Hello Rails people, I submitted a patch recently to get rid of an annoying exception raised when an AR object is created - http://dev.rubyonrails.org/ticket/10556 , had some people review it, got some pluses... What am I supposed to do now? Can anybody advise or just review the patch and take care of the issue? Thanks! -- Best regards, Yuri Leikind

Hi all, I have 2 tables and a standard one-to-many association. How do I substitute the following sql with ActiveRecord calls so that it uses just one sql statement: update geo_entities set terminal_id = 3 where id = 10 or id = 23 or id = 87; Thank you!

Hello all, Run groupbox.rb example in any of the two alpha versions and click the radiobutton in the upper right group box (those named Hilvesum 1, Hilversum 2, etc). You''ll notice that once a radiobutton is checked, it remains checked when some other radiobutton is checked. What''s the reason? Thank you. -- Best regards, Yuri Leikind

Dear all, I encounter some discrepancies when comparing the deviance of a weighted and unweigthed model with the AIC values. A general example (from 'nls'): DNase1 <- subset(DNase, Run == 1) fm1DNase1 <- nls(density ~ SSlogis(log(conc), Asym, xmid, scal), DNase1) This is the unweighted fit, in the code of 'nls' one can see that 'nls' generates a vector

Hi, new to RoR I am probably going to embarrass myself now: I have models organised in subdirectories, i.e. models |--material |--product.rb |--cross-applications |--currency.rb When I try to reference another model within the same subdirectory, everything works fine, i.e. belongs_to :product_categories, :class_name => ''Material::ProductCategory"

Hi All, My operating system is FC11...I tried to install will_paginate from github directly like this - script/plugin install git://github.com/mislav/will_paginate.git But I get an error saying [ckkashyap@KingCobra test_plugin]$ script/plugin install git://github.com/mislav/will_paginate.git Plugin not found: ["git://github.com/mislav/will_paginate.git"] I have git on my machine - I

Hi, Why are limited eager loads and conditions on the eager tables incompatible? Doing a find(:all) without :include causes a select * query to be generated, which means the id fields everwrite each other if associated tables are included using :joins. But using :include, if conditions are placed on the tables listed in :joins then Rails throws an exception when :limit is included too.

I have searched for days for an example that demonstrates what i would like to do, and this morning i thought i''d worked it out, but no....here''s what i have: Controller ========== class ProfilesController < ApplicationController def friends current_user.profile.friends end def list_friends @profile_pages, @profiles = paginate( friends, :per_page => 10) end end

Here''s the setup (working off Rails 1.1.4): Class Project belongs_to :employee Class Employee < Person has_many :projects When I try to paginate(:employees, :include => :projects) I get the error "Association named ''projects'' was not found; perhaps you misspelled it?" I can :include other models that the Person class has_many or habtm of, and if I

Consider this problem. I have an Item that has_many Features I want to find all Items with a Feature name of ''foo''. Normally you would do this.. @items = Item.find(:all, :conditions=>["features.name = ?", ''foo''], :include=>:features) This all works fine and dandy except for this problem. If you do this... <% for item in @items %>

If I ''find'' using :include, and some included associations are null, then looping through the array executing ''if obj[i].assoc'' accesses the database for a second time (as obj.assoc is nil). eg Topic, has_many posts Post has_one email and posts = Post.find(:all, :condition => ''posts.topic_id = 10'', :include =>

Hi all, I have a node structure which acts_as_tree. I am pulling the first two levels under the root node with: @root = Node.find(1, :include => [ { :children => [ :children, :parent ] }, :parent ]) How do I pull out the first three levels? What about four? @root = Node.find(1, :include => [ { :children => [ { :children => [:children, :parent] }, :parent ] }, :parent ])

Each Timesheet has an employee. An employee has a division and a location. I want to find all the timesheets with a status of 2. I then iterate over the timesheet collection and print the timesheet name, employee name, employee divison name, and employee location name. Like so: for t in Timesheet.find(:all,:conditions=>"status=2",:include=>:employee) puts timesheet.date

Notice the "AS" keyword appears many times. Oracle does not support this keyword: ActiveRecord::StatementInvalid: OCIError: ORA-00905: missing keyword: SELECT tim esheets.id AS t0_r0, timesheets.start_date AS t0_r1, timesheets.status AS t0_r2, timesheets.cost AS t0_r3, timesheets.charge AS t0_r4, timesheets.employee AS t0 _r5, employees.id AS t1_r0, employees.name AS t1_r1,

Hi all, Is it possible to do "eager loading" with polymorphic associations ? Ex : I have a Page model that acts as taggable. When I do Page.find(:all), I would like to retrieve all tags associated with a page. Thanks, Thomas. -- Posted via http://www.ruby-forum.com/.

Polymorphic associations work great until I try to do some eager loading through :include. In my example, the interface name is ":imagehaver". Here''s my little eagerly loading find line: Image.find(params[:id], :include => :imagehaver) All it gives me is an ActiveRecord::EagerLoadPolymorphicError with no further explanation. I haven''t been able to dig up anything

I have three tables, Invoices, Projects, and Managers. Each manager has many projects. Each project has many invoices. When displaying a list of the invoices, I am using: Invoice.find(:all, :include => [:project]) Since the list shows information from the project table. (For example, a table showing Invoice Date, Project Name). However, I''d also like to show the manager name.

Hi list, I get the error "Not unique table/alias" (myql 4.1) when trying eager load 2 classes that use the same base class (not STI) Example: <code> class Wedding < ActiveRecord::Base belongs_to :bride, :class_name => ''Person'', :foreign_key => ''bride_id'' belongs_to :groom, :class_name => ''Person'',
