I''ve got User has_one Shop. Rails is not validating when I tried create_shop or build_shop, neither in the browser nor the rails console. My code: class Shop < ActiveRecord::Base attr_protected :user_id belongs_to :user validates_presence_of :name, :primary_address, :city, :country_code, :currency end class ShopsController < ApplicationController before_filter

I''m sure there''s something right under my nose that I''m missing. I have two tables with two parallel one-to-many relationships. I wish to use the :finder_sql parameter to essentially ''or'' the two foreign keys. What isn''t working for me is performing a ''sub-search''. Let''s say the tables are "stores" and

Hey all I seem to be having some problems with my relationship between a few tables... If i then run the following query in mysql, i get the data i want.

For some reason I am just not able to get this. I am trying to setup an organizational hierarchy, so I have a organization which works fine. From there I want to be able to define new divisions, departments, areas, etc. For creating a Division, my original thought was to pass the organization''s id to the new organization unit form, and then do a Division.new(:organization_id =>

Could someone explain this http://blog.leetsoft.com/articles/2005/10/31/scoped-databases in a way that can be understood with an example if possible. Tobi Lutke has started to explain but it does not make any sense. "Since rails 0.13.1 we support calling class methods over associations." what?? give an example. also "The Shop object is figured out at the beginning of each

- MODEL - class Document < ActiveRecord::Base has_one :user, :class_name => "User", :foreign_key => "fkey", :conditions => "user = ''NAME''" end - GENERATED SQL (per the .log) - SELECT FIRST 1 * FROM table_name WHERE (table_name.fkey IS NULL AND (user_id = ''NAME'')) What I can''t figure out is

has anyone ever seen that: c:\rails\test>rake migrate --trace (in c:/rails/test) ** Invoke migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute migrate rake aborted! undefined method `string_to_binary'' for ActiveRecord::ConnectionAdapters::ColumnDefinition:Class

Hi All, I realise this is off topic, but its likely the best place to ask! I sent an email to snom support a few days ago but have yet to recieve a response.. Perhaps some one has found a solution to this problem already? I've searched the mailing lists and google and found nothing useful. I've also read Snom's mass deployment documentation but thats no real help in this case.

Hi, Found a simple example breaking on moving to 2.2 from 2.0. This example illustrates the usage of nested :include finder options. class Book < ActiveRecord::Base has_many :distributors end class Distributor < ActiveRecord::Base belongs_to :book has_many :agents end class Agent < ActiveRecord::Base belongs_to :distributor has_many :shops end class Shop <

Hello everybody, I've got a problem concerning the function unique. I have got a data.frame "shopdata" with 1000 shop which were evaluated at different points in time. With function subset I chose those shops with more then 10 employee and store it in data.frame "bigshopdata" with 700 shops. bigshopdata=subset(shopdata, shopdata$employee>10) Now I use

Let''s imagine we are modelling a company that have several shops. I have a Worker model and a Shop model. A worker belongs_to a shop, and each shop has_many workers. But, in a shop there''s a distinguished worker that is the supervisor create table shops ( ... worker_id integer -- the supervisor ); How would you express this relationship?

Hi! I need some help, my partner and I have hired an app development company to create an iPhone app that allows shops to list their inventory and advertise their specials, there is also a back end admin website that shop owners can login to that allows them to update their inventory and specials. The admin website communicates directly with the iPhone app so that any changes made are shown on

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!).

Hi, The following patches are just copying some functionality that exists in the asm cmdline code into the C version. There's still a few more things to do but we're getting there. The following changes since commit 8c576f1fe03e34879921311f46613a35c6530000: Merge remote-tracking branch 'mfleming/for-hpa/elflink/fix-compiler-warnings' into elflink (2011-03-16 12:53:58 -0700)

I'm trying to understand something that just doesn't seem to compute. How can companies like Cisco justify selling their hard phones for as much as they do? I know there is a matter of recouping R&D costs but when you look at the iPhone with all its amazing features for less than $500.00 it just doesn't make sense. Am I the only one that thinks this?

Hi! I just ran the first few Rails tutorials and I''m really impressed at how quickly I was able to get something up and running. I''m slowly emerging from the stone ages, and leaving my powerbuilder behind ? yes, I know, keep the snickering to a minimum please!
