Ok, so now Users need to be associated with Organizations. I''ve created a migration and added a ''organization_id'' column to the users table. I want the default organization_id to be the first Organization. So I have :default => Organization.find(:first). But it''s complaining about not being able to find the constant ''Organization''. Any

I have a model Product with an attribute ''brand''. Currently it is a simple attribute, however, I am migrating it to a separate model Brand so that I can have other attributes with each brand. I created the the model and created and ran the migration to create the new table. So far so good. Then I created a separate migration to transfer the data. The up method

Hello, I have a tree structure that needs to be converted into a nested set. A great deal of work has already been done on the tree items, so maintaining the integrity of the id''s is mandatory. However I need the ability to access entire branches of the tree, which is what Nested set does. Does anyone have any suggestions on how to efficiently transfer the tree to the nested set and

Hi all, I''ve installed paperclips but paperclip is not saving the files my model has has_attached_file :attachment,:styles => { :medium => "300x300>", :thumb => "100x100>" } and i have db migration as class AddAttachmentToPolicies < ActiveRecord::Migration def self.up add_column :policies,

It can be quite hard to manage a pool of 40-50 VMs without informations about the OS running, the contact (which is the only one to know when the vm can really be destroyed) or an End Of Life date. This patch add those fields, and rework a little the VM list view, in order to show gracefully those new fields. It has been made at the expense of UUID, Total Run Time & Load fields. Since those

Hi list, My tag_question_user join table is not currently a full-blown model. It doesn''t have a primary key - just tag_id, question_id, and user_id. I now want to add a primary key to this model (because I want to add a "description" column as well so users can describe the tag. I''m not sure how to add this using migrations. Here is what I have: class AddNotesToTags

This seems pretty brain dead: add_column :types, :notify_on_create, :boolean, {:default=>true, :null=>false} $ rake migrate Error: ERROR: column "notify_on_create" contains null values : ALTER TABLE types ALTER notify_on_create SET NOT NULL Why doesn''t Rails set the new column to true, as it''s supposed to default to? I tried :default=>1 as well (same

I dont want to delete the records from my tables but just set a column is_deleted to true. What is the best (clean)way to implement this? Is there any way of defining a model which includes only a set of records which satisfy a certain conditions.eg a condition to include the records for which is_deleted is false some thing like this def User << ActiveRecord::Base :conditions=>

Dear Rubyists/Rails gurus, Though I''ve successfully completed the various Rails tutorials online and the Depot application from the Agile Web Development with Rails book, I''m still pretty much a Ruby/Rails newbie. I''m trying to learn by writing my own simple blogging application, but I''ve run into a problem that has had me scratching my head for a few days now.

I''m having a silly little problem with migrations.  All I''m trying to do is to add an SSN column to my Employees table.  I generated a migration which looks like: class AddSsn &lt; ActiveRecord::Migration def self.up     add_column :employees, :ssn, :string end def self.down     remove_column :employees, :ssn   end end When I run this, however, I get: &gt;rake

Hello! I am trying to figure out how to implement *logical deletes* instead of physical deletes using ActiveRecord. Basically, in many applications that deal with E-Commerce, you really can''t physically delete almost anything, because records must be kept for auditing and customer service tracking purposes. In the past, I''ve implemented logical deletes as follows: 1.

Please tell me I''m just confused, but this is very strange. I have a migration like so: class AddLevelToRequest < ActiveRecord::Migration def self.up add_column :requests, :title_levels, :string end def self.down remove_column :requests, :title_levels end end Run the migration, and from the console do: >> r = Request.new => #<Request:0x31a243c

I''m no good at SQL and I have a question that will hopefully be fairly easy to answer. I''m using acts_as_paranoid which instead of deleting a record adds a deleted_at column with the datetime the row was deleted. I want to have a find_by_sql filter out any row where deleted_at is not null. I have (at least the relevant parts): #a couple working filters here. filters <<

I''m working on a bugtracker application in rails. I have a Bug model and I want to add a Priority to the mix. A Bug can have one priority. I generate a Priority model, modify my Bug model with a belongs_to :priority and create my migration like so: class CreatePriorities < ActiveRecord::Migration def self.up create_table :priorities do |t| t.column :name, :string,

So I have this fairly basic migration bit of code class AddCounterCache < ActiveRecord::Migration def self.up add_column ''products'', ''backlog_items_count'', :integer, :default => 0 end def self.down remove_column ''products'', ''backlog_items_count'' end end What I want to do in that is automatically

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

Hi all, I''m confused about how migrations work. I''ve been using them for a couple of weeks but haven''t had any serious rollback issues yet. Just now I added a field to a table with a migration and ran "rake migrate", which added the field as expected. This was in the file db/migrate/007_mymigration.rb, making it version 7. Later I changed my mind and
