Does the duplicate clone method of Position serve a subtle purpose that I don''t understand? I feel kind of foolish even asking, but ... I just don''t get it. I''ve been looking at this for a couple days now and as far as I can tell, the first definition is useless as it gets overlaid by the second one. I don''t see any closure trickery going on here, either.

Hello! I''m 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

I''m releasing a very small plugin that allows you to specify default values for fields in models. Ordinarily, you might do this in your schema, I guess, but then it''s awkward if you need that on a serialized field or need your default values calculated somehow. So you can do something like this: (repeated from an earlier post and the README) class Mixture <

Hi, 1. I have 2 panes, each having approximately 45-50 slides, all the slide images are 110x82 pixels in size, enclosed in their respective div''s. 2. These divs are further enclosed in a parent div, which is defined as a Sortable on page load. 3. There is a destination div on the RHS also. Sortable.create("div_leftDiv", {ghosting:true, revert: true, dropOnEmpty:true,

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''ve done === class HomeController < ApplicationController def index @country = Country.find(:all, :include => "cities") end end === And rhtml is: === <% @country.each do |country| %> <h1><%= country.name %></h1> <% country.cities.each do |city| %> - <%= link_to city.name, :action =>

Hi all, I''m sure I''m missing something obvious. I add prototype.js and my custom js file in the head: <script src="prototype.js" type="text/javascript"></script> <script src="my_js_file.js" type="text/javascript"></script> my_js_file.js looks like this: Event.observe(window, ''load'', loadTasks,

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

Hey Guys, I know this isn''t specific to scriptaculous libraries but it''s something that I''m exploring as I use the ajax functions in prototype. My application server is not rails but java and I was thinking of returning a javascript array in the ajax response. When I get back my response is it, of course, text and I''m not sure how best to convert it into

When using drag and drop, the browser window will not scroll if you move the mouse off the page. This makes it very difficult, if not impossible to create certain types of web applications. I know this has been mentioned before and is on the Wish List, but it''s very frustrating. If you look at this other Javascript library called "Drag''nDrop & DHTML Library"

I have been working on a project that involves a lot of front-end functionality and I noticed that Position.cumulativeOffset was not as accurate as I had expected/needed. I also needed some more options and I just didn''t really like having to type Position.cumulativeOffset all the time. I wanted to simply do element.getOffset() and be done. After lots of time spent going back and forth

Is anyone working on a scrolling table or div such as the openrico livegrid demo? I''m looking to develop (much like smashbox''s scrolling images) a collection of thumbnails that you can scroll horizontally. I''ve got a non-prototype.js example but I wanted to check to see if anyone was closer than I to this. BTW, I will be finishing up my slider code shortly and

I have a page where I am replacing a table element after the page has loaded. I get an error (on ie 6) when prototype.js calls cumulativeOffset. For the new table element, requesting the element.offsetParent property results in an "unspecified error" that brings my whole page to a crashing halt. Does anyone have any ideas or suggestions?

Hey Guys, I''ve just encountered this error in Firefox will I pulled the latest scriptaculous rc into project. Sadly, I don''t have a linkable page for you to look over at the point. My question is what is this error exactly? My code before this never got it but now it does. My few searches suggest it''s the browsers way of keeping infinite loops from happening

I''m trying to understand the Position object. Specially the various offset methods. From looking at the code I think I may understand them but I wanted to run it by the group to make sure I had a clear understanding. realOffset - This returns the coordinates of the element as if none of the elements on the page are scrollable from the document edge. cumulativeOffset - This returns

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?

It''s been a few days since I posted my last two emails (of which, no one replied to) so I''ve gone ahead and coded a working slider class as well as a ''resizeable'' class that allows a user to drag and resize the element. I also linked these two together as I want to have slider behavior that can resize the resizeable element. The end result is both the

I''ve been testing my page, which not only includes my new slider code but the drag and drop code as well. You can see it here: http://hoover.razorstream.com/preference.htm My issue is that in IE, I get the annoying security warning across the top saying ''IE has restricted this file from showing active content that could access your computer''.
