...ulated somehow. So you can do something like this: (repeated from an earlier post and the README) class Mixture < ActiveRecord::Base serialize :color default_value :color, [255, 0, 0] end m = Mixture.new m.color # => [255,0,0] Here''s the README: http://mdaines.com/svn/plugins/default_value/trunk/README To install: (as usual) script/plugin install http://mdaines.com/svn/plugins/default_value/ trunk Thoughts, comments? -- Michael Daines http://www.mdaines.com

...releasing an extraction from an application I''m currently working on. It''s a small library for dealing with points and polygons, called Polygons. It really just implements some textbook algorithms w/ Prototype-style JavaScript classes. Check it out here: http://polygons.mdaines.com/ The demo on that page (Firefox/Safari only right now) uses the point- in-polygon function and a little trickery (nothing too involved, though) to make dragging non-rectangular objects way more natural. In the application I''m working on, I combine that with the rotation funct...

Can I set an application wide instance variable that is available for all actions...and their views? eg. class ApplicationController < ActionController::Base @current_user = User.find(session[:user_id]) end and everywhere I can call @current_user.id and I can get that object? Even down in the views? I could not get this to work... Thanks in advance, Jeff -------------- next part

I am currently caching a page that indexes blog entries. Paginate was used to break the entries up. Now when you click on next at the bottom of the page it is only reloading the first page. Im hoping, against odds, that someone here knows of a way to make paginate and cache play together. -- Posted via http://www.ruby-forum.com/.

Hello, I''m working with a postgresql table CREATE TABLE elements ( id serial primary key, c1 text default f1(), ... cN text default fN() ); But if I use de lines @element = Element.new @element.save the values that element take are the nextval in the id field and nules in all the other fields. How can I get the defaults? (but without rewriting the

Hi All: Just curious if anyone has figured out how to set a default date for the date_select helper. My application has a form with both a start date and end date select for the user. Since the period between the two is a minimum of 24 hours I wanted to have the start date default to Date.today (which it does automatically) and then have the end date default to the following date (i.e.

Hey All, I have a fairly basic question about the prototype.js library. First, I''ve been looking for documentation on this and I have yet to find it. If any of you know of any, please let me know. Since I''m new to both the scriptaculous and prototype libraries could someone explain why I would want to use the cumulativeOffset method and not to just grab the offset off

Hello, How can I catch the onmouseup event outside the ducument - means when the pointer is above window chrome (e.g. toolbar)? Event.observe(document, ''mouseup'', someListener) works only inside the document for me. Thanks in advance for your help! Thomas -- Posted with http://DevLists.com. Sign up and save your mailbox.

I had a beginner''s question. I am testing the create action on my controller. I wanted to fetch the ID parameter of the newly created object, so that I can make some assertions on it. But I can''t seem to find an elegant way of doing that. Of course, might create action redirects. That means that @response.redirect_url is something like "/show/8". So I could pluck

I apologize if this is a very simple question; I''ve searched the forums, wiki, Google, and Agile Web Development with Rails to no avail. Is there a way to put conditional validation in the model? For instance, if I want to limit items a user can add unless the user is an admin? My current code is: validates_uniqueness_of :user_id, :scope => ''event_id'',

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1". If not, should I make a hash with my custom names?

wondering if anyone tried this patch. (i havent, seeing as its 1228 lines long, 10 months old, and cant take serious a patch many orders larger than competing web frameworks) in many cases i want to keep about 10 things around, eg recent searches, new items (spanning multiple classes), referers, page views, without logging them for perpetuity. so i guess this isnt a normal queue, more like a

I love the routes feature for RoR...until now. I''m trying to write tests to make sure my urls are correctly mapping to the routes I expect them to map to. This is driving me nuts because I simply can''t get any of my tests to pass. I have thus concluded that routes must work differently than I thought. I will try to explain my understanding of how routes work. Via this

Hi, I just put together a little mixin to provide pseudo-RESTful services in camping apps. Basically, it looks for a hidden _verb field in form posts, and sets the @method to the supplied value (e.g. put or delete - which browsers don''t support). This lets you define put and delete methods in your controllers. Groovy. Code: http://pastie.caboo.se/22613 Is there any permanent repo of

I have some code working that lists only items from a particular user. The code in my list action finds the user and then conditionally lists only his/her items: def list user = User.find(session[:user]) user_id = user.id @product_pages, @products = paginate :products, :per_page => 10, :conditions =>[''user_id = ?'', user.id]

Hi, I''ve been playing around with using DBI instead of ActiveRecord ''cause I just love to beat myself up! ;) Is this an okay way to do this, or is there any other more creative ways? require ''dbi'' module MyApp:Models class DB def self.dbh DBI.connect(''DBI:Mysql:dbname'', ''username'',
