Rails - Jul 2005 - Dynamic Routing

Hi,

I was wondering if it is possible to make a route dynamic.

I am working with components and want to be able to call the component
with a different leading in path, or even from a sub domain.

I was trying map.connect ''path/:cnt/:action/:id'', :controller
=>
''otherpath/:cnt''

But was unsuccessful.

The only other way I can think of is mapping each controller, eg,
map.connect ''path/controller/:action/:id'', :controller =>
''otherpath/controller''

Regards,

Dylan.

There is an old patch on Trac regarding controller prefixes. That might be what
you are looking for. If so, I provide an updated version of the patch...

Hi Nicholas,

I found the patch on Trac and would be interested in an updated version.

Quick, possibly obvious, question about working with validation and
Single Table Inheritance. My STI seems to be working fine, but is
leading me to a problem with validations. For example, from the Beta
Book:

class Person < ActiveRecord::Base
  validates_uniqueness_of :login
end

class Customer < Person
end

class Employee < Person
end

class Manager < Employee
end

As you can see, I''ve added validation that makes sure that all records
in the persons table have unique login names. However, if I were to
do:

Manager.create(:login=>"pgf") and then do:
Manager.create(:login=>"pgf"), there is obviously an error.
However:
Customer.create(:login=>"pgf") generates no error.

This makes sense, since the Customer class is (presumably) only
checking records that have type="Customer", so it doesn''t see
the
Manager with the same login. So, my question becomes, is there a way
to ensure that validations check all rows in the table, not just for
the current class? Or am I forced to add a validation step that does
something with a Person.find_all within each subclass? I guess what
I''m getting at is that if I specify a validation in the Person class,
I want it to validate even subclasses in the same "context",
i.e. within all Person rows.
