Django Template Data

I have the following models:

class Contactnumber(TimeStampedModel):
    phone_number = models.CharField(max_length=100, unique=True)
    contact = models.ForeignKey(‘contacts.Contact')

class Contact(TimeStampedModel):
        contact = models.CharField(max_length=100, db_index=True,
                               verbose_name='Contact Name')
        practice = models.ManyToManyField(‘practice.Practice’,
                                      related_name=“contacts",)



class Practice(TimeStampedModel):
       practice = models.CharField(max_length=150, db_index=True,
                                verbose_name='Practice Name')

I have a template including data tables in which I want to show the following: Practice, Contact, Contact Phone

The following gives me the contact for the practice: 

{% for contact in practice.contacts.all %}
    {{ contact }}
    {% endfor %}

My question is how do include the contact phone number as I seem a bit lost. Any help would be appreciated. Apologies if this is a simple question!

ATM your contacts can have multiple phone numbers, so one way would be to do it like this: 

{% for contact in practice.contacts.all %}
    {% for number in contact.contactnumber_set.all %}
        {{ number.phone_number }}
    {% endfor %}
{% endfor %}

The logic behing this is that when you haven't set a related_name to a relation field (one2one, FK, M2M), then you can access the related model by the model's name and adding "_set" to the end. So you iterate over all contacts and over all numbers that a contact has and the output will be all the numbers for those guys. Feel free to format it any way you like (adding commas, <br>'s and so on).
