Hi there, Just a simple question I guess, but I am unable to find an anwser... How to delete a hmabtm relation? Any help will be appreciated :) Thanks, Fabrice. -- Posted via http://www.ruby-forum.com/.

hi, after we switch our servers from centos-3 to centos-4 (aka. rhel-4) one of our server always crash once a week without any oops. this happneds with both the normal kernel-2.6.9-11.EL and kernel-2.6.9-11.106.unsupported. after we change the motherboard, the raid contorller and the cables too we still got it. finally we start netdump and last but not least yesterday we got a crash log and a

I want to do in-place edits on a list of data, but I''m having trouble getting the ID passed through to the controller. I use this in my view to create the field: <% for frame in @frames %> ... <%= in_place_editor_field :frame, :price %> <% end %> and this produces the following in my output: <span class="in_place_editor_field"

In my application model I have three classes: Accounts, Projects, and Items class Accounts < ActiveRecord::Base has_many :items, :through => :projects, :source => :items has_many :late_items, :class_name => ''Item'', :through => :projects, :conditions => [''due_on < ?'', Time.now], :source => :items end class Projects <

I''m about to implement this, and I''m thinking of storing the user''s id and their hashed password in the cookie after a successful authentication. can any see an obvious security issue with this? I know the method is vulnerable to cookie theft but am i missing anything? thanks alan

Hi all: I have an application that runs great on my macbook pro, however, when I move the app to the production linux box, all routes fail except for the one I set up as the default: map.connect '':controller/:action/:id'', :controller => "Employee", :action => "status" I made sure the shebang line in dispatch.* was set to be OS independent

Hi, I am trying to hide a "intro" text shown to user the first time after he has made a search, in the website with RJS/Prototype "hide". I get the following error: RJS Error: Type Error: element has no properties. The text I would like to hide is in a div called "intro" and in my RJS I tried: - page.hide[:intro] as well as - page.hide ''intro''

Let''s say I have two different geographic sites. They are pretty much identical ie. each site has a machine called web1 which is a web server, etc. Except there are couple site-specific settings ie. outgoing DNS servers are different, SSL certs are different etc. On the puppetmaster I can put in a file called e.g. /etc/sideid which would uniquely identify a site ie. siteX or siteY.

This has got to be something obvious that I am missing... I have a remote form that has one value that is passed back to the server from a text field. The form has a set of parameters passed to the :url key called search_params. When the field is empty and the form is submitted, I get :my_val => "" as expected when I examine the log. All is well with the world. I need call that

Hi, I need to be able to add one month or in some cases on eyear to a Date. Does anyone know of any easy ways of doing this? thanks scott -- Posted via http://www.ruby-forum.com/.

I am trying to take the input from a field in wich the user enters a date, and formatting it to my time format if params[:gotcha] != '''' gotc = params[:date].to_a gotc.strftime("%m/%d/%y") end Yet I get this error: NoMethodError in AddController#add undefined method `strftime? for ["00000"] What''s wrong.

I am using a random intercept model with SITEID as random and NAUSEA as outcome. Thanks. Anamika I tried using a dataset without missing values and changed my model statement accordingly but still get the same error. Follwoing in an excerpt. > anal.data <- read.table("nausea.txt", header=T, sep="\t") > list(names(anal.data)) [[1]] [1] "SITEID"

I'm estimating two models for data with n = 179 with four clusters (21, 70, 36, and 52) named siteid. I'm estimating a logistic regression model with random intercept and another version with random intercept and random slope for one of the independent variables. fit.1 <- lmer(glaucoma~(1|siteid)+x1 +x2,family=binomial,data=set1,method="ML",

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)))

I''m trying to use one form to upload a file to the file system and insert a title and description field into the database. I have no problem uploading files to the file system using the code from http://wiki.rubyonrails.com/rails/pages/HowtoUploadFiles There are more fields on the form than need to be inserted into the database, name and file. I need to pull out these extra fields

I think I must be missing something obvious...

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,
