You actually did right in your second experiment. The way you are supposed to do it is by passing the `value` to the form, not trying to set attributes of single fields. See https://tw2core.readthedocs.io/en/latest/widget/#widget-value
So in practice the right way would be to do: form(value=dict(tf_url=X)).display() or form.display(value=dict(tf_url=X)) On Tue, May 7, 2019 at 4:48 PM Mikhail <[email protected]> wrote: > Hello again! > Finally I have time to port my project to new version of TurboGears.
