similar to: multi level :includes for preloading objects from database

hiho. following problem. i have 3 tables in my database with each representing an object. lets say A belongs_to B belongs_to C. when i do my_a = A.find(:all) i can access B as my_a.b and C as my_a.b.c thats fine but rails querys the database each time i do that so is use my_a = A.find(:all, :include => :b) works fine for my_a.b but not for my_a.b.c so i tried my_a = A.find(:all, :include

Request for eyeballs. :-) Mongoid uses association proxy objects. It overrides #nil? => false when the association is missing. However since it uses proxy objects, !!assocation is always true. I have created a ticket with a patch that changes the association nil test to call assocation.nil? rather than use implicit coercion of the variable. See:

Hi, I am trying to preload two shared libraries while running Qemu using libvirt. To preload the shared libraries I have added an environment variable in the $domain.xml file with the following command: ``` virt-xml generic --edit --confirm --qemu-commandline

I currently have 3 tables/models: 1) Clients, 2) Charges, and 3) Court_Dates. Clients 1..n Charges 1..n Court_Dates I am trying to find all clients that have a court_date on a certain day: something along the lines of (@client.charge.court_date.date == Date.today). I have had success preloading child rows using the :include parameter, but that only works with a parent and a child, or a

I could experiment to figure this out, but maybe the work has been done so I''m going to ask. Using Ajax, if I wanted to preload several (20) small (<1K) images, behind the scenes... would I... 1 - Queue the loading of the images with Ajax one at a time, asynchronously, and ignore the completion results. Would this result in the image being in the browser''s cache even if

Hello. Using the ":include", which generates a "LEFT OUTER JOIN" SQL command, it is possible to eagerly preload second order data objects (children) for a given association. I wanted to know, if it is possible to eagerly preload and cache third order (or more) data objects, which are little-children or little-little-children. As I''ve seen. it is possible to add

Hi all, I''m building an application which uses mostly ajax to update the sections of the page. Now I''ve come to some thoughts on how to make the ajax-handling more efficient / less buggy. Currently, when the page loads up, I start some "new Ajax.Updater"-stuff to fill some sections with content from the db. I also registered watchers which also start nearly the same

Hi, I''m using an assocation extension as follows: module RequestFinder def open find(:all, :conditions => "buyer_requests.closing_date > \''#{Date.today}\''") end def closed find(:all, :conditions => "buyer_requests.closing_date <= \''#{Date.today}\''") end end with the following ActiveRecord class User

Hi, I''m fairly new to rails and I need some advice on best practice. I''m working on an application that has a calendar section (I know, not another one of those!) and I was wondering, when is it best to query your database and when is it best to preload a model. In the calendar app the user will have a month view of entries and was wondering should I preload all the entries of

I am working on a rails app to serve as the admin app for an existing java webapp. For this reason, I am constrained by the current database structure, which does not by any means conform to the ideal rails defaults. Anyway, I have the following models: class Provider... belongs_to: login class Login... has_and_belongs_to_many :demographics class Demograpics... ... Everyone has a

Hi, I wasn't sure where to write this so thought I'd just put it in the forum. The WineHQ.org website is great, just I think pre-loading the hover images for the main menu section would make the site even better as it would no longer mean the hover images would need to be loaded when the mouse is hovered over them. I found a solution here:

Hello list, I run “samba-tool rodc preload” for multiple users. If one of this users change his password, should I repeat the preload call? (I suppose yes, I need to rerun) If I need to rerun samba-tool, can user login with his old password till its expire? (I suppose yes?) Thank you. ----------------------------------------------------------------------------------------------------------

Hi, I installed a RODC on my mailserver to have a local authentication for mailusers on the machine which doesn't rely on a always-on-connetion to the office. The problem is now that the user-preload doesn't work so that the RODC is not able to authenticate the users itself: samba-tool rodc preload <user> --server <DC1> -U Administrator Password for [AD\Administrator]:

Hello RoR Groupies, I''m seeing some weird ActiveRecord-2.2.2 SQL generation when doing eager association/preloading and using joins and ordering by said join table. Here''s an example: class Photo < ActiveRecord::Base end class User < ActiveRecord::Base has_one :headshot, :class_name => "Photo" end class Mail < ActiveRecord::Base belongs_to :user end

I looked all over the place, and cannot find current answer. I want to store passwords/password hashes on my RODC, so that when my DC (Windows) fails, my users can still connect using RODC. The current state that is described (by 3 years old docs) says its WIP, so I'm not sure what to expect? Also, in documentation there is no option, to allow for preloading whole group of users, is that

Hi, I've stumbled upon this message: https://lists.samba.org/archive/samba-technical/2013-November/096322.html Which includes a patch to make user preloading in a RODC actually work. I'm running SerNet Samba packages, version 4.1.11, and this patch has not been applied. Is it blocked for some reason? Thanks in advance, -- Roberto Su?rez Soto Allenta Consulting
