Question

I would like to add simple terms validator to my form:

Model

attr_accessor :terms
validates :terms, :acceptance => {:accept => true}, :allow_nil => false

View(simple_form)

= simple_form_for @student, html: { multipart: true } do |f|
   ...
= f.input :terms, as: :select
= f.button :submit

But I get:

Can't mass-assign protected attributes: terms

What I am doing wrong?

Answer 1

You can try with:

field :terms, :type => Boolean, :default => false
attr_accessible :terms
validates :terms, :acceptance => {:accept => true}

On your view:

<%= f.input :agree, :as => :boolean, label: false %>
