I am using a ForeignKey called Memberno in My Django models. After entering data in the Members Class, it appears in the other classes as "member object" in the 'memberno' field. For ForeignKey, I am using 'raw_id_fields' as a workaround, but for normal fields and even 'filter_horizontal' , each memberno value is displayed as "member object". I would like the values to appear as they are in the member class i.e. 1, 2, ...
from django.db import models
# Create your models here.
class Members(models.Model):
DESIGNATION_CHOICES=(
('ADM', 'Administrator'),
('OFF', 'Club Official'),
('MEM', 'Ordinary Member'),
)
memberno = models.AutoField(primary_key=True)
fname = models.CharField(max_length=15)
sname = models.CharField(max_length=15)
onames = models.CharField(max_length=30, blank=True)
email = models.EmailField()
phoneNumber = models.CharField(max_length=15)
regNo = models.CharField(max_length=15)
designation = models.CharField(max_length=3,choices=DESIGNATION_CHOICES)
image = models.ImageField(max_length=100,upload_to='photos/%Y/%m/%d', blank=True, null=True)
course = models.CharField(max_length=30, blank=True, null=True)
def __unicode__(self):
return u'%s %s %s' % (self.fname, self.sname, self.memberno)
def get_absolute_url(self):
return '%s%s/%s' % (settings.MEDIA_URL, settings.ATTACHMENT_FOLDER, self.id)
def get_download_url(self):
return '%s%s/%s' % (settings.MEDIA_URL, settings.ATTACHMENT_FOLDER, self.name)
class Security(models.Model):
memberno = models.ForeignKey(Members, unique=True)
username = models.CharField(max_length=30, primary_key=True)
password = models.CharField(max_length=70)
def __unicode__(self):
return u'%s %s %s' % (self.username, self.password, self.memberno)
class Subscriptions(models.Model):
memberno = models.ForeignKey(Members)
receiptNo = models.CharField(max_length=30, primary_key=True)
type = models.CharField(max_length=50)
date = models.DateField()
amount = models.FloatField(max_length=99)
def __unicode__(self):
return u'%s %s %s' % (self.receiptno, self.type, self.memberno)
class events(models.Model):
eventName = models.CharField(max_length=25)
eventID = models.AutoField(primary_key=True)
details = models.TextField()
attendanceFee = models.FloatField(max_length=99)
date = models.DateField()
memberno = models.ManyToManyField(Members)
def __unicode__(self):
return u'%s %s %s' % (self.eventName, self.eventID, self.memberno)
ForeignKey is a Django ORM field-to-column mapping for creating and working with relationships between tables in relational databases.
A one-to-one relationship. Conceptually, this is similar to a ForeignKey with unique=True , but the "reverse" side of the relation will directly return a single object. In contrast to the OneToOneField "reverse" relation, a ForeignKey "reverse" relation returns a QuerySet .
The on_delete handle is used to handle the deletion of reference data to maintain the database integrity.
Django's ORM provides a way to load only specific fields from the database using only and defer methods. The deferred fields are represented with the django. db. models. base.
The admin interface appears to use __str__()
to determine the display of a model. I make it a habbit to always define both __unicode__()
and __str__()
when I create a model. For example:
class Activity(models.Model):
activity_code = models.ForeignKey(ActivityCode)
note = models.TextField(blank=True)
def __str__(self):
return "(%s) %s" % (self.activity_code.short, self.note)
def __unicode__(self):
return u'(%s) %s' % (self.activity_code.short, self.note)
Update:
It looks as though your def __unicode__(self)
is not indented properly in your code. As a result it is not a part of your class, and is not being used. Indenting is very important in Python.
I am not sure I understand your question completely, but have you defined a unicode method for your models?
