Question

I am using a form_for method in a form that gets rendered by the edit action. I want to pass a parameter to the update action. I am using hidden_field to do that with parameters already, but these are all being saved to the model upon update. What if I want to pass a parameter that is not an attribute of the model. How would I do that?

Answer 1

Don’t link the hidden field to the form variable:

<%= hidden_field_tag :name, val %>
