similar to: ''Implicit'' subselection of data in find?

Hey guys, I''m quite new in RoR, so please excuse me when I may ask weird questions. I am working on a database frontend. The layout looks mostly like a has_many bs b has_many cs c has_many ds and so on. Now I want to do some selection. Maybe I want to see all ds belonging to a specific b. I would like to do it like: http://my.host/bs/1/ds When I click around there (add new ds, show a d

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 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

Greetings, I am searching for an alternative to sun's java implementation - one that is not under gpl.. I've been reading the vmkit code for JNI.. And I notice that it is not completely filled out yet... That's fine though, I see there is filled in function like most of the non implemented functions.. Couple of questions: Is the entire llvm required for java/cli vmkit to run?

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

So, I hear that with_scope is going to be deprecated. Which is a bit of a shame, given the stuff I''ve been writing recently. I have a CMS with multiple clients. A ''client'' is essentially a company, with multiple users. Content on the site belongs to a client - content could be messages, images, schedules, etc etc. People belonging to one client should not be able

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,

I have Acts_As_Taggable Plugin working. I have a HR controller and a sales controller. I have a document in hr tagged whitepaper and a differnent document in sales tagged whitepaper when I am in hr I see the hr document tagged with whitepaper and not the sale document (what I want). but if I click on the tag whitepaper I return two documents, hr and sales. I just want to return the hr document

Hello, i want to retrieve and object from a table other than primary key ID. eg: @sites.each do |@site| @site_id = @site.id @tower = Tower.find(:all, :conditions => ["site_id =?", @site_id]) Tower Belongs to Site. so Site_id is a reference in tower object. there will be only one Tower object for Site Object. Should we give relation as has_obne in

I have the following code: class User < ActiveRecord::Base has_many :requests do def find_active(options = {}) with_scope :find => { :conditions => ["requests.active = ?", true] } do find(:all, options) end end end end Executing user.requests.find_active results in the following SQL: SELECT * FROM requests WHERE (( requests.user_id = 10 ) AND (

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 = ?'',

Hi, It seems that setting a with_scope on the parent class doesn''t do anything MyClass.with_scope(:find=>{:conditions=> ["somecol = ?", ''val'']}) do @ext_pages, @ext_rows = paginate :my_extended_class, { :per_page => 13 } end # this doesn''t generate WHERE somecol=''val'' In order for scope to work you have to call

Hi Folks, Well, it has only been more than 6 weeks and still no response to my "No localisation for rsync?" topic. :( So far, I have determined that there are at least 4 files that need translations for rsync. They are the following. main.c flist.c log.c progress.c For my initial test I only made the following modifications. main.c ------ I added the following line ... #include

is there a way to always eagerly load an associated object so that you don''t have to put :include into every finder? class Product <ActiveRecord::Base belongs_to :user #always load user when product is loaded end Product.find(1).user.login #1 query since user was loaded with the product, same as if i used :include but I don''t want to have to specify it everywhere.

Hi all ! Is this supposed to work ? class Email < ActiveRecord::Base has_many :to, :class_name => 'Recipient', :conditions => "recipients.source = 'to'" do def create!(*args) with_scope(:create => {:source => 'to'}) do super end end def build(*args) with_scope(:create => {:source => 'to'}) do

If with_scope has been called previously, how do I access the find conditions dynamically? I am asking because I am using a find_by_sql call (which clobbers the with_scope). How can I access the method scoping so that I can read it and incorporate it into my query manually? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google

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)))

Is there a way to use has_many and have it operate like such? select * from pages where site_id = #{id} or site_id is null I know there''s finder_sql, but then I''ll lose the find_in_collection goodness.

Hi Maria If you have problems just start with a small model with predictions and then plot with xyplot the same applies to xyplot Try library(gamm4) spring <- dget(file = "G:/1/example.txt") str(spring) 'data.frame': 11744 obs. of 11 variables: $ WATERBODY_ID : Factor w/ 1994 levels "GB102021072830",..: 1 1 2 2 2 3 3 3 4 4 ... $ SITE_ID
