associations for a risk and display some field information from each as

DRY DRY DRY
Hello everyone!
Ive been on rails for the last month or so and really enjoyed this
framework.
However its very hard to find documentation on how to do things right!
For example every beginner after a while realizes that having similar
CRUD actions in every controller and views for them is not DRY at all!
Few days ago I found http://dereksivers.com/rails-shared-controller.html

Dynamic forms containing collections
Hiall,
I have the following problem: I need to use forms containing
collections (i will call them FCC), and I want to construct them
dynamically, as I need to deal with quite large forms (more than 600
input fields).
The variables @model_name and @field_name contain the proper model and
field names as strings, which is enough for "normal" form input
fields. (i.e. the "if

find_by_sql without a model? how to do this?
Hi,
I''d like to do a "find_by_sql" without a model (e.g. <model

find_by_sql column ordering defect?
Hello.
I have a program that accesses a metadata (translation) table for column
names as well as the ordering of columns for a specific model. Also in
there is a collection of bool options such as column_visible_on_form,
column_visible_on_screen_quicklist etc. The idea is that our customer
can specify to a certain extent how their layout/user interface will
appear.

How to organize models into modules

Rails app into modules. I have created the directory structure as
follows:

And my model class code is:
module Module1
class Mymodel
...some stuff
end
end
How do I include this model in my controllers without referencing it as

<model>.update(...) not calling before_update callback.
Hi,
I''m doing a <model_name>.update(....) but I''m noticing that my
before_update callback is not being called. If I do a find and then a

my case is that I''m not able to set all my attributes in one shot by

dynamically generating a controller and appropriate routing
I''m working on a library similar to acts_as_taggable. I''d like it to be a
simple, one file drop-in: i.e., put my_library.rb into RAILSROOT/lib/ and
have everything work. However, the library requires a controller to render
some stuff, so I need to be able to create the controller class, set the
routing, and extend the controller at run-time from within my_library.rb.

db connection returns stale values
Hello,
I''m working on a rails 3 app for a legacy oracle db.
I have a controller that saves object graphs
(accepts_nested_attributes_for) but I noticed the post-update JSON response
still contains the pre-update values.
After some debugging, it appears the database connection is returning stale
values (find(), reload(), etc., all return pre-update values; but SQL
