Re: A table with average & total row
I would tend to agree with the prior comments that you do things like
counting at the database, so you would put things like counts and
totals in your model, or in the controller logic by adding the
appropriate calls.
You can add a calculated field like $amount in your model's afterFind
method and it works really nicely if you don't need to save it in the
DB.
function afterFind($results) {
// Create an amount pseudofield using
foreach ($results as $key => $val) {
if (isset($val['Invoice']['price']) && isset($val
['Invoice']['quantity'])) {
$results[$key]['Invoice']['amount'] = $val['Invoice']
['price'] * $val['Invoice']['quantity']
}
}
return $results;
}

Re: A table with average & total row
Depends. If you can do it in DB without performance loss, that's the best way. If not, view is good enough. I tend to do as much as possible in the database, because the damn thing is optimized to work with (large) sets of data. But in the end, if that's not an option for you, whatever gets the job done... :-) On Dec 23, 6:31 pm, mathie wrote: > Hello, > > This is a design question on MVC separation.

A table with average & total row
Hello, This is a design question on MVC separation. Say I need to display a table with many rows, then a total and an average row. Should the calculation of this total/average be done in the view (in the loop) or in the controller (after getting the rows from DB)? A related question. For an invoice: $amount = $price * $quantity; Could that be in the view or not? Basically I guess my question: what is considered view logic?
