I have a few maintenance programs that run periodically via cron. I learned how to use rails model files in those apps w/o much problem. However, the problem came about when one of my models, then many of my models began using plugins. Now I find that with each new plugin I use in my models, I have to go back to each of my utility apps and specifically require that plugin in order for

Hi, Just wondering when one would use "include" over "extend"? Both seem to bring in methods to the class no? The context is I''m just trying to understand why both are used with the acts_as_audited plugin: Full extract from plugin (used within here): ================================================== # Copyright (c) 2006 Brandon Keepers # # Permission is hereby

Hello all, while I''m using acts_as_audited(on jruby platform), after vendored the acts_as_audited, it reports some error, line 167, # Start observing the declared classes and their subclasses. def initialize Set.new(observed_classes + observed_subclasses).each { |klass| add_observer! klass } #this line end after some trace shows this one, when observed_classes is empty, will

I hope I''m not breaching etiquette too badly. It''s not my intention to offend or pressurize anyone. Also, I admit my personal motivation. I had a look at the list of pending patches (http://dev.rubyonrails.org/report/3) to get an idea what patches are currently open and see what their state is. From some of my own patches I know that they are basically ready for either

I have a form below a table to add new notes to an item. If the note does not have a title or body, the note is not saved and a form error is displayed. However, if the note validates successfully, then the note is added to the bottom of the table above. Just for reference, the table id is "note_list" and the add form div is id="note_add_form". So, my problem/question

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 -

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

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

has anyone has any idea how to implement audit trail table for all update / deletion done on records? I''m thinking to have corresponding audit trail table to each table, so everthing before an update or deletion is done, a new record will be insert into the corresponding audit trail table. Is there a way to overwrite the save, destroy, method at the application level? so that I do not

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

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

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

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

Somewhere between 0.13.1 and the current SVN version the :overwrite_params option to url_for (and related methods) went missing. I can''t tell whether this was deliberate or by mistake, and I have no idea how to get the same functionality in some other way either. Michael -- Michael Schuerig Life is what happens

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

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 admit it, when it comes to rSpec, I''m lazy. I''ve made a few feeble attempts to use it, but for once I''m waiting for a book-length treatment. At least two books were announced, I think. Can anyone in the know please report on their progress? Thanks Michael -- Michael Schuerig mailto:michael at schuerig.de http://www.schuerig.de/michael/
