Question

I’m using custom widget in my crud form like this:

{{=form.custom.begin}}
{{if condition:}}
    {{=form.custom.widget.field1}}
{{pass}}
{{=form.custom.submit}}
{{=form.custom.end}}

field1 has a relationship to the auth_user table. In my controller I have:

form.custom.widget['field1'] = dropdown

if not condition:
    db.admission.field1.readable = db.admission.field1.writable = False
    db.admission.field1.default = auth.user.id

I want the widget to show only when the condition is true. If the condition is not true, I want field1 to default to the current logged-in user. But, when the condition is not true, I get the error:

field1 error: value not in database

What am I doing wrong?

Answer 1

Set the readable and writable attributes before creating the form — in that case, field1 will simply be excluded from the form automatically, and you won’t have to bother with creating a custom form and explicitly including/excluding it.
