Hi,
I'm trying to use sweepers for the first time and got a problem - I
get "undefined method `merge' for "/signature/
f2d7c7c66450b169.html":String". The "/signature/f2d7c7c66450b169.html"
part of the error message is the cached page.
Here's my sweeper:
class FooSweeper < ActionController::Caching::Sweeper
observe Foo
def after_save(foo)
expire_cache(foo)
end
def after_destroy(foo)
expire_cache(foo)
end
def expire_cache(foo)
expire_page signature_path(:opaque_id => foo.opaque_id) # line 13
expire_page signature_image_path(:opaque_id => foo.opaque_id)
end
end
The signature_path(:opaque_id => string) generates "/signature/
string.html" route, so this part works correctly.
Here's stack trace:
.../vendor/rails/actionpack/lib/action_controller/caching.rb:125:in
`expire_page'
.../vendor/rails/actionpack/lib/action_controller/caching.rb:612:in
`send'
.../vendor/rails/actionpack/lib/action_controller/caching.rb:612:in

#{RAILS_ROOT}/app/sweepers/foo_sweeper.rb:13:in `expire_cache'
#{RAILS_ROOT}/app/sweepers/foo_sweeper.rb:5:in `after_save'
.../app/controllers/foo_controller.rb:61:in `unsubscribe'
Any ideas what can be wrong? I'm using Rails 1.2.6.
Thanks in advance
