[web2py] Re: py4web - form field default - appears to not be working for me

[Massimo Di Pierro]

can you try this?

form = Form()
if not form.submitted: form.vars.update({field.name:field.default for field 
in form.table if field.default})

Maybe I can make this default behavior?

Re: [web2py] py4web - using session object in a template

[Massimo Di Pierro]

Lazy is good. You can turn it to your advantage with this:

import functools
def my_awesome_decorator(path=None, method=['GET','POST'], 
requires_login=False):
def wrapper(func, path=path, method=method, 
requires_login=requires_login):
path = path or func.__name__
template = func.__name__+'.html'
fixtures = [template, db, session, auth]
if requires_login: fixtures.append(auth.user)
@action(path, method=method)
@action.uses(*fixtures)
@functools.wraps(func)
def tmp(*a, **b):
d = func(*a, **b)
if isinstance(d, dict):
 d['session'] = dict(session.local.data)
 if requires_login: d['user'] = auth.get_user()
return d
return tmp
return wrapper

@my_awesome_decorator('test')
def index():
return {}

 Hi

 I'm trying to pass a session variable to layout.html but it tells me 
 that session is not available:

 NameError: name 'session' is not defined

 I use this technique in web2py to send a page title to layout.html 
 without having to pass it in the returned dict from the controller.

 Obviously I'm being lazy using this technique.  Will this work with 
 py4web or is it best for me to pass in explicitly in each controller?

[web2py] Re: Is there a working bootstrap3 formstyle for auth?

[Alexander Hoch]

Thx, that solved my problem after I reloaded my old web2py app.
When generating SQLFORM an error "Formstyle not supported occurs".
I added 
[forms]
formstyle = bootstrap4_inline
separator =
 to appconfig.ini 
and it works.

[web2py] py4web - form field default - appears to not be working for me

[Jim S]

Sorry for all the py4web noob questions

I have the following:

search_text = 'test'
form = Form([Field('search',
   length=50,
   default=search_text)],
form_name='search_form',
formstyle=FormStyleBulma,
keep_values=True)

I can't get the default search_text to appear in the field.  

Anything obvious I'm missing?

[web2py] Varying membership

[Aydin]

I have a bunch of accounts in web2py and I want to create for each a group 
that additional users could access those accounts. For example, account 1 
has a group id 1 and now I want to add additional users to this group. The 
problem I have is how can I use this group id to authorize. Meaning that 
when I use @auth.requires_membership(group_id = i) for the same function, i 
is something that varies. Maybe there is a much better way you can suggest 
for this need?

[web2py] py4web - name of form - add classes to form

[Jim S]

I'm using Form from:

from py4web.utils.form import Form

I want to add some classes to the  tag that is generated.  In web2py 
I can add _class='field is-horizontal' when creating the instance and the 
classes will be passed along.

Optionally I could add some css/javascript that could modify the classes.  
However, then I need to be able to reference the form.  I assumed I could 
do that with the form_name argument, but that doesn't add a name or id to 
the form element.  It is used on some of the children, but not on the form 
itself.

How can I add classes to the form and to the elements inside the form?

Thank you, that did the trick.

Now however, I'm getting this traceback:

[web2py] py4web - method not allowed

[Jim S]

I'm getting the following when I click on the submit button on my form:

Error: 405 Method Not Allowed

Sorry, the requested URL 
'http://127.0.0.1:8000/py4web_test/administration/links' caused an error:

Method not allowed.

My controller code:

@action('administration/links', methods=['GET', 'POST'])
@action.uses('grid.html', session, db, auth.user)
def links():
url_path = 'administration/links'
page['sub_title'] = A('LINKS', _href=URL(url_path))

form = Form([Field('search', length=50)], formstyle=FormStyleBulma)

query = db.link.id > 0
fields = [db.link.id, db.link.name, db.link.table_name, db.link.
permission_name, db.link.method]

grid = Grid(url_path, query, fields=fields,
search_form=form,
create_url=URL('administration/link/0'),
edit_url=URL('administration/link'),
delete_url=URL('administration/link/delete'))

return dict(page=page, grid=grid, form=form)

I'm guessing there is something obvious I'm missing.  Can anyone see it?  
Any help would be appreciated.

