The input field 'username' was not expected.

[Robert Ramsay]

I'm using RUM 0.2 and pylons. I can create and view my models fine.
But when I try to edit anything it says that the form is not valid and
"The Input field 'username' was not expected."

[Michael Brickenstein]

Dear Robert!
Can you post a more detailed stack trace?
Thanks,
Michael

I'd love to, how do I get a stack trace for RUM?

My first issue is with form validation. But if I hit submit again it
will say that the entry has been successfully completed. But then
checking back at the index, the entry is empty. And when attempting to
delete I actually get a halting error with stack trace (attached
below).

I will give some context though. In our pylons app we heavily use
reflection. In fact the model properties are defined using
__table_args__ = {'autoload:True'}. This may be causing the issue, I
don't know.

Hi Robert!
Sorry, the delete error is independent from the other problems (I have a look at it).

Regarding the username problem.
RUM constructs the form twice
once on the action
edit (form display)
once on
update (validation and update values).

It generates a toscawidgets form, which validates with a formencode Schema.
On of the parameters of this schema is to raise an error when there appear unexpected arguments.

So, I suppose, that two different forms are generated, one with username and one without.
Do you have any customizations, policy, widgets...?
You should provide rum with the same rules for edit and update.

Cheers,
Michael

Hi Robert!

The explanation is fully correct, but both errors are not specific to your application.

Before christmas I implemented the wonderful 'join'-feature (you will see)
on heavy user requirements and as it
handles common problems in a good way.
Unfortunately, I had to change nearly the complete rum source code
to adapt to the functionality.

While I have already fixed most bugs, these hit me surprisingly.

Many thanks for the bug reports!!!

I hope that I can give an update until the end of the day.

Cheers,
Michael

Dear Robert!

Thanks again for your feedback and sorry for your inconveniences.

You can find
an update in our repository
or on PYPI
easy_install -U rum

Cheers,
Michael

Thanks for the quick response. pip and easy_install now install
rum-0.4dev-20110107. And I get the following stacktrace
