Hey,

I have a 2 model form. Vehicle which accepts\_nested\_attributes\_for  
Images.

The form has a single File input field for an image. The form does not  
require a file to process (Works in Dev fine).

In cucumber I fill out some fields then submit. I’m getting back  
Validation errors from the Image model. “Data file name must be set.”  
But I’m not submitting an image so the Image model should never be  
called. Why is cucumber sending data that’s getting to the nested  
attributes in vehicle?

Cheers,
