When using has_one or has_many associations, how do I prevent a call to the parent''s save() method from calling the child''s save() method? I seem to be stuck in an infinite loop due to the way I have my associations setup :-( thanks, Tim

I have a 2 entities which have many to many relation say teacher and slot. Each teacher has many classes he/she takes up and each class is a slot. I want to perform search on teacher by sunspot solr for all the teacher who takes classes for different days in specific time.

hi all, i''m new to this group and currently using Rails 3.0.3 and meta_where 0.9.10. i''m considering how to make a full-text searching feature to my project, and my models, for example, should be defined like below: class Group < ActiveRecord::Base has_and_belongs_to_many :users # :title (string) end class Comment < ActiveRecord::Base has_and_belongs_to_many :users

Hello folks, I spend some time today mucking about trying to figure out how to make our documentation search a better experience. The short answer is, search kind of works now. Long answer: mkdocs creates a client side file which is used for search. RTD overrides this by referring people to Elasticsearch. However, that doesn't clear out stale entries and we're plagued with a whole lot of

Hi all, I''m using rails version 1.2.3. I have the following association in my View class belongs_to :viewer, :class_name => ''User'', :foreign_key => :viewer_id And of course i have a User model class defined to. The problem was that when i tried to use this association it would only work once. At the second try, i would get the following strange error:

So I want to SELECT from multiple tables, so as to be able to do "SELECT FROM foo, bar WHERE foo.id=bar.id AND bar.baz=23". How do I do it with AR#find? Also, I need this for associations. has_many et. al. have :finder_sql, which is nice, but feels like a Pyrrhic: it''s basically doing the association in pure SQL, defeating the purpose of AR. -- -Alder

I have a plugin which does something like this for different associations: belongs_to_klass.send(:belongs_to, belongs_to_name) This works fine for the first page request in mongrel/webrick, but the associations are lost on/by the next page request. Any ideas? Thanks :o) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this

I just returned from a week's vacation and brought my CentOS 5.0 system back up, updated it, and somehow it has lost all the .doc file associations. These used to be associated with the OpenOffice writer, but that's now gone. ACtually, all the "open with" associations are gone (rtf's now think they should be opened by the text editor!). I'm not sure exactly what the

Hello, I found an interesting ER diagram on the "Module: ActiveRecord::Associations::ClassMethods" page of the Rails Framework Documentation : http://ar.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html At the beginning we can read ? Associations are a set of macro-like class methods for tying objects together through foreign keys. They express relationships like

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

My question is whether the rails helper methods for handling associations can be nested (see examples below). I suspect not as currently I''m getting "unknown method" if I try and use two associations in one call. The essence of the code is class User << ActiveRecord::Base has_many :items class Items << ActiveRecord::Base has_many :reservations belongs_to

Hi, I''m looking into write scaffold generators that will, amoung other things, scaffold active record associations (eg. generate select boxes for belongs_to where you can choose a parent object) for quicker prototyping. But... My question is: Is there anyway of finding out what associations exist from examining the lodel classes themselves or indeed any other way of finding out this

Hi, After updating from CentOS 4.92 to 5 through manual hacks and 'yum update' (see http://lists.centos.org/pipermail/centos/2007-April/079023.html), I've lost all gnome file associations. Now every file is identified as application/octet-stream or text/plain or x-directory/normal (for directories). I've checked everything with 'rpm -Va' but couldn't find problem

I have create a web service to expose data from my application and am wondering why the associations are not showing up as values in my WSDL or SOAP response. In active record I have enabled eager loading so that the object set as the return type for the service call has all the associated data prior to the response. However, the associations are not showing up. Anyone have any ideas? I can

Is there an easy way to programatically work out the associations on a model? If not, is there a positive reason it was omitted, or is it just something that hasn''t been implemented yet? Thanks Gareth
