Dipping my toes in the waters of FormEncode today. Basically decided I needed a break from financial aspects, so spent some time roughing out a simple list and add view for Inventory objects (in this particular case, phone numbers/DIDs). Most of the work was:

Figuring out that All and Any values are applied in reverse order. Argh.

Figuring out error handling with the error_handler decorator. Basically you decorate the post-handling method with:

@turbogears.error_handler( index )

where index is the method that handles the display of the validation errors. Normally that will be the same page as produced the post. You add a tg_errors=None to the signature of that page and then you can pass that value into your template for formatting. You can check for errors with py:if="errors" and you can pull out errors for a given field by parameter name.

Figuring out that FormEncode (or maybe it was CherryPy) automatically turns 'select.num' parameters into dictionaries as 'select': {'num': value,...}.

Still need the ability to search for a given number and to display the assigned configuration... well, really, need the whole application still, this was just a spike test, really.
