Again, you don't *have* to call form.process() in the controller -- you can
call it in the view (though you probably shouldn't). However, if you want
web2py to validate the form, you obviously have to create a form object for
it to validate. There's nothing wrong with generating a form object in the
controller for purposes of validation/database inserts but use completely
custom HTML in the view -- as long as the HTML matches up with the form
object DOM (i.e., same input variable names). Note, web2py includes a
hidden _formname field, and optionally a hidden _formkey field (which you
should use because it protects against CSRF attacks). Once you create the
form in the controller, you can access those values via form.formkey and
form.formname in order to insert them into your HTML (or just insert
{{=form.hidden_fields()}} somewhere in your HTML form).
