Thanks a lot, Sergio
I'm almost there, the problem is that I'm still facing is the
following one: I want to update the net_amount column in my model
whenever the amount column or the vat column changes in the following
way: net_amount = amount * (1.0 + vat/100.0). The amount column is
formatted in the form as a currency.
To this purpose I overrode render_field.js.rjs as you said (with minor
modifications):
page << render(:super)
net_amount_id =
active_scaffold_input_options(active_scaffold_config.columns[:net_amount],
params[:scope])[:id]
amount_id =
active_scaffold_input_options(active_scaffold_config.columns[:amount],
params[:scope])[:id]
vat_id =
active_scaffold_input_options(active_scaffold_config.columns[:vat],
params[:scope])[:id]
page << "$('#{net_amount_id}').value =
$F('#{amount_id}').gsub(',','.').gsub('€','') * (1.0 + $F('#{vat_id}')/
100.0)" + ' €'"
I can't use @record.amount since this can be called when the vat
column is modified, and then I don't have that value. The gsubs in the
last line are hideous, but that gets rid of the separator and the
currency symbol in amount (please let me know if you can think of a
more elegant way of doing this)
The problem is that I can't figure out how to display back that value
in the form as a currency (in Spanish format, that is 1,23 €) in a
similar fashion to what number_to_currency would display.
