In trying to solve the "ajax back button" problem I have found the Really Simply History library. Has anyone tried to integrate it with Rails? It's plain old javascript so it seems like it should integrate just fine, but I know next to nothing about JS itself, so I'm not too confident in trying to do the integration without a tutorial...
I'm a PHP developer who knows a little bit of Ruby. I want to learn Ruby on Rails, but most of the resources I've come across treat RoR functionality as "magic" -- i.e., it has a certain internal consistency, but don't bother asking how it works in terms of Ruby, MySQL, etc. Anyway, I want a deep understanding of how RoR works, the desi...
I'm running a mySQL database locally for development, but deploying to Heroku which uses postgres. Heroku handles almost everything, except that my case insensitive Like statements become case sensitive. I know I could use iLike statements, but my local mySQL database can't handle that. What is the best way to write a case insensitive q...

Should i stay out of rails if a client has a cheap hosting service with a provider that do not support mod_rails? Will rails + fast.cgi provide a good experience for a user or should I choose, in this scenario, php + my-favorite-framework as platform ? Regards, Victor ...
This is similar to a previous question on Rails Books, but I'm looking for a little more detail on something that was brought up in that thread. I'm starting a project using Rails 2.0 next week, and I'd like a book to read to get going. Dead-tree format is a must, this is for the bus. Agile Web Development with Rails seems to be the ...
Hopefully I haven't misunderstood the meaning of "duck typing", but from what I've read, it means that I should write code based on how an object responds to methods rather than what type/class it is. Here's the code: def convert_hash(hash) if hash.keys.all? { |k| k.is_a?(Integer) } return hash elsif hash.keys.all? { |k| k.is_a...
I'm attempting to put together some basic report screens. I've got some fairly complicated SQL queries that I'm feeding into ActiveRecord's find_by_sql method. The problem I am having here is that I am losing the order of the columns as given in the original query. I'm assuming that this is because the Hash class does not preserve ent...

I am struggling with the route setup for a Rails application. I have installed restful_authentication and mostly followed the instructions. I have set up the routes this way: map.login '/login', :controller => 'sessions', :action => 'new' map.logout '/logout', :controller => 'sessions', :action => 'destroy' map.resource :session If yo...
I have a namespaced controller for some admin functionality. My create form does not work -- it ends up routing the request to the index action instead of the create action. Why isn't the POST getting routed to the create action as it should (being RESTful)? routes.rb: map.namespace :admin do |admin| admin.resources :events ...
I have a drop down like this on my page: <p> <%= f.label :episode_id %><br /> <%= f.collection_select(:episode_id, @episodes, :id, :show) %> </p> An episode has an id and belongs_to to a show which has a name. In the dropdown, I'd like to display the show name. :show.name doesn't work to display the name. How do I do this...

How can I go about making my routes recognise an optional prefix parameter as follows: /*lang/controller/id In that the lang part is optional, and has a default value if it's not specified in the URL: /en/posts/1 => lang = en /fr/posts/1 => lang = fr /posts/1 => lang = en EDIT Ideally, I'm looking to do this across many c...
