I''m trying to move some of my application''s code into a
plugin,
specifically the part that deals with web analytics. Some of the
features allow the controller to fire events that get displayed in the
views as JS code through a partial or helper. I''m currently doing this
with instance variables, but when I move it to a class or instance
variable of my plugin class, it persists between requests. I guess
this makes sense because the plugin is loaded on startup.
What I have working is making it an instance variable of
ApplicationController:
class MyPlugin
ApplicationController.instance_variable_set("@my_plugin_event",
nil)
end
which is cleared on every request. It works, but I feel like I''m
working against the grain here and doing something wrong.
Is what I''m doing OK, or is there a better way? To make it clear, I
want to be able to do something like
"notice_event(''blah'')" in the
controller of the main application, and have the plugin''s helper know
about "blah" for the current request, but not the next request.
Thanks
Sean

Re: Clearing a plugins instance variables on each request
It would seem to do what I''m looking for, though was the flash meant for objects? Either way, I''ll look at the implementation to see if I can use similar methods.

Re: Re: Clearing a plugins instance variables on each request
Sean, I think flash.now would be fine for objects because it is only there during the request and is not persisted.
