rails4 after caching query still runs

问题 I have a rails 4 app and trying to implement caching. I use the @profiles_sidebar.first cache key for checking if new user was created. I'm not sure if this is ok, since there still is a db query. Is this the preferred mechanism to check if caching needs to be expired? Am I doing well? <% cache(@profiles_sidebar.first) do %> <% @profiles_sidebar.each do |profile| %> <%= link_to user_path(profile.user) do %> <%= truncate(profile.full_name, length: 25) %> <%= truncate(profile.company, length:25

rails 4 cache expiration not working

问题 In my rails app I'm trying to use nested caches, but my cache-key is not expiring when user.profile.full_name is changed. So when user changes his/her name the full_name displayed by _profile_product.html.erb remains the old one. How should I change the key? profiles/show.html.erb <% cache(@profile) do %> #this is the profile info and the cache key expires properly when @profile.full_name changes <%= @profile.full_name %> ..... <% end %> <% if @profile.user.products.any? %> #not nested in the

rails4 caching naming conventions

问题 I have a rails 4 app. I have to differentiate the different cache keys somehow but don't know the naming conventions. FIRST EXAMPLE: I have a task model with index , completed_tasks and incoming_tasks actions. A have the same instance name ( @tasks ) though because of the pagination. At the moment the cache-keys are named like below. My questions: 1. Is the cache-key structure good enough? 2. Is it important in which order I put the parts of the key in the array? For example [@tasks.map(&:id)

Caching a Drupal site with session-specific data on every page

问题 We have a site written in Drupal 6. We want to use Drupal's caching mechanism to improve performance, but when we turned it on, we found problems because our site has session data displayed on every page. Drupal's caching system only works for static content page, and our session data effectively means that none of our pages are static. We've come up with two solutions to this: Rewrite the block that shows the session data such that it loads the non-static data using Ajax, so that the main

Optimize APC Caching

问题 here is a link to how my APC is running : [removed] As you can see, it fills up pretty quickly and my Cache Full Count goes over 1000 sometimes My website uses Wordpress. I notice that every time I make a new post or edit a post, 2 things happen. 1) APC Memory "USED" resets 2) I get a whole lot of Fragments I've tried giving more Memory to APC (512 mb) but then it crashes sometimes, it seems 384 is best. I also have a Cron job that restarts apache, clearing all APC of fragments and used

rails leaving out some parts from fragment caching

由 爱⌒轻易说出口 提交于 2019-11-29 16:02:28
I have a rails 4 app using pundit gem for authorization. If I do russian-doll fragment caching like the code below, the conditional statement used for authorization will be also cached, which is not good, since edit/delete buttons should only be available for the post.user . What is the good way to get around this? Should I split the cache into smaller parts or is there a way to exclude some parts of the caching? What's the rails convention in this case? index.html.erb <% cache ["posts-index", @posts.map(&:id), @posts.map(&:updated_at).max, @posts.map {|post| post.user.profile.updated_at}.max]
