prototype.js: enumerable mixin for hash broken
Hello everyone.
I am not sure if this is the right place to post, please redirect me
if there is a mailinglist more specifically dealing with prototype.js.
After playing around with the very inspiring prototype library I have
found a rather annoying thing, that makes the usefulness of the
Enumerable mixin for Hashes
questionable, if I am not totally wrong (again :-).
Here an example:

Specifying mixins
Hi folks,
Can anyone share some accumulated wisdom about the best way to spec
mixins in general, and (Jamis Buck-style) ActiveRecord "concerns" in
particular?
The standard situation here is that there''s a bunch of functionality,
related by concept if not by implementation, that one wants to inherit
in many different classes (e.g. ActiveRecord models) witho...

model mixin module madness
If I have several models which exhibit the same functionality, it seems
makes sense to create a mixin, ''include'' it in each model and save
myself some work and repeated code.
Where can I define a module which will be available to all models? I
can''t seem to find a documented place for them.
Alternatively, is there a Rails-standard way of achieving the effect?

PROPOSAL: Validations as Mixin
It seems to me that Validations are quite useful for many objects, even
ones having nothing to do with ActiveRecord.
Common examples are Contact Us forms, multi-step forms, web service
paramater validations, etc.
I took a look at the source for Validations, and it seems that it is
very independent from ActiveRecord. I caught only three depenedencies:
1. validates_numericy --> depends on

ActiveRecord::AssociationTypeMismatch (User(#54754560) expected, got User(#54510280))
i keep getting this AssociationTypeMismatch error. i think this could
be a bug related to ruby/rails when using mixins. heres a short
version of my code:

require ''friend_invitation''
require ''friendship''

NOOB: ratings/voting mixin or code example?

her photo in a calendar.

whatever would be greatly...

Auditing mixin for model classes. Small problem
I want to include common auditing functionality in my models. This
involves storing the changes made to a model in a seperate table :
I have created the functions in an Audit module :
module Audit
before_update :before_changes
after_update :after_changes
def before_changes
old=self.class.find(id).attributes
@changes=[]
attributes.each do |key, val|
if val != old[key]

RESTful mixin, mixin repo?
...sers don''t support). This lets you define put and delete
methods in your controllers. Groovy.
Code:

Is there any permanent repo of little code snippets/mini-libraries for
Camping? Is the wiki the best place? I think a lot of camping code
could be re-used via mixins and it would be nice to have a
Camping-forge type place to go find existing work.
Cheers,

derive.js - Ruby-esque derivation/mixins for Prototype
...some modeling
issues I was having on a large JS project.
I know there have been serveral alternative "write JS in Ruby" type
efforts, including ruby.js, rb2js, and prototype.js itself, but I was
hoping to keep it as light as possible while gaining the most powerful
aspects of derivation/mixins/callbacks. Much like the prototype
library, I''d like it to have an air of Ruby without trying to twist a
language I actually like (JS) into something it''s not.
It''s cleaned up a lot of the project I was working on, but I''m sure
there may be some additional compa...

subclassing vs mixins, which one should be used?
...ds from that(competent at rails
and ruby, but grasping for that intermediate level here). I know that
Enumerable is a mixin that is included in arrays and hashes, etc and
that I can create modules. (where should I put them in rails?). Does
anyone have any good information on subclassing in rails vs mixins?
Tutorials, good write ups or books to help me understand further? Even
your own advice would be great.
Thanks ahead of time

mixin behavior
Hi, all,
I need to DRY up some code in a few models. My first inclination,
having come from the Java world, was to go with an abstract class.
After a bit of reading, I then decided to follow the mixin route
instead. Now I''m running into trouble, most likely from a few basic
misunderstandings.
There are three models I will be using to average and count rating
data by executing a

[UHH] any blogs sprung from camping?
Hello,
I just joined the camping list. I was trolling the archives when I saw this:
--
The biggest problem in Camping is authentication. This is a problem I
propose to solve by providing an extension. That little bit of code
uses the path to allow/disallow urls. That way it is unobstrusive. In
the future I would also like to make an OpenID client and server for
Camping.

Mixins
If I want to write a function which will be available to views, I write
a helper function in one of the places set aside or that very task by Rails.
If I want to write a little suite of functions to be mixed in by a
number of model classes (but not all), where do I put them? Plug-ins
look like AN answer, but they also seem a little heavyweight for simple,
project-specific tasks.

Works in model but not in mixin
Disclaimer: RoR newbie. Using the acts_as_taggable plugin.
As an exercise I wanted to switch from the destructive TAG_WITH method
to adding tags while preserving the existing ones. On the surface this
seemed easy enough and eventually I got it working. However, the
following method:
def add_tags(list)
Tag.transaction do
Tag.parse(list).each do |name|

Using mixins versus delegation
I''ve been working on a plugin called Http Test where I add HTML
validation and link checking to controller and integration tests
through an after filter in ApplicationController. I used to mix in a
bunch of methods that I needed into the ApplicationController class,
but to me this had a bad smell, so I broke much of the code out into
separate classes that I delegate to.

mixins not reloaded as expected?!
Hi guys,
in development mode a module mixed into a helper class seems not to be
reloaded
inside app/helpers:
class TestHelper
include EvenMoreHelp
#foo
end
module EvenMoreHelp
# bar
end
the contents of #foo get refreshed, but not #bar...
is there a way to fix that behaviour.
I intend a full reload in development mode for obvious reasons.

Mixins?
As is often the case when I tackle a new platform/language, I get the big
picture very quickly (because frameworks are frameworks are frameworks) but
its the nitty-gritty of the language that bogs me down...
So I have some similar methods on a few of my model classes that I wanted to
push into a helper. Now I reckoned that the Ruby way was to create a module
and mix it in with include. However, I

Query Mixin by Duane Johnson
Hello
At the start of October, Duane Johnson announced the Query mixin plugin on
this list. The code was attached to the announcement email. Unfortunately,
I''ve not been able to locate the attached code. Goggle has not helped me
this time. Could somebody forward it to me?
Thanks in advance
