tl;dr

• If .strip isn't working, try .gsub(/\A[[:space:]]+|[[:space:]]+\z/, '')

Notes showing different ways to us AJAX forms in Rails. We will use a Todo list as an example domain for the examples.

Lowest level of abstraction

views/lists/index.erb.html This will create the list input form (Note: This should also work in Sinatra)

<% form_for List.new do |f| %>

From: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html

To create a new person you typically set up a new instance of Person in the PeopleController#new action, @person, and in the view template pass that object to form_for:

<%= form_for @person do |f| %>
  <%= f.label :first_name %>:
  <%= f.text_field :first_name %><br />

  <%= f.label :last_name %>:
  <%= f.text_field :last_name %><br />
