Hi. I''m attempting to return a result set which filters Pages by their active state and their start/end date. Whilst the code I have at the moment is doing this without problem, some of the Page items may not have an end date set and I can''t see a way of conditionally doing the query so these are not excluded. Perhaps showing some code will help explain better;

Hi to everyone, I have the following models: class Attachment < ActiveRecord::Base has_attachment :content_type => [:image, ''application/pdf''], :max_size => 3.megabytes, :path_prefix => ''../private/attachments'', :storage => :file_system, :processor => :rmagick,

Hi! I have a has_one association which is used for extending an entity, like: class User < ActiveRecord::Base has_one :user_ex #name, email end class UserEx < ... #country, city, street... end The UserEx entity is optional (there are users without extended info). My problem is: if u is a User object which has no user_ex extension, activerecord always tries to fetch the UserEx

Hi... Isn''t there a proper way or hack/workaround for the following? * For the example with unfortunate disabilities.. look below,,, Usage of has_* (associationmethods) do {def with_deleted AccociatedModel#with_scope} {Paranoid''s#find_with_deleted}...

Hello, I''ve come across an issue that I''m sure is a bug when using after_create with a has_one association, but I''m not 100% certain if I''m missing something. This is pretty much exactly the code I''m using. Two simple classes (Account and Contact) and I create the contact after I create an account (via after_create). I''m not passing in a

Hi, I''m struggling with something that must be very common pattern, and want to do it the correct rails/ruby way but am a bit dense ! I have users - an admin user, registered users and a guest user (using ModelSecurity) For many of linked associations I want the admin to be able to list or edit all instances, the registered user only their own one and guest none at all. So somehow I

Hi, Have an issue with the rails auto complete, it works fine but I don''t know how to find the id element search in the textfield. Here is what I''ve done: <%= text_field_with_auto_complete :user, :ville_name, { :size => 15 }, { :url => formatted_villes_path(:js), :method => :get, :param_name => ''search'' } %> Model: class User <

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 have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

I''m having a difficult time wrapping my head around a set of models and their associations and seeing how they map into Rails. I''ll try to lay out my problem using the has_many and belongs_to structures. I have a RuleSpace, a Rule, and a Subject. A RuleSpace has_many Rules A RulesSpace has_many Subjects through Rules A Rule belongs_to (many) RuleSpaces A Rule has_many

Not sure if this is expected or not. Only happened with a has_one :through I had setup. (Workaround is just to remove it and go through the association manually vs has_one ..., through: .) Not a big deal if no one has time to look at it, as it''s not a big enough deal to look into a fix on our side. In Rails (3.2.9) console if I do: MyModel.reflections.each {|name,reflection|

I''m new to ruby and rails and as a result am a bit lost on implementing a one to many relationship. In my DB I have 2 tables contents and locations, contents contains the foreign key location_id.
