Question

class Company < ActiveRecord::Base
  has_many :users
end

The user hits on Company->Users href link and assuming it shows 3 users for a certain company.

I would want to set user.age (an integer) for all the users and press save. How do I do this in my controller / view code?

We usually have an Edit link against each User to modify its details, but I would like to set age information for all users.

Answer 1

Use a form_tag to submit to an arbitrary controller action set up specifically for editing multiple users (not one of your user scaffold methods). Then, add one fields_for tag per user inside of the form you created, each with a field for the age attribute. When submitted, you can simply iterate over the user params in the controller to manipulate your users.
