similar to: multitable form

I''ve got a fairly simple system with a table for my Users that includes a CountryId field which looks up to the CountryId field of my Country table. What I would like to happen is for my Rails application, which contains models for both User and Country, to be able to draw the dropdown list of available countries on the edit page, like it does in all the tutorials. My model classes look

Hi I am using seed_fu to seed initial data to tables (http://github.com/mbleigh/seed-fu) . And in db/fixtures/state.rb I have values like (I am filling only two data for simplicity) State.seed_many(:name, :abbr,:fips,:country_id, [ { :name => "Alberta", :abbr => ''AB'',:fips => ''01'', :country_id => 2 }, { :name =>

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

I have an address model with country_id and province_id fields There is also a full_address method that returns an address that is in a format that the google maps api will be able to return a long-lat coords. Within the full_address method there is a call to obtain the province/state and country name. --------- def full_address ... full_address = [city, self.province.name,

I am very new to ROR. (Ruby 1.8.7, rails 2.1.1, rack 0.8.7, mysql 5.1.41) I has my_app/lib/migration_helpers.rb file: module MigrationHelpers def self.foreign_key(from_table, from_column, to_table) constraint_name = "fk_#{from_table}_#{to_table}" execute %{alter table #{from_table} add constraint #{constraint_name} foreign key (#{from_column})

I was hoping someone would be able to help me with creating a method. I have two tables. What I am trying to do is create a list of all the id''s from table2 that aren''t currently referenced by Table1''s address_id column. That way, when I create a new customer I can have a drop down list in the view of all the addresses that are not currently being used. ##### Database

Hi, My saves are failing me and I can''t figure out why. I am trying to save an address id to a user object just after I create the address. This isn''t the exact code, but it shows what I am trying to do. class AddressesController < ApplicationController def create @address = Address.new(params[:address]) saved_address = @address.save @user =

Hi all I tried and tried and tried, but I still fail in creating a form with proper validation and stuff for foreign keys... So I''d really like to get some help here. I''m creating a booking site for DJ''s, and for every booking one can choose one of different countries: class Booking < ActiveRecord::Base validates_presence_of :country_id

I am very confused about where to put the belongs_to and the has_one (and other relationship identifiers). I have read the RDoc and the agile book many times about this and I think i still see it backwards. Let me outline my app so you have an understanding... I have 2 tables: Schools { id, school_name, address_id } and Addresses { street1, street2, city, state, zip, country } *** this

I have two models bank and country. User should only associate a Bank with a country id present in the country table and I put validates presence of country to enforce it but i get error mysql2::Error: Unknown column ''countries.bank_id'' in ''where clause'': SELECT `countries`.* FROM `countries` WHERE `countries`.`bank_id` = 17 LIMIT 1 when updating the bank

I am sure some of you can give me an insight into this. This is more towards the database design for the scenario below: Say for example, I have a person table and this person can have different address types. One could be Home and the other could be say Office. Should be model this Table people id fname lname Table addresses id person_id addr1 addr2 .... or Table people id fname lname

Hi,R 2.15.2 plm() function on Windows 7 when i perform a plm regression, i can't manage to obtain the intercept, but I need it.it gives me just the beta coefficient. my formula: fixed <- plm(deltaS ~ L1.deltaS + L2.deltaS, data=Mody_R, index=c("country_id", "date"), model="within") my output: Coefficients : Estimate Std.

I created a form with two collection_select, country and state and would like to bring up to date the state list when to select a new country. How I can make this in Rails? Thanks Eleudson Brazil <p><label for="person_country_id">Country</label><br/> <%= collection_select(:person, :country_id, @countries, :id, :name) %></p> <p><label

Hi all I guess this is quite a newbie question, but I''m just stuck here and don''t know why. <%= form.collection_select :origin_country, Country.find(:all), :id, :name %> gives me a select list with name="member[origin_country]". When submitting the form the following error is shown: Country expected, got String When I try <%= form.collection_select

I am very new to Rails. After skimming through the documentation over the last several days, I''m struggling with the appropriate use of belongs_to. My main question is whether a model can have several belongs_to declarations. I have not seen any examples online show that usage. If it can, then I would like to know if it''s poor form or what the best practices are around

Matteo, I fully agree with David: please read the posting guide. Anyway, the error message says it all: "the estimated variance of the individual effect is negative". See e.g. the "basic panel" chapter (10 or 11) in Wooldridge's "Econometric Analysis of XS and Panel Data" to understand why this may happen. Stata's behaviour is (as far as I remember) to

Folks, Am new to RoR and am building an example to get myself familiar. I am running into a simple issue while creating a user registration page. I have a User and Address models defined as below (partial/relevant code included below). User has_one address and Address belongs_to user. I have a foreign key defined in address table that refers to user(id) In a form I take in username, password,

Given two models: User :name :email :address_id # foreign key Address :line_1 :line_2 :city etc. I want to have a form allowing a user to register, in which she''d enter an address as well, but how do I go about combining both objects into the one form? I''m new to this and following along with the Agile Rails book from the Pragmatic Programmers, but it
