Question

New to python, and trying to use __unicode_ to render a string representation. The code is part of Django model. How can I write __unicode__ of MyType so that in templates it output its representation as 123 - 123 South ....

class UsAddress(models.Model):
    #other fields
    zip = us_models.USPostalCodeField()
    country = models.CharField(max_length=2)
    phone = us_models.PhoneNumberField()

    def __unicode__(self):
        return  self.zip + self.country + self.phone


class MyType(models.Model):
    code = models.IntegerField()
    address = UsAddress

    def __unicode__(self):
        return str(self.code) + " - " + unicode(self.address) #self.address.__unicode__()

Output:

 <MyType: 219 - <class 'web.models.UsAddress'>>

EDIT

At least in my case, the problem was I didn’t model the relationship. So I added it to UsAddress.

mt = models.ForeignKey(MyType)

Answer 1

Try this:

class MyType(models.Model):
    code = models.IntegerField()
    address = UsAddress

    def __unicode__(self):
        return u'%s - %s' % (self.code, self.address)

Here is the unicode method.

Then, you can just use it in your template like this:

<p>My object: {{ mytype_obj }}</p>

The output will be:

My object: 123 – 123 South ….
