Thank Anthony,
The error was getting just because I used {{=sum(b)}} in my view. now this
works fine.

Please show your exact code and
@Anthony, This gives me an error.becouse of some values float type in the
field.
('float' object is not iterable)
How can I successfully sum all the values within this solution?
Thanks

This is more efficient because the database calculates the sum for you and
you don't have to load all of the database records into the web2py process:
Thanks to all for your support
@Anthony, I have done this way!! That provie all values sum which is having
in grid.
#controller.py
grid = SQLFROM.grid(query,..,...)
a = grid.__dict__
b = sum([int(i.number_of_bags) for i in a['dbset'].select()])
Please, Let let me know if any other way to do

Having the database do it is most efficient -- you neither have to get all
the data from the database into the
How about JavaScript?

You should do a separate query and have the database calculate the sum for
you (rather than loading all the records from the database and doing the
calculation in Python).
