similar to: Caching::Sweeper Access to Controller

Hi, Why is cache_sweeper not a documented method? I was pretty sure it used to be, but I could be wrong. I can''t seem to find any information on it anymore in the online docs. As a side note, looking at the code for cache_sweeper it appears to only work with the :only option, not :except (ignores it)... what''s the reason for this? Thanks, Andrew

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to

So I''m trying to follow along in Chad Fowler''s Rails Recipes (recipe #59, Keeping track of who did what) and I simply want to access the current user from within my cache sweeper. Normally you just reference @current_user but that doesn''t seem to be the case here. In Chad''s example, he calls controller.session[:user]. What''s the Authlogic equivalent?

I''m using a cache sweeper class [1] to take care of some pretty complex sweeping. However, there is a problem with the current implementation. Namely, the sweeper gets called only when an action named in cache_sweeper is called using GET. As many methods where sweeper would be useful are using postback to send the form to the same action, this causes the cache to get swept when

I''m just getting my hands dirty with caching. The pages I want to cache have some user specific data on them (for example "log out"). That sent me down the route of fragment caching. One of the things I want to pagination is a paginated list. My question is how is pagination and query strings handled with fragment caching? Does each page get its own fragment and query string

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

I''ve enabled page caching on a site I''m currently constructing. The sweeper is called upon any changes made to the model, as expected. The sweeper code is as follows: class PersonSweeper < ActionController::Caching::Sweeper observe Person def after_update(person) expire_staff_page end def after_destroy(person) expire_staff_page end def

Folks, I''m going slightly crazy here - I implemented a Sweeper in an older app and used nearly the same exact code in my new app, yet I keep getting this ''value must be enumerable'' exception. Even after I cut most of the code away, I still get the error. If anyone can help, I would be much obliged. Notes: I''m using Engines... wonder if that could cause a

Hello everyone, I am currently struggling with the following issue that only seems to appear in my production environment: When attempting to send a mail from an ActionMailer the template location algorithm does not seem to pick up the corresponding template: ActionView::MissingTemplate (Missing template event_mailer/approval_requested_notification.erb in view path app/views):

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

[cross-posting to rails and typo lists] Hi, I''m tinkering with the code for typo, a rails-based blog engine. Typo has an XmlController with actions "rss" and "atom" which generate feed.xml files, and it uses a caches_page declaration to cache the files that get generated by those actions. It also has a Sweeper (Observer) class that expires those cached files when a

I''m trying to ''destroy'' a particular record of a table >From the controller side, i''ve found a list of possible records that i want deleted. ie. @chart = Chart.find(:all, :conditions => ["record_id = ?", param[''id''] ] ''id'' is passed into the controller and @chart is all the possible records that have

I was just wondering what about a report that I made almost 2 months ago: Active Record observers broken<https://rails.lighthouseapp.com/projects/8994/tickets/4087-activerecord-observers-cant-be-used-for-before-callbacks> I think it''s a pretty big bug. In Rails 3, creating an observer with a "before_save" callback (for instance) will result in all observed models being

After drawing many virtual blank stares in the IRC channel and finding zero results on the wiki for ''sweeper'' I''m left to wonder whether these are actually officially supported, or are on their way toward being deprecated. Is there a better way of expiring caches on model saves and deletions? Sincerely, Tom Lieber tom@alltom.com http://AllTom.com/

Trying to implement some sweepers to clean up my caching, but where do I put them? "ruby script/generate sweeeper" does nothing. -- Posted via http://www.ruby-forum.com/.

Can some1 help me on syntax with the find() function. I''m trying to pull up a table record, called chart, that has a particular field specified. ie chart has a field called record_id, which i know. How can i find the record that contains chart.record_id. something like chart = Chart.find(:conditions => "record_id = :id") this gives me an error. I''m passing

I''m working on an app that''s basically forms and that makes fairly heavy use of Ajax. As a result of the Ajax usage, if the visitor uses the back button they get the page as it was originally loaded, not as they left it. I''ve looked at the Sweeper documentation and can not tell for sure that it''ll do what I want, which is to force an unconditional reload from

Sorry, that name is a misnomer. However, I was excited to find that Ruby has a built in Observable module and I''m pretty bored, so I apologize in advance.... require ''observer'' # one who is observed class Celebrity include Observable attr_accessor :name attr_reader :is def is=(val) @is = val changed notify_observers(self) end end # one who
