I had a really tough time to get fix this issue please help if you know this.
I have a project on django, It contain model with two fields, one is of type foreign key and other one is jsonfield. When it goes to save object in database,
it doesn't get saved instead it throw exception. I don't know what's the issue is. But issue is only specific to sqlite3 database. it is working fine with other databases. I am pasting stack trace and code. it throws exception on this line
student_record_obj.save()
Stack trace:

According to the code above, final_ls variable is a list which is not insertable to database as such.
Dummp it as json string and then save it:

I have looked at a bunch of similar posts and none seem to give me the answer I need. When I try to add data to a model via the Django Admin site, it gives me this error:
IntegrityError at /admin/api/appuser/
insert or update on table "django_admin_log" violates foreign key constraint "django_admin_log_user_id_c564eba6_fk_auth_user_id"
DETAIL: Key (user_id)=(2) is not present in table "auth_user".
When I looked at my database, the table auth_user did only have one entry with user_id 1. So it does make sense that the error is thrown. However, I am not sure why it is even looking at the auth_user table in the first place because I have another table called api_appuser where my actual users are stored. In this table, there is a user with id 2. So, can anyone help me figure out why this error is being thrown and why admin.py is looking at the auth_user table in the first place? Thanks! Also, I am using Postgres as my database if that matters.

I'm Using Django with a custom user model with custom UUID and custom user manager:
class CustomUser(AbstractUser):
id = models.UUIDField(primary_key=True, default=generate_id(), editable=False)
# ...
As you can see, I'm NOT using default=uuid4(). Instead I've made a function my on my own that uses uuid() to generate the custom id also using the timestamp:
from datetime import datetime as dt
from uuid import uuid1, uuid3, uuid4
def generate_id():
timestamp = str(dt.timestamp(dt.now()))
return uuid3(uuid4(),timestamp)
Now if I open the interactive shell: python manage.py shell and I call my function several time, this is what I get:
>>> generate_id()
UUID('bd8279f1-9b4b-3d7d-8932-f9e725f17045')
>>> generate_id()
UUID('0c2ec2ad-b062-3915-a9e9-22842c6f5ea2')
>>> generate_id()
UUID('2289202b-f252-3b27-bcae-cd44825bf4e0')
>>> generate_id()
UUID('88676ea9-4902-36ac-857d-929cb133089c')
>>> generate_id()
UUID('4a18b33e-12f0-3803-8ff0-0c4f0d1c849c')
but when I try creating 2 users:
from users.models import CustomUser
>>> one = CustomUser.objects.create_user(email='hhh#jaja.com',password='JJlsaks16112')
>>> two = CustomUser.objects.create_user(email='ttth#jija.com',password='JJlsaks16112')

If I go into the database and modify the id of my first custom user, I'm able to create a second user but as you can see from the screenshot below, the ID does not change!
I guess is a caching issue. Anyone as any idea of how can I solve it? (possibly keeping my custom UUID function) Thanks.
You are calling the function, and therefore the default=… parameter [Django-doc] will be set to the result of the response, not the function, and thus indeed, each time you generate an object, it will use that result.
You thus should pass a reference to the callable, not the result:
class CustomUser(AbstractUser):
# no parenthesis ↓
id = models.UUIDField(primary_key=True, default=generate_id, editable=False)
Recently I migrated my local django + django-cms site to production server using following methods:
moved code to production server and populated db schema using makemigration and migrate commands
I exported the data using Pycharm's inbuilt database tool via "Dump data to File(s)" > "SQL-Insert-Statements.sql.groovy", the exported file had only insert statements and no other sql statement.
I copy pasted and executed these statements in query tool window using pgAdmin 4
I executed sql statements for reset sequences which I got from "python manage.py sqlsequencereset ..." command
Now after doing all this the website is working fine but on the admin side I can edit the page and it keeps the changes in database but throws error when I click on "publish page changes" button.
Here is the error:

django.db.utils.IntegrityError: duplicate key value violates unique constraint "cms_cmsplugin_path_4917bb44_uniq"
DETAIL: Key (path)=(0007) already exists.
something similar happened to me after migrating from sqlite to postgresql and I thought it was a problem with this.
But searching I found that it was a Treebeard 4.5 problem.
And the solution that worked for me was to Rollback to version 4.4.
https://github.com/django-cms/django-cms/issues/6980
on deploying my application to google app engine i encountered the following error when i try to click on the endpoints i have, is there away to solve this since i cant seem to do migrations on google app engine??

Consider this snippet:
if fire_prim is not None:
print('Fire Primary is definitely not Null, here is proof: {}'.format(fire_prim))
fire_primary_obj = LifeSafety.objects.create(
name='Fire Primary',
store=store_obj,
phone_line=fire_prim,
phone_line_provider=an_provider)
We get the following output:
Fire Primary is definitely not Null, here is proof: +16077244546

django.db.utils.IntegrityError: NOT NULL constraint failed: stores_lifesafety.phone_line
We can see with 100% certainty that the line just before object creation, fire_prim has a value of +16077244546 which should serve as the phone_line, but by the time it gets to creation its deleted somehow.
Here is my model for reference:
class LifeSafety(models.Model):
name = models.CharField(max_length=40, default='unspecified')
store = models.ForeignKey(Store, null=True, on_delete=models.SET_NULL)
phone_line = PhoneNumberField()
phone_line_provider = models.ForeignKey(Provider, null=True, on_delete=models.SET_NULL)
last_verification = models.DateTimeField(auto_now=True)
def __str__(self):
return self.name
Pre-Question:
I've allowed Null on the object and left the code to run &
unsurprisingly the objects are created, but phone_line is blank.
I am using the PhoneNumberField library.
I can "mock" this exact code from the shell & the object is created with the correct value every time.
The snippet above is exactly as shown, there is nothing in between the printing of fire_prim & the attempt at creation.
Post-Question:
Changed phone_line to a CharField rather than PhoneNumberField & the phone number is going through just fine. I'm opening an issue on their Github Repo as well.
Explicitly used the string as phone_line when creating the instance.
Verified once more that this can be done from shell without issue.
Input: LifeSafety.objects.create(name='Fire Primary', store=store, phone_line='+16077244546')
Output: LifeSafety: Fire Primary (Indicating QuerySet)
Interestingly when I do use the string explicitly on creation, the object does create with phone_line populated with that string, but I still get the error.
Input:
print('Fire Primary is definitely not Null, here is proof: {}'.format(fire_prim))
fire_primary_obj = LifeSafety.objects.create(
name = 'Fire Primary',
store = store_obj,
phone_line = '+16077244546',
phone_line_provider = an_provider
)
Output is the same stack trace as above (only name differences in diff checker).
I can go into admin and see that it was created, but I still get the NOT NULL constraint exception.
