similar to: accessing created_on causes type error

Hi, I'd like to get away from SAS, but I don't really know R well enough at this point to know if it would be good for this project. I tried to describe the essence of the project below without getting bogged down in details. It starts when I receive a data flat file. There's lots of columns, but the relevant ones are: custid (customer ID number) saledt (date of sale)

Hello all, Rails 1.0.0 created_on is being set to 2000/01/01 00:00:00 Any ideas on this ? Thanks! Schema is create table user_login_history ( id int identity(1,1) not null, user_id int not null, created_on datetime default(getdate()) not null, created_at datetime default(getdate()) not null, updated_on datetime default(getdate()) not null, constraint pk_user_login_history primary key clustered

Hello all, I''m creating a many-many join table between ''homes'' and ''users''. Can it contain created_on? will AR update created_on, updated_on on this table? CREATE homes_users ( home_id int not null, user_id int not null, created_on datetime null, updated_on datetime null ) Thanks for your advice! -- ------------------------------ Apple MacBook.

All, My initial list is rather busy. I would like to shorten the created_on and updated_on fields to just display the date, not the time. Best wold be a simple 12/28/05 type of presentation. I''ve found the format helpers in rdoc. (ie. distance_of_time_in_words_to_now ), but none seem to be what I''m looking for. How do I control the date format of a timestamp field? Thanks

Hi you all, I have a model simulating an ActiveRecord model, according to the tips stated in [1]. It is simulated because even though I am gonna save the attributes in a file, not in a DB, I still want the validations made by ActiveRecord::Base (see code below). Well, the thing is that I also want the behaviour of the created_on and updated_on columns, that get modified automatically before

We are using Rails for a project that must integrate with a legacy database. Is there a way to get Rails to automatically set the timestamp for a column named something other created_on or updated_on ? Also, how does one manipulate the size of the database connection pool?

Hi! Definite newbie here - I''m working through this like-hate relationship with Ruby and Rails right now... sometimes things work really well (like blobs seem to rock) but other times, I dunno! :-) Anyway, I''d like put in create and update user timestamps on all my primary domain tables and allow them to be updated automatically by ActiveRecord. Coming from Hibernate, I just

I am a newbie and I am running into a problem which I cant understand. I have a table called ''privileges'' which has the following fields CREATE TABLE `sdqualplanner`.`privileges` ( `id` int(10) unsigned NOT NULL auto_increment, `name` varchar(20) NOT NULL default '''', `description` varchar(100) NOT NULL default '''', `section_id`

I believe you need to spend time with an R tutorial or two: a data frame (presumably the "table" data structure you describe) can *not* contain "blanks" -- all columns must be the same length, which means NA's are filled in as needed. Also, 8e^5 * 7e^4 = 5.6e^10, which almost certainly will not fit into any local version of R (maybe it would in some server version --

Hi- Ruby 1.8.2 Rails 1.1 so I''m trying to build my first rails app and I''m trying to understand how the helper methods work. For instance .new & .save . For instance, I''ve created a table of Objects, and generated a scaffold. I see that in the controller, there are calls to Object.new and Object.save. I''m assuming that these are methods inherited

Hi everybody I am totally new to rails and I am trying to start a tiny project to get familiar with rails. But I already got my first problem and I would be happy if somebody could point me in the best and cleanest direction. I am trying to develop a small gallery app. Since I would like to add more features in future I am trying to design a clean OO architecture of my models: The base object

I was trying to do SUM based mySQL query simliar to the following: SELECT SUM(updated_on - created_on) AS total from signups If I were to run this command in the mySQL console I would get a result. However, if I were to run it using the following command in Rails: Signup.find_by_sql("SELECT SUM(updated_on - created_on) AS total from signups") The query that is written to the log is:

Hi All I have a datafram which looks like this : CustomerID DietType 1 a 1 c 1 b 2 f 2 a 3 j 4 c 4 c 4 f And I would like to reshape this so I can

I have a model which has the created_on and updated_on fields. I would like to find the newest instances of my model from the database(for instance, last 10), but as I''m only 6 weeks into my Rails development, I''m not entirely sure how to do it. Any suggestions? Thanks, David

Hi all, Im trying to get my head around rails and to help along Im working through "four days on rails" as this seems to give a good real world example with multiple tables and relationships (the main thing I cant work out!) Ive got stuck. Some help would be really good here. The controller has this code: def list @category_pages, @categories = paginate(:category, :per_page =>

Hi All, I''ve tried to do my searches, but can''t find reference to this anywhere - My question is about ActiveRecord inserts and IDs. I have a join table that both the models of the source tables join with "has_and_belongs_to_many". It seems like ActiveRecord is setting the "id" field for the join table- This should be an auto_increment and

Hi I have the models 1.ServiceDeskTicket with fields id --- number --- service_desk_status_id -- created_on -- updated_on etc 2.ServiceDeskActivity with fields id -- service_desk_ticket_id -- description -- created_on -- updated_on 3.ServiceDeskAttachment id -- service_desk_ticket_id -- attachment -- created_on -- updated_on Relations as ServiceDeskticket has_many

Hi all, I've got some functioning code that I've literally taken hours to write. My 'R' coding is getting better...it used to take days :) I know I've done a poor job of optimizing the code. In addition, I'm missing an important step and don't know where to put it. So, three questions: 1) I'd like the resulting output to be sorted on distance (ascending) and

We've been trying unsuccessfully to connect our Meridian Option 81C to a TE110P via PRI. We've followed the directions in asterisk-meridian-a1.pdf (link on http://www.voip-info.org/wiki/view/Asterisk+legacy+integration), but it doesn't seem to work on our 81C (even though many, many users report it works very well on Option 11's). Has anyone had any success in getting the above
