Ugggh..another recipes question
sorry, because it seems that I need more explanation on this Rails
Recipes authorization -
I finally got the code working but after using the login I get this
back from Rails-
Routing Error
No url can be generated for the hash {}
I''m guessing it''s coming from the redirect-
def login
if request.post?
session[:user] = User.authenticate(params[:first_name],

Rails Recipes question - authenticating users
Didn''t think I''d be back so quick with another question but here goes:
In this recipe for the signin or login (as I call it) there are these
two lines if the user authenticates correctly:
session[:user] = user.id
redirect_to :action => session[:intended_action],
:controller => session[:intended_controller]
So I''m not seeing anything in the way of an explanation

before_filter: nil vs. true vs. false
Folks,
My understanding of how filters work is that I should return true if
everything is ok and false if not. How does the filter below work
then (from the Rails Recipies book)?
It would return nil if there''s a user in the session. Does nil count
as true?
before_filter :check_authentication
def check_authentication
unless session[:user]
session[:intended_action] =

Redirect back to last page?
I have a few pages where a user may do something (add tags, login, etc)
and I would like to redirect them back to the last page they were at
before calling that action. Is there an easy way to do this?

Reading floating points into a field stored as Integers
Hi, I''m trying to follow the "AWDR" example of storing certain types of
numbers (in my case, percentages not money) as integers in the
database. I understand from the Depot application how to format the
output to have 2 places (or n places for that matter) decimal.
Now, I"m wondering about the input. It''s more natural for people to
enter numbers as

Login form question
I''m using Rails Recipes to create a login form but instead of username
and password, my setup is firstname, lastname, password.
I seemed to be gramatically challenged and not sure how to set up the
parameter list. Can anyone offer up a suggestion.
The book shows the method starting like:
if request.post?
user = User.find(:first, :conditions => [''username = ?'' ,

Rails Recipes Book: Authentication
Hi,
The user/login management system in Chapter 31: Authenticating Your
Users and Chapter 32: Authorizing Users with Roles of Chad Fowler''s
Rails Recipes looks reasonable and adequate. However, when I ran the
Chapter 31 code, I get the following error:
Username or password invalid
And I am not even given the chance to sign in; that is, the signin form
does not appear at all.

Tutorial for Queries
Hi! I''m looking for a good tutorial that explains the main points of
performing queries with Rails. I do have AWDWR and have read the
section on ''find'' but I''m looking for something that goes into more
detail on how to perform queries across tables.
Abstracted from my current application, this is an example:
* person has_many sites
* site has_one room

Next/ Previous record
Hi, Quick question (which means that I think there should be an easy
answer)...
When I am in the "show" view, I''d like to add 2 links, one for previous
and one for next record so that the user can go on to the next "result"
without having to go back to the ''list'' of results. However, I can''t
find my way about this problem :-S

ActiveRBAC?
How''s the experience with using ActiveRBAC? For my "next 4 days with
rails" :P I''d like to consider adding Role-based access to the To-Do
List application in the original "four days w/ rails" tutorial.
Just wondering if ActiveRBAC would be a good place to start? Thanks!

Understanding Common Views
Hi Everyone,
I''m trying to formulate my thoughts on how views work in RoR and I
understand the basic bits -
1. Every controller has its own view defined using rhtml files in the
views/[controller_name] folder.
2. There is one "view" file (rhtml) for every in the controller and has
the same name as the method.
3. For portions that are common, partials can be used - file

InstantRails - command "rails" does not work
Hey,
I installed InstantRails 1.7 (on Windows XP Home). I unzipped it with
7-Zip in D:\InstantRails (no spaces in pathname + short pathname) to
avoid UnZip-problems. I followed the installation instructions. The
cookbook-example works fine.
But when I want to create an own project with "rails projectname", my
computer says something like "The command "rails" is either

Syntax Problem
In an *.rhtml, why do I need to add <% for product in @products %> in
order that I may call an <img class="list-image" src="<%=
product.img_url %>"/>. Is there not another way to skip the "for
product" line? I really dont want to include it. I tried @products =
product but it does not work. Can anyone help shed light on this matter?

Problem with Pagination
Hi Guys,
I am trying to paginate the results from a search. When I use actual
constants in the search conditions, it works fine:

:conditions => [''e_date >= ? AND
e_date <= ?'', ''2006-07-12'', ''2006-08-12''],

Accessing the name of a controller''s module?
If I''m redirecting to a log in page, and saving the controller and
action name in the session hash, how do I also save the controller
module?
After the log in is completed, I can''t redirect back to the originally
directed page because it''s in a different controller module. For the
controller action name I can use the ActionController instance method

Change password
Is there an addition to the Rails Recipe or the method in AWDWR to allow
a user to change his/ her password? I have put something together that
does all the work again - mostly because I''m not sure how to leverage on
methods like ''password='' that are defined in the model. Has anyone got
a ready sample that I could learn from?
Right now, I''m basically
