Hey all, I am getting this error: NoMethodError (undefined method `gsub!'' for 2012-01-22 17:00:00 -0500..2012-01-23 00:00:00 -0500:Chronic::Span): in this code: date_range = Chronic.parse(the_date, :guess => false) reports.sum_distance_by_date(date_range).each do |d| u[:m] << d end def

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

I am a little confused about the best way to work with date_select. I see that in my views it generates a simple input form that allows for the entry of year, month and date information. If I just leave it at that, great! But what if now in the controller, I want to work with the date information. I actually want to take the user input date and compute a new date some number of days in the

I have a model with a datetime field called start_date. I''d like to do a find on the model so that it returns only records with the start_date equal to the current day. Something like this: @foos = Foo.find(:all, :conditions => //?? start_date equal to today''s date ??// ] ) Thanks in advance for any help. -------------- next part

Hi, I''m trying to submit data from text boxes on a form to one variable in my controller, in the same way that datetime_select has date(1i), date(2i), etc for day, month, year, etc... I''ve named my variables event[start_date(1i)] event[start_date(2i)] and event[start_date(3i)] but this doesn''t seem to work and event[:start_date] is blank ... any pointers would be

I''m working on a fairly complex join query and could use a bit of advice from more expert users of ActiveRecord. I have an events table with quite a lot of data, with has_many relations to categories, age_groups, and event_images. In my first naive implementation, each event had a date, so to load all upcoming events efficiently, I''d do: Event.find(:all,

acts_as_ferret :fields => { :name => {:}, :desc => {}, :start_date => {} } def start_date self.start_datetime.strftime("%Y%m%d") end Now that I am strong start_date in YYYYMMDD format, I want to search for all event in between 20070506 and 20070809 What will my query look like when I am using aaf. This one doesn''t work

The below query fails: Timesheet.joins(:time_entries).select("timesheets.*, sum(time_entries.worktime) as total").group("timesheets.start_date") The models have the following relations: Timesheet < AR has_many :activities, dependent: :destroy, inverse_of: :timesheet has_many :time_entries, through: :activities accepts_nested_attributes_for :activities,

Apologies for troubling the list, but it is a test that needs to be carried out. I am resending the message that I sent earlier on behalf of Paul Miller, but with a certain word used in the variables names of the SAS code changed to a different word. With thanks for your tolerance ... Ted. [*** PLEASE NOTE: I am sending this message on behalf of Paul Miller: Paul Miller <pjmiller_57 at

lets say i have the following SQL in my database editor : When i paste it into rad rails i have to add quotes and the ''+'' symbol to the end of each line. It is very tedious. What is the best method? select timesheets.employee, sum(items.hours) as hours, sum(items.hours*timesheets.cost) as cost, sum(items.hours*timesheets.charge*decode(activities.chargetype,0,1,0)) as charge,

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

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:

Hi all, Ruby 1.8.4 Rails 1.1 OCI8 0.1.14 I think I''m hitting an issue with ActiveRecord::Base#save and the Oracle adapter.

Hello, I do not understand the correct way to approach the following problem in R. I have observations of pairs of variables, v1, o1, v2, o2, etc, observed every 30 seconds. What I would like to do is compute the correlation matrix, but not for all my data, just for, say 5 minutes or 1 hour chunks. In sql, what I would say is select id, date_trunc('hour'::text, ts) as tshour,

Hi List Apologies if this isn''t the correct place for this query (I''ve tried a search of the mail archives but not had much joy). I''m running R (2.14.0) on a Mac (OSX v 10.5.8, 2.66GHz, 4GB memory) and am having a few performance issues with reading data in from a Postres database (using RPostgreSQL).

I am just assuming this can be done, but I have not gotten close to making it happen. I have a data file with about 1 million rows with 1470 unique subjects.

Hi, I have the following problem. In a csv file I have under column A, the date, and column B, the prices. Thus, for example, the file looks something like this -> 1/31/04 2.5 2/1/04 2.6 ... 4/12/04 3.5 Basically, I use the function inputframe = read.csv( ) which reads the csv file into the inputframe. My question is, how can I make a function that has, as inputs,

I have the code for computing a weekly event: (start_date..end_date).select{|d| d.wday == wday} but I am wondering if anyone has any ideas for using this to figure out a recurring event for every other week. Is it possible to somehow specify every other within the .select method? Any other implementation ideas? --~--~---------~--~----~------------~-------~--~----~ You received this message

Could someone please tell me why this is not working? See these are events, and when the "start_date" of each event goes by into yesterday, i want it to automatically be "archived", or set the active field to "0" this is what i''ve written so far, there''s no errors when i load it but it doesn''t actually change anything in the database. if
