Hi, I'm currently writing a Rails 3 app that uses the google maps API (v3) extensively. Currently, the infowindow for each marker contains a link that takes the user to the page for that particular marker - ie. /places/1. A sample of my code is below: jQuery.getJSON("/places", function(json) { if (json.length > 0) { for (...

At the moment any information that's entered into the database is eith...

When I save an apartment record in rails, for some reason it is updating the updated_on field and the created_on field. I can't figure out how/why the created_on field is being updated.

Hi, I am building a social networking site in rails and I want to have a very simple messaging system. More or less just: inbox and set messages. Lastly, I'd ideally like for it to function like facebook; in the users profile you click "send message to username" and it takes you to a compose screen. The only rails messaging system I'v...
For some reason, one of my models in rails is returning nil when I call .new. This is only a problem in the controller. When I try on the console, it returns an object with nil attributes as I would expect. I suspect the problem is in my controller, but I have no idea. This also happens when I call .all. Again, I can execute these comm...
Say you have a Post model that has a :title, :author, :content, etc. It also has a :thread_id attribute, and it belongs_to :thread. The thread model doesn't have any custom fields. The only ones you'll be needing are those created by default such as :id, :created_at, and :updated_at. Threads have_many :posts. How do you create a form f...

I read a few tutorials on getting memcached set up with Rails (2.3.5), and I'm a bit lost. Here's what I need to cache: I have user-specific settings that are stored in the db. The settings are queried in the ApplicationController meaning that a query is running per-request. I understand that Rails has built-in support for SQL cachei...
