Trying to format returned _set

I am trying to populate my form with a list of plans.

Here is my unicode for the Plans model

def __unicode__(self):
    label = "ID: %s, Member(s): %s, Plan Type: %s" % (self.id, self.get_owners(), self.plan_type)
    return unicode(label)

Now I call get_owners which is shown below:

de开发者_开发百科f get_owners(self):
    owners = self.planmember_set.filter(ownership_type__code__in=["primary","joint"])
    return owners

But my output shows:

[<PlanMember: Name, [membership_type]><PlanMember: Name, etc etc>]

How do I go about displaying the output without the brackets, and more along the lines of:

Name [membership_type], Name [membership_type], etc

You're just returning the raw queryset from get_owners, and Python is calling repr() on that to insert it into the string.

The best bet is to do the formatting within get_owners:

def get_owners(self):
    owners = ...
    return u", ".join(unicode(o) for o in owners)

---

Your get_owners method is doing exactly what it should do: return a set of owners. In your template you can then loop over these owners and display them however you like:

{% for owner in plan.get_owners %}
    {{ owner }}
{% endfor %}

Or, inside other python code, you can compose it into a string as you like:

def __unicode__(self):
    owners = u', '.join(self.get_owners())
    label = "ID: %s, Member(s): %s, Plan Type: %s" % (self.id, owners, self.plan_type)
    return unicode(label)

Model methods shouldn't enforce display; they should only return data. (Except for obvious exceptions like __unicode__ which is specifically about how to display the model as unicode text.)

It looks like you need to add a __unicode__ method to PlanMember as you did for Plan.

def __unicode__(self):
    label = "Name: %s, [%s]" % (self.name, self.membership_type)
    return unicode(label)
