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''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

Here are a couple of articles I wrote describing a couple of handy helpers for dealing with polymorphic objects. These helpers allow you to generate urls and render partials on objects without knowing what class they are ahead of time. http://www.sciwerks.com/blog/2006/05/24/polymorphic-urls/ http://www.sciwerks.com/blog/2006/05/24/polymorphic-partials/ Hopefully you will find them useful.

Has anyone tried to create a tri-state or multi-state checkbox control for rails? What I''m looking for is a control that will cycle through a series of states when clicked.

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

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

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.

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

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

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

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/.

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 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"

This forum has been a great resource for me. It would be great if i can search the forum before posting any question, as i''m sure someone has already posted that question before. The search function has been disabled for quite sometime now. I''ve already emailed the administrator but haven''t got any response. any idea on when this would be enabled ? Thanks, VASU.

I am having a problem with ruby''s sort_by function. I want to sort a list of parent model objects based on the children of the parent models. Normally you might say sortedList = modelList.sort_by { |model| model[''someAttribute''] } What I am tring to do is sortedList = modelList.sort_by{ |model| model.children.find(:first, order=>"price desc" ).price}

Hello. Using the ":include", which generates a "LEFT OUTER JOIN" SQL command, it is possible to eagerly preload second order data objects (children) for a given association. I wanted to know, if it is possible to eagerly preload and cache third order (or more) data objects, which are little-children or little-little-children. As I''ve seen. it is possible to add
