Hah, yeah, the bracket is missing. And in Camping, the equivalent of
Rails' params is @input.

Thanks, I've gotten it to work.
On this part though: @user = User.new params[:user
Is the closing bracket missing? Is params something from Rails that
allows you to create the user instance variable all in one line
instead of doing something like this:
@user = User.new(
:id = input.id,
:name = input.name,
...
)
Can I use it in a camping app relatively easily?

In my create actions, I customarily do like
@user = User.new params[:user
if @user.save
...
else

end
But update_attributes should also return true or false, I believe.

So, in my crud controllers, should I be using calls to save instead of
create and update_attributes? As those just return the object, and not
true of false based on my validations.

Yeah, but in practice, you'd call @user.save, which internally calls
#valid?, and returns true or false on whether the object was saved or
not. If the object wasn't saved, @user.errors is populated with the
error messages.

I'm a little rusty on AR at the moment, but I think it looks something
like
this:
In the controller:
if @user.valid?
# everything is fine
else
# ops! @user.errors contains the errors
end

Can ActiveRecord::Validations::ClassMethods be used to provide
feedback to the user? I noticed the tepee example uses
validates_uniqueness_of . If the title isn't unique however nothing
is written and the user is never notified.
Does anyone have an example or two of how I could go about informing
the user that the title they entered was not unique and they need to
enter another?
