I have a model that I'm trying to retrieve an array of data from, and I don't need the data to be instantiated into Ruby objects. In fact, that just introduces an extra step into my code to step through the objects and generate a new array with just the data I need. Example: class Book #has attribute in database title end I would ...
I am trying to build a Rails app with multiple models in a single form, and multiple forms on a single page. To make that work (according to my limited knowledge), I have to drop out of the scaffold code and the "form_for :model" helper and use "form_tag" instead. However when I do that, I lose the ability to automatically catch and repo...
When my project is growing up, I need to write some methods, but application_controller's private methods and helpers aren't provide enough space to store all extensions. So I have looked at custom classes and methods, which are stored in the /lib folder. But i still have some questions, which i can't solve: -When should I use "class ...
I'm working on a Rails app and using the restful-authentication plugin. The app will include user images. Only users who log in will be able to browse, but I wondered if I can also restrict direct URL access to the images to only allow logged-in users. In other words, even if you know that an image is at thesite.com/user1/foo.jpg, you c...

Hi, it's about Ruby On Rails. I want to use Googleauth and need to add a line starting with "config.gem" in the Rails:Initializers block in the environment.rb. Sadly, Passenger tells me that this would be an unkown command. config.gem "googlebase", :lib => 'google/base', :version => '0.2' What do I have to change to get, possibly be...
There are currently two problems with storing ActiveRecord objects in memcached. The Undefined Class/Module problem (Google search). From what I've read up, this is still a bug that nobody has a real good solution for. The cache_fu plugin has probably the best solution for this, wrapping its retrieve call in a block that tries to catc...

I have a RoR project on my Windows 7 PC. I want to create some Ruby code that I can execute from the cmd.exe command line that manipulates the development database (via database.yml) of the project. (I don't want to have to run my utility code via a web page.) What is the best way to go about pulling this off? (I'm a newbie.) I can'...
This code runs on my local RoR/Windows 7 (64-bit): sql = ActiveRecord::Base.connection() last_pk = sql.insert("insert into manual (name) values ('hello new value')") puts 'last_pk=', last_pk but always displays "0." For various reasons I can't use ActiveRecord in this situation. (Note: The above code runs fine on my shared host. A...

Something I've always wondered about rails is the ability to pass extra data to find_or_create methods in rails. For example, I can't do the following User.find_or_create_by_name('ceilingfish', :email => '[email protected]', :legs => true, :face => false) I could do u = User.find_or_create_by_name('ceilingfish') u.update_attributes(...

I have a set of columns that applies to more than 1 model. For the sake of discussion, it could be: User has many Addresses Company has an Address These are separate models, but the Address columns will be identical between the 2. What's the best way to accomplish this in Rails? ...

I've just upgraded from MRI-1.8.7 to MRI-1.9.1 and heard about this lighthouse ticket which indicates that Ruby 1.9.1 and Rails 2.3.x won't play nicely together when a user enters any kind of non-ASCII standard character (i.e. å é Ã Ø å ल) unless rails is patched. My problem is that I CAN'T reproduce the bug. I've tried everything. I'...
