Hello, I think this is an easy one for the average Rails developer but I''m a bit stuck. I''m creating a simple voting app: any user can create a survey, with any number of questions, and other users can then vote by creating a ballot for that survey. Here''s the modeling: class Survey < ActiveRecord::Base has_many :questions has_many :eligibilities has_many

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

From having no errors with 3.0.2 I now see lots of these errors when running my tests. undefined method `visit_CoercibleString'' for #<Arel::Visitors::MySQL: 0x000001074f4298> Anyone know what this is? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi all, I can''t figure out why my radio_buttons won''t reflect the values stored in my database. I read through some of the previous posts -- is it true that they don''t work with integers? This is the code I''m using: <% for question in @survey.questions %> <%= debug question %> <%= radio_button ( "question", :question_id,

I know R has a steep learning curve, but from where I stand the slope looks like a sheer cliff. I'm pawing through the available docs and have come across examples which come close to what I want but are proving difficult for me to modify for my use. Calculating simple group means is fairly straight forward: data(PlantGrowth) attach(PlantGrowth) stack(mean(unstack(PlantGrowth)))

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

Hi, I have the following data imported from a csv file user_id site_id name 1 1 11 februari 2 1 11 redbook 3 1 11 tips 7 3 6 sleep 8 3 6 monitoring 9 3 6 alarm Which I would like to merge/combine into user_id site_id name 1 1 11 februari,

Hi guys I'm hoping someone can help me with this. It should be easy but it seems to get stuck for no obvious reason! I am trying to set a report up in odfWeave so that we can re-run the same analysis at 3 time points as the data matures and provide an 'instant' report. To simplify the situation we have two pieces of data: site_id (numerical value 1-9) and reaction (categorical Y or

I was wondering if anybody knows an easy way to pass a method name as the scope option to a validates_uniqueness_of validation on a AR model? For example, I have nested models a bit like: class Survey has_many :areas end class Area belongs_to :survey has_many :questions, :order => ''position'' validates_uniqueness_of :position, :scope => : survey_id end class

I did not post this question to the ecology list, even though it is about an analysis using Vegan, since my question is based more on basic data manipulation in R. I think this is a fairly simple question but for the life of me I cannot find a reference for in the archives. I have an analysis using a matrix in which I needed to strip the ID variable off the input data to run the analysis. Now I

I was up late last night trying to find the cause of this, but I''m stumped. I have this relatively simple controller to load up a bio. It''s basicly id, name, desc, type (I use STI). class BioController < ApplicationController layout ''layouts/singlepanel'' def index @bio = Bio.find(:all, :conditions => [''site_id = ?'',

I''ve been trying to figure out how to do this: select_tag ''site_id'', @helpers.options_from_collection_for_select(Site.find(:all, :order=>''name''), ''id'', ''name'', @site_id) The select_tag gets output fine, but the default value isn''t set. @site_id is set in the controller (@site_id = cookies[:site_id]). In

Hello all, Thanks for the help in advance, I am having some trouble with belongs_to, and I caint seem to figure it out. I have two tables, one called ''pow_users'' and one is called ''pow_site'' pow_users has a field called site that has the site ID for primary id in the pow_site'' table. the pow_site table setup as the Site class with the following:

Having a devil of a time finding records in a self-referencing has_many table relationship. Everything is working find looking at the has_many and the belongs_to relationship. But, when I try to find all "orphans", records that are neither a parent nor a child, I can not find a query that work in ActiveRecord. This query works in MySQL: SELECT * FROM templates LEFT JOIN templates

I have a cron job that calls a shell script - the script invokes dump. I'd like to do two things: - Have the script dump the results of the job to a text file. I tried this with /path/to/dump my switches -v >> /home/me/dump.log But that just produced an empty file. - Have the dump file be date-stamped with the date it was executed. Right now, I manually edit the script to change

Hello I'm a bit confused about the "tcp time stamp validation bug" mentioned in the http://www.kb.cert.org/vuls/id/637934 advisory. FreeBSD has fixed this issue in -current (2005-04-10) and in RELENG_5 (2005-04-19). Is this also already fixed in 5.4? The CVS ID for tcp_input.c does not look like this. But I'm not sure.

After mounting a windows share via cifs I have came across the same issue as described here: http://lists.samba.org/archive/samba/2006-April/119813.html "While using vim on files mounted under CIFS, when trying to write an existing file you will randomly be warned "The file has been changed since reading it!!!". Normally, this only occurs when another user accesses and saves the

Hi ?Is there any way to reproduce the FTP behavior with Samba 3? The desired effect is not to respect timestamps from Windows files and just create them with Samba server date/time stamp when we drag/drop, copy/paste, cut/paste, old files to a disk share. We are replacing an FTP server with Samba3, so far it's doing great job, but this effect is needed (don't ask why please, app

We are running samba 2.06 on HP/UX 11.00. I have a powerpoint file on a samba share. If I access this powerpoint file on a NT 4 system, the time stamp of the powerpoint file gets changed, even when nothing of the file is changed. Does anybody know how to solve this problem, Regards,

Dear R experts, currently I'm converting a bit of trivial Splus code to R. In Splus I came across the stamp function. Does R have something similar? Thank you very much for your time. Ananke P.S.: Keep up the good work on R. It's great!
