title: stefanfoulis/django-phonenumber-field display format of phone number in template
body: <p>I'm trying to figure out how to display a phone number using stefanfoulis/django-phonenumber-field.  I have stefanfoulis/django-phonenumber-field[phonenumberslite] installed.  In my settings file I have:</p>
  
  <pre><code>PHONENUMBER_DB_FORMAT = "NATIONAL"
  PHONENUMBER_DEFAULT_REGION = "US"
  </code></pre>
  
  <p>In my model I have:</p>
  
  <pre><code>phone_number = PhoneNumberField(blank=True)
  </code></pre>
  
  <p>In my form I have:</p>
  
  <pre><code>phone_number = PhoneNumberField(max_length=25,required=False)
  </code></pre>
  
  <p>And in my template I have:</p>
  
  <pre><code>{{ myform.phone_number }}
  </code></pre>
  
  <p>I am able to enter a phone number in a variety of formats (831-555-5555, 831-555-5555, 831.555.5555) and it stores properly in the database as +18315555555.</p>
  
  <p>But when I use the form field in a template it always displays as +18315555555. I would like it to display as either 831-555-5555 or (831) 555-5555. How do I make the phone number display in one of these formats in my template?  Is there a tag modifier?  </p>
  
  <p>UPDATE: As it turns out I was setting the initial value of the form field in the form <strong>init</strong> method and I needed to set it to as_national.  It is now being set to (831) 555-5555.</p>
