Anthony,
I just tested it again, form.widget.fieldname WORKS with _readonly. Earlier
i had 'total' field defined in Field() with writable=True, somehow it
didn't like it when i set this field _readonly= True. Thank you so much
(also to Peter and Villas)!
(I changed the test table to invoice)
In controller:
row = db.invoice(1)
form = SQLFORM(db.invoice, row, formstyle='table2cols')
form.custom.widget.total['_readonly'] = True
In view:
{{=form.custom.begin}}
Invoice Id: <div>{{=form.custom.widget.id}}</div>
Customer: <div>{{=form.custom.widget.customer}} </div>
Project Name: <div>{{=form.custom.widget.project_name}}</div>
Total: <div>{{=form.custom.widget.total}}</div>
{{=form.custom.submit}}
{{=form.custom.end}}
<script>
jQuery(document).ready(function(){
jQuery('#invoice_project_name').change(function(){
var invoice_total = jQuery('#invoice_total').val();
alert("invoice_total = " + invoice_total);
jQuery('#invoice_total').val('4000');
});
});
</script>
