deprecated_mass_assignment_security.rb:17:in `attr_accessible': `attr_accessible` is extracted out of Rails into a gem. Please use new recommended protection model for params(strong_parameters) or add `protected_attributes` to your Gemfile to use old one. (RuntimeError)
I tried what the message says, adding gem 'strong_parameters'
to my Gemfile
.
But when I do rails s
I get the error above.
I tried:
config.active_record.whitelist_attributes = true
in confgi/application.rb
, also with false
, but actually I don't understand that option.
In your Gemfile you will notice that gem 'protected_attributes'
has been hashed out.
Remove the hash.
Run bundle install
.
But since protected_attributes has been deprecated and may disappear in the future use strong_parameters as mentioned in the above post.
For more info on strong_parameters refer this link.
