Hello again: I''m hoping that somebody, anybody, can help with this question. How do I make sure that records in a join model are unique? Using the scenario outlined in Chad Fowler''s "Rails Recipies", number 16, "Many to Many Relationships Where the Relationship Iteself Has Data". Here are the tables: create_table :magazines do |t| t.column :title,

The validation reflection plugin adds three things (1) Reflective access to validations - ModelClass.reflect_on_all_validations - ModelClass.reflect_on_validations_for(:property) (2) It provides "declarative" methods for defining validations based on database metadata - validates_presence_of_mandatory_content_columns - validates_lengths_of_string_attributes -

Ah - thanks Michael. Event.stop is precisely what I was looking for. I can just grab the event object inside the handler that I registered previously and pass it to an Event.stop call, and get exactly what I want.

Recently, I''ve started to write unit tests for some of my scripts. In general,it''s no worse in JavaScript than in Ruby or Java. I didn''t have the courage to try Selenium, but had a look at JsUnit. Unfortunately, in Konqueror it produces unfathomable errors and in Firefox it is slow beyond imagination. Anyway, writing tests for functions that are computational or

I''m in the process of updating an app for Rails 3.0 and rspec-rails 2.0.0.beta20. When I''m running my specs (rake spec) I get a large number of errors caused by two undefined methods undefined method `has_selector?'' for #<String:0x7fdbd0b5b270> undefined method `flunk'' for

[I sent this already two days ago, but apparently the message didn't get through. It is not in the archive either.] I've read through the Programmer's Manual, Language Reference, and Kaleidoscope Tutorial, still I'm struggling to get started hands-on with LLVM. This may just be a passing phase and I'm in no hurry, so I'd like to take the time to read up some more on

Has someone come up with a generic way to handle ajax requests that exceed a certain time? In my concrete case, I have several select boxes for drilling down a hierarchy. When the user clicks an option, the next deeper level is retrieved. To avoid multiple concurrent requests, I disable the select box. As the request may take too long or cause an error, I set a timeout that re-enables the

The attached patch transparently extends the Builder from util.js to take an object/hash value for the style attribute. The elements of the hash are then used to set the respective properties of the style object. The purpose of this patch is twofold: (1) Make it easier to use the Builder with generated style properties. (2) I''m not sure if assigning a string to element.style is even

Thomas, currently the script.aculo.us scripts have some workarounds for Safari that should be extended to more generally cover all khtml-based browsers, Konqueror in particular. In prototype.js, there is a workaround for an addEventListener bug that affects Konqueror as well as Safari, controls.js has a similar workaround, and the special case in dragdrop.js doesn''t hurt anyway. In

I''m no friend of paging, but I have to somehow deal with lists of potentially large numbers of objects. The Rico LiveGrid[*] at first blush seems attractive, but has some major drawbacks. It doesn''t work with Safari/Konqueror, not yet anyway. It can only handle fixed-size tables and requires that widths, including column widths, are hand-crafted. I''m looking for a

It''s awfully quiet in here... So here''s another bunch of scripts that are heavily inspired by Prototype.js and useful in conjunction with Rails http://www.schuerig.de/michael/javascript/ Please have a look... at the code. There''s nothing visual about the scripts, I happily leave that to Thomas. Michael -- Michael Schuerig Airtight arguments have

Prototype.js and Thomas''s effects scripts use repeated setTimeout calls for timed looping, for instance in time-based observers. On Konqueror 3.4.1 (possibly other khtml-based browsers, too), these observers reproducibly crash the browser. Just keeping open a browser with such an observer is enough. After some time it invariably segfaults. When I substitute setInterval for setTimeout

JavaScript doesn''t (yet) have a notion of classes. Prototype.js just adds a suitable convention for implementing them. It provides a way to create a new class by extending a base class using Object.extend, but it doesn''t handle method inheritance. There are ways of doing implementing this through traversing the chain of prototypes, but I''m not sure they are

I''ve noticed that using several TimedObservers (prototype.js) on a page to watch for changes to text fields (haven''t tried forms) can have a non-negligible effect on the CPU cycles used by the browser process. Nothing dramatic, to be sure, but unnecessary. Autocompleter.Base (controls.js) follows a smarter strategy to watch for changes. Currently this functionality is tied

What: The original scripts in llvm-top assume that they're dealing with a subversion working copy. The patch adds support for a git repository cloned using git svn. The other two patches make llvm (core) do an out-of-tree build, i.e., the source tree is kept clean, and tells llvm-gcc-4.2 to find llvm in the right (new) place. Why: Using git it is possible to fiddle locally with the code,

I''m in the progress of packaging some stuff I''ve written as plugins and I''d like to host the plugin code in their own project repositories at rubyforge. My preferred way of writing a plugin is as part of an application, i.e., my working copies of the plugins live in the vendor/plugins directory of a rails app. Of course, this rails app is version controlled in my

I just found this (by way of comp.lang.javascript), and article on the use of and reference for prototype.js. http://www.sergiopereira.com/articles/prototype.js.html I haven''t checked the details, but it looks pretty good. The author points out that it is un-official. Sam, if you''re reading this, is there a chance of giving it an official blessing? Michael -- Michael

I''d like to finally get started with RSpec, however, not on a complete (rails or whatever) application, but only on a single rails plugin. In particular, I want to test the plugin without the context of a specific rails app. The only parts of rails that I need are ActiveRecord and ActiveSupport. It would be very helpful to have an existing plugin that''s tested like this as

Yehuda has a nice article on implementing a custom renderer for PDF at http://www.engineyard.com/blog/2010/render-options-in-rails-3/ I''ve tried to follow the example and I''m not sure I see how to get it to work. If I understand things correctly, the format(s) usable in this render call respond_with(@resource) do |format| format.xyz { render :xyz => ... } end
