Hi, I am having issues with a one to many relationship(it never works :-)). Jokes aside, I am getting an error: Mysql::Error: #23000Cannot add or update a child row: a foreign key constraint fails: INSERT INTO adverts (`image_url`, `price`, `title`, `website_url`, `description`, `user_id`) VALUES(''bb'', 22.0, ''aa'',

Dear All, Fairly new to rails and Heroku, so could be doing something wacky - do let me know if you think my code practice is off, even if unrelated to this error, I''d like to learn! I''m using Rails 3.0.0, ruby 1.8.7, and ''sqlite3-ruby'', ''1.2.5'', :require => ''sqlite3''. I''ve got an application that goes off and

Hi folks, I''m in the process of converting a Test::Unit functional test to RSpec, but I''ve run into a slight problem. I tried looking through the documentation but I still don''t know what I missed. Thanks in advance, Blake describe VenuesController, "on update" do before(:each) do @venue = mock("venue")

I''ve tried tackling this many ways on my own and can''t find a good solution: Breaking it down to something simplier... Venue has one address Person has one address Address belongs to state Assuming I don''t want to do tables for venue_addresses and person_addresses. What is the best way to model this using rails... big thing here is i want to be able to reuse a

class Event < ActiveRecord::Base belongs_to :venue belongs_to :category end class Venue < ActiveRecord::Base belongs_to :city end class City < ActiveRecord::Base belongs_to :state end I want to retrieve all event records belonging to a state. Coming from hibernate background I tried something like this: def self.list_for_a_state(state_id) find_by_sql(["select e.*

I have in my view the following: <% 0.upto(@num_performances) do |idx| -%> <%= text_field ''performance'', ''city'', :index => idx, %> <%= text_field ''performance'', ''venue'', :index => idx, %> <% end -%> and in my controller I have: @performance = [Performance.new("city" =>

Hi, In my user_controller.rb, I have the following method, which is supposed to send the user to their profile, dependng on what "role" they are (the roles correspond to the other controllers: venue, band, fan): def login if request.post? if session[:user_id] = User.authenticate(params[:user][:login], params[:user][:password]) flash[:message] =

Before I waste more time trying to figure that out, I was wondering if it''s even possible? The Rails Way says that observe_field by default will trigger changes in text fields and text areas, and on clicks for radio buttons and check boxes. So perhaps I''m using the wrong tool here? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you

I''m sorry to be asking trivial questions, but I''m new to RoR and am hooked :), so I''m very impatient to get things up and running. given two related tables, "pcs" and "venues" (venues have many PC''s and each PC belongs to one venue only) I can use a select() to present venue names in the "new PC" form along with other PC details to

I have skimmed through many web pages, how to''s and editorials, my final conclusion is that the programming language for this particular part of the program is going to be Ruby. There are many reasons: 1. Apple will support it in 10.5 2. There seems to be a lot of support for it in the Mac community 3. Ruby developers seem to be Mac people. 4. There is better documentation than

I have 2 models right now: "users" and "posts". When a user creates a post I would like their id to be recorded under "user_id" in the "posts" table. Under the "user" model I have: class User < ActiveRecord::Base has_many :posts end And under the "posts" model I have: class Post < ActiveRecord::Base belongs_to :user
