I tried to insert data into the table Account, but I keep getting this error message.
I delete all my migrations and make migrations again but I keep getting this error.
Here is my models.
class Student(models.Model):
user = models.OneToOneField(Account, on_delete=models.CASCADE)
name = models.CharField(max_length=50, null=True, blank=True)
phone = models.CharField(max_length=15, blank=True, null=True)
gender = models.CharField(max_length=1, choices=GENDER_CHOICES, blank=True, null=True)
section = models.ForeignKey(Section, on_delete=models.CASCADE, default=1)
dept = models.ForeignKey(Dept, on_delete=models.CASCADE, blank=True, null=True)
batch = models.CharField(max_length=15, null=True, blank=True)
USN = models.CharField(primary_key='True', max_length=100)
DOB = models.DateField(default='1998-01-01')
profile_image = models.ImageField(upload_to='student/profile_images/%Y/%m/%d/', blank=True, null=True)
address = models.CharField(max_length=300, null=True, blank=True)
nationality = models.CharField(max_length=100, null=True, blank=True)
guardian_name = models.CharField(max_length=200, null=True, blank=True)
guardian_number = models.CharField(max_length=15, null=True, blank=True)
guardian_address = models.CharField(max_length=300, null=True, blank=True)
blood_group = models.CharField(max_length=3, null=True, blank=True)
exam_name = models.CharField(max_length=300, null=True, blank=True)
background = models.CharField(max_length=300, null=True, blank=True)
passing_year = models.CharField(max_length=8, null=True, blank=True)
score = models.CharField(max_length=10, null=True, blank=True)
school_name = models.CharField(max_length=300, null=True, blank=True)
country = models.CharField(max_length=100, null=True, blank=True)
certificate = models.FileField(upload_to='certificates/%Y/%m/%d/', null=True, blank=True)
Here is Account model.
class Account(AbstractBaseUser, PermissionsMixin):
unid = models.CharField(max_length=20, unique=True, null=True, blank=True)
email = models.EmailField(verbose_name="email", max_length=60, unique=True)
username = models.CharField(max_length=30, unique=True)
is_admin = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
is_student = models.BooleanField(default=False)
is_teacher = models.BooleanField(default=False)
group = models.ForeignKey(Group, on_delete=models.CASCADE, null=True, blank=True)
user_permissions = models.ManyToManyField(
Permission,
verbose_name=_('user permissions'),
blank=True,
null=True,
help_text=_('Specific permissions for this user.'),
related_name="user_set",
related_query_name="user",
)
date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True)
last_login = models.DateTimeField(verbose_name='last login', auto_now=True)
registered = models.BooleanField(default=False)
so what I did is that when I create account if the is_student is True I create a signals that going to create student model for that account instance automatically.
here is the signals
def create_student_or_teacher(sender, created, instance, **kwargs):
if created:
if instance.is_student:
Student.objects.create(
user=instance,
USN=instance.unid,
)
elif instance.is_teacher:
Teacher.objects.create(
user=instance,
id=instance.unid,
)
So when I create the account for student the tracker will highlight in the signals Student.objects.create(...)
If you have any idea I hope it would help me.
UPDATED:
When I'm creating teacher it is working find.
here is the teacher model
class Teacher(models.Model):
name = models.CharField(max_length=50, null=True, blank=True)
phone = models.CharField(max_length=15, blank=True, null=True)
gender = models.CharField(max_length=1, choices=GENDER_CHOICES, blank=True)
salary = models.IntegerField(default=1)
school = models.ForeignKey(School, blank=True, null=True, on_delete=models.CASCADE)
section = models.ForeignKey(Section, blank=True, null=True, on_delete=models.CASCADE)
user = models.OneToOneField(Account, on_delete=models.CASCADE, null=True)
id = models.CharField(primary_key=True, max_length=100)
dept = models.ForeignKey(Dept, on_delete=models.CASCADE, blank=True, null=True)
DOB = models.DateField(default='1980-01-01')
profile_image = models.ImageField(upload_to='teacher/profile_images/%Y/%m/%d/', blank=True, null=True)
nationality = models.CharField(max_length=300, null=True, blank=True)
address = models.CharField(max_length=300, null=True, blank=True)
Finally after few hours I solved my error it was simple
in the section I set default value which was not exist
so I just change the value to an exist one and that was it.
I have a CustomUser model, and a Blog model.
