mongrel_send_file gem plugin
served piping hot fresh from my svn repo:

This is a simple plugin to handle the sending of secure files from a
rails app. Here''s the typical process:
- Rails app authorizes user to download file
- Rails app sets file info in the session, redirects to custom URL

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:

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

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,

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

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
