Adding content and widgets to a form view

The previous recipe showed how to pick a specific view for an action. Now we'll demonstrate how to make the form we defined previously more useful.

How to do it...

1. Define the form view basic structure:

   <record id="form_all_customers" model="ir.ui.view">
     <field name="name">All customers</field>
     <field name="model">res.partner</field>
     <field name="arch" type="xml">

         <!--form content goes here -->
       </form>
     </field>

         <header>
           <button type="object" 
                   name="open_commercial_entity"
                   string="Open commercial partner"       
                   class="oe_highlight" />
         </header>

3. Add fields to the form, using group tags to visually organize them:

         <group string="Content" name="my_content">
           &lt...
