similar to: before_save gotcha

First off, congrats to everyone for getting Rails 2 released. A lot of work went into the release, and it''s good to see us reach this milestone. And now that the release dust has settled, I think it might be useful for us to have a retrospective and evaluate how the release went. I think the Ruby on Rails project has improved a lot this year, and this is another opportunity

Which is more appropriate? @session[] or session[]? Both seem to work. Is there a difference between which should be used in the controller vs. the view?

What is the most elegant way to save new one-many associations? order = Order.new(:name => "My Order") order.line_items << LineItem.new(:product_id => 1, :quantity => 2) order.line_items << LineItem.new(:product_id => 2, :quantity => 5) order.save The above - which is by far the most elegant way of putting it - doesn''t work for me - the line_items

The revised patch submitted on #4748 broke the build, I''m looking to sort out why. Also note that this auto-test email didn''t make it to rails-core because it was too big (every test failed, so the resulting email was huge). I''ll patch my auto-testing script to truncate the email to no larger than a few kb. Michael Schoen wrote: > "marcel" made

I tried the current Typo trunk with Edge Rails (1.1.0 RC1) and ran into the following problems: 1) /public/../config/environment.rb:107: undefined method `enable_upload_progress'' for ActionController::Base:Class (NoMethodError). I commented this line out and installed the Upload Progress plugin and this problem _appears_ to have gone away. 2) The second problem I

I am building an invoicing system but cannot use the auto_increment field to determine the invoice number (because they are running 3 different companies off the one system. I need to find the last invoice number from any given company and then add 1 to it to get the next invoice number. BUT, there is a unique case on the very first invoice produced because there is no earlier invoice

I didn''t get the memo on this :P members_controller.rb:12: warning: Object#id will be deprecated; use Object#object_id Line 12 is: @member = Member.find(@current_member.id) How _should_ I be writing that line? Thanks, Joe -- Posted via http://www.ruby-forum.com/.

I started with Ruby on Rails in the 0.13.x period, so I''m sure I missed out on a lot of history. There''s probably some good explanation for something I''ve been wondering about, but I haven''t seen it written down anywhere. Maybe someone can clue me in. I''ve always felt that one of the uglier APIs was the ActiveRecord::find() method. I call

I am having a problem finding the best way to make a "before_save :encrypt_password" conditional. I have to at times update user model attributes but each time I do this the password is reencrypted because of the above. I need to differentiate between when the user is first logging in and the password does need to be encrypted, and when they are already logged in and the

I just saw Marcel''s change to assert_difference that changes the method API to take a string param that is evaled in a lambda. http://dev.rubyonrails.org/changeset/6693 I much preferred the old API, since it''s simple enough to pass a lambda. Passing a string means the lambda is in the wrong scope and doesn''t have access to objects in the test case scope. For an

Hi all, I''ve been using RJS more and more for my app and I have sorta run into a possible issue. My app has different user roles that require different layouts. So far, this has worked fine, but now that I''m using rjs more and more I''m finding that the two don''t really work together since I have to rails not to use a layout upon controller method

Hi all, I was wondering about the class used when rails receives file uploads. Sometimes it appears to be a File, and other times it is a StringIO. Also it has methods such as original_filename that don''t appear to belong to either of these classes. I ask because I''m trying to work out how to test my fil upload related models and controllers. Is there some standardised way of

I''m trying to work with a many-to-many relationship, but the join table needs to have a is_primary field. What is the best way to work with this (adding / changing primary / deleting)? I understand that the :through option in Edge Rails can handle this better, but I was just wondering if there was a good way to handle this with Rails 1.0. Thanks, Kyle

This is probably more of a Ruby question than a Rails question. I''ve always wondered exactly how controller instance variables are being made accessible to the ERb code in the views. In the Agile Rails book on pages 38, there''s a sidebar at the top that hints at what''s going on: "Rails does some Ruby magic so that the instance variables of the controller

Hi, I''d like to upcase a variable before it is saved, but I''m not sure how to access the incoming param or where this work should be performed: In my update method, I have: @device = Device.find(params[:id]) params[:device[macaddress]].upcase <-- problem code if @device.update_attributes(params[:device]) ....usual stuff here ''macaddress'' is the

I''ve got the following setup: category (hm) <-> (bt) activity An activity has an amount, date, location, note, and category. I''m sorting my activities table by category_id (foreign key in activity), but how do I sort it by category_name instead? Basically I just need category_name in the result set. Here''s what I have now: @all = Activity.find(:all, :order