Re: [web2py] py4web - using session object in a template

[Jim Steil]

Thanks Massimo.  I was hoping to avoid having to pass something to the view
every time.  I'm lazy, right?  I'm assuming that this is the same if I used
response instead of session.  In web2py you didn't have to pass response to
the view, it was automatically available.

[web2py] Re: Displaying for loop results only once

[Tim Nyborg]

Simplest fix: use "any" instead:

{{for bookings in bookings:}}

  {{if any(bookings.company in q.customer.company for q in quotes):}}
Quoted
  {{pass}}

{{pass}}


To avoid all this looping, you could have a separate query join the two 
tables and count the matches.

[web2py] Re: running two web2py instances on the same server under apache wsgi mod

[Tim Nyborg]

Yes, that should work.

I have three web2py instances on a server running nginx/uwsgi, and the 
principle's the same: slightly different configs for each instance, 
pointing to separate source files.

[web2py] running two web2py instances on the same server under apache wsgi mod

[Manuele Pesenti]

Hi!

If I need to manage on the same server two different web2py instances 
(for example for having two distinct versions of web2py running) what 
are the differences I have to consider with what reported in 
documentation[1]?


At the moment I already have the first instance running through wsgi mod 
using this configuration




  ServerAdmin d...@colouree.com
  ServerName apps.mycompany.com

  RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]

  CustomLog /var/log/apache2/access-apps.log common
  ErrorLog /var/log/apache2/apps.error.log




  ServerAdmin d...@colouree.com
  ServerName apps.mycompany.com

  SSLEngine on

  WSGIDaemonProcess web2py python-home=/path/to/pyenv27 user=myuser 
group=mygroup processes=1 threads=1

  WSGIProcessGroup web2py
  WSGIScriptAlias / /path/to/web2py/wsgihandler.py
  WSGIPassAuthorization On

  
    AllowOverride None
    Require all denied
    
  Require all granted
    
  

  AliasMatch ^/([^/]+)/static/(?:_[\d]+.[\d]+.[\d]+/)?(.*) 
/path/to/web2py/applications/$1/static/$2


  
    Options -Indexes
    ExpiresActive On
    ExpiresDefault "access plus 1 hour"
    Require all granted
  

  Include /etc/letsencrypt/options-ssl-apache.conf

  CustomLog /var/log/apache2/ssl-apps-access.log common
  ErrorLog /var/log/apache2/apps-error.log
  ServerAlias applications.colouree.com
  SSLCertificateFile /etc/letsencrypt/live/apps.mycompany.com/fullchain.pem
  SSLCertificateKeyFile 
/etc/letsencrypt/live/apps.mycompany.com/privkey.pem



can I simply duplicate it changing essentials informations such 
WSGIDaemonProcess definition (I'd like to specify even the path to a 
different virtualenv based on python 3 in the second case) and other stuff?


Thank you very much

Best regards

When posting a new euqestion, please don't check "show at the top" --- save 
that for messages that need to be displayed long-term,
like etiquette or policy.

Have you looked at README.md at
https://github.com/web2py/py4web> ?

This should make a small stand-alone server and one or more sample 
applications.

If you have looked at that introduction, what questions do you still have?

Also, look at the py4web documentation at


I haven't heard of any training videos yet (the older framework, web2py, 
has several, but those wouldn't be useful for py4web).

If you need to learn more about setting up a front-end server, such as 
NginX, you should consult the NginX website.  
(the web2py position on Apache is that if you don't have it already, you 
should consider NginX or other easier-to-use front ends.)

Good luck!

The first idea I have is just to return the latest entries from the log 
file.  

If your control application is polling the controllers, you can set up 
something else for it to poll, and put something there with the web app, 
and issue a response to it.

If you control application is being pinged by the controllers, perhaps you 
can use a socket to ping it from the web app.

Much beyond that handwaving response would require knowing more about the 
existing architecture.

For what it's worth, that is where web2py expects it on my AWS system; my 
issue was using the proper version of pip to install it.  Full descriptions 
of my fun in the archives.  (I'm still on 2.15.4, while I keep saying 
"2.18.x any day now")
