Passing Arguments to before_filter
I want to put a before_filter in application.rb, as follows:
before_filter :do_something, :except_controller => [:admin]
def do_something(options)
options.stringify_keys!

end
Where I''m blocking is on how to get the ''options'' data in the do_something

path vs. url
When using named RESTful routes, when should one use the
generated ..._path helpers, and when the ..._url helpers? Say I did
this in routes.rb:
map.resources :users
Where should I use users_path, new_user_path, etc., and where should I
use users_url, new_user_url...?
Thanks!

negate the regexp in validates_format_of
Railsters:
ActiveRecord''s validation system puts other database systems to shame.
However, the newbies might not know how to write a regexp that
excludes a match, instead of tests for it. Understand - I''m just
asking this question to help them. I have been using Regexps since
''grep'' on Xenix! But the newbies here might not know how to do this:

A real puzzler: attr_accessor / create incompatibility?
Greetings,
I have a problem with attr_accessor and create seemingly being at odds
with each other in my environment. Here is the setup:
A simple class representing a US State (say, Maine for example):
class State < ActiveRecord::Base
attr_accessor(:name, :code)
end
In an IRB session, I type the following and receive the response

RoR programming style guide?
Is there a style guide for RoR? For example, I see that rails likes
to create things like
<% ... %>
<% ... %>
<% ... %>
and I''m tempted to write this as
<%
...
...
...
%>
but I''m not sure if doing so will make my code "look wrong".
Since I''m a beginner, I''d like to get into the habit of writing code

RESTful PUT and button_to
I''m working on a RESTful app, and I''ve hit a snag. Here''s a
simplified example of the problem. (Excuse me if this example code
isn''t strictly correct; I''m typing from memory.)
Suppose I have a table which models a simple counter. It has a single
column, "count":
class CreateCounters < ActiveRecord::Migration

Writing a breakable loop? If it gets a match it should stop.
I''m trying to write a function that will accept a rails URL, and see if
it matches one of my Rights. Rights are just controller URLs, so I can
manage access at the controller level (don''t need action level). What
I''m trying to do is take the url passed, and see if its access
controlled. If it is, the method should stop and return true, if not it
will return false. This

Mixing html tags and Ruby blocks
I''m trying to get the following idea to work:
<%= @column_names.each { |t| <td> t.downcase </td> <td>
@listing.send(t.downcase)</td> } %>
Essentially I want to display a form that has a left and right TD, with
the left TD being a column name and the right TD being the column data.
If there''s a better way (the Rails way ?), I''m all ears
