I had a statement that was generating a warning about parenthesise argument for future version. The interesting thing was it would crash the page with an input/output error on my production linux server, but worked fine in webbrick/windows. I finally tracked it down to it crashed when trying to print the warning to the console. If I kept the terminal open that I started the server on it would

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

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 <

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? Thanks. -- Jack Christensen jackc@hylesanderson.edu

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

I''m trying to create a separate class to do validation so that about 10 models can use the same date validation. I have tried to use the example from the agile book but it''s not working. Here''s what I have: app/models/date_callbacks.rb class DateCallbacks def before_validation(model) if model.start_date > Date.today model.errors.add(:start_date, "must

Hi All, I''m stuck yet again. I have an action on a controller that produces a Ziya graph, which I call using the gen_chart() helper. However, I can''t seem to pass more than one parameter through to the action. <%= gen_chart( "overview_graph", url_for( :controller => ''graph'', :action => ''graph'', :graph_id =>

Hello all, I''m trying to create a HABTM checkbox action that adds/updates ''users'' to a ''project''.

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

I have created a pagination with my own conditions : @timesheets_pages = Paginator.new self, count, 30, @params[''page''] @timesheets = Timesheet.find :all,:include =>{:employee=>[:location,:division]}, :conditions => ["employees.location=? and employees.division=? and start_date>? and end_date < ?

Can you see an obvious reason why this date_select code is failing? The parameters from the form - *Parameters*: {"commit"=>"Save All Changes", "campaign_id"=>"1", "campaign"=>{"name"=>"fdsfas", "end_date(3i)"=>"26", "start_date(1i)"=>"2006",

Hello It seems that datetime_select, is creating an instance of the Time class. Why would that be? I found this while building a site where people can create vigils (prayer vigils, peace vigils, etc). When I added a validation method that compared start_date to created_at, it generated the error: ArgumentError (comparison of Time with DateTime failed): I was able to put a breakpoint in the

Folks, i thought it should be straightforward but after a few hours poking around, I decided it's best to post my question on this list. I have a data frame consisting of a (large) number of date columns, which are read in from a csv file as character string. I want to convert them to Date type. Following is an example, where the first column is of integer type, while the rest are type

Dear all; I am searching for a way to extract wind direction and speed from a wind rose plot. I have a graph and I want to make a dataframe of 5 years with hourly intervals. > start_date <- as.POSIXct("2019-01-01 00:00:00") > end_date <- as.POSIXct("2023-12-31 23:00:00") > time_sequence <- seq(from = start_date, to = end_date, by = "hour") > df

Hi! I have a table with visits with a visited_at: attribute which is a datetime field. They seem to be stored as UTC. Now I want to count all visits each day and return something like: { 2013-01-01: 8, 2013-01-02: 4, 2013-01-07: 9, ... } So, I did it like this which kind of works...: def self.total_grouped_by_day(start_date, end_date) visits = where(visited_at:

I have searched the forums but I am having trouble trying accomplish two specific plots.

Hi there, I’m trying to merge JSON results from an API call in with ActiveRecord results for a blended display in a view. I’d like to be able to merge the two result sets based on ''created_at'' which is is common in both the ActiveRecord results and the JSON results from the API. Created_at is the only common element between the two data sets. Here’s what I have in my controller

A wind rose plot omits time information. Your request is simply not possible.

Hi, I am almost embarrased to ask this and I am sure it has been answered previously but the search feature is down on ruby-forum so I am not finding the answer. I have several controllers (leads, orders, activities, etc...). I have a ton of repeated html in each of the views for these controllers. For example, my list view has the same table/tr/td and for..in type of code and it just
