Massimo, Thanks for your reply now  I am working with new version 1.96.4 but
now as given in cas_auth.py

I have update my db.py with

from gluon.contrib.login_methods.cas_auth import CasAuth
auth.define_tables(username=True)
auth.settings.login_form=CasAuth(
urlbase = "http://127.0.0.1:8000/casapp2/default/user/cas

still geting error:

[web2py] Re: The multi-tenant feature and validators ...

[rif]

I used this feature like this:

db._common_fields.append(Field('request_tenant',default=auth.user_id,writable=False,readable=False))

so every user would have it's own data.

It seeams that IS_IN_DB is not aware of the request_tenant and also if you 
mark a filed as unique it will be unique across accounts. So it will say 
some data is not unique even if I have not entered it before but someone 
else did. 

[web2py] Re: web2py and async monkey patching

[graeme]

Thanks for the reply.

So what anyserver.py does with gevent is not recommended? It calls
monkey.patch_all() which patches threading to use green threads.

Is this something that ought to work but is just untested? web2py is
pure python so the monkey patching should make thread locals into
greenlet locals, right? If that is so, then is the testing something I
could do myself, or does it need to be done by someone who knows the
internals of web2py?

[web2py] Legacy database adaptation in web2py, best way?

[DanielB]

So we have a legacy database that has a suboptimal structure, but we
cannot change it right now.
What we want is to create a business layer in-between web2py and this
database so that web2py thinks it is using a much better database
structure in order for the development in web2py to be what we want
the end result to be when the database is finally restructured.

By defining a sort of virtual model in web2py (that is more how we
want the final database to look like) we can use the benefit of
creating forms very easily in web2py, and then just forward the
results to the business layer and let it take care of the real
database.

But problems arise when the web2py forms etc. assumes that the model
really has a physical database behind it, for instance the CRUD forms
where the crud.update gathers info on the record from database and
puts it in the form automatically. We want this of course but the
web2py model has no real database.

One way of doing this would be to use SQLFORM.factory and manually
inserting all the values into the inputs like so:
inputs = form.elements('input')
inputs[0]['_value'] = user.name
inputs[1]['_value'] = user.email
...
but this sort of manual work seems unnecessary for big forms

Another problem I had with CRUD forms in my case is that I really want
to make the if .accepts() call myself so that I can then call the
business layer with the database related stuff, but it seems the CRUD
forms do this call automatically?
In the case of SQLFORM.factory forms I can make the .accepts myself

Do any of you have experience in these kinds of problems? Is there a
painless way to do it?
I would be most thankful for any tips regarding this

[web2py] Running web2py on Jython

[Richard]

Hi,

has anyone running a reasonably current version of web2py running on
Jython 2.5.x? I need help with this.

>From reading the available information on the web I gained the
impression that Jython 2.5 is a fully supported platform. Wikipedia
says "web2py since v1.64.0 runs unmodified on Java with Jython 2.5,
without any known limitation". The Official (3rd Ed.) web2py Book
seems to support this claim, although the installation instructions
seem to be a bit outdated (zxJDBC is included in the 2.5.x Jython
install Jar, no need to install it separately).

The problem is, my experiences so far are very different. Here is the
reason why I am asking for help. I am facing a situation where I want
to have web2py running on a Linux host on which  I have no admin
rights. The problem is that this machine has only Python 2.4
installed. Although web2py claims to be running on Python 2.4, it
really doesn't out of the box. A backported hashlib module would have
to be additionally installed. This doesn't seem to be a viable option
for me, given my limited admin rights on this machine. A Jython
install on the other hand should pose no problem. The additional gain
of this approach is, Jython 2.5 is an officially supported Python
version (2.5.2), Python 2.4 is not.

I can only try this next week for real, but I did some preliminary
tests on my local machine during the last few days. I tried on Windows
XP with Jython 2.5.0/ 2.5.1/ 2.5.2. I tested on an old (but updated)
Ubuntu installation with Jython 2.5.2. I tested on a Linux VM running
on Virtualbox 4.0.8. The consistent result for me was that the current
web2py releases don't work on Jython. For example with R-1.90.2 and
later the welcome app shows immediately (on first access) a ticket.
Root cause has something to do with the sqlite driver
('com.ziclix.python.sql.PyConnection' object has no attribute
'create_function'). Even older versions seem to raise exceptions with
tracebacks shown in the Jython console, hinting to 'rocket' and
'multithreading'. Details available upon request.

