Well I was thinking that, BUT: I'm ALMOST convinced there is a bug in the
latest web2py:
CODE
------------------------------------------------------------------------------------------------------------------------------
Snippet of controllers/default.py
session.company = request.vars['Company']
Company_ID = "This is a %s of type %s " % (session.company,
type(session.company))
Company_ID = session.company
DbRows =
db(db.company.company_number==Company_ID).select(db.company.company_name).first()
# Co_Name = DbRows['company_name']
session.company_data = DbRows
>From view/default/company_login.html:
{{extend 'layout.html'}}
<!-- {{session.company = request.vars['Company']}} -->
<INPUT type="button" value="HOME"
onclick="location.href='{{=URL('index')}}'"/>
<a href="{{=URL('index')}}">HOME</a>
<h4>Input form</h4>
{{=form}}
<h4 style="margin:0;">Submitted variables</h4>
{{=BEAUTIFY(request.vars)}}
{{=(request.vars)}}
<h4 style="margin:0;">Company vars: {{=(request.vars['Company'])}}</h4>
<h4 style="margin:0;">Company session: {{=(session.company)}}</h4>
<h4 style="margin:0;">session data: {{=(session.company_data)}}</h4>
Will Display The following:
(top of form omitted ...)
..... Submitted variables
Company :
5
password :
makeit1
username :
b...@linux4ms.net
<Storage {'username': 'b...@linux4ms.net', 'Company': '5', 'password':
'makeit1', '_formkey': '65ee8396-aac0-4b5c-a255-00be7e7b01ca', '_formname':
'no_table/create'}> Company vars: 5 Company session: 5 session data: <Row
{'company_name': 'Number 5 Company'}>
___________________________________________________________________________________________________________________________________
However, any type of referencing or attempt to do anything with either
session.company_date or DbRows
always gives a "Nonetype" error of various subtypes (such as __getitem__)
Uncommenting the controller code of "# Co_Name = DbRows['company_name']"
gives the error:

As one can see , the Row item exists, it just seems there is no way to get
to it ...
Any other ideas ?
