Hello, Let''s say I have a model for a "house". Each house has_a "city", which in turn has_a "state" which in turn has_a "country". The objective is to retrieve all houses in a given state, say "Massachusetts". Being new to Ruby on Rails what I like is that things that should be simple usually are simple, and since we have easy access to

My models: class Country < ActiveRecord::Base has_many :regions has_many :assets, :dependent => :destroy accepts_nested_attributes_for :assets end class Region < ActiveRecord::Base belongs_to :country has_many :appartments has_many :assets, :dependent => :destroy accepts_nested_attributes_for :assets end class Asset < ActiveRecord::Base belongs_to :region

Given the models Country, State, City and Person as follows. class Country < ActiveRecord::Base has_many :states end class State < ActiveRecord::Base belongs_to :country has_many :cities end class City < ActiveRecord::Base belongs_to :state has_many :people end class Person < ActiveRecord::Base belongs_to :city end Is there any way that doesn''t allow to delete

HI All, I am having Model "Customer" using STI for sender and receiver, and i am unable to save the both sender and receiver by nested attribute. Below are my model and active admin resource codes, correct me if i am wrong nested attribute on concept. CUSTOMER MODEL: class Customer < ActiveRecord::Base belongs_to :sender, :class_name => "Customer" has_many

Given a set of data: > names(data) [1] "city" "house" "visit" "value" I am looking for a way to compute the variance components of the nested model (ie, visit 1 at house 2 at city 3 isn't related to visit 1 and house 2 at city 4), but different houses in the same city may be related, and different visits to the same house are probably

Hi friends! I''m relatively new with Rails and I''m struggling for a long time with this problem (it should have a pattern solution but until now I didn''t find it): I have the following models: Institution, City, State and Country. class Country < ActiveRecord::Base has_many :states has_many :cities, :through => :states end # == Schema Information # Table

With ref to my previous post: http://www.ruby-forum.com/topic/180356 I am now able to access items from topics controller. However, now I need to add sub-item e.g.: An item itself could have many sub-items. So my items model is like: class Item < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:topic_id] validates_presence_of :topic_id, :title, :owner, :position

Hello everyone, I am trying to use a RESTful controller for user inside a namespace using AS and one outside for registration and so on. When i try to visit the namespaced url I get Unknown action. Once i replace active_scaffold :users with a def index; end i can the URL. My routes look like: map.register "register", :controller => "users", :action => "create"

Hi all, I''m looking for some insight on why my text_field_with_auto_complete might not work in Internet Explorer. I''m using it in a fairly simple way, without much customization. I''ve broken it down and made a test page at http://realty.colemanation.org/houses/test which shows the behavior I''m having problems with. For me on Windows XP this page works

Hi, all In my rails app I have a controller called Dashboard::MenusController with a namespace dashboard. I have a model Company too, where its has_many :menus So, I have the code above in my route.rb map.namespace (:dashboard) do |dashboard| dashboard.resources :companies, :has_many => :menus end With this route I can create a new menu by: dashboard/companies/1/

I have: class Country < ActiveRecord::Base has_many :states has_many :cities, :through => :states has_many :places, :through => :cities end What is the query RoR is using when I type: @places = @country.places Is it only one query with joins? -- Posted via http://www.ruby-forum.com/.

The shift to the :has_many and :has_one options when defining nested resource routes has me perplexed. The block format allows me to define custom REST actions like publish in the example below: map.resources :users do |user| user.resources :articles, :member => { :publish => :put } end It also allows for multiple levels of nesting if necessary. What I''d really like to

Hi, I can''t seem to find a solution to the folowing problem. I have 3 resources that are all bound to eachother like this: class Item < ActiveRecord::Base belongs_to :item_category // has a date and amount attr end class ItemCategory < ActiveRecord::Base has_many :items has_many :item_tops // groups the items in categories end class ItemTop < ActiveRecord::Base

I have a couple of resources, one nested in the other, such that my resource spec in routes.rb is: map.resources :parents, :has_many => :children This will generate a route for a new child that assumes that the parent has already been saved, something like: /parents/:parent_id/children/new But what if I want a route that handles the case where the parent resource is also new, and thus

Hi there, i have a model house and a model owner A house can have many owners. Now i want to find all owners of a specific street and i want to list them So i do: houses = House.find(:all, :conditions => ''street LIKE "%foo%"'') So now i got an array of all houses in that street @owners = houses[0].owner i''ve got all the owners of the first house. but

belongs_to :through Why is that not possible? We should have: Street belongs_to :city belongs_to :country, :through => :city -- Posted via http://www.ruby-forum.com/.

Hi! I''ve got a quick question in routing. Is there any difference between map.resources :stuff, :has_many => :inner_stuff AND map.resources :stuff do |stuff| stuff.resources :inner_stuff end ? Both calls seem to do the same thing - they just register the :inner_stuff as a resource inside :stuff resource (in terms of routes). Do they? Thanks -- Posted via

Hi guys, I was thinking aboiut this for a while: If I have nested resource routes, for example /building/1/floor/2/ room/ 3 (building has_many floors and so on), I have to call the room_path method like this: room_path @room.floor.building, @room.floor, @room Isn´t there a better way to handle nested routes with foreign keys, or can I have this method overwritten somewhere? Greets Jonas

Howdy, I''m a Rails beginner working on my first significant project with RoR. I''m trying to figure out how to validate a foreign key (you know, make sure the row actually exists.) However, validates_associated doesn''t seem to be what I want to use, nor does it work... -- BEGIN -- class City < ActiveRecord::Base has_many :schools belongs_to :state

I thought I had this fixed, but apparently not. It works okay from the console, but not from the view. I have the following: # partial schema create_table "users", :force => true do |t| t.string "login", :null => false t.string "first_name" t.string "last_name" t.string "email", :null => false
