Hi,
Is there a default method or class accessor that I can add to a Ruby class that get called if a accessor (Ruby like property) doesn't exit? I can then write some custom code to reply from like a array list read from a database where the value can be accessed like a accessor without me writing the accessor code (since if read from a ...
method_missing
*obj.method_missing( symbol h , *args i ) → other_obj*
Invoked by Ruby when obj is sent a
message it cannot handle. symbol is
the symbol for the method called, and
args are any arguments that were
passed to it. The example below
creates a class Roman, which responds
to methods with names consisting of

Does anyone know of a way to intercept dynamic method calls (particularly those that are going to raise RuntimeBinderExceptions) with a RealProxy? I was hoping to catch the exception and implement 'method missing' on top of that, but it appears to be thrown before the interceptor gets a look-in.
My test just looks like:

I have a class Foo which has several methods like button_0_0, button_0_1, button_0_2, button_1_0, etc.
I would like to be able to access these alternatively via the following syntax:
foo.button[0][1]
foo.button[1][2]
# etc.
I know I could just create a @button instance variable and iterate through all the button_* accessors and add t...

I come from a Java and Ruby background and I was wondering if there is any equivalent of "method_missing" in Erlang. I have looked at the documentation and the closest I can see is the use of erl_eval and erl_parse, but I wanted to know if there is any other way?

If my Rakefile does not find a task with a particular name, I'd like rake to instead create a new task by that name according to certain rules, if a file with the missing task name exists. But if it doesn't, I want to fall back to the default ("Don't know how to build task 'foo'!").
In short, is there a method_missing for Rake?

We have been using SubSonic to generate our DAL with a lot of success on VS2005 and SubSonic Tools 2.0.3.
SubSonic Tools do not work on VS2008 (as far as we can work out) so we have tried to use SubCommander\sonic.exe and are now hitting some problems.
When we regenerate the project using SubCommander\sonic.exe and try to compile we ge...
Here's the situation:
I have a User model, and two modules for authentication: Oauth and Openid. Both of them override ActiveRecord#save, and have a fair share of implementation logic.
Given that I can tell when the user is trying to login via Oauth vs. Openid, but that both of them have overridden save, how do "finally" override save...
In Ruby, objects have a handy method called method_missing which allows one to handle method calls for methods that have not even been (explicitly) defined:
Invoked by Ruby when obj is sent a message it cannot handle. symbol is the symbol for the method called, and args are any arguments that were passed to it. By default, the interp...
Hi all,
Currently we are using method_missing to catch for calls to SEO friendly actions in our controllers rather than creating actions for every conceivable value for a variable. What we want are URLS like this:
/students/BobSmith
and NOT /students/show/342
IS there a cleaner solution than method_missing?
Thank you!

Each user has many roles; to find out whether a user has the "admin" role, we can use the has_role? method:
some_user.has_role?('admin')
Which is defined like this:
def has_role?(role_in_question)
roles.map(&:name).include?(role_in_question.to_s)
end
I'd like to be able to write some_user.has_role?('admin') as some_user.is_admin?,...

I have been playing around with the dynamic abilities of powershell and I was wondering something
Is there is anything in powershell analogous to Ruby's method_missing() where you can set up a 'catch all method' to dynamically handle calls to non-existant methods on your objects?
