Hello Django Users,
This is my first time using the admin site of Django and ran into some
trouble when i wanted to order specific columns.
What i like to do is order a foreign key related object column in the
list_display view.
I have the following code:
model:
class Subquestion(models.Model):
subquestion_id = models.AutoField(primary_key=True)
subquestion_nr = models.IntegerField()
subquestion = models.CharField(max_length=500)
question = models.ForeignKey(Question)
class Answer_Option(models.Model):
answer_option_id = models.AutoField(primary_key=True)
answer_nr = models.IntegerField()
answer = models.CharField(max_length=500)
subquestion = models.ForeignKey(Subquestion)
admin:
class Answer_OptionAdmin(admin.ModelAdmin):
def subquestion(self):
return self.subquestion.subquestion
def subquestion_question(self):
return self.subquestion.question.question
def subquestion_questionnr(self):
return self.subquestion.question.question_nr
def questionlist(self):
return
Questionlist_Question.objects.get(question=self.subquestion.question.question_id).questionlist.questionlist_name
# creating the short names displayed on the column header
subquestion_question.short_description = "Question"
subquestion_questionnr.short_description = "Question Nr"
questionlist.short_description = "Questionlist"
*subquestion_questionnr.admin_order_field = 'subquestion'*
list_display =
['answer',subquestion,subquestion_question,subquestion_questionnr,questionlist]
This code works fine but it orders based on the subquestion_id from the
Subquestion model,
I like to have it ordered based on subquestion_nr. I thought the code should
have been something like subquestion.question_nr
but this gives an error.
Does anyone know how to solve this using the django tools.
Any help is appreciated,
best regards,
Richard Mendes
