Safe Mass Assignment
Allows (careful) mass assignment of protected attributes, separate from values provided via users of your application.
When creating models via ActiveRecord, it is good practice to use attr_protected or (even better) attr_accessible to prevent malicious (or clueless) users from assigning values to attributes that you did not intend to be assignable via the web interface. Unfortunately, this results in clumsy situations where you need your program to be able to assign to those attributes:
user.attributes = params[:user] user.admin = true user.save
This plugin adds a second parameter to create, update_attributes, and related, which will always mass-assign, regardless of attr_protected or attr_accessible:
user.update_attributes(params[:user], :admin => true)
Naturally, clueless programmers will still be able to make a muck of this, but as long as you ensure that the second parameter is never using values provided by the user, you'll be just as secure as if you were using the first (more verbose) version.
Account.create(params[:account], :comped => true) Account.create!(params[:account], :comped => true) account.update_attributes(params[:account], :comped => true) account.update_attributes!(params[:account], :comped => true) account.users.create(params[:user], :admin => true) account.users.create!(params[:user], :admin => true)
