Totals row

[gfaraj]

I would like to add a row at the end that shows a total for one or more columns. Is that possible?

[leikind]

g.last_row do |rec|
  # return your html as a string
end

Was wondering if there was something that did it automatically, but that works. Thanks!

Wait... how would I retrieve the values to sum for a total?

[leikind]

how about using a variable in the block?

[leikind]

something like this

<% sum = 0%>
<% grid() do |g|

  g.column do |rec|
    sum += rec.something

    rec.whatever
  end

  g.last_row do |rec|
    '<tr><td>' + sum.to_s + '</td></tr>'
   end
end %>

Oh, yeah that's a good idea. Thanks.
