I''ve tried and tried. I couldn''t get freeimage installed. I got mini_magick installed, but everytime I try Mike Clark''s tutorial, I get the error ''Size is not in the list''. I found some people fixed this by putting a sleep statement in their controller, but this didn''t work for me. Any help out there?

I want to create table called roles and then populate it with some new records...This doesn''t work. Is there something I''m missing? Craig class AddRightsAndRolesTables < ActiveRecord::Migration def self.up create_table :roles do |t| t.column "name", :string end Role.reset_column_information Role.new :name => "Users Admin"

Hi, I''m searching for a method of eager loading polymorphic associations under activerecord 2.0.2. After some initial google-fu I came up with a link to an enhancement that''s been added to edge: http://dev.rubyonrails.org/ticket/8119 Anyone have any idea how long that might take to work its way into a general release? I''m early in development now so I can afford to

Hi, lets say I have a a table, "Linkings" that I am using for polymorphic associations. One of the associations is to the "person" table, and there are several other associations. "Person" has 2 types, "slacker" and "suckup". It is modelled as such: class Linking < ActiveRecord::Base belongs_to :person belongs_to :linkable, :polymorphic

My app has an association that''s got me scratching my head. I have Users, and Images. A User has many Images. (Yes, another picture sharing app, but it''s for a small niche, and it doesn''t end in -r!) I would like to express a "Favorite" relationship between both Users to Users, and Users to Images. This seems like the opposite of the standard

Hi, seem to keep running into a wall here. I can''t find any resources on site navigation that can deal with any model being in the nav, allow nesting, and can dynamically update. So I thought about it for a while, and decided on a MenuItems class, which contained the position of the child in relation to it''s siblings, where the parent and the child were polymorphic. Then a given

I have the following models: class Card < ActiveRecord::Base belongs_to :deck belongs_to :front, :polymorphic => true belongs_to :back, :polymorphic => true end class TextContent < ActiveRecord::Base has_one :card, :as => :front has_one :card, :as => :back end The conflicting has_one declarations don''t work. What I need is

Hello, I''m just starting out with both Rails and Ruby, so I hope this isn''t too simple of a question - but I''ve been struggling to find a solution. I''m using the file_column plugin to handle image uploads and thumbnail generation. In addition, I''ve wrapped the image into a polymorphic table so I can have uploaded images associated with multiple

Hi guys, I have the strangest thing happening. The funny part is its doing exactly what I want to do, I just don''t understand how. Basically here is my model. class Role < ActiveRecord::Base has_and_belongs_to_many :users has_and_belongs_to_many :rights def self.names names = Array.new() for role in Role.find :all names << role.name end return

Hello All, I have a little challenge and I am not sure if this is even possible I am working on a dating/event site and few functionalities are similar that I want to centralize them. We have users which can have - favorite users - interest list - blocked users All these relations are like; User <-> Relation <-> User I was thinking I could have a class called Relation (with a

No matter what I try I''ve been unable to work how to get this to work with the cool ActiveRecord helpers. I''m not sure if it''s possible, Josh Susser''s blog suggests it is, but damned if I can work it out... I have: Container which can contain one or more Element. An Element is a polymorph of either a Container or a Chunk. An Element can exist in one or more

Hi, I''m trying to figure the most efficient way to model the following. I can think of at least two ways to relate the tables but from a client/server perspective! I''m wondering how to best (and elegantly)relate them from an AR perspective. A project has many people, A person can work on many projects at any time, A project has many roles, A role is performed by a person, A

I''ve been searching the web, wikis, and more, and I haven''t turned up examples of how to have multiple entities in a single-table inheritance related to anything. I have an addresses table, but multiple entities can have Addresses: both Person (which has 2 addresses) and Retailer. I''ve been told that I need to use single-table inheritance, and this was my attempt:

I am trying to get polymorphic relations to work for my app. What I am trying to do is explained by this picture http://iroll.org/code/ I can''t figure out the code for in the controller to create a new phone_number and assign it to a person. I have tried everything I can think of. A) do my models look correct? B) what would the commands look like in the console or a controller action

Hi there, I love the acts_as_* family that rails uses. I''ve also found I can create something similar by dropping the following code into my activerecord classes: class MyClass < ActiveRecord::Base class << self alias_method :count_with_unapproved, :count end def self.find(*args) options = extract_options_from_args!(args) if options[:conditions].nil? options[:conditions] =

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into
