Hi, I got very small app that has user part and admin part. The problem is that after a while the sessions table has ~150mb. I don''t really need to store any user data in the session for the user part. I only need it for the admin part. Can I simply turn session off in controllers from the user part? Are there any drawbacks of turning the session off? Regards

Hi, I''m using Rails 2.1.2. and I wanted to switch ActiveResource format to JSON and thought that it will work smoothly, but unfortunately it wasn''t the case. XML and JSON formats generate different objects: XML version #<User:0xb7658440 @prefix_options={}, @attributes={"created_at"=>Mon Nov 28 11...}> JSON version #<User:0xb746af5c @prefix_options={},

Hi, I''m using CountryCodes to get countries list for select box. It provides self.countries_for_select(*args) method exactly for this purpose. I''m using it in only one place in my view. So I was thinking about caching this data somehow, so it won''t have to be recreated every time the page is loaded. The problem is that the plugin initializes its main @countries

Hi, I got Image model that has_attachment and belongs_to 2 other models via polymorphic association. The problem is that I''d like to customize has_attachment options (resize image) depending on which model the Image is related to - i.e. if Image belongs to Article it should be resized using different settings than if it belongs to Header. Is there a smart way to do it or do I have to

Hi, We''re trying to rewrite veeeery old Rails app that we successfully managed to move to 1.2.6 and now we''re trying with 2.1.0. One of the problems is caused by :include in AR.find.

There are few issues with the current ActiveModel::Errors class. Firstly, when an error is added to ActiveModel::Errors class via #add method (https://github.com/rails/rails/blob/master/activemodel/lib/active_model/errors.rb#L294) its translation is added. It should not be translated when being added, but only when being read. The second issue is a bit bigger. We''d like to create

Hi, I''m using deprec+capistrano to deploy my app. The problem is that everything is assigned to the user (and his group) that the application was deployed by. This causes problems with i.e. caching, because mongrel can''t write inside public dir. How should I set permissions for public directory? --~--~---------~--~----~------------~-------~--~----~ You received this message

Hi, I''m using this tutorial: http://blog.hasmanythrough.com/2006/3/23/dirt-simple-rcss-templates to make dynamic CSS files. However I can''t figure out how expire cached CSS files. Here''s my code: http://pastie.caboo.se/181021. Most of it is copied from the tutorial. Files are cached properly - i.e. <%= stylesheet_link_tag "main" %> generates

Hi, I got a title_tag helper that renders default page title or title provided by content_for block, if such block is present. Currently I call this method like this: "title_tag(yield(:title))".

Hi, I''m doing my first plugin, based on attachment_fu structure. Here''s the code: http://pastie.caboo.se/200797. The problem is that the meta_tag method doesn''t seem to be overwritten. I can call model_instance.original_meta_tag and it return same thing as model_instance.meta_tag, so the aliasing works. I can call model_instance.foo and it correctly returns class of

Hi, just found out small problem with Rails 2.1.

Hi, to send an email with ar_mailer I need to generate it and save it to the db, right? Currently the code looks very simple: Newsletter.recepients.each do |recepient| NewsletterMailer.deliver_dedicated(request, recepient, newsletter) end But for i.e. 30000 receivers it''s going to take a long while anyway. Should I create them somehow in the background using BackgrounDRb or something

I''m trying to use Bundler for existing Rails 2.3.5 app and got a very strange problem. The problem is that on the very first request only the contents of the action view file are rendered - i.e. when loading the home page (controller: home, action: index) I get only contents of the app/views/ home/index.html.haml file as the response with no layout at all. On the second and on subsequent

Hi, having i.e. a post model that has many categories - is it possible for member routes like i.e. post_path(post) to generate path like "/ posts/:post_category_name/:post_id" without manually passing the category param? Does anyone know if there''s a gem or if I can simply override the post_url method to automatically set category from post object? The best I could get right
