Paul, why the "to_python()" ?? If you have an SQLObject (let's call it Person) with three fields in it (firstname, lastname, homephone), you can add a fieldset to your widget form called "personinfo" and then in your controller save the data into a new Person object like this: p = Person(**personinfo). Am I missing something? Are you worried about a security issue? > While I'm here, a couple of other questions: > 1) Can you build a widget form automatically from an SQLObject?

FastDataController does this, take a look at this to get started, and use the source! http://www.turbogears.org/widgets/tutorials/DataGridWidget.html (here's a tip that's probably not listed on that page -- you can get your fields to appear on the form in a certain order by adding a member variable called "field_order" to your SQLObject class. Check out the SQLObject docs on how to use it) > 2) Is it possible to combine a widgetform and a dataobject, into a > single object?

I think the FastData stuff is what you're looking for. Once you've got it working, make a copy of the fastdata source and call it MyFastData (or something), so you can change the source to display the fields using any custom widgets you might have. Start by looking in the "fields_for" function... hope this helps! -ian --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
