Hello guys, I''m a newbie in RoR and I have a problem. My DB structure is ====================================== topics table : id(int,11) name(varchar,255) categories : id (int,11) topic_id(varchar,255) name(varchar,255) ====================================== --Models:-- class Topic < ActiveRecord::Base has_many :categories end class

I''m trying to use collection_select, but it''s not working as I expect. The list populates correctly but the current value is not selected. @question contains a topic (via topic_id), and @topics is the list of all topics. Here''s my attempt to create a drop-down list of the topics. form("question") do | form | form << content_tag("b",

I''ve created several different Rails applications but I''m running into the same trouble with each one. Lets say I create an app called Test. I type ''rails test'' and it generates the directory for me. Now I edit my database.yml file. Then I create a database with Postgresql by typing createdb test. Now I go into Postgresql by typing ''psql

Is it possible to put conditions relative to the current instance in has_many''s :conditions? For example, in a forum app: class Post < ActiveRecord::Base belongs_to :topic has_many :self_and_descendants, :class_name => "Post", :order => "lft", :conditions => "topic_id = #{topic_id} AND (lft BETWEEN #{lft} AND #{rgt})" end With the

I have a User and Topic model. A user subscribes to a topic, so there is a many-to-many relationship between User and Topic. So my User model object is using has_many_and_belongs_to :topics and vice versa. I want to find all the topics that a user has *not* subscribed to. This is what I''ve got: @user = User.find(params[:id]) @topics = Topic.find(:all, :conditions =>

So I have the following model class Topic < ActiveRecord::Base belongs_to :topic has_many :topics, :order => :position acts_as_tree :order => :position acts_as_list :scope => :topic_id end that I use for a site''s navigation. Everything (list, create, edit, even the drag&drop sort) works fine, except the destroy function, which the vanilla version def destroy

Hi, I have implemented some RJS code and I have the same exact code in 2 different places. In one place I get the error "Element.update is not a function" and the other place works fine.

The rails docs are so horrible on the collection_select method. They need to show a *complete* form, and show two examples: one that calls f.collection_select(), and another that calls collection_select(), and explain the differences. Given this line: f.collection_select :topic, Topic.all, :id, :category What the !@#$!@#$ is :topic? -- Posted via http://www.ruby-forum.com/. -- You received

I got a WD 1TB My Book with eSATA/USB/Firewire400 connectivity to backup data on a client Centos 5.1 machine. USB 2.0 works fine out of the box but is rather slow, Nautilus predicts about 1+ hour to fully backup just one day's worth of data or about 100GB. So I was hoping Firewire would be faster, which is why we got the version with all 3 interfaces to experiment with first. Following the

With ref to my previous post: http://www.ruby-forum.com/topic/180356 I am now able to access items from topics controller. However, now I need to add sub-item e.g.: An item itself could have many sub-items. So my items model is like: class Item < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:topic_id] validates_presence_of :topic_id, :title, :owner, :position

Hi, As I understand, composite primary keys aren''t supported in ActiveRecord yet. May I ask if there are plans for this feature? Better yet, if this feature is under development, how''s the progress going? I''m not trying to use legacy databases. I tend to think that using multiple integer column id''s (composite primary key) are often natural way to

Suppose I have three tables - authors, posts and topics. Every post have a topic and every topic has an author, so I have posts.topic_id and topic.author_id. When the author is guest (not registered), author_id is nil. I need to find all the posts (in one query) where every post have all the information of the topic and the auther, so if p is one of those posts I could get the name of the
