[web2py] Re: Reverse Proxy problem with grid form (bootstrap 3.x)

[Daniel Vogel]

Hi,

Some additional information. With older web2py versions (bootstrap 2.x) we 
have wrong sizing with the login behind reverse proxy (field has not the 
normal size).
With the new web2py version the problem is gone, but a new one appeared 
(see my first screen shot). I think it's a bug.



(Login field behind reverse proxy, bootstrap 2.x)

Thanks

[web2py] Eclipse + Pydev + Docker - need suggestions

[Kiran Subbaraman]

Hello,
I need some help with understanding the best way to use Pydev with Eclipse, 
for web2py applications development. 
I have been working with web2py for the past year, and use the tools 
mentioned above for this purpose. Am trying to refine my understanding of 
this toolset, and if there is something more that can be done to improve 
the experience.

I use Eclipse IDE (Luna Service Release 2 - 4.4.2), with Pydev 
(4.3.0.201508182223), on Windows (10.0.10240), as my web2py development 
environment.

*Sorting out web2py imports*
I was looking at the documentation: 
http://web2py.com/books/default/chapter/29/14/other-recipes#Using-general-purpose-IDEs-with-web2py.
 
Went ahead and added the code to resolve imports:

if False:
from gluon import *
request = current.request
response = current.response
session = current.session
cache = current.cache
T = current.T


...It is probably wise to remove the import of the gluon debug module. 
> Also, to do this you should make the pydev project the web2py directory, 
> not your specific application.
>
> PyDev's git integration copes with this; it supports multiple git 
> repositories inside the one project directory structure.
>

I didn't quite understand what this means? It seems to suggest a means to 
debug applications from within Eclipse; can anyone elaborate on how to get 
this done. I can test it out, and contribute to improving the 
documentation. 


*Applications outside of web2py*
I also noticed this response from Massimo: 

Actually the web2py applications/ folder is not required to be under the 
> the web2py folder..


https://groups.google.com/d/msg/web2py/wi25qItKDEo/w-RbzvykRfcJ
So, I need to create a *web2py/options.py*, which has the property
folders = /web2py_applications #docker volume, for example

This will help me create web2py docker-containers, which point to my 
applications code outside of the containers. The applications themselves 
are in a git repository. Is this a setup that anyone has tried out before. 
I noticed this thread by Massimo, but that was inconclusive: 
https://groups.google.com/forum/#!searchin/web2py/docker/web2py/XhrfaYX00dg/6koPFbJWfNYJ
Any suggestions?

Thanks,
Kiran

[web2py] Re: Multi file upload

[Luis Valladares]

Hello! turns out that i've not handled it well from the server, so in 
changed my approach to this and worked flawlessly:

In the view:

 
  {{=T('Archivo')}} 
#1   
  {{=T('Descripción')}} 
#1Añadir otra foto  


The "añadir otra foto" button adds another field, with the formar foto_X 
descripcion_x where X is a consecutive number.

Later in the controller i do this:

 if var.startswith('foto_') and request.vars[var] != '':
uploaded = request.vars[var]descName = var.replace('foto', 
'descripcion')descripcion = request.vars[descName]  
  db.hoteles_fotos.insert(fk_hotel_id=id, 
descripcion=descripcion,
ruta=db.hoteles_fotos.ruta.store(uploaded.file, uploaded.filename))

[web2py] Re: Questions about authentication and authorization

[Luis Valladares]

After some discussion with my team we come with this architecture:

We will have a service to manage authentication and authorization, all our 
services will query him in order to get permission and credential, for 
authentication we will use CAS and for authorization RBAC over sended over 
JSON.

I've another question, exactly how CAS works? i mean, i know the theory 
that you log in the CAS provider and you will be logged in the CAS 
consumer, but how this works? with session cookies and a token? or how CAS 
communicate with the consumers

[web2py] Polymer and SQLFORM

[Luis Valladares]

Hello!

I'm building a web2py site and i want to use polymer as my front-end 
"framework", as you may know polymer uses web elements with custom html 
tags, i mean, a input is something can be something like



I want to integrate this "feature" with the web2py SQLFORM module, after a 
bit of research i came with this approach, im not sure if its correct so i 
accept suggestion:

i've to override all the FormWidget class inside sqlhtml.py and modify all 
widget to generate a HTML output adapted to my custom tags, also create a 
custom formstyle related to polymer and maybe (and this is one of the 
problems i've found) create some sort of custom HTML helper for generating 
the HTML custom tags.

I think i miss a lot of changes needed for this to work well, so i am 
looking for opinions in this matter, i'm correct in my planning, or maybe 
there is a easier path to join SQLFORM and Polymer, or may be better to 
work without SQLFORM?

Thank for any help you can provide

[web2py] Re: Not Authorized exposing folders

[Anthony]

You're providing a relative file path. Instead, try:

import os
Expose(os.path.join(request.folder, 'albums'))

If the path is in a different application, you could do:

Expose(os.path.normpath(os.path.join(request.folder, '..', 'other_app', 
'albums')))

[web2py] Re: what can I do with this error: Getaadrinfo Failed.

[Massimo Di Pierro]

Please submit a bug report. Do you have any more detail about the error and 
the OS you are using to build and to run the exe code?

I am not sure I filly understand. There is not mail.settings.to. "to" is a 
mandatory argument of mail.send().

Re: [web2py] Re: Autocomplete widget don't respect other values in request.vars

[Yoel Benitez Fonseca]

As Anthony suggested in the workarounds:

--

city_widget = SQLFORM.widgets.autocomplete(request, db.city.name,
id_field=db.city.id)
city_widget.url = URL(args=request.args, vars=request.get_vars)
db.person.city.widget = city_widget
--

turn to another problem, this is the content of request.vars for the
callback from autocomplete:



It should be:



As you can see, autocomplete just add his parameters to the url
assuming there are no other.

Re: [web2py] Re: Autocomplete widget don't respect other values in request.vars

[Yoel Benitez Fonseca]

Thank's Antony for the replay, i'll create the issue.

The error in the code come from my adaptation of the real code to the
example posted in my original question.

The reason I ask is because I have already taken account of these
three possible workarounds and i think we can do better.

[web2py] 3 field validator

[Annet]

I've got the following table definition.

def set_requirement(edg_edge): db.edg_edge.label.requires=[IS_IN_DB(db_st, 
'st_edge_label.name', '%(name)s', zero=T("Select a value")), 
IS_NOT_IN_DB(db((db.edg_edge.fromID==request.vars.fromID) & 
(db.edg_edge.toID==request.vars.toID)), db.edg_edge.label, 
error_message='Realtie al in database')]

db.define_table('edg_edge',
Field('fromID', 'reference vtx_vertex', default='', 
requires=[IS_IN_DB(db, 'vtx_vertex.id', '%(name)s', zero=T("Select a 
value"))], notnull=True),
Field('toID', 'reference vtx_vertex', default='', 
requires=[IS_IN_DB(db, 'vtx_vertex.id', '%(name)s', zero=T("Select a 
value"))], notnull=True'),
Field('label', length=128, default='', notnull=True, 
widget=SQLFORM.widgets.options.widget),
on_define = set_requirement,
migrate = False)

To prevent the user form entering the same edge twice I defined the 3 field 
validator. However it does not
work and I do not see what's wrong with my code.

The user can enter:

fromIDtoIDlabel

2 3 sponsor
2 3 sponsor

which the validator should prevent.


Kind regards,

Annet