CustomUser model:
class CustomUser(AbstractUser):
email = models.EmailField(unique=True)
first_name = models.CharField(max_length=20, default="", blank=True)
last_name = models.CharField(max_length=20, default="", blank=True)
address = models.CharField(max_length=150, default="", blank=True)
city = models.CharField(max_length=20, default="", blank=True)
zip_code = models.CharField(max_length=20, default="", blank=True)
country = models.CharField( max_length=50, default="", blank=True, choices=settings.COUNTRIES_LIST)
about_me = models.TextField(max_length=225, default="", blank=True)
photo_url = models.TextField(null=True)
is_active = models.BooleanField(default=True) # can login
Blog model:
class Blog(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1, null=True, verbose_name=_('user'), related_name="%(class)s_blogs", on_delete=models.SET_NULL)
blog_id = models.CharField(max_length=150, null=False, default=get_id, unique=True, editable=False)
blog_title = models.CharField(max_length=150, null=False)
blog_description = models.TextField(max_length=300, null=True, blank=True)
created_at = models.DateTimeField(auto_now=False, auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True, auto_now_add=False)
blog = FroalaField()
dynamic_link = models.CharField(max_length=225, null=False, default="")
blog_type = models.CharField( max_length=50, null=False, choices=BLOGSTYPE_LIST)
blog_status = models.CharField(max_length=150, null=False, default="unapproved")
is_active = models.BooleanField(default=False)
is_featured = models.BooleanField(default=False)
My understanding is that I could use the related_name to get all blogs by a user.
>>> from users.models import CustomerUser
>>> user = CustomUser.objects.get(pk=1)
>>> user.blog_blogs.all()
<BlogQuerySet []>
As you must have seen, this turns to always return but an empty queryset, even though there are blog entries by that user.
So is it am not understanding here?
Thank you.
This are my models
class OWNER_STORE(models.Model):
_id = models.CharField(max_length=120, unique=True, default=uuid.uuid4)
MSE_STORE_TYPE = models.ForeignKey(STORE_TYPE)
MSE_OWNER_INFO = models.ForeignKey(OWNER_INFO, related_name='STORES')
STORE_NAME = models.CharField("STORE_NAME", max_length=250, null=True, blank=True)
STORE_ID = models.IntegerField("STORE_ID", null=True, blank=True)
STORE_ADDRESS_HOUSE = models.CharField("STORE_ADDRESS_HOUSE", max_length=250, null=True, blank=True)
STORE_ADDRESS_ROAD = models.CharField("STORE_ADDRESS_ROAD", max_length=250, null=True, blank=True)
STORE_ADDRESS_VILLAGE = models.CharField("STORE_ADDRESS_VILLAGE", max_length=250, null=True, blank=True)
STORE_ADDRESS_UNION = models.CharField("STORE_ADDRESS_UNION", max_length=250, null=True, blank=True)
STORE_ADDRESS_THANA = models.CharField("STORE_ADDRESS_THANA", max_length=250, null=True, blank=True)
STORE_ADDRESS_DISTRICT = models.CharField("STORE_ADDRESS_DISTRICT", max_length=250, null=True, blank=True)
STORE_ADDRESS_DIVISION = models.CharField("STORE_ADDRESS_DIVISION", max_length=250, null=True, blank=True)
STORE_EMPLOYEE_STATUS = models.BooleanField("EMPLOYEE_STATUS")
STORE_NUMBER_OF_EMPLOYEE = models.IntegerField("NUMBER_OF_EMPLOYEE", null=True, blank=True)
STORE_AVG_REVENUE = models.IntegerField("STORE_AVG_REVENUE", null=True, blank=True)
STORE_AVG_COGS = models.IntegerField("STORE_AVG_COGS", null=True, blank=True)
STORE_AVG_PROFIT = models.IntegerField("STORE_AVG_PROFIT", null=True, blank=True)
STORE_CUSTOMER_CREDIT_LIMIT = models.IntegerField("CUSTOMER_CREDIT_LIMIT", null=True, blank=True)
STORE_BUSINESS_TARGET = models.IntegerField("BUSINESS_TARGET", null=True, blank=True)
STORE_REORDER_THRESHOLD = models.IntegerField("REORDER_THRESHOLD", null=True, blank=True)
STORE_PASSWORD = models.TextField("STORE_PASSWORD", max_length=50, default=None, null=True, blank=True)
def __str__(self):
return str(self.id)
class MSE_EMPLOYEE(models.Model):
emp_id = models.IntegerField(null=True, blank=True)
store = models.ForeignKey(OWNER_STORE)
MSE_EMPLOYEE_ID = models.IntegerField(null=True, blank=True)
MSE_EMPLOYEE_NAME=models.CharField(max_length=250, null=True, blank=True)
MSE_EMPLOYEE_MOBILE_NUMBER = models.CharField(max_length=250, null=True, blank=True)
MSE_EMPLOYEE_JOINING_DATE = models.DateField(null=True, blank=True)
MSE_EMPLOYEE_SALARY = models.IntegerField(null=True, blank=True)
def __str__(self):
return str(self.MSE_EMPLOYEE_NAME)
For my serializers.py, I did this
class STORE_EMPLOYEE_SERIALIZER(serializers.ModelSerializer):
employees = EMPLOYEE_SERIALIZER(many=True)
class Meta:
model = OWNER_STORE
fields=("MSE_STORE_TYPE", "MSE_OWNER_INFO", "STORE_NAME", "STORE_ID", "STORE_ADDRESS_HOUSE", "STORE_ADDRESS_ROAD",
"STORE_ADDRESS_VILLAGE", "STORE_ADDRESS_UNION", "STORE_ADDRESS_THANA", "STORE_ADDRESS_DISTRICT",
"STORE_ADDRESS_DIVISION", "STORE_EMPLOYEE_STATUS", "STORE_NUMBER_OF_EMPLOYEE",
"STORE_AVG_REVENUE", "STORE_AVG_COGS", "STORE_AVG_PROFIT", "STORE_CUSTOMER_CREDIT_LIMIT",
"STORE_BUSINESS_TARGET", "STORE_REORDER_THRESHOLD", "STORE_PASSWORD", "employees")
I was hoping that with a get request, I would get all the employees under store but I keep getting this error.
