Database is not updating after the Active Record Migration

Rails
1

Hello.

I created a simple database to test adding a column in an active record
migration. Using phpMyAdmin and ROR, this is the code I used for the
migration:

class AddColumns < ActiveRecord::Migration
def self.up
add_column :users, :need_it, :boolean
end

def self.down
remove_column :users, :need_it
end
end

the migration went successfully, as I can see the newly created column
in
phpMyAdmin.
The column is, trying to be, mapped to a checkbox, located in the
_form.html.erb file:

<%= form_for(@user) do |f| %>
…
…
…

<%= f. label :need_it &>
<%= f.check_box :need_it %>

…
<% end %>

But when I enter a new user and select the checkbox, or edit a current
user’s checkbox field, the new value doesn’t show in the database
(MySQL).

What am I missing?

Thanks.

You probably didn’t add :need_it to the strong parameters
(params.require(:users).permit(:need_it)) or if you’re using Rails 3.x,
you
didn’t add it to attr_accessible.

The first technique when looking for any bug is to determine the area
of code that is failing. Look in log/development.log and you will see
the parameters passed when you submit the form. If the checkbox value
is not there then it is the view that is at fault, if the checkbox is
there then it is the controller code that is in error somewhere.
