Hello there, This is my first post to the Ruby group. I am also new to the language and the Rails framework, it is an amazing place to be now. Coming from a PHP/ASP background I am glad something like Rails finally made it into web development. Now to my question. I have been readying a lot about AJAX, and I wondered what kind of support is built-in into Rails for it. I read somewhere that

I just knocked up a quick plugin based on Rafael Lima?s Javascript which was inspired by the Browser selectors in CSS post by 37signals. It?s pretty naive at the moment, but could be nice to build on in the future. It adds two helper methods available in your views - browser_is? and browser_name <%= browser_name %> => mozilla (or whatever) <% if browser_is? :mozilla %> do

Building on the great ''acts_as_versioned'' plugin by technoweenie, I''ve written a small plugin which also stores versions of associations. It''s early and experimental at the moment, but does work. For example: class Article < ActiveRecord::Base has_many :images has_and_belongs_to_many :categories acts_as_versioned acts_as_versioned_association

I''ve spent the weekend giving my acts_as_versioned_association (or version_association for short now!) some much needed attention. Unit tests have gone from a shameful 150 lines to well over 700 now - around 1:3.5 code to test ratio. There''s still probably a lot which needs testing, but it should be a lot better now. It''s a fairly major update and there are some

I''ve started getting the following error on Dreamhost when trying to run any scripts or dispatch.* [barry]$ ruby -d script/server Exception `LoadError'' at ./script/../config/boot.rb:6 - no such file to load -- pathname ./script/../config/boot.rb:6:in `require'': no such file to load -- pathname (LoadError) from ./script/../config/boot.rb:6 from

I''ve been testing the in-place-editor on a few things and it works well. One use-case I''ve just come across though is the need to load in the text from somewhere other than the source of the page. For example, I have a block of text which is marked up in texttile/markdown/whatever. Editing that block should bring up the unformatted markup, not the HTML it''s turned

I have the following 3 models (2 models joined by an intermediate): 1. class Exercise < ActiveRecord::Base 2. has_many :routines, :class_name=>''RoutineExercise'' 3. end 1. class Routine < ActiveRecord::Base 2. has_many :exercises, 3. :class_name=>''RoutineExercise'', 4. :order=>''position'' 5. end 1. class

Hi, has anyone come across any incompatibilities between file_column and login_engine? I''ve been having strange issues where a User model with file_column in it is failing to save the images properly. Everything uploads to the tmp dir fine, but then it never gets copied to the proper permanent location. No errors - everything happens fine except for that final part. I have

Does anyone have any experience with subscriptions and PayPal? I''m currently weighing up the options of what payment system to use for an upcoming project which is subscription based and am not sure if PayPal is capable of doing what I want and if I need to setup a merchant account instead. Basically it''s the same kind of payment structure as BaseCamp. 3 or 4 accounts which

I have a join table I''m creating with a migration as follows: create_table :read_global_messages, :id=>false do |t| t.column :user_id, :integer t.column :message_id, :integer end So far so good, however I want the primary key to be user_id and message_id. How do I do this? I tried the following, but that doesn''t work: add_index

As far as I can tell, it''s not possible to use html_options in conjunction with the select_* helpers. This means using them in conjunction with observe_field etc is pretty much impossible. Does anyone have a patch to add this functionality, or know of a workaround? I''m having a look at the moment, but not sure how to get it working without breaking existing stuff. --

I''m trying to do an IN query, where I have an array of user objects imaginatively named ''users'': :conditions=>["user_id IN (?)", users.collect{|u| u.id }.join('','')] this ends up with: ... IN(''1,2,3'') ... Obviously I want this to be: ... IN(1,2,3) ... or even ... IN(''1'', ''2'',

In the customized autocomplete demo, how does it know what content to use as the value of the autocomplete? The returned UL has the name, email address and an image. Yet only the name is used. How does it do this? I''ve been trying to get something similar going all morning with little success. Also, what does :skip_style=>true do? I couldn''t seem to find a mention of it

Having a bit of an issue with url_for The current page I''m on has a named route as follows: map.some_page ''page/:id/:range'', :action => ''the_action'' All looks fairly normal. I have an url_for on this page to make a link to another page as so: url_for(:controller=>''other'', :action=>''display'', :id=>5,

I have a number of timezone related issues which I''m currently confused about. I want to store all times in the database as UTC/GMT so that I can then massage them to be displayed how I like at a later date. I''m using the TZInfo class at the moment to convert timezones and to deal with daylight savings time. My main question is how do I ensure all data is stored as UTC when

When a sortable has ''ghosting'' enabled, it seems to include the dragged element twice in the list which is submitted in the onUpdate AJAX request. By the looks of it, it''s appended onto the end of the list when Sortable.serialize is called. IE in the following list: - 1 - 2 - 3 If I drag 3 to be at the top, what we expect is: [3, 1, 2] What we get is: [3, 1, 2, 3]

I sent this on Friday but somehow managed to email it to the wrong email address! ---- Attached is a patch to add external (AJAX) loading of content to the InPlaceEditor. 2 extra options have been added: loadUrl: a URL to load the content from. If this is present, it will be used instead of the innerHTML. fieldId: I had to add this so we know what the text field is when we''ve

I''m trying to use file_column in an app I''m writing. Simple file uploads are working fine. However, when I try and use the :magick options to make resized versions, WEBrick dies. This is the Media model: class Media < ActiveRecord::Base file_column :media_item, :magick => { :versions => { :thumb => {:size =>
