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:

cd ~

# download the Node source, compile and install it
git clone https://github.com/joyent/node.git
cd node
./configure
make
sudo make install

# install the Node package manager for later use