The most 'recent' version of web2py that seems to be running with
Jython 2.5.x seems to be 1.85.2 (hg commit #907). Even #918 seems to
be working fine. Later versions don't. I diffed the sources, but
somehow couldn't make sense of it.

So that is where I am standing now. What I am doing wrong? I seem to
be quite alone with my experiences since Google didn't provide
pointers to fellow sufferers. To reiterate my question: Has anyone
running a reasonably current version of web2py running on Jython
2.5.x?

Regards,
Richard

[web2py] Re: web2py and async monkey patching

[Massimo Di Pierro]

The test is easy:

def index():
import time
from gluon import current
print current.request.uuid
sleep(10)
print current.request.uuid
return 'done!'

call this action twice from console within less then 10 seconds from
each other what is the output?
if it looks
A
B
A
B
than the monkey patching is correct if it looks like
A
B
B
B
then it is not. If it looks like
A
A
B
B
then we are not testing right. A,B are uuids.

Hello Richard,

Yes, I did a try but I didn't wanted to go very far with that. I was just
curious about giving it a try.

I had a problem with the database stuff I remember. I think this is the same
issue that you have.

web2py is no longer working with Python 2.4. Python 2.4 is old stuff now.

Here I wrote about using SQLite with Jython. I think this can help:

If you want to do your own "if form.accepts()" calls but also want it to 
handle the database stuff, you can use SQLFORM instead of Crud (see 
http://web2py.com/book/default/chapter/07#SQLFORM). You can also use the 
various Crud _onvalidation settings to specify actions to take between 
validation and acceptance (see 
http://web2py.com/book/default/chapter/07#Settings).

[web2py] How do I apply placeholder text to web2py forms?

[Carl]

I'm using custom forms in my views using this format:

I'd like to use HTML's placeholder attribute to input tags: e.g.,


Today: what are the ways to enable this? Obviously happy to drop the
{{=form.custom.widget.first_name}} format and use something else.

Tomorrow: might it be a good idea to add placeholder attribute to
db.Field() in a similar fashion to how 'label' has already been added?

I try to avoid ajax=True,ajax_trap=False option of LOAD() cause they seem to
conflict with the official jQuery UI Tabs plugin (loading pretty slow,
reload after submit with triggered validator even worse and try to load the
entire site before loading only my proper form).

I may not completly understand usage of component...

Thanks to help.

[web2py] Re: Befuddled by SQLTABLE linkto

[DenesL]

Hi Cliff,

the id field is handled as a special case inside SQLTABLE and the
linkto can only affect the _href portion of the anchor (A helper), not
the visible part.

But you can still do it:

rows=db(...).select(...)
t=SQLTABLE(rows)
for n,row in enumerate(rows):
  t[1][n][0][0] = A('Edit',_href=URL(r=request,args=[n]))

you can play with the values in row to customize it.

t[1] if the table's body
t[1][n] is the n-th row
t[1][n][0] is the first TD on that row
t[1][n][0][0] is the content (in this case the id value).

how would you implement a change to make it work?

Re: [web2py] response.write to transport index of the proper tabs from controller to the jQuery UI tabs plugin

[Anthony]

I don't think you want to call response.write in your controller -- it 
appends text to the response body, so you would be adding the text before 
the rest of the response body is rendered by the view. You also shouldn't 
need to call response.write from within the view, because you can just do 
{{=whatever_you_want_to_write}}.
 
Instead, you should be able to just pass a variable to the view. In your 
controller, return dict(form=form, tab=tab), and in your view, {{=tab}}.

Re: [web2py] response.write to transport index of the proper tabs from controller to the jQuery UI tabs plugin

[Richard Vézina]

Hello Anthony,

I can't use a var like you suggest since it popup in the component for
noting...

I am using session.MYVAR that seems to work... But I don't find the way to
get session vars in jQuery I try like this :


$(function() {
var $tabs = $( "#tabs" ).tabs();
var test1 = "{{=session.test1}}"; # OR like this :
<%{{=session.test1}}%> and with and without quote or double quote...
$tabs.tabs('select',  test1);
return false;
});


If I can get my variable value in jQuery do you think it a go work around?
