rails的before_filter,如果except子controller中的action skip_filter
如题,在http://*.com/questions/2390178/skip-before-filter-in-rails 找到了答案。
问:
I have three controllers: dog
, cat
, and horse
.
These controllers all inherit from the controller animal
.
In the controller animal
, I have a before filter that authenticates a user as such:
before_filter :authenticate def authenticate authenticate_or_request_with_http_basic do |name, password| name == "foo" && password == "bar" end end
In the show
action of dog
, I need to have open access to all users (skip the authentication).
If I were to write the authentication separately for dog
, I could do something like this:
before_filter :authenticate, :except => :show
But since dog
inherits from animal
, I do not have access to the controller-specific actions. Adding :except => :show
in the animal
controller will not only skip authentication for the show
action of dog
, but also that of cat
and horse
. This behavior is not desired.
How can I skip the authentication only for the show
action of dog
while still inheriting from animal
?
答:
class Dog < Animal skip_before_filter :authenticate end
