I'm handling file attachments in my Rails app with Attachment_fu, which provides a public_filename method to retrieve a file's URL. I'm using it on a model called Cover, so if I want to call the URL of an uploaded cover image, in a view I would do: <%= image_tag(@cover.public_filename) %> This works just fine when the user has the app...
I have a model which gets its data from a parser object. I'm thinking that the parser class should live in the lib/ directory (although I could be persuaded that it should live soewhere else). The question is: Where should my unit tests for the parser class be? And how do I ensure that they are run each time I run rake test? ...
I'm working on a fairly traditional forgot password email - I want to email the user a password change token embedded in a link that they can click on in order to change their password. I'm emailing via the traditional ActionMailer. If I use a normal link_to tag <%= link_to "click here", :controller => foo, :action => 'bar', :token =>...
Since Rails is already an effective Rich Internet Application framework because of the way it makes Ajax so easy, what is the argument for combining Rails with Flex and using Flex as the front end instead of HTML? A programmer friend of mine said he uses this combination because Flex is great for RIAs. My argument is that Rails is alread...
Trying to get along with Sphinx/Thinking Sphinx for the first time. I've got my models defined as follows (simplified): class Branch < ActiveRecord::Base has_many :salesmen, :class_name => "User" has_many :leads, :through => :salesmen end class User < ActiveRecord::Base belongs_to :branch has_many :leads, :foreign_key => "ow...
I am having issues getting a workling daemon working correctly. When I run: ruby script/workling_client run the daemon starts to load rails, but hangs indefintely. When I kill the process, the stack trace is always the same: /Library/Ruby/Gems/1.8/gems/activesupport-2.1.2/lib/active_support/core_ext/load_error.rb:32:in `new': Interr...
What does that mean? In the instructions for a project, it said to "freeze the Rails gems". Is that different from freezing the Rails version? What's freezing about? ...
I'm trying to display a javascript feedback widget in my default application.rhtml in a rails app. It will only appear on a subset of pages, distributed across different controllers. Trying to figure out the best way to do this. One thought was to do something like this: <%= render :partial => "layouts/feedback_tab" if @show_feedb...
Hi. I'm building a website for my Web Dev class, and I'm stuck on rendering HTML. I want to be able to use a simple form (Pretty much all I have right now is a scaffold for this controller, and I attempted sticking a content_type into my controller, but no progress.) to submit text and have it rendered as HTML. The idea is that, since th...
I have a rails app that uses two of the same models as another rails app I have. What's the best way to keep data synced between two models? MySQL replication probably won't be possible due to hosting restrictions and since stuff that references the replicated data is dependent => :destroy meaning mysql replication will cause stuff tha...

Hi, Wanted to know if someone had a suggestion on code or maybe there's a plugin (!) which would allow very basic forum functionality that I can integrate into my application so that it is single sign-on? Otherwise...maybe a tutorial on how to build one from scratch and I just leverage our existing authentication? Thanks! I looked at...

I want to obtain an array of ActiveRecord objects given an array of ids. I assumed that Object.find([5,2,3]) Would return an array with object 5, object 2, then object 3 in that order, but instead I get an array ordered as object 2, object 3 and then object 5. The ActiveRecord Base find method API mentions that you shouldn't expect ...
I have a field called sui in one of my models. It stands for "Standard User Identifier." When there are validation errors on the field, Rails prints "Sui is required" or "Sui is already taken." How can I tell Rails that 'sui'.titleize is "SUI"? I looked at Inflector.human, but that isn't quite right. ...
Right now I have two fields for cost. One for dollars and one for cents. This works, but it is a bit ugly. It also doesn't allow the user to enter the term "free" or "no cost" if they want. But if I only have one field, I might have to make my parser a bit smarter. What do you think? On the server side, I combine dollars and cents t...
In my blog application, some posts appear as excerpts -- i.e., the user sees the first (say) 500 characters, and can click a link to view the entire post. Here is the relevant partial: <% href = url_for post_path(:id => post) %> <h1 class="title"><%= post.title %></h1> <h2 class="published_on"><%= post.author %> wrote this <%= time_ago...
I have an application with a lot of database relationships that depend on each other to successfully operate the application. The hinge in the application is a model called the Schedule, but the schedule will pull Blocks, an Employee, a JobTitle, and an Assignment (in addition to that, every Block will pull an assignment from the databas...
