In my rails application, certain computers were having huge problems. There were certain pages that were exceptionally slow, even to the point of timing out. Other computers did not have a problem. I finally found that Firefox was the difference. When using Firefox on those computers it works fine. The slow pages were typically posting a form with a couple hundred fields. This behavior was

Given the case of validating the presence of an attribute and then performing other tests on said attribute, how do you go about not having to check for nil in the other tests? Example: validates_presence_of :start_date, :end_date validate :validate_start_date_before_end_date def validate_start_date_before_end_date # without this check an exception will be thrown on access to the

has_many.count does not seem to support an options hash like ActiveRecord::Base.count does. Example: >> AcademicProgram.find(:first).course_requirements.count :conditions => "courses.name LIKE ''a%''", :include => :course => 40 >> ap.ap_requirements.count :conditions => "courses.name LIKE ''a%''", :include =>

It seems that using a join model that joins with two has_many''s will fail to generate proper SQL class StudentSemesterRecord < ActiveRecord::Base belongs_to :semester has_many :discipline_records, :through => :semester end class Semester < ActiveRecord::Base has_many :student_semester_records has_many :discipline_records end class DisciplineRecord <

My completely empty model (no validation callbacks etc etc) takes an average of 0.05 seconds to create, at least according to Benchmark.realtime{200.times{Message.create(:from => "me@here.com", :message_type => ''email'', :subject => "hello", :body => "goodbye", :sent_at => Time.now)}}/200 That''s a little slower than

Hello all! I have two views (list_1 and list_2) that show a list of users in two different ways. In the views for these actions there is a link to edit a specific user properties (edit_user). That works fine, except that when I change the user I want to go back to the view that originated the request and not to the default list (list_1). Can anyone help me? Best regards, Hugo -- Posted via

How do you run an ad-hoc query that does not belong in any model? I thought it was something like ActiveRecord::connection.find("my query..."), but I can''t seem to find the documentation on it. I know I''ve seen it somewhere before, though. thanks, Jeff -- Posted via http://www.ruby-forum.com/.

I''m having problems with class variables.. I have a class: class Content::ApplicantsController < ApplicationController layout "mylayout" @@tab = "mystring" [... the rest is standard scaffold-created stuff ...] and a layout (mylayout.rhtml): [...] <title><%= @@tab.capitalize %></title> [...] And I keep getting this error: uninitialized

Let''s say you want to validate that an attribute contains only 2-10 lowercase characters, e.g. with validates_format_of. The appropriate regex is obviously /^[a-z]{2,10}$/, right? Wrong! Try it with "abc\nANYTHING YOU LIKE" - this is perfectly valid. On the second look the reason is clear: ^ matches the start of a line, $ matches the end of a line. So as long as one line in

Hi, This code loops through my results and saves them : @results.each{|r| r.save} There are potentially thousands of results. This takes ages to complete. Is there a quicker way to do this? Any help is greately appreciated Thanks Chris -- Posted via http://www.ruby-forum.com/.

I''d like to include the user name along with/instead of the session id in my log files. Is there a place to customize the log format, or do I just need to through the logger object and manually write it in a before_filter on my ApplicationController?

I''m having some difficulty deciding where to put logic that crosses models. For example, given models people, departments, work schedules, and weeks. Where would the following best fit: who is scheduled to work in a given department in a given week? how many hours is a given person scheduled in a given week? how many hours is a given person scheduled in a department in given week? how

Hello happy Railers, I used to develop with a local out-of-the-box Apache and load times were pretty slow (like a few seconds each page). "Well, it''s the price to pay for no compile / cache / etc..." I thought. Nonsense. Yesterday I installed SCGI, and now I''ve got the best of both worlds: rails development env uses my very latest modifications, while SCGI ensures I

Hi! I recently started with RoR and this may be a newbie question. I have a company table, employee table and transactions table. 1 company has many employees. Each employee performs many transactions. Employees from different companies LOGIN to the system to record their transactions. Employees can search on all transactions associated to their companies (indirect relationship via employee),

Hi all I tried and tried and tried, but I still fail in creating a form with proper validation and stuff for foreign keys... So I''d really like to get some help here.

This is apache/fcgi/rails/firefox. When using a rails app we have been experiencing sudden blank pages in the browser.
