I've set up Kaminari so that it can accurately paginate by post title if i do this: 

```
def index
...
@posts = Post.order('title').page(params[:page]).per(5)
...
end

```

i also have <% paginate %> in the view

but if I try something like this

```
@posts = Post.order('pageviews').page(params[:page]).per(5)

```

it stops working. There are no bugs or errors, but it just appears to be sorted arbitrarily. Possibly by date. How come?
