I was going through the tutorial on the Django website.
I got this error while trying to create a Choice Object.

I dont understand what seems to be the problem. I tried changing the permissions for the "db.sqlite3" file to 777.
Thank you in advance.
You have to change permissions to the directory that database file is in too.
If running on Mac OS X, make sure to prepend the command with sudo (in the command line).

django.db.utils.OperationalError: table sabin_task has no column named title
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"

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.

In addition, this table has no data.
Can anyone help to solve this?
When I run migrate it raises this error. I can't figure out where can be the problem because it is caused by the built-in functionality of adding migration data inside the migrations table.

Do you know what to do? I can't just drop and recreate the DB.
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()

def posting_data(request):
if request.method == "POST":
response_ls = json.loads(request.POST.get('data', []))
final_ls = []
for dic in response_ls:
if dic and "csrfmiddlewaretoken" not in dic:

try:
student_record_obj = StudentRecords.objects.get(user=request.user)
student_record_obj.data = final_ls
except StudentRecords.DoesNotExist:
attrs = {'user':request.user , 'data': final_ls}
student_record_obj = StudentRecords(**attrs)
student_record_obj.save()
return redirect('/tableapp/index')
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:
import json
.
.
final_ls = json.dumps(context)
attrs = {'user':request.user , 'data': final_ls}
student_record_obj = StudentRecords(**attrs)
Hope this helps.
