Rails 4 CRUD Update Successful but not saved to Database - ruby-on-rails

Question

I am experiencing a really weird issue in my rails 4 app. I've created a CRUD operation called FOO. All sections work as one would expect it to, except for the Update operation.
The FOO model has 4 Attributes:
title
body
author
status
When I load the Update form, the model is loaded into the form as it should be. The update action returns a "SUCCESS" status if a valid form is submitted, but here is the issue: Only the "Title" attribute is ever updated. All the other attributes remain unchanged. If I Update them one-by-one, they also do not change.
Here is my FooController code:
def update
if #foo.validate( params[ :foo ] )
#foo.save
respond_with( #foo, location: root_path )
else
render :edit
end
end
I am using the Reform GEM instead of Strong Params:
class FooForm < ApplicationForm
property :title
property :body
property :author
property :status
end
And I'm loading the #foo instance in my controller like this:
before_action :load_form_instance, only: [ :edit, :update ]
def load_form_instance
#foo = FooForm.new( Foo.find( params[ :id ]) )
end
I have tested overwriting these values from my Rails console and that seems to work just fine.
Does anybody have any idea where things might be going wrong?
UPDATE
Here is my development LOG as per a request below:
