global name DIV not defined

[Lars]

Hi,

I have this small code in the dashboard module:

from gluon.html import DIV
def get_dashboard():
    return DIV(
        DIV('Lorat ipsum etc', _class='dashboard alert'),
        _class='center-box').xml()

and this one in default.py :

def index():
    from modelling.dashboard import get_dashboard
    dashboard = get_dashboard()
    return dict(message=message, dashboard=dashboard)

And I noticed that if I refresh the page to quickly sometimes I have the error :
global name DIV is not defined

or some other, the css is not defined ? Both never happens when the DIV is defined in default.py.

Could anybody figure why ? And how to avoid this ?

Thank you,

I think you want to import from sqlhtml :

Try like this :

from gluon.sqlhtml import *

No, DIV is in gluon.html.

So the problem is from .xml() than??

Actually it comes from T, the issue remains even with no xml() or XML involved.

Sorry but I reduced the function to the wrong line : I had a T = current.T at the beginning of get_dashboard() which
deletion didn't suppress the issue.

It seems that an involuntary (my bad) spelling of the returned string (message='Lorat ..') created multiple versions of the message in LANG.py which then create a bad dictionary that contains different possible translations for the same item in uwsgi cache.

Rewrite (sanitize) lang.py by hand and restart uwsgi does the trick.

Thank you

You can pass T() to module or use current.T(), I think the later is the proper way to do now as current wasn't existing before we had to pass request, T(), etc...

http://web2py.com/books/default/chapter/29/04/the-core#API

"Other objects and modules are defined in the libraries, but they are not automatically imported since they are not used as often.

The core API entities in the web2py execution environment are request, response, session, cache, URL, HTTP, redirect and Tand are discussed below."

Then a little further :

current.request, response, etc

[Lars]

I don't now about before (I don't have much experience) but the book specifies not to pass current at module level, only in functions.
Thanks for the hint anyway. :)
