search for: const_get

Hi, I''m trying to write some methods which use a parameter to represent a Class name. A very simplistic example: def foo(class_name, conditions) x = class_name.find(:all, :conditions => "#{conditions}") end Unfortunately, this does not work. The only way around this problem that I can think of is to use eval: def foo(class_name, conditions) x = eval

HELLO other Rails-Core people! I''m trying to push changes to const_get in to ruby-core that will make our lives easier. I''ve pushed a branch of Ruby to github.

Hi all, running into a little problem here. I''ve a list of things with a "New thing" link beneath it. When you click that link, obviously, a new thing shall be created. Now, that works pretty fine for things that don''t have foreign keys, but for things that do it crashes, since there is not yet a thing.other_thing.name available. I suspect you can somewhere in

Hi, I wonder if there''s an easy way to access the associated Model class from its Controller. Something that would allow me to write snippets like the following: class PeopleController < ApplicationController def some_method person_model_class = self.some_method_to_retrieve_the_person_model_class() end end Cheers, Marco -- Posted via

Hello, I am trying to use the multi_search method, but I keep getting type error on nil objects, I send it [Model1,Model2] and it seems as though the class names keep getting clobbered and turn to nil, somewhere along the multi_index area. I tried to trace what was going on, but I got nothing, also, this only happens when there are actually hits(thank god, most of the time). Perhaps some insight?

I''m trying to dynamically create an instance of an object at runtime, from a String. I have a method that returns one of a number of Strings ("Car", "Motorcycle", "Bicycle"), and when I receive the String, I then want to instantiate one of those objects. Seems like there should be a way to do it in Ruby, but maybe I''ve been up too long --