AttributeError: 'OWNER_STORE' object has no attribute 'employees'
and on the last line of terminal,
AttributeError: Got AttributeError when attempting to get a value for field employees on serializer STORE_EMPLOYEE_SERIALIZER.
The serializer field might be named incorrectly and not match any attribute or key on the OWNER_STORE instance.
Original exception text was: 'OWNER_STORE' object has no attribute 'employees'.
You need use MSE_EMPLOYEE_set instead employees.
Or add related_name to the store = models.ForeignKey(OWNER_STORE)
store = models.ForeignKey(OWNER_STORE, related_name='employees')
How is "translation" for following query to django queryset?
SELECT guid FROM feedme_feeditem
WHERE feed_id IN
(SELECT id FROM feedme_feed WHERE country_id IN
(SELECT id FROM feedme_country WHERE name='NL'))
models.py
class Country(models.Model):
name = models.CharField(max_length=250, blank=True)
class Category(models.Model):
name = models.CharField(max_length=250, blank=True)
slug = models.SlugField(blank=True, null=True, editable=False)
user = models.ForeignKey(User, blank=True, null=True)
country = models.ForeignKey(Country, blank=True, null=True)
class Feed(models.Model):
link = models.CharField(blank=True, max_length=450)
url = models.CharField(blank=True, max_length=450)
title = models.CharField(blank=True, null=True, max_length=250)
category = models.ForeignKey(Category, blank=True, null=True)
user = models.ForeignKey(User, blank=True, null=True)
last_update = models.DateField(blank=True, null=True, editable=False)
country = models.ForeignKey(Country, blank=True, null=True)
class FeedItem(models.Model):
title = models.CharField(max_length=350, blank=True)
link = models.URLField(blank=True)
content = models.TextField(blank=True)
feed = models.ForeignKey(Feed, blank=True, null=True)
read = models.BooleanField(default=False)
guid = models.CharField(max_length=255)
pub_date = models.DateTimeField()
To make more simple I already tried add country = models.ForeignKey(Country, blank=True, null=True) to FeedItem class but does't work how i expected.
guids = FeedItem.objects.filter(feed__country__name = 'NL')
models.py was created from legacy database.i have created a models.py and created admin.py for app interface and the app name in installed app ,i have around 76 tables (76 classes in models.py).
admin.py:
#! /usr/bin/env python
from django.contrib import admin
from django.db import models
from interface.models import Students,ApplyLeaves
site.register(ApplyLeaves)
site.register(Students)
for m in get_models(db):
site.register(m)
In above case Students and ApplyLeaves classes are not getting registerd in admin interface.
I have placed admin.pyin app directory as well as project directory,still app is not getting registered for administration
If you want to register all models into django admin, you should (although you dont have to) create an instance of the admin.
This is because, although django admin can expose all models based just on the schema alone, it has so many bells and whistels to make that schema representation meaningful real solution.
That said, in your case, you should not keep this admin.py in project level, but just at the application level. Is the Students and ApplyLeaves in the same db database you have passed to the get_models?
The elegant solution to what you are going to do would be as follows:
project-folder/bare_tables.py
from django.db.models import get_models
from django.contrib.admin import AdminSite, ModelAdmin
class BareTables(AdminSite):
pass
new_admin = BareTables(name='bare_tables')
for el in get_models():
new_admin.register(el,ModelAdmin)
In your urls.py
from bare_tables import new_admin
urlpatterns = patterns('',
(r'^bare-tables/', include(new_admin.urls)),
(r'^admin/', include(admin.site.urls)),
That way you can continue to build meaningful interfaces in /admin while you have all tables exposed in /bare-tables.
