Hash flattening on paginator link_to
Hey
I need some help with pagination and the link_to in the view.
I''m trying to include a hash in the pagination link_to params and it
keeps flattening out my hash.
Example:
Here''s my hash called @answer:
"answer"=>{"6"=>"9bf31c7ff062936a96d3c8bd1f8f2ff3",
"7"=>"6f4922f45568161a8cdf4ad2299f6d23"}

Multiple (AJAX) Observers on the Same Field and MSIE
I have been using multiple observers, i.e., observe_field(), on the same
input field and relying on them to execute in the same order that they
appear in the page. This has been working fine in FireFox, but it does
not seem to work in MSIE; the requests come in and are processed in a
different order. Now, I''ve always been a little hesitant about using
this technique, but it always

Newbie - populating select list from db
Can''t seem to find an example of this anywhere - how do I populate a
select list in a form from a database?
I have a form to create a new task. The task is for a client, so there
should be a select list populated from my clients table. I thought this
would work:
<%= select ''task'', ''client_id'', Client.find_all, "id", "name"

Non model cascading selects
In my model I have a city_id. ON the form I am using a cascading select
to select the state, which then does a remote_submit to get the list of
cities (and hence the city_id) for the selected state. The problem that
I am having is that if I make a selection, hit SUBMIT and validation
fails, the original selected state/city is now reset (ie, the values
aren''t saved). Since they

pagination over custom-sorted collections?
I have a little web app where we need to paginate collections of
items. I''m trying to sort the collection and then pass it, sorted, to
a Paginator, and still be able to paginate through the collection,
across several pages, with the new sort order. The only thing I''m
doing differently from the regular scaffolding approach is this:
@order_pages = Paginator.new(self,

Pagination links with separator
Hi,
I have @result_pages and @results obtained from paginate in an action. I
want to show the pages as
1 | 2 | 3 | 4 >
The fifth page will show:
< 5 | 6 | 7 | 8 >
and so on.
How exactly do I render the paginator to give this effect? I guess I
will have to use pagination_links_each. But being new to Rails, I need
help.
Thanks,
Yash

Assigning to the foreign key on a belongs_to association
I''ve encountered what seems like an odd omission in the behaviour of
belongs_to associations: if you assign to the foreign key attribute,
it doesn''t update the associated object (or mark a previously loaded
one as stale) until you explicitly save or reload it.
Let''s say we have a Company model, which belongs_to :city :

We should have:

Pagination of Complex Queries
I''ve created a class method in my model called find_filtered. The intent is
that I take various params that the user has submitted, and let the model
build the query and return the AR collection, which is exactly what happens.
However, now I''d like to paginate the recordset. Everything I''ve been able
to find about pagination presumes that you have no pre-existing AR

before_filter order of execution
Hi
I''m trying to use before_filter to allow access to a site. Only logged
in users can view any object in the controller, but only users with a
access_level higher than 2 can view specific objects. My code is:

custom find methods and pagination
i''ve got several methods in my models i use to find based on certain
criteria...i''ve done this so the controller code is less cluttered, plus the
DRY factor.
example:
class Foo < ActiveRecord::Base
def find_by_something(something)
find :all, :joins => ..., :conditions => ...
end
def find_by_something_else(something_else)

embedding ruby code in a [flash :notice]
The ruby code in this isn''t evaluated...

Is there a way?

Newbie Q: "user" variable in every view?
Newbie to RoR -- as a long time Java Struts/etc. guy it is an awesome tool!
I have implemented some basic login/session stuff with the help of a great
tutorial, props to the author (
http://www.aidanf.net/rails_user_authentication_tutorial).
I have a trivial instance method in ApplicationController, which just grabs
the User object from the session.
def current_user
session[:user]
