Django admin: ordering inline based on FK'd property
I've got a simple Django photography competition app that has three simple model definitions:
class Person(models.Model):
name = models.CharField(unique=True, max_length=255)
id = models.AutoField(primary_key=True)
class Meta:
db_table = u'people'
def __unicode__(self):
return self.name
class Round(models.Model):
theme = models.CharField(max_length=255)
number = models.IntegerField()
id = models.AutoField(primary_key=True)
class Meta:
db_table = u'rounds'
def __unicode__(self):
return self.season.name+" - "+self.theme
class Entry(models.Model):
rank = int
total_score = models.SmallIntegerField()
id = models.AutoField(primary_key=True)
person = models.ForeignKey(Person, db_column='person')
round = models.ForeignKey(Round, db_column='round')
A Round has multiple Entry objects, and each Entry has one Person . One Person can obviously have multiple Entrys into different Rounds .
In the admin view, I'd like to be able to select a Round and see the details of the Entry items inline. This I can do with the following:
class EntryInline(admin.TabularInline):
model = Entry
fields = ['comments','person','total_score','image']
readonly_fields = ['person','image']
extra = 0
class RoundAdmin(admin.ModelAdmin):
fields = ['theme','number']
inlines = [EntryInline]
However, this sorts the Entry seemingly arbitrarily. I can use django's new ordering keyword in the EntryInline class to specify the ordering should be on the person, but this orders by the person Id property and not their name property.
How would I order this inline on the FK'd Person.name property?
将其添加到EntryInline类中：
ordering = ["person__name"]
