similar to: Introspecting validates_presence_of

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

Hello all. I don''t know how to get all symbols passed to method validates_presence_of in model. I''ve trying to use following solution: class News < ActiveRecord::Base validates_presence_of :title, :text def validates_presence_of(*attr_names) @@obligatory_fields = attr_names ActiveRecord::Base.validates_presence_of(*attr_names) end def obligatory_fields

What''s the page.method to change the background color of a DOM element? I''m trying to change the background color of a couple of styled <li>''s when an Ajax link is clicked.

Hello, I'm wondering if the following situation is valid (though I think it isn't since I still cannot authenticate with ldap pass/userdb on test67 running on FreeBSD-5.3). Is it normal that the passdb_ldap_conn->attr_names second element (for instance) "turns to" "homeDirectory" as the following step by step gdb run sample shows ? : -- Breakpoint 1,

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is

Hi list, is it possible to check if form field will be required when form is submitted (through validates_presence_of or some other validates_* method)? I could do this manually but it doesn''t seems to me very DRY. For example, I would like to be able to dynamically add asterisk with some helper method if city is required here: City*: <%= text_field

Hello, I've been trying to figure out what's wrong with authentication against an ldap pass/user db with test67 as test62 was working fine. [ The problem is the same as previously described in this list : - FreeBSD-5.3 - dovecot-1.0-test67 - openldap-2.1.27 --> "ldap(dovetest,127.0.0.1): No password in reply" --> "NO Temporary authentication failure." or --

I want append custom query parameters to my pagination links, like ?page=1&foo=bar. I can''t quite figure out how to do this with the pagination_links helper, although I believe the API says you should be able to: pagination_links(paginator, options={}, html_options={}) options are: :params: any additional routing parameters for page URLs Has anyone tried this? thanks, jeff --

Hi, I had successfully set up dovecot-1.0-test62 + ldap pass/user db, but now I'm encoutering a SIGSEV problem with a similar set up of a brand new dovecot-1.0-test65 installation. The auth process is killed by a SIGSEV as reported in the error log file : dovecot: Mar 30 17:06:59 Error: child 28291 (auth) killed with signal 11 To be precise, the problem occurs in the

Don''t get me wrong, JavaScript/Ajax helpers in Rails are a huge timesaver and they have helped me to finally overcome my irrational aversion to js libraries like prototype and such. However, all this goodness seems to come at quiet a price. The resulting code is littered with inline JS, including ubiquitous script tags and onload attributes etc.. It seems that just when i found

In a Rails controller I set the scope on a model class in an around filter. I have defined expectations on the model classes, and ideally, I would add a further expectation for the scope. Is this already possible in some way? How would I go about adding support a scope expectation? Michael -- Michael Schuerig mailto:michael at schuerig.de http://www.schuerig.de/michael/

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

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

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

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 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

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 -

Has anyone had any luck using the CalendarHelper plugin at http://wiki.rubyonrails.com/rails/pages/CalendarHelper recently?
