How do you detect if ActiveRecord ''update'' fails?
So I''m updating multiple model objects in one go with something like
this in my controller:
=> Photo.update(params[:photo].keys, params[:photo].values)
When the update fails due to validation errors, how do I detect it?
The Rails API says:
"If the save fails under validations, the unsaved object is still
returned."
So I can''t simply do this:

set empty values as null in the database
Le''s say that I have a table called people and the column middle_name is
nullable. If the user enters say blank or empty space then in the database
it is recorded as empty space. I would like in all my models all empty
spaces to be recorded as null.
I guess I can write a plugin which will do so for all the models but I''m
sure something like that should already be existing.I

instance variables in templates
Hey all,
Well... hmm... feeling pretty stupid here...
For some reason my controller instance variables are not displaying
in my templates. I''ve boiled it down to this test case.
class Rss::FilmController < ApplicationController
def display
@time = Time.now
end
end
and the template:
<html>

Test oddities
Can someone explain why a instance variable cannot be changed through an
association under rspec/factory_girl? An example is in this gist<https://gist.github.com/2484336>
.
All tests pass except the last. All the steps pass in the console.
