similar to: does has_many: add a has_<associated_class>? method

In a belongs_to association, is there a way to tell if the associated object was newly created? Hopefully this will explain my question: A Firm class declares has_many<http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html#M000530>:clients and a client class declares

Hi, I have ssh configured with a non-standard port, and I use svn+ssh to access to my repository. As the svn+ssh protocol doesn''t support the colon convention to specify the port, I export the SVN_SSH variable in .bashrc, like this... SVN_SSH="ssh -p 2323" Now I can do a checkout from the command like using something like this... svn checkout

I thought I had a handle on this one but it''s causing me grief and I''m hoping somebody can set me straight. I have an object AlertTemplate which will contain a fill in the blank style hunk of web content. I then have an object, Alert, which will have a relationship to one of those AlertTemplate objects, plus some data. So, in human speak, I''d think that an Alert

Hi, I am very confused about an aspect of has_one and has_many relations, with regard to using the build method, and saving the belongs_to side. It''s a somewhat long post. so please bear with me :) First let''s consider the has_one scenario. Let''s say I have a student who must own exactly one car: class Student has_one(:car) end class Car belongs_to(:student)

I wonder if you can have more than one has_many :through association between 2 models. For example... I have a model Teacher and a model Class Now, 1 Teacher works in many Classes, right?. So I need a join model like class Work < ActiveRecord::Base belongs_to :teacher belongs_to :class end But I also would like to know if a teacher CAN teach a class before I

I am a bit confused about counter_cache here. The API docs http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html say that only the belongs_to association can take the :counter_cache option. When I try to use it on a has_many I get an "unknown key(s): counter_cache" error. Why would this be the case? belongs_to means that this model has a field with an id

Noob Question 31,265,232 if I''m searching on an object, say order, that has many "order_lines" and I want to display order lines by Quantity ( an attribute of the order_lines ) descending how could I do that without having to do a find() with :order, but something like; Order.order_lines.each do |ol| <!-- code to diplay the line --> how can I determine the field

I''ve been reading up in ActiveRecord::Associations and playing around with my app via the console and found some interesting methods via the code completion of IRB, but I have no idea how to use them and can only find one hint in the API http://api.rubyonrails.com/classes/ActiveRecord/Associations/ ClassMethods.html It mentions here in the has many associations that if you use the

I''ve created the following associations using :through: class Person < ActiveRecord::Base has_many :attendees, :dependent => :destroy has_many :events, :through => :attendees, :uniq => true end class Event < ActiveRecord::Base has_many :attendees, :dependent => :destroy has_many :people, :through => :attendees, :uniq => true

No. After bringing up one brick and before stopping the next one, you need to be sure that there are no damaged files. You shouldn't reboot a node if "gluster volume heal <volname> info" shows damaged files. What happens in this case then? I'm thinking about a situation where the servers are kept in an environment that we don't control - i.e. the cloud. If the VMs are

So, I was looking for a setup that would allow me to easily query multiple databases and not have to re-write my customer finder type queries. Here is what I came up with and it seems to be working for me in my very basic tests so I thought I''d share. Just posting it in case this helps anyone else trying to do the same thing. I''m using this with activerecord, but not rails, so

Ok. No problem. I can test it in a virtual environment. Send me the path. Oh but the way, I don't compile gluster from scratch.

I have: module MySpike extend ActiveSupport::Concern included do class_attribute :foobar, instance_writer: true end end But, I want to be able to override the class attribute writer and/or instance writer method to do something when the attribute is set via self.foobar = true before or after calling super to set the attribute. Unfortunately, I can''t find a clean way
