Poking my nose into Rails 3, I notice that the class of the returned
values of these two calls is not the same:
Model.all ==> returns Array
Model.where(['1 = 1']) ==> returns ActiveRecord::Relation
Is there a reason this is this way? What I would think is a common use case:
Model.all.order("somefield DESC")
fails with NoMethodError: undefined method 'order' for
#<Array:xxxxxxx> (where it works fine with the "where 1=1" instead)
The I guess older style "Model.find(:all)" also returns an array so it
too is un-scope-able in the above way.
I *can* do Model.order("somefield DESC"), but that just seems
inconsistent (albeit handy).
So what is conceptually different about Model.all.order() compared to
Model.order() and Model.where(['1 = 1']).order()?
Thanks...
