I've managed to deploy my app to production using Capistrano, but I don't understand how to deal with my database. I'm using subversion and passenger. When I run cap deploy, the new deployment starts everything fresh. It wipes out the data that was added to the database. Obviously, there must be a solution, but I'm very surprised not...
It seems all the examples I come across specifiy an UpdateTargetId to render out the HTML content of the Ajax response. This is quite a bit different than how it's done in the Rails world, where the response content contains JavaScript code which manipulates the page. The Rails convention seems more powerful. What's the recommended usag...

Now in a survey, there can be up to 200 questions and so one survey can generate up to 200 answer-models in a page. The question is: How can I save the array of answers I have in a single db-action and not ite...
I want a "friend" relationship, as in "social site friends", which means: if I'm friending you you invariably friend me. If I remove you from friends, you do that, too. (well, you get the idea). Currently this is done with duplicate relations and an observer to add/remove the second (more correctly, "other") relation when the first gets...
Hi, I am trying to design a very flexible model like google docs survey. It's a bulletin board post model. And admin(or site builder) can add boards freely. But instead of fixed columns, admin can define additional columns. So the post model can be used for many other purposes. I have currently 2 models - board and post. A board has m...
I have an application where I'm creating a new object via a "new" action. Rails is using the correct controller action, and also rendering out the new form correctly. However, the path for the form is coming up with an Id for an edit which is breaking things. The form tag is just: <% form_for @issue do |f| etc Any ideas as to why ...
Hello guys, I hope you can help me. I have a User entity that has a Current Location field (city and country). To old this info I created an entity called Location which has_many Users.

I'm starting a Rails app for a customer and am considering either creating a mind map or jumping straight to a Cucumber specification. How do you plan your Rails app?

My problem: I'm writing a flex frontend to a rails app, and I'm having problems in managing NULL database values.. so to avoid problems I just don't allow NULL. Now, for foreign keys, would 0 be fine? No chance that a record be assigned ID 0, right? Maybe I could somehow tell rails to skip foreign key updates if input is 0.. ...

We're interested in logging and computing the number of times an item comes up in search or on a list page. With 50k unique visitors a day, we're expecting we could produce 3-4 million 'impressions' per day, which isn't a terribly high amount, but one we'd like to architect well. We don't need to read this data in real time, but woul...
