Hi i have a django model as below:
from django.db import models
class ClientProfile(models.Model):
id = models.AutoField(primary_key=True)
firstname = models.CharField(max_length=100,blank=False)
lastname = models.CharField(max_length=100,blank=False)
gender = models.CharField(max_length=6,blank=False)
birthdate = models.DateField(blank=False)
nationality = models.CharField(max_length=100,blank=False)
education = models.CharField(max_length=100,blank=True)
occupation = models.CharField(max_length=100,blank=True)
i have created this model with email field initially. but then i decided to deduct it.
now i get this error when i migrate:
django.db.utils.OperationalError: near "AUTOINCREMENT": syntax error
and then i deleted my database and migrated again and i get the same message again. I tried deleting my app view and then start from scrach(creating a new migration and creating a new superuser and then add the model again) and still got the same error. i even tried rollback to initial migrations and then migrate again but got the email field back again and the new migration didn't change it. what can i do?
and these are my migrations:
and this is my stacktrace:

Try without id = models.AutoField(primary_key=True), which is redundant as Django automatically assigns a primary key named id if you don't specify a different primary key.
If it still fails, show the code from the migration file.

I just deleted the junk file inside the migrations>pycache
In your pageinfo model, it looks like you have
subscriber=models.CharField(max_length=15,null=True);
Try increasing the max_length for this field and re run your makemigrations and migrate command.
The error is due to already saved data in your database being longer than the given characters. You may want to look at the data and consider fixing it or whether the given characters are really the limit you want.
If you are maintaining history for the model then you also need to delete data in the history table.
I Am doing a project in Django and I have created some models in my project and after migrating it gives me something error like Django.db.utils.OperationalError: no such table: Recruiter_jobs, but I think I have all the tables registered in admin also. but still, it showing an error...

(env) PS C:\Users\ashwi\Documents\GitHub\AMCH\AMCH_Recruiter>
what's the error cause here? I have even tried to delete this model but still no changes... it gives the same error.
please suggest any solution for it.
I'm trying to store an ArrayField in a Django model called User, I'm using MongoDB and Djongo.
I managed to do it with one model called Pair, I can store a list of Pairs and store that list in a User model using ArrayField which was fairly simple, I just followed this example from Djongo's official doc
Now I'm trying to store another list but for some reason, it just keeps giving me a huge TraceBack (90 lines) with an ambiguous error: 'django.db.utils.DatabaseError'
here's my user model:
class User(AbstractBaseUser):
email = models.EmailField(verbose_name='email address', max_length=127, unique=True)
first_name = models.CharField(verbose_name='First Name', max_length=30, blank=True)
last_name = models.CharField(verbose_name='Last Name', max_length=30, blank=True)
is_active = models.BooleanField(default=True, verbose_name='Active')
is_admin = models.BooleanField(default=False, verbose_name='Admin')
pairs = models.ArrayField (
model_container=Pair,
null=True
)
conversations = models.ArrayField(
model_container=Conversation,
null=True
)
again, the pairs attribute is working just fine but the conversation is not
The Pair model
class Pair(models.Model):
name = models.CharField(max_length=16)
purchase_price = models.DecimalField(verbose_name='Purchase price', max_digits=20, decimal_places=6)
class Meta:
ordering = ['name']
abstract=True
The Conversation model
class Conversation(models.Model):
handle = models.CharField(max_length=255)
class Meta:
abstract = True
and this is the traceback:

Note: when I run python manage.py migrate, migrations are created with no problem, but when I apply them, I get the above error
Problem solved!
turned out that there's a problem with Djonogo specifically in this file djongo/sql2mongo/query.py
this question has already been answered in this comment on the djongo Github page

I'm using the following modules and MySQL version:
Django 2.1.5
mysqlclient 1.3.14
MySQl 5.1.7.3 Community edition
Anyone that can help me out?
I've found and solved the problem. The table I'm referencing to (allmodusers) was still using the MyISAM database engine. I've changed the database engine of this table to InnoDB after reading the following article: https://kinsta.com/knowledgebase/convert-myisam-to-innodb/.
