similar to: plugins and testing

I''ve set up a couple of STI models like such that we get something like this... class A < AR:Base class B < A acts_as_taggable class C < A acst_as_taggable (using the acts_as_taggable plugin) I can tag things just fine this way, the problem I encounter is that the taggings are listed with the base class ("A") and not the appropriate subclass ("B"

Is there some standard way to test migrations? It seems to me that an additional safeguard for migrations would be to test and see if applying the migrations to the test database allows one to reconstruct the structure of the development database. If you can''t, then there is an error in your migrations, most likely because someone hand-modified the database without generating a

I''ve got a couple of helper functions in my application_helper file that I would like to run from the console (for debugging). What is the correct way to invoke a helper from the console? _Kevin -- Posted with http://DevLists.com. Sign up and save your mailbox.

Running into an interesting problem that at first glance appears to be a bug in the AR association code. However, it''s explicitly coded this way so I''m not so sure. I have some code like this: class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end class Person < ActiveRecord::Base has_many :addresses, :as => :addressable,

This isn''t really a scriptaculous question, but it might be interesting anyway. I''m generating a rails app and in one form I have a grid of check-boxes (rows = A..H and col=1..12). I would like to put a checkbox in the column/row headers to toggle the boxes in a particular row or column. Each box has a name like ''position_A1'' or

RJS templates are nifty. They let you put all sorts of fun effects all over your bland html pages without too much work. The link_to_remote function also lets you run scripts before, during, and after an AJAX call is run by using callbacks. There does not seem to be an equivalent method for running an RJS template before or during an action. Rendering it at the end is no problem. One

Announcing RJSCallback 0.1 The RJS Callback plugin is being developed to provide Ruby On Rails with the ability to easily call RJS templates for the various callbacks associated with AJAX function calls (e.g., :before, :loading, :complete). Currently this plugin automatically detects, loads, and renders RJS templates with specific names and inserts them in the appropriate spot in

I''m curious to see how others are dealing with the construction of multi-page forms. I can see a couple of ways to do this, each with their own advantages/disadvantates. Approach 1: * define one table with columns for each form entry. * define a method/view for each page, which only displays a subset of the fields. * submitting a page saves the data and moves on to the next page.

I''ve been trying to use the ez_where plugin to create a dynamic finder. The structure looks somehing like this.. === controller === def list attribute_filter = params[:filter] @filter = Caboose::EZ::Condition.new :table do attribute <=> attribute_filter if attribute_filter end # ... do the find with the @filter # end === view === .... <%= link_to

Consider this problem. I have an Item that has_many Features I want to find all Items with a Feature name of ''foo''. Normally you would do this.. @items = Item.find(:all, :conditions=>["features.name = ?", ''foo''], :include=>:features) This all works fine and dandy except for this problem. If you do this... <% for item in @items %>

I''m creating an AR object in my controller and then attempting to add error messages to it: if (master_storeids.nil?) @item.errors.add_to_base ''No store is selected'' end This works without error but when it comes time for AR to add the record, it apparently initializes the errors because the message that I added does not cause the AR add to fail as you would

I''ve got an action in my application controller that needs to call a shared RJS template. Typically it''s actually being called by subclasses of the application controller. I''ve tried this.. def action ...code.. render :partial => "shared/template" end with ''_template.rjs'' existing in the shared folder. The problem that crops

Hello, how can I check if a destroy was successful? Is the object only frozen if deleted or do I have to do an additional find to see if there is a record left? What happens if an after_destroy callback returns false? Is there always a rollback? Markus

Hello everyone, I am needing to resolve an error on sqlserveradapter revolving around a trigger on a table. When the AR object is saved, AR throws Cannot create new connection because in manual or distributed transaction mode. at from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/connection_adapters/abstract_adapter.rb:88:in `log'' In order to resolve this, I

As part of an application I am developing, I have been delving into the dark art of Rails testing. Since the existing literature on the topic is a bit sparse, I have written up a couple of brief articles on testing strategies for rails. The first one is on the usefulness of ''Positive and Negative Controls'', and the other is a simple way to make sure you are working with

I''m using the acts_as_taggable plugin for Rails, and trying to set a breakpoint within it to examine behavior. While breakpoints work just fine in my main application, execution is never halted for the breakpoint in the plugin. Are breakpoints intended to work in plugins, or am I trying to use an unsupported feature? Thanks guys. John -- Posted with http://DevLists.com. Sign

In honor of RailsConf, I''m releasing an authorization plugin with 3 test apps that show you how to use the system. A reasonably lengthy description can be found here: http://www.writertopia.com/developers/authorization I will also be talking about the plugin''s architecture in my RailsConf talk on Saturday. Some features: - Nice English-like way of expressing permissions through

Hi, Just get started with Rails and I''m trying to read ahead and find out whether Active Record supports auto-creation of database tables for you? Is this supported, or is the concept that you write your own database DDL to do this? Thanks -- Posted via http://www.ruby-forum.com/.

Gents, I''m using the acts_as_taggable rails plugin (not gem), and would like to add some additional methods to it. For example, the find_tagged_with methods essentially does a find tag in a list (effectively an OR), while I''d like to implement a find_tagged_with_all method that would implement an AND (so if I specified 4 tags, it would only return items that were

Hi, I would like to be able to dynamically (without reloading the page) change the values from one listbox when a user select items from another listbox. I have a model ''Sector'' which has_many ''levels'' (and of cours, ''Level'' beyong_to ''sector''). I want to show the user two listboxes with the sectors and levels. But
