So, I''ve written a partial that does some stuff with a given instance of my class "entity". Entity is ActiveRecord. I''m able to retrieve all sorts of data from an @entity, until I do something like: <% for @attribute in @entity.attributes %> <div id="attribute_<%= @attribute.id %>"> <%= render(:partial =>

I''m looking for someone to confirm the following as a bug in Rails 1.0 before I post it to Trac. If I use eager loading on an association that has conditions defined, the conditions are ignored. The following example illustrates the problem. I have two tables: create_table "blogs", :force => true do |t| t.column "name", :string end create_table

Hi all, In my controller I am doing the following to populate a nested form for a has_many through association: def new @specification = Specification.new Component.find_each.each do |component| @specification.component_specifications.build(:component_id => component.id) end The idea being whenever someone creates or edits a form, it will be populated with all

I''m trying to use has_many :through, since my join model deserves being more than just an intersection table. But when I try to break the association, the break only seems "temporary": Let''s say my two tables are Users and Colors, and the join model is Favorites. user = Users.find(1) user.colors.length >> 2 c = user.colors.first >> #<Color:....>

I want to be able to do something like this (for example): class Person < ActiveRecord::Base has_many :friends def friends(living_in = :uk) # filter based on parameters here end end Is there any way I can redefine the accessor for an association whilst still being able to get the values? Basically, I''m looking for an equivilent of read_attribute() for associations. --

Assume a model Parent and another model Child. Child belongs_to Parent and Parent has_many Children. The following fails: @ p = Parent.find(:first) assert p.equal?(p.children[0].parent) @ It seems odd to me that I and my child''s parent are not the same object. In fact, this is royally screwing me up. Can anyone tell me why this is or point me at a relevant discussion, blog posting,

Hello, when using BLF with Asterisk 1.6, I notice that the Caller-ID information is not displayed on the monitoring key of my Innovaphone IP200A. If the IP-phone of my colleague rings, I should see on my partner key the number of the caller. This is information that is being send in the xml-body of the NOTIFY-message. I do not see this information in the xml-body of a NOTICE-message from

I seem to be getting some behaviour thats unexpected (for me anyway) when using find_by_contents on an ActiveRecord has_many association. The results that are returned are only the records that belong to the model returned, but the total_hits that are being returned appear to be for the whole table. e.g. class Book < AR::Base has_many :pages end class Page < AR::Base belongs_to :book

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''m pretty new to Rails, and I think my app has progressed quicker than my knowledge of Rails/Ruby has ... I have the following models: [ -- Begin -- ] class Provider < ActiveRecord::Base has_many :invoices has_one :user def self.get_invoices invoices.find(:all) end end class User < ActiveRecord::Base belongs_to :Provider belongs_to :Consumer def

Looking for some guidance/support on what feels like might not be an uncommon use-case. `User.has_many accounts` `User.has_many payment_methods` `Account.belongs_to :user` `Account.belongs_to :payment_method` `PaymentMethod.has_many :accounts` There are lots of `Accounts`. When I (a `User`) want to assign accounts to a `PaymentMethod`, I really don''t want to scope against all of them,

Hi, I am trying to overwrite the accessor of a has_many association. Basically my class looks like this: class Person has_many :emails has_one :link, :class_name => ''PersonProxy'' def emails_with_link link.emails + emails_without_link end alias_method_chain :emails, :link end Now that works fine if I only access the collection like >>

Hi Let''s say we have model Foo. Each Foo instance can have several bars. Those bars are primitive, so they shouldn''t be models. For example, Foo might be a type of convention, and the bars might be years the convention was held in. Naively, we would have a conventions_years date, and put: has_many :years inside class Convention. But then we''d get an error, since for

Which is the best way to create a thin key/value related to some model? where a field only could insert those values (keys as 0,1) and where could be showed the values (as Red, Blue) from a drop-list COLOUR_OPTIONS = {0=>"Red", 1=>"Blue"} t.string :colour --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the

So I''m one of those nasty people building a self-referential habtm-like Association using the funky new :through stuff. This is about users having friends, so here''s my user.rb: class User < ActiveRecord::Base has_many :friendships, :foreign_key => ''user_id'' has_many :friends, :through => :friendships, :source => :friend end And here''s

Hi everyone! For those of you who are not noticed the in-place edit method for collection associations are broken in the current rails release - 4.0.0, and here''s what is cooking in the rails master https://github.com/rails/rails/commit/1a40be02113287d9a003f8224e91b9f623857f4b and this https://github.com/rails/rails/pull/12227 In short: it looks like things like has_many.reject!{},

Hi All, I have been told to post discussion based topic on here instead of the GitHub Issues. I thought this ''could'' be a bug, but just need some clarification really. The issue I posted is here <https://github.com/rails/rails/issues/12597>, does anyone have any thoughts? Again: https://github.com/rails/rails/issues/12597 Thanks a lot. -- You received this message
