I have user entries as filenames. Of course this is not a good idea, so I want to drop everything except [a-z], [A-Z], [0-9], _ and -. For instance: my§document$is°° very&interesting___thisIs%nice445.doc.pdf should become my_document_is_____very_interesting___thisIs_nice445_doc.pdf and then ideally my_document_is_very_interest...

Hi, How is it possible to generate an absolute link to the javascript file. I assume there should be something like the one below (which unfortunately does not seem to be available): javascript_url 'main' # -> 'http://localhost:3000/javascripts/main.js' instead of: javascript_path 'main' # -> '/javascripts/main.js' I need the a...

Sometime back in a blog or in podcast I heard about a rails plugin that takes care of everything you need to worry about launching the site. The webpage will capture the email address of people visiting the site before the launch. And , I think, it also integrates with madmimi to send out emails to those people. I am not able to recall ...
Is there any way to prevent ActiveRecord from issued a SHOW FIELDS to the database when it's not needed? I'm working on database performance critical application, and just noticed that on a typical query my SELECT takes 0.5 ms and the related SHOW FIELDS takes 2 ms -- 4 times longer!

The point here is to browse the array docfiles and return two arrays (temporary_file_paths and temporary_file_names). I decided to return a Hash, but I feel I could get rid of the 2 temporary arrays but I'm not sure how... def self.foobar docfiles temporary_information = Hash.new temporary_file_paths = [] tem...
I am currently using nested model mass assignment on one of my models. It works a treat, however, I'd like to be able to ensure that any nested models that are created "belong_to" the same user. I've managed to implement this by using alias method chaining with: def contact_attributes_with_user_id=(attributes) self.contact_attrib...

I've been working on learning to use Rails the last couple days and I've run into something that I haven't been able to solve with Google. So I'm just creating a basic contact form that sends an email. Everything seems to be working ok in testing, which tells me that the form is working, and ActionMailer was implemented correctly, howev...
I have a user model that checks to see if a value has changed before_save (by running User.zipcode_changed?). The idea is that this will queue up a delayed job if it has. Problem is, when I migrate the app from scratch I get an error: An error has occurred, all later migrations canceled: undefined method `postcode_changed?' for #<Use...

I have a Rails app that is storing some user information in a cookie, and that information isn't being stored as soon as I would like. A client that is performing five requests in a row from a single page has an empty cookie until the page has completely loaded, and then for the future, the cookie is populated. It is behaving as if the...
I've got a form with nested objects as described here: http://ryandaigle.com/articles/2009/2/1/what-s-new-in-edge-rails-nested-attributes It's working fine, but I need to sort the nested objects in the form by their "name" attribute so they are listed in alphabetical order. Any ideas? ...
I am writing a plugin that provides drafting for models. A delete action is a draftable action and I do not always want to delete the origin until that deletion is published. So I wrote my own destroy method to help out with this. Everything works exactly as I want things to except, custom callbacks for :before_destroy and :after_dest...

I have a simple find statement as such: m = MyModel.find(1, :include => :my_children) With m.mychildren being an Array; is there anyway to find a particular record from within the array without having to iterate over the entire thing. If I do mychildren.find(1), a new DB query is issues, which doesn't make sense, since they are all lo...
