Problem with built-in named scope all

Rails
1

Hello,

I’m having a problem with the built-in all scope. For example in my
Subscription model,

Subscription.all.count
NoMethodError: undefined method `count’ for #Array:0xb5dce7f8
from (irb):46
from :0

However, my own version of all defined in the model simply as
“named_scope :everything” works fine

Subscription.everything.count
=> 849

I also cannot chain scopes onto all

Subscription.all.active.count
NoMethodError: undefined method `active’ for #Array:0xb5a80268
from (irb):50
from :0

But

Subscription.everything.active.count
=> 611

I’m relatively new to Rails so any insights people can give would be
greatly appreciated. Thanks!

My environment is

[root@localhost trunk]# gem -v

Since .all internally is doing a find(:all), it’s returning an array,
not an proxy like named_scope and the association methods do. So
although it might look like a named scope, it actually isn’t.

So instead of Subscription.all.count, you have to do
Subscription.count. Instead of Subscription.all.active.count, just do
Subscription.active.count. Having the “all” in there is redundant
anyway, although I sympathize with the concept that it might feel more
consistent that way.
