Hello, I upgraded my application from Rails 2 to Rails 3 and ran into a problem. In rails 2 I could use the english name of the record to find it like: Page.find_by_name("Welcome") even though the user chose German as the language (which of course showed the German welcome page. Eversince I switched to Rails 3 (default_locale still :en) I can''t find anything by giving the

Hi Just curious if anyone can explain why using a dynamic find fails to work with << operator I have standard habtm relationship class User < ActiveRecord::Base has_and_belongs_to_many :roles Now when I assign a Role via << after saving the new User I get wierd behaviour but only when using the dynamic version of find i.e @user = User.new(p) if @user.save #

I''d like to always add a condition to any version of "find" (e.g. Thing.find(), Thing.find_by_name(), Thing.find_by_whatever) so that in addition to whatever conditions are set, an additional condition is set :conditions=>"user_id=#{current_user.id}" I''d like to make sure that a user only sees/edits/creates entries in the database that have the user_id

I''m sure this has been asked before but a quick search on the web didn''t give me any hints.. I''d like to do this: @person = Person.find_by_name throw_page_not_found unless @person Anybody know how to do this, do I have to manually tinker with the response object? -- Posted via http://www.ruby-forum.com/.

Hi, While viewing part of a long list of records, the user may want to do a Find of a specific record (for example, find_by_name). The found record is then displayed using the list view. I''ve searched the wiki and couldn''t find a sample or information that will help directly in implementing this function. Any pointers? Thanks! gk -- Posted via http://www.ruby-forum.com/.

I have a model layer containing Movie, Person, Role, and RoleType, making it possible to express facts such as "Clint Easterbunny is director of the movie Gran Milano". The relevant model and associations look like this class Movie < ActiveRecord::Base has_many :roles, :include => :role_type, :dependent => :destroy has_many :participants, :through => :roles, :source

I have a HABTM relationship between 2 tables : companies and services. I want to find all the companies who provide a particular service so I''m using @companies = Service.find_by_name(''servicename'').companies.

Hello all, It''s been a while since i''ve been doing any rails development, so i''m a bit rusty. Having found this: http://opensource.symetrie.com/api/better_nested_set/ it looks really interesting and useful for solving something i''m trying to get working. What i have (essentially) is the following models: class Group < ActiveRecord::Base

I''m attempting to wrestle an old DB into Rails. This relationship is giving me trouble: class Show < AR::Base has_many :segments end class Segment < AR::Base belongs_to :show has_one :media #this has no PK/FK relation end A Segment is "linked" to Media by Media.name, which is the result of concatenating Segment.name and Segment.part. As I said there are is no

Good Friday Everyone :-). These are my models: Problem -> has_and_belongs_to_many :tags Tag -> has_and_belongs_to_many :problems Now if a tag does not exist and I create it and associate it to the problem it works self.tags << Tag.create(:name => tag) But if I have the tag already in the DB and just want to link it to another problem it does not really like me. I do it

When I use find_by_name method I get LIMIT 1 result. > SELECT "users".* FROM "users" WHERE "users"."age" = 25 LIMIT 1 But the "age" column is not unique in my table and its value may repeat. So I expect that an array of records where "age" is 25 will be returned. But AR limits the query by 1. How to avoid it? Or is it the default
