I'm trying to extract some common code into a gem. I'm thinking that acts_as_somethingis a good strategy for simple re-use. Is there a good tutorial that discusses this for rails3 gems? I've found several that discuss rails2 (such as http://guides.rubyonrails.org/plugins.html) but that is specific to rails2 here are some of the tuto...

Given: <%=form_for [:project, @note], :remote => true do |f| %> I'd like to create a jquery bind that automatically saves every few seconds. I'm not worried about the timing part yet, just how to use jquery to submit the form automatically (ie, not submit button click by the user.) I tried this, but it isn't working. Suggestions? $(...
I'm having trouble with the Authlogic-gem. Before I write my own auth-scheme I wanted to ask if anyone had the same problem: When logging in it successfully executes the user_session.save and redirects, but the "current_user" is not set. It works perfectly locally, but it won't when using Passenger. I updated Passenger to 3.0 but no lu...
Hi. Here's what I'm trying to do. when the user clicks new note.. I want the user to be taken to a page when they can start typing a note, and save it to the server all with AJAX.. Problem is, every time the page saves, it's making a new note. This leads me to believe that when Rails gets the DEF NEW controller, some how I need rails ...
I have installed RVM and as noted in the install http://rvm.beginrescueend.com/rvm/install/ I was able to get "rvm is a function." A lot of what I've read recommends not to use sudo gem install bundler, but it did not work without sudo (the error said I was not able to write to var/lib/gems/1.8 with gem install bundler) Even after "Su...
I added a table that I thought I was going to need, but now no longer plan on using it. How should I remove that table? I've already ran migrations, so the table is in my database. I figure rails generate migration should be able to handle this, but I haven't figured out how yet. I've tried rails generate migration drop_tablename, but ...

At the RMagick repo on Github, a message was uploaded yesterday saying the main author cannot continue to maintain the project, and is looking for new people to take over. (I would certainly crash it were I to ever attempt such a job!). You can see their readme here: http://github.com/rmagick/rmagick. In your opinion, where should a Rai...

Hello. I'm getting ready to build search capabilities into my app. I want the search to have the ability to span multiple models. I'm thinking about adding a search controller which would then decide which models to search based on settings etc... What do you think? Does a search controller sound right or is there something open-source...

I have a macbook that has Leopard (OS X 10.5) but don't have Snow Leopard. It ran Rails 2.3.8 fine, but now when it comes to Rails 3.x, with Ruby 1.9.2 (or 1.8.7), gem install cannot build mysql, mysql2, or sqlite3-ruby, so essentially, this macbook can't use Rails 3.x at all? Is there a way? thanks. (it seems that the latest Xcode ...

Is there a reason why all sqlite3, mysql, postgres driver compiles on Mac OS X Leopard when it is Rails 2.3.8, but can't compile when it is Rails 3.x? Theoretically, isn't it just some compile flags to make them work? (They all compile on Snow Leopard with the latest Xcode, but can't compile with Leopard with a slightly older Xcode... ...
