Currently I'm getting something like: Started GET "/" for 127.0.0.1 at 2011-08-27 13:13:10 +0200 but I need to get: Started GET "http://localhost:3000/" for 127.0.0.1 at 2011-08-27 13:13:10 +0200 because this is an app where the domains are important. 回答1: As of Rails 3.2.12, instead of monkey-patching before_dispatch or call_app, there is now a method that receives the request and returns the Started GET "/session/new" for 127.0.0.1 at 2012-09-26 14:51:42

As of now, I am able to create everything nicely in Active Admin and have it displaying through the show action on the app interface. Here is the problem I have. I want to display the form title (which is working), along with the form questions (which is working), along with input fields to submit new form answers on the fly (which is the part that is not working). I feel like I have exhausted everything when it comes to nested forms. I

I've set up some scopes (with many more to come): # in the model: scope : budget_min , lambda {| min | where ( "budget > ?" , min )} scope : budget_max , lambda {| max | where ( "budget < ?" , max )} ...but what's the best way to use some, none, or all of these scopes based on the present params[] ?
