I am trying to use link_to_remote to simply add a record to a database table called "ratings". I''ve seen some examples of this being done but can''t seem to get it to work. Any ideas about what I''m doing wrong? Here is what I have in my view: <%= link_to_remote( "1", {:url => { :controller => "ratings", :action =>

I''m trying to implement acts_as_rateable to my Beast installation to give users the option to rate posts (like reddit). I chose acts_as_rateable as it supposedly easily allows reddit-type voting but I''m having some problems setting it up and the documentation seems outdated. (http://www.juixe.com/techknow/index.php/2006/07/05/acts-as-rateable-plugin/) So far, I''ve

I''m trying to validate a record before save. I''m using one controller in this case furnii where I have all my calls. The problem is that, the form containing the field I''m trying to validate resides in the furnii views. I tried to add validates_presence_of :content (the field name) in both the furnii model and the ratecomment model but it does not work. I know there

If I have several models which exhibit the same functionality, it seems makes sense to create a mixin, ''include'' it in each model and save myself some work and repeated code. Where can I define a module which will be available to all models? I can''t seem to find a documented place for them. Alternatively, is there a Rails-standard way of achieving the effect? Ben

Disclaimer: RoR newbie. Using the acts_as_taggable plugin. As an exercise I wanted to switch from the destructive TAG_WITH method to adding tags while preserving the existing ones. On the surface this seemed easy enough and eventually I got it working. However, the following method: def add_tags(list) Tag.transaction do Tag.parse(list).each do |name| if

so as to not reinvent the wheel, are there any exisiting examples or mixins for a star rating system? basically what i''m looking to do is show pictures of local models which will be voted on by users, and the model with the most votes will get her photo in a calendar. anyone able to point me in the right direction... tutorials, code, whatever would be greatly appreciated! -A --

I want to include common auditing functionality in my models. This involves storing the changes made to a model in a seperate table : I have created the functions in an Audit module : module Audit before_update :before_changes after_update :after_changes def before_changes old=self.class.find(id).attributes @changes=[] attributes.each do |key, val| if val != old[key]

I''ve created an access control module that I''m including in several different controllers. Everything works fine, but I want to allow each controller to override the default login page with something like this: set_login_pages :secure => ''my_login'' In my module, I''ve set up the set_login_pages method like this: def self.included(base)

Hi, I just put together a little mixin to provide pseudo-RESTful services in camping apps. Basically, it looks for a hidden _verb field in form posts, and sets the @method to the supplied value (e.g. put or delete - which browsers don''t support). This lets you define put and delete methods in your controllers. Groovy. Code: http://pastie.caboo.se/22613 Is there any permanent repo of

It seems to me that Validations are quite useful for many objects, even ones having nothing to do with ActiveRecord. Common examples are Contact Us forms, multi-step forms, web service paramater validations, etc. I took a look at the source for Validations, and it seems that it is very independent from ActiveRecord. I caught only three depenedencies: 1. validates_numericy --> depends on

Hello everyone. I am not sure if this is the right place to post, please redirect me if there is a mailinglist more specifically dealing with prototype.js. After playing around with the very inspiring prototype library I have found a rather annoying thing, that makes the usefulness of the Enumerable mixin for Hashes questionable, if I am not totally wrong (again :-). Here an example:

Hi! Definite newbie here - I''m working through this like-hate relationship with Ruby and Rails right now... sometimes things work really well (like blobs seem to rock) but other times, I dunno! :-) Anyway, I''d like put in create and update user timestamps on all my primary domain tables and allow them to be updated automatically by ActiveRecord. Coming from Hibernate, I just

Starting to feel more confident and code is DRYing up nicely, but I''ve hit a brick wall here and hoping someone can help me. I''ve got a module, TrustRanking, which extends a number of model''s instance methods, and I want to extend their class methods too, but I can seem to work out how to do it. Simply including the module from the class works a treat for the

Hello At the start of October, Duane Johnson announced the Query mixin plugin on this list. The code was attached to the announcement email. Unfortunately, I''ve not been able to locate the attached code. Goggle has not helped me this time. Could somebody forward it to me? Thanks in advance Harvey This e-mail has been scanned for all viruses by MessageLabs.

Dear Professor Fox, Apologies for my oversight relating to the polychor command and thank you for your advice. I turned to the polychor command when trying to find an equivalent for the polychoric command found in the psych package (I am following a procedure outlined in Gadermann, Guhn & Zumbo, 2012 that uses this command rather than the polycor package) . The polychoric command is returning

If I want to write a function which will be available to views, I write a helper function in one of the places set aside or that very task by Rails. If I want to write a little suite of functions to be mixed in by a number of model classes (but not all), where do I put them? Plug-ins look like AN answer, but they also seem a little heavyweight for simple, project-specific tasks.

Hi guys, in development mode a module mixed into a helper class seems not to be reloaded inside app/helpers: class TestHelper include EvenMoreHelp #foo end module EvenMoreHelp # bar end the contents of #foo get refreshed, but not #bar... is there a way to fix that behaviour. I intend a full reload in development mode for obvious reasons. Regards Peter

I''ve been working on a plugin called Http Test where I add HTML validation and link checking to controller and integration tests through an after filter in ApplicationController. I used to mix in a bunch of methods that I needed into the ApplicationController class, but to me this had a bad smell, so I broke much of the code out into separate classes that I delegate to.
