similar to: FK constraints overrated?

Hello, As a rails newbie, i have stumbled upon some tutorials promoting migratons. I have thought, wow, cool and started using them right away. However, now that i am reading the RoR list on a daily basis, i have seen also mails ranging from ''migrations are not always the best'' to ''migrations are evil'' and even ''i would not use migrations even

Hi everyone! I have a problem with defining 2 fk referencing the same table. I have a Program table and a Team table. The Program should have an away team and a home team fk. From my understanding, "the fk column should be named after the class of the target table, converted to lowercase, with _id appended". But, in my case, I have 2 fk referencing the same table. How can I do this?

I''m looking for a plugin/whatever for preloading fixtures, to run tests with FKs defined. Specifying load order just doesn''t work for me, I need to purge the test db, load all fixtures, and only then create the FK constraints. Any suggestions?

When I create a child record I''m not automagically getting the parent ID put into the fk field. Does object.new take parameters that allows me to do that as part of the AR record creation? Or do I need to do it separately? Or am I missing the boat altogether ;-) Thanks, Bill -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

Is there any reason why AR has never supported foreign-key constraints? I can understand the lack of support for triggers and stored procedures since they are highly dependent on the database to create a wrap API around them. But this is not the case for foreign keys. This is specially important for open-source projects like Redmine/Chiliproject and Gitorious where you shouldn''t be

Hiya RoR gurus, I work at a .NET shop, but I enjoy learning Ruby. So, I wanna prototype some of our product''s screens using Rails (and hopefullly AJAX). One thing I''m not sure about, since I''m a Rails noob, is whether ActiveRecord will get along with our database... So I have two questions: * Can I have ActiveRecord get along with our PascalCase naming conventions?

There´s already a new version of the acts_as_taggable mixin available and look what it is capable of now: # Gets the top 10 tags for all photos Photo.tags_count :limit => 10 # => { ''beer'' => 68, ''wine'' => 37, ''vodka'' => ''22'', ... } # Gets the tags count that are greater than 30 Photo.tags_count :count =>

I was testing my models with this new library and I got: >> s.tag "warp" ActiveRecord::StatementInvalid: ERROR: inserción o actualización en la tabla «tags_stories» viola la llave foránea «tags_stories_story_id_fkey» DETAIL: La llave (story_id)=(8) no está presente en la tabla «stories». : INSERT INTO tags_stories ("tag_id", "story_id") VALUES

Hi people, As I stated in a earlier message, I am using Rails on my masters degree and soon I will have to port my application from a relational database (MySql) to a RDF semantic database called Sesame. At first, I thought that I could get away with most of the porting only by writing a decent database adapter, but then, examining AR closer, I could see that it has some strong dependencies

Greetings, I''m a newby to both "R"s in RoR. I would like to use Builder::XmlMarkup to generate my pages. If there is a working downloadable example somewhere, that would probably be enough. Otherwise, here''s what I want to do: With the following controller: class AccountsController < ApplicationController layout ''accounts'' model :account

Hi folks, Thanks to the community feedback on the 1st version, I''ve come up with a much improved version of the acts_as_taggable mixin.

We're trying to use samba to let our PC's mount view extended pathnames used by clearcase but they show up as empty. If anyone's used samba and Clear Case (by Pure Atria) and gotten it to work I'd love to hear how. thanks, Bill -- --------------------------------------------------------------------- William H.

I suspect this is a bug. Or a limitation. Problem: ---------------- When you include a STI class in a ''find'' : @results = Result.find :all, :include => :event , you are forced to specify the fk and the class name : belongs_to :event , :class_name => "Event", :foreign_key => "event_id" . Full code: ----------- class Event <

Hi folks, I''m wondering if it''s possible to use foreign key constraints on the join tables of a has_and_belongs_to_many relation. Specifically, I get this error when I try and delete a model I''m using, named saved_search, which is many-to-many with neighborhoods. Any ideas? Thanks for any help. :-) -Eric Code: @saved_search.destroy Error: Mupdate or delete on

Hi all. I have has_and_belongs_to_many association between models: Section and Content. class Section < ActiveRecord::Base acts_as_tree has_and_belongs_to_many :contents belongs_to :default_content, :class_name => ''Content'', :foreign_key => ''default_content_id'', :dependent => :nullify end class Content < ActiveRecord::Base belongs_to

I seem to have trouble getting DBD4 to create ActiveRecord-compatible DDL statements. I have a database with a series of 1:n relationships which should be easy to model. But, depending on the relationship type I use, when I connect them in the ERD it either: 1) starts cascading foreign keys like an avalanche, or 2) fails to add ''contraint fk_xxx foreign key (yyy) references
