OK, so I get that ActiveRecord determines model attributes through reflection of the table schema. Handy for many cases, but not mine. I need to override that and provide my own mapping of attribute names to column names to use the mapped names throughout the application code. I''ve been poking around looking for where in AR''s hierarchy I can can inject this mapping, but

Hi Gurus- I want to return the variety from the species table based on the active record link to inventory table class Species < ActiveRecord::Base has_many :inventories end class Inventory < ActiveRecord::Base belongs_to :species (this is the singular and the plural, so that''s OK) end My inventory_controller looks like: def show @inventory =

So I''ve googled my brains out, and I see a lot of talk about TextHelper for views, but next to no discussion about cleaning text _before_ it is saved. I figured this had to be asked 4 zillion times, but I''m not finding anything concrete/obvious. Using h is fine as a safety catch, but that alone is not acceptable to me as the means of diffusing the impact of HTML or JS

I have the need to take existing PDFs and populate them with data entered via HTML forms. Data saved to database, entered in to PDF file, PDF file with data archived, and then distributed va email and/ or download. The languuage I previous did all my web work in, Lasso, had this stuff built in, but it appears not to be so with Ruby or Rails. The latest info I can find on this is a year

What I''d like to do: Capture the IP addresses of the folks visiting a web site in the Sessions table. What needs to be in place (code, model, controller, etc.), where does it need to go (application controller?), how best to set up the Sessions table? Appreciate a noob-friendly outline of what needs to be done. Thanks. --~--~---------~--~----~------------~-------~--~----~ You

Is there a method to return a hash of the route configuration based on a path? For example: magic_method(''/my_controller/my_action/my_id'') => {:controller => ''my_controller'', :action => ''my_action'', :id => ''my_id''} Thanks!

I''m writing a wizard-like module in my application where, in a series of steps, the user builds upon an ActiveRecord object, and in the end, saves the AR object into the database. The ActiveRecord object is fairly complex, with a has_many association that could potentially get large, so I don''t want to store it directly in the session. In fact, having done so already caused a

Hello everyone, I''m almost cracking my head trying to do this birthdate validation. It turns out that I can only accept users with at least 18 years old and I''m trying to validate it writing this code on my user.rb fil at app/ models class User < ActiveRecord::Base validates_presence_of :full_name validates_presence_of :street_address validates_presence_of :city

Hi all Sometimes I check in a controller if the method is GET or POST. But afaik there are other methods - do I have to care about them? Is the following enough? if request.get? ... elsif request.post? ... end Or do I have to add also an else block? if request.get? ... elsif request.post? ... else raise "Boah!" end Thanks for infos Josh -- Posted via http://www.ruby-forum.com/.

on previous apps i hadn''t really worried much about adding foreign key indexes on my tables just because they''ve been fairly small and i didn''t really think i needed them. well, i''m working on something now that has the potential to have a lot more data, and a lot more foreign keys. so i have 3 tables... users, projects, and tasks.. should i be using add_index

So, I''ve been pounding the web for info on UTF8 in Ruby and Rails the past couple days to concoct some validations that allow UTF8 characters. I have discovered that with the patches applied in Rails 1.2, I can get a little further by doing the following declaring $KCODE = ''UTF8'' in environment.rb and by adding /u to regex expressions. The only thing not working

I need to serialize a composite AR model and save it to a database field. Reading up on Ruby''s Marshaling, it seems there could be problems with the version numbering thing of the default dump/load methods. As I understand it, Ruby internally marks the serialized data with the current Ruby language version, and when loading that data, if the major version is changed, the loading

I''ve created a module to include in a Controller. Basically it works, but I am expecting methods in the module to have access to instance variables from the controller, and that appears to not be the case. Yet, a simple Ruby example says it should be. I''m not sure what''s different. Simple Example: module ShapeStuff def set_type @type =

What''s the syntax to acquire the updated_at value of a session stored in a db? session.updated_at doesn''t work. can''t find any docs on this. -- gw --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

One of the areas where I think Rails goes too far is in many of the helpers that (AFAICT) do nothing more than change the syntax used to write simple HTML tags. link_to and many of the form tags come to mind. For me, these helpers aren''t that helpful. I find the HTML much clearer to write and read, I don''t see any added value in the overhead costs of using code to

I am storing a shape object in a session, and somewhere I picked up that to make sure I can restore the full glory of Shape, I needed this line in ApplicationController model :Shape So, of course, I also have a file /app/models/shape.rb All was working well, but then I decided I''d rather name the model MyShape. So, I - edited the filename to "my_shape.rb" - edited
