I've installed paperclip to my project as plugin using ruby script/plugin install http://github.com/thoughtbot/paperclip.git Model: class Company < ActiveRecord::Base has_attached_file :logo, :styles => { :large => "300x300>", :medium => "100x100>", :thumb => "50x50>" } validates_attachment_content_type :logo, :content_type => im...
Hi, I'm calling a rails app from another using ActiveResource. I need to supply the id of the new object to the first app (yes, controller create in this app knows how to handle receiving an id), so I do something like this: a = ActiveResourceModel.new(:id => 1231231, :name => "test") a.save However, instead of doing POST to create a ...
ActiveRecord use to call after_save callback each time save method is called even if the model was not changed and no insert/update query spawned. This is the default behaviour actually. And that is ok in most cases. But some of the after_save callbacks are sensitive to the thing that if the model was actually saved or not. Is there a...
I was wondering if there is a nice pattern or better yet a specific function which applies a function until there is no longer a change in it's result. url = "http://www.zzz.com/yyy/lt%255B1%255D.jpg" unescaped = unescape(url) while unescaped != url do url = unescaped unescaped = unescape(unescaped) end Although the code above is ...
I'm trying to click the Settings button on the home page, but when I do I get this page back: #<WWW::Mechanize::Page {url #<URI::HTTP:0x1023c5fc0 URL:http://www.facebook.com/editaccount.php?ref=mb&drop>} {meta} {title nil} {iframes} {frames} {links} {forms}> which is.. kinda empty!

On Windows, how do I check to see if an authenticated user (ex: DOMAIN\User) is a member a local or domain group with Ruby? In this case Ruby is running on Windows Enterprise Server 2003. ...
Hi folks, I've the following code in a _form.html.haml partial, it's used for new and edit actions. (fyi I use the Ryan Bates' plugin nested_form) .fields - f.fields_for :transportations do |builder| = builder.collection_select :person_id, @people, :id, :name, {:multiple => true} = builder.link_to_remove 'effacer' ...
A little background: I've written a script that will act as a receiver for incoming Syslog/Email/Snmp(v1) traps. It receives the data and stores it as a custom defined object. My "messageSocket" is a means to control the behavior from a script outside of this general listener. I want to send messages to this to either start/stop on ...
I'm a bit confused as to how "relationships" are created/processed in ROR/rake. Can anyone confirm if the following is correct? Code the "insert xxx relation" in the DB Migration file. Migrate this once done. Code in the final relationship (has_xxx...) in the model file. If so, can ROR autogen the DB Migration file from changes in t...
This works, but it was a stab in the dark. I know little Ruby. What's the accepted way to serve a plain old file for a given resource? get '/xyz' do File.read 'abc.html' end ...
I want to learn Sed. Can you please point me to good references so that I can fully utilize it. I want to learn it to perform more of the do-once-then-forget type administrative or dev-tools like tasks. So, I don't really care about performance or modularity or object orientedness etc when writing this type of code. Do you think it wou...
I can't work out from looking through the source what the difference is between the cattr_* and mattr_* methods provided in Class and Module respectively. I read this question: http://stackoverflow.com/questions/185573/what-is-mattr-accessor-in-a-rails-module which gives some details about both methods but doesn't highlight the differenc...
I'd like to make a website, it's not a huge project, but I'm a bit out of the web design loop. The last time I made a website was probably around 2002. I figure the web frameworks and tools have come a ways since then. It's mostly the design aspect that I'd like it to make easier. I can do the backend language in any language. My qu...
I'm trying to make a method similar to attr_reader but I can't seem to get the instance of the class that the method gets called in. class Module def modifiable_reader(*symbols) # Right here is where it returns Klass instead of #<Klass:0x1df25e0 @readable="this"> mod = self variables = symbols.collect { |sym...
In IRB if I pass a string like "/domain/path" to Regexp.escape it just returns it the same. I thought that forward slashes are supposed to be escaped with a backslash? Am I missing something here? ...

Hi, I want my rails app to accept dates for a date field in the format dd/mm/yyyy. In my model I have tried to convert the date to the American standard which I think the Date.parse method that Rails will call on it is expecting: before_validation :check_due_at_format def check_due_at_format self.due_at = Date.strptime(self....
I have a model, let's say Attachments, that uses attachment_fu to accept file uploads from the user. I want to "deep copy" (or in Ruby-ese, deep clone) an Attachment, thus creating a completely new binary object in the "db_files" table. I've found that it is not quite a solved problem yet. This blog posting: http://www.williambharding.c...
In Ruby 1.8.7 I can do the following in order to get the subject of a binding object: binding.eval("self") However, in Ruby 1.8.6, the eval method is private, so I expose it like this: class Binding public :eval end Which seems to work fine, however, binding.eval("self") returns the binding itself, not the subject of binding. Ho...
I'm using Ruby+Watir to request pages through Firefox. I would like to record the headers and content of every http request made through the browser. Would it be possible to configure a proxy solution to store this information, either in a file or pipe it straight into an application? Could I use something such as squid or nginx to rec...
