Hey everyone, I''m interested in extending ActiveRecord::Base. I have a special "easier" find function that I want to include in all classes. How can I include this in all classes? Can I just create a model object that does something like this: class ExtendedAR < ActiveRecord::Base def self.special_find ... end end and then all my other classes

I have several tables for enumerations. They all have the same content: id, name, position. I''d like to avoid the tedious work of defining a class for each one explicitly. Not least, in order to avoid clutter in the model directory. Here''s what I''ve come up with: class EnumRecord < ActiveRecord::Base def self.define_enums(*enums) enums.each do |spec|

Hi everyone, I''m building an app in RoR that apart from the normal web interface has a web service. This web service takes a parameter and uses that in a single database query, and returns the result in a simple XML format. This web service needs to be quite fast as it will be used on all pages of a quite big site with thousands of visitors every hour. I don''t think caching is

I''m in a dilemma: In order to keep GET requests from deleting objects, I''d like to use the button_to helper to get "something" that generates a POST request. Unfortunately, that something is a form and forms can''t be nested. I''d also like to place buttons related to the same form close to each other. At the top are some navigational buttons

Some of my earlier questions may have hinted ever so slightly in the direction that I''m trying to implement "enumerations". By an enumeration here I mean a class that has a fixed number of immutable instances, which in turn have essentially only a name and a position. Requirements I''ve tried to meet are - Enumeration instances should only be loaded once from the

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 know there''s wiki page on generating PDF[*], but that''s not really what I want. I don''t need to create arbitrary PDF. What I''d like to do is create PDF templates and fill in the blanks. Roughly, I''m looking for functionality akin to the mail merge feature of word processors, including conditional and repeated elements, say, table rows. Michael

I have a model layer containing Movie, Person, Role, and RoleType, making it possible to express facts such as "Clint Easterbunny is director of the movie Gran Milano". The relevant model and associations look like this class Movie < ActiveRecord::Base has_many :roles, :include => :role_type, :dependent => :destroy has_many :participants, :through => :roles, :source

Hi! Say we have a rails active-record-based model called "instance" which can have different states - STOPPED, RUNNING, STARTING_UP, SHUTTING_DOWN, etc... There is a method #start which changes the instance state to STARTING_UP only if it is STOPPED. def start if self.state == STOPPED self.state = STARTING_UP self.save ... end end As you understand if we have multiple

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

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

This is OT but have not been able to get a response elsewhere (stack overflow and the project site itself) so thought someone here might know or have some ideas. First, I am using wkhtmltopdf stand alone without any of the rails gems as I found that for some reason using WickedPdf or PdfKit my pdf''s did not generate with active links from the links from those in the html. When I run

When a validates_asssociated fails... I get something like Address is invalid is there a way, preferably on a per-association basis to have the error messaage include the actual error like Zipcode is too long (max is 10 characters) _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org

Hi, I found it a while ago, an add-on to Rails for supporting movable select boxes, but I searched through the wiki and the mailing list and couldnt find what I was looking for. I was hoping someone might know of or remember something about the project. Thanks, Dylan.

There really doesn''t seem to be a *declarative* way to define a default value for belongs_to and has_one associations class Person < ActiveRecord::Base belongs_to :address end p = Person.new p.address.city = ''Atlantis'' # Bummer! Of course, there''s an easy way to avoid this class Person < ActiveRecord::Base belongs_to :address

All I realise that this isn''t strictly the correct place to discuss the prototype lib but being as scriptaculous is dependent on it I thought people might have some opinions. Easier to explain with the example below, copy into a html file and ensure the path to prototype.js is correct. You''ll see the first example prints an extra element "extend" when iterating over

Hey guys, I realized some people have had problems with nested controllers and the :overwrite_params call. The way I fixed it is like this: :overwrite_params=>{:controller=>"/#{params[:controller]}"} I would love to see if other people could improve on this, its not the prettiest thing. -- Posted via http://www.ruby-forum.com/.

Currently, pages generated by Rails tend to be sprinkled with JavaScript. This happens, because the various helper methods work only locally and simply append to the output. In order to hide the JavaScript away, rendering would probably have to be changed. A way I can think of is that a page-specific script is included in the head of the document and JavaScript code is not written to the

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
