Hi Enrique,
Why don't you try to make a virtual field in the PlanOperativo model and
sum it there?
def total
progreso_indicadors.sum(:cant)
end
And later you can call the table-plus:
<table-plus fields="total"/>
or maybe you just want something more simple:
<this.total/>
About using custom Ajax forms to make a query and return a result I
recommend you this manual: http://cookbook.hobocentral.net/manual/ajax.
Ajax is a bit crazy when you start but with a lot of Firebug and
patience you can certainly make it :)
Regards,
Ignacio
