similar to: Some Basic Questions

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

First let me say that Rails caching is very very cool. The traffic (and responsiveness) I''ve saved by added 10 lines of ruby code would be enourmous, if I actually had traffic... ;) Sweepers as observers are great, btw. Since every page of my side is dynamic, once I did some DB optimization I''m caching the content of the index page which was taking the bulk of the time to load

A couple questions: 1) How does rails no if you are in your test, dev or production environment? 2) Does anyone have an actionMailer server settings that will work on your standard local machine? I will use the one provided for my textdrive account but for testing on my machine I am getting connection refused. Thanks. Your Friend, Jonathan Kopanas http://www.kopanas.com

It seems odd to me that the layout is processesed after the view. When I set a variable inside the view it does not have an impact on the layout file. But when I set it in the controller it does. Is this the way it works or is it possible that I am doing something wrong?

After I have uploaded my app where do I specify that my app should now use production environment settings and not development? Can that be done dynamically so that I don''t have to reset a value once I upload website? Thanks for your help!

Hello, I am trying to edit and update all records of table ?intersts? (id, name, description) on one page and has no good idea how to do it right, when updating one record per page it?s ok The question is: what statement instead Interest.update_all(params[:interest]) in controller need to use to successfully update the database table by data passing to controller in parameter ?interest??

Recently my application has refused to start on my production environment. The setup is debian(unstable)/apache2/fastcgi/mysql Rails 0.10 (upgrading to 0.10.1 as we speak) When I first start up apache the machine grinds to a crawl starting up the dispatch.cfi processes. It''s a VPS with 256M of ram, but still (in addition to user time) it''s spending 30% of time in system

Where in the application would you suggest I set default values that are read for every action and in some cases changed and somecases not. Basically on some pages I am getting the <title> from the DB and if not I want to put a default one up. Any suggestions?

I have a controller method called update_all that grabs parameters for about 30 form fields and saves them to the database. My current code looks to see if there is a string in params[] for each form field (two fields for each SelfEvaluationItem) and saves the updated self_evaluation_answer if a string is available. Since this is iterated code, I am almost certain that this generates 30 or so

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database. For example, I have the following models: class Parent < ActiveRecord::Base has_many :children, :conditions => "deleted_at IS NULL" end class Child < ActiveRecord::Base belongs_to :parent, :counter_cache => true end With the following

I have made additional progress with regard to performance. My latest data: configuration 1: r121.latest configuration 2: r121p.latest page c1 real c2 real c1 r/s c2 r/s c1/c2 /empty/index 6.75525 1.71983 148.0 581.5 3.93 /welcome/index 6.89044 1.89244 145.1 528.4 3.64 /rezept/index 4.99573

Reading the Agile book, I can''t find a single command to save a collection. The save command seems to operate on only individual objects. Lets say I have a collection that I have received from a find_all command. I want to go through and change some attributes in various objects in the collection. Then I want to resave the whole collection back to the database. I don''t think

I have added roles and roles_users table and updated the model so that my users can have multiple roles. ("Admin" role does always have id = 1). I have added these methods to my application controller. <code> helper_method :is_admin? helper_method :is_user? def is_admin? if @session[''user''] @session[''user''].roles.find(1)

Ahoy, having a bit of difficulty w/ the acts as taggable GEM. I was able to create a tagcloud, but now i want to filter items by tags. in my controller i have def show_tagged_with <-- snip snip --> @items = Item.find_tagged_with( :any => params[:tag_name]) @categories = Category.find_all @tag_name = params[:tag_name] @tagged_items = Item.tags_count(:limit

I am trying to use an integer object as a flag item for displaying a link on a page called reorder that is a column in my PlanProcedures table. I''m getting an error that says The Header is NoMethodError in Manage_plan_procedures#list missing attribute: reorder Here is what my model looks like: >> PlanProcedure.column_names => ["id", "plan_id",

Hi all, I have a question about filtering on a variable. If I have the following code in my controller to select a list of users > @allusers = User.find(:all, > :conditions => [''team_id = ?'', @params["id"], > :order => ''created_at'') Is there an easy way to find out all users who

Ahoy, I made this pager, " def list @item_pages = Paginator.new self, Item.count, 10, @params[''page''] @items = Item.find :all, :conditions => "category_id = #{params[:condition]}", :limit => @item_pages.items_per_page, :offset => @item_pages.current.offset @categories = Category.find_all

Hi everyone- Model.update_all works and changes the records, but it''s not changing the updated_at field. Am I doing something wrong or is this by design?
