Python GUI Programming with Tkinter

DataRecordForm creation

First, let's fix our DataRecordForm instantiation in Application.__init__():

        # The data record form
        self.recordform = v.DataRecordForm(
            self, self.data_model.fields, self.settings,             self.callbacks)

Previously, we'd pulled the fields argument from the static class property of CSVModel. We need to pull it from our data model instance instead, since the instance is setting up some values.
