Have you worked right through the tutorial I suggested, including the
exercises?

Hi!

Take a look into strong parameters
http://api.rubyonrails.org/classes/ActionController/Parameters.html.

Since Rails 4, you couldn’t just forward a complete params hash to your
model. You could but you have to deactivate Strong Parameters before.
Anyways, I highly recommend you to follow this practices since your
approach opens a really big vulnerability.

For example:

You have an attribute “role” in your model. The user just have to add
the
attribute “role” to the parameters and is able to modify this protected
attribute.

Happy coding :slight_smile:
