[Zope] can zope and grok be a solution for a desktop like interractive web app

2009-05-05 Thread Krishnakant
hello all,
Seems my problem with reports is almost solved and I know that office
integration is also possible with zope.

Now my question is while I was reading grok tutorials, I realise that I
could not quite find some widgets which can do dynamic self updating or
database based validations.

For example if a user is making an invoice, the field holding entered
quantity must quickly query the db for the available current stock and
there has to be an error message which says you don't have sufficient
stock for the given item .

I don't see such widgets available in grok.  Am I missing some part?

I believe some ajax like functionality is needed here.

Further more, I will also need to develop drop down menus and such other
widgets.  I had discovered toscawidgets but get the impression that they
can be used on pylons and turbogears but not on zope?

Is this true?

happy hacking.
Krishnakant.

Eeee, no, they are HTML widgets. You might as well ask for
SQL-statements that generate HTML widgets. It just doesn't make any
sense.

 For example if a user is making an invoice, the field holding entered
 quantity must quickly query the db for the available current stock and
 there has to be an error message which says you don't have sufficient
 stock for the given item .

Yes, you want to make a Javascript app. That's fine and good. For that
you would likely want some sort of Ajax library. Grok isn't an Ajax
library, but you can use Ajax libraries with Grok if you wish.

 I believe some ajax like functionality is needed here.

Exactly.
