Answer 1

You can use accepts_nested_attributes_for in your User model (documentation)

It should look like:

class User < ActiveRecord::Base
  belongs_to :organization
  accepts_nested_attributes_for :organization
end

class Organization < ActiveRecord::Base
  has_many :users
end

In views you could use Rails helper or create field by hand:

<input type="text" name="user[organization_attributes][name]">

<% user = User.new(organization => Organization.new) %>
<%= form_for user do |form| %>
  <%= form.fields_for user.organization do |organization_form| %>
    <%= organization_form.text_field :name %>
  <% end %>
<% end %>

EDIT: Your devise view should look like:

<h2>Sign up</h2>
<% resource.organization ||= Organization.new %>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>
  <div><%= f.label :email %><br />
  <%= f.email_field :email %></div>

  <%= f.fields_for resource.organization do |organization_form| %> 
    <div><%= organization_form.label :name %><br />
    <%= organization_form.text_field :name %></div>
  <% end %>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>
  <div><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></div>
  <div><%= f.submit "Sign up" %></div>
<% end %>
<%= render :partial => "devise/shared/links" %>
