Good work, it looks like you've stubbed out a lot of functions. When
you do get it to work, I'd love to list the models that need stubbing in
the documentation.
It may be easier to add a hobo_model declaration to your pseudo-model.
In that case, you would have to stub out the ActiveRecord functions
rather than the Hobo functions. Which is easier, I'm not sure, but
it's an option, anyways.
The error is saying that Hobo cannot find an input tag that will render
file, it thinks that file is an Object.
Perhaps you can make a reader function for file that coerces it to a
type that Hobo does know about, like so:
def file
@file.to_s
end
Or you could coerce it to rich type or something.

Hi!
I'm offering an import form for my users. The import model itself
isn't a real ActiveRecord model. How can I benefit from all of
DRYML's goodies, without using a hobo_model?
Using a hobo controller, I have this error when rendering the new
form:
HoboError in ImportsController#new
No input tag for file:Object (this=nil)

I have mostly faked my way out of everything. Notice the model at the
bottom. But that error has me stumped... I'm probably returning a bad
value from some method.
Thanks!
