Retrieve values of an entity by the Django's template with db.ListProperty(db.Key)

Thanks to this post I changed my class to:

class Foo(db.Model):
    name = db.StringProperty(multiline=True)   
    bars = db.ListProperty(db.Key)

class Bar(db.Model):
    name = db.StringProperty(multiline=True)

Here a piece of my Django Template

   <div >
     <h3>{{ current_foo.name }}</h3>
      {% for bar in current_foo.bars %}
         <a href="/dialog_bar.html?id={{ bar.id }}"  >{{ bar.name }}</a>
      {% endfor %}
    </div>

I don't manage to get the bars's name and the bars's id, How Can I do that?
What am I missing?

The best bet is to define a simple method or property on your Foo model that queries the database for the relevant Bars.

class Foo(db.Model):
    ...
    def get_bars(self):
        return db.get(self.bars)

Then you can call this in the template:

{% for bar in current_foo.get_bars %}
