the awesome JWT feature 
that allows to create API tokens and use them for authentication without 
hitting the database.

- there is also an important security bug fix in 2.13.4 related to 
auth.settings.registration_requires_approval=True. The bug allows a newly 
registered user to bypass the approval process and approve himself/herself. 
Under come conditions. This is now fixed.
