ActiveRecord::RecordNotSaved - bizarre behaviour.
Hi. I get a RecordNotSaved exception when trying to create a user record. The error: User Columns (0.005930) SHOW FIELDS FROM users SQL (0.000465) BEGIN SQL (0.000466) COMMIT ActiveRecord::RecordNotSaved (ActiveRecord::RecordNotSaved): ... As you can see, there''s no INSERT SQL generated, which is the root cause of the problem. In my user model, I have the following

Tableless ActiveRecord attribute and my aching head
I beat my head against a wall for almost 2 hours with this issue. My first problem was easily solved. I wanted a class that could use ActiveRecord''s validation capabilities but without using a table behind it (I would be persisting setup information in the session, but the initial setup parameters come from a user input form) No problem...found this link which got me up and running

Change to set_fixture_class
So, I sat down to use set_fixture_class, and it bombed on the first thing I tried: set_fixture_class :content_drafts => "Article::Draft" I made a quick patch, and I''d appreciate a quick run through your tests to make sure it doesn''t disturb anything: http://dev.rubyonrails.org/ticket/4095 As I was typing this, I realized that the string gives us no benefits.

Activerecord equivalent of the SQL "SUM()" function.
Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <

boy, that mongrel_upload_progress handler sucks!
I started actually using the upload progress handler, and noticed it was leaking memory over time. Looking at the code, I noticed that cancelled uploads weren''t being cleaned up. I bugged Zed about adding a request_abort callback to handlers, but I found a simple way to monkey patch that in: # config/mongrel_upload_progress.conf # yes, this file is being used with -S meaning

Change to has_many :through associations
Hi everyone. I''ve made a default change to has_many :through associations that I felt was important to make before they''re released. This is after some tickets and confusion I''ve seen regarding has_many :through. class Connection < ActiveRecord::Base belongs_to :user belongs_to :channel end class Channel < ActiveRecord::Base has_many :connections

Help with JSONified objects from ActiveRecord
Hello guys, I''m trying to return a custom JSON response to a client frontend. The object I''m trying to return is a User, with some associated Locale data. So basically I need to put the User data and his Locale in a "data" property in the JSON response. If this worked, it would be perfect: json = Hash.new json[:success] = false json[:data] = User.find(params[:id],

Merb + attachment_fu
Merbists, I saw a note in the attachment_fu source code regarding supporting Merb[1] as well as a post on the Caboose forum[2]. Has anyone gotten Merb working with Rick Olson''s attachment_fu to handle uploads for a Rails app? I''ve hacked together something, but it''s not pretty. Besides fixing the TODO mentioned in the attachment_fu source code to support Merb

RE: How to test for controller
There is a reason the controller is called *controller*. The controller should be making this type of decision. I would do it this way: Class FooController < ApplicationController def bar @side_nav = :display_admin End def baz @side_nav = :hide_admin EndEnd In the view: <% if @side_nav == :display_admin %> ... <% end %> In your application controller, you can set

ActiveSupport JSON working?
Hi, I am trying to convert a hash to JSON using ActiveSupports built in .to_json. I am doing similar to the example below but are there certain strings that could go in place of ''bar'' or ''rez'' that will break the to_json method? I am using a very long string from rjs output in place of ''bar''. Perhaps .to_json is not ready yet? Thanks, Peter

overloading to_json with JSON gem installed causing error
I installed the JSON gem because I wanted the JSON parser. Before installing the JSON gem, overloading worked fine. Before I remove it, I''d like to see if anyone has an idea of what is going on. It''s the only JSON parser I''m aware of, so it would be a bummer if it didn''t work. After installing, if I overload the to_json method in the class, it gives me the

validations.rb of ActiveRecord - bug or misunderstanding?
Either I''m not understanding how things are used, or this might be a bug in ActiveRecord. I''m using version 1.13.2.

should a AR object be able to see backwards?
I have two models, Stop and Station, they relate one station to many stops. Stop has_one :station Station belongs_to :stop So I can do @station.stops, but I cant do @stop.station, is this right? For example in the view I have: <% for @stop in @stops %> <tr> <td><%= @stop.station.name %></td> <td><%= @stop.time.hour.to_s + '':''

Harmonizing JSON/XML serialization
The way Rails handles root nodes in JSON and XML serialization is inconsistent. This has been discussed before: https://rails.lighthouseapp.com/projects/8994/tickets/2584-232-activeresource-json-doesnt-send-parameters-with-root-node This seems mostly taken care of with ActiveModel::Base.include_root_in_json, especially if/when it ends up in ActiveResource. However, there is also the issue of how

Using find_by_sql to get the sum of a column
Hello, I was wondering if there was a method in Rails that returns the sum of a column. For example, I have a column called ''score'' and writing a SQL statement such a ''select sum(score) from table_name'' does return the sum of the values in the column. In the past (not too long ago being a newbie), I defined all sorts of methods only to discover that Rails

to_json in Rails 2.0.2 not generating proper json?
I am using Rails 2.0.2 and trying to use to_json to generate json. I notice several problems. 1) datetime field such as created_at mapped to "created_at": {} 2) :except does not work, @post.to_json(:except => [:created_at, :updated_at] still gives me "created_at": {}, "update_at": {} 3) problem with escaped char mapping: ''<'' mapped to
