Records loaded through joins with piggy-back attributes will be marked as read only as they cannot be saved and return true to this query.

Making ActiveRecord models readonly

autonomous ยท Oct 2, 20092 thanks

To force an ActiveRecord model to be read only you can do something along these lines:

class DelicateInfo < ActiveRecord::Base

def readonly?

true end

end

When you try to save the model it will raise an ActiveRecord::ReadOnlyRecord exception:

info = DelicateInfo.first info.save # => ActiveRecord::ReadOnlyRecord

Note, however, that destroy and delete will still work on the model unless you intercept those calls
