When Rails loads, does it load all the gems that are installed on the system? I've got 47 gems installed on the server, including all the various Rails gems which have multiple versions. However, both Rails, and all the gems used by the application, are frozen into the application. Are all those gems getting loaded, and would that cause...
There might be a better way to do this, but I'm trying to make an if statement in rails, based on the current action, in a controller (this will be used in a view).

Hi, I have a rails app that I'm moving to another server and I figure I should use db:schema:load to create the mysql database because it's recommended. My problem is that I'm using capistrano to deploy and it seems to be defaulting to rake db:migrate instead. Is there a way to change this or is capistrano using db:migrate for a good re...

I need to inspect the bits of an uploaded file before it's ever saved off to the file system. PHP's documentation has a nice page that tells me exactly what properties are available for me to use (http://us3.php.net/manual/en/features.file-upload.post-method.php), but I can't find something similar for Ruby and/or Rails. I've also tried...

Alright. While there are a few blog posts here and there purporting to make this process easy, this is absolutely driving me crazy. Here's what I've done: I've installed FreeTDS (with and without +mssql) but encounter problems when I use it to connect to my remote DB instance. When I attempt tsql -H [remote-db-ip] -p 1433 -U [valid-...

As far as I know, .rhtml is deprecated in Rails 2. In some guides there is only .erb, but both RubyMine and NetBeans IDE generate .html.erb and I've also seen it many people using. I've tested both and they seem to work fine without any errors or warnings, but which one is correct? .erb or .html.erb ...

Rails has a nice idiom that makes it easy for you to have a single action method return properly formated data (json, xml, just the data) based on the format specified by the client (or else deduced from the request. It looks something like this ... respond_to do |format| format.html #edit.html.erb format.json {render :text=> <your...
I ran in to an interesting problem while using the 'tap' method on objects of type 'String'. "abc".tap { |o| o = "xyz" } # this line returns "abc" instead of "xyz" The 'tap' method works on objects of other types.

The ability to have flash messages (notice, error, warning, etc) with embedded links is nice from a user interaction standpoint. However, embedding an anchor tag inside a flash message from the controller is dirty.
