The Problem

If you have installed the standalone Command Line Tools for XCode on your Mac (i.e. without having XCode.app installed), some of these tools can get a bit confused due to a couple of oversights on Apple's part in finalising the setup.

Note: all commands below will need to be run from an Administrator account, or by an account with appropriate permission in /etc/sudoers.

The Solution

1. Failing to Find Frameworks

Sometime when compiling against the preinstalled Frameworks (e.g. Ruby or Python), various tools will inexplicable fail to find header files that are quite clearly there. This is caused by the fact that no XCode has been selected for the command-line tools. Wait, I hear you cry, I don't have XCode installed! Indeed, but you nonetheless need to select one, and point it somewhere where the command line tools exist, like so

VirtualBox仮想マシンのネットワークはデフォルトでNATとなっている。 VirtualBox の場合、NAT ネットワークアダプタには 10.0.2.0/24 の IP アドレスが割り当てられ、ゲスト OS から見える ホスト OS の IP アドレスには 10.0.2.2 が設定される仕様。

したがってホストOS上に建てたサーバーにゲストOSからアクセスしたい場合は、http://10.0.2.2とアクセスすれば普通に見ることができる。

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:
