Provide default value to a form widget

[mettwoch]

Hi,

I've seen the new TG 1.05 feature to provide a function to the default
value of a widget. Please help me I'm confused now and can't see how
to use that. Let's say that I've a controller method exposed and that
gets an argument called "code". How can I provide the value of that
argument as a default to a TextField widget contained in a TableForm
exposed by that controller method.

    SomeFormFields(WidgetsList):
        code = TextField()

    someForm = TableForm(fields = SomeFormFields())

    @expose(template = "someForm")
    def someMethod(self, code):
        ...
        return dict(someForm = someForm)

Thanks for any hint

Marc

In your controller:

return dict(someForm=someForm, value=dict(code=code))

In your kid template or whatever (just adapte to your case):

<span py:content="someForm.display(value=value)">content that will be
replaced</span>
