"no such table" exception

In Django, I’ve added some models into models.py. After manage.py makemigrations, manage.py migrate raised this exception:

django.db.utils.OperationalError: no such table:

I removed all old migrations and run makemigrations and migrate again which seemed to work. It didn’t help because when I click on User customer profiles of User translator profiles it raises exception:

Where is the problem?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

I solved the same problem with these steps :

  • Delete your database (db.sqlite3 in my case) in your project directory
  • Remove everything from __pycache__ folder under your project subdirectory
  • For the application you are trying to fix, go to the folder and clear migrations and __pycache__ directories

When you are sure you have cleared all the above files, run:

python manage.py makemigrations
python manage.py migrate

I hope this helps.

Solution 2

run below command. It solves me once this issue

manage.py migrate –run-syncdb

Solution 3

Another case wihch can generate the no such table error. If your views.py or similar executes code that tries to access the DB when imported, i.e. importing views.py has side effects, then starting from scratch won’t work.

This happens when your code was working with an existing DB, and now you’re trying to start without a DB. Just change views.py so it can be imported without side effects. If you don’t want to fix the design, do something like:

from django.db.utils import OperationalError
format_list = [('', '(all)')]
geom_type_list = [('', '(all)')]
        for i in Format.objects.values_list('name')])
        for i in Geom_type.objects.values_list('name')])
except OperationalError:
    pass  # happens when db doesn't exist yet, views.py should be
          # importable without this side effect

Solution 4

To solve it I did this (on Ubuntu, you’ll need to adapt the commands for Windows):

1. Remove all the migration files

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete

find . -path "*/migrations/*.pyc"  -delete

2. Delete db.sqlite3

rm db.sqlite3

3. Create and run the migrations:

python manage.py makemigrations
python manage.py migrate

4. Sync the database:

manage.py migrate --run-syncdb

Bit of a pain as you need to delete your database, but fine for a test system.
Got all but the final step from this generally excellent resource: https://simpleisbetterthancomplex.com/tutorial/2016/07/26/how-to-reset-migrations.html

Solution 5

Using Django, I had to perform:

python manage.py migrate --run-syncdb

Solution 6

Adding to terry_brown’s answer, this is what cause my problems. I had a custom user model with ForeignKey to another model. And I set defaults to first object in the DB. It worked when I had the data in the database. But when I started from scratch, it didn’t work because it was executed immediately when imported (so not even migration went through).

class User(AbstractBaseUser, PermissionsMixin):
    subscription_plan = models.ForeignKey(SubscriptionPlan, default=SubscriptionPlan.objects.first().id)

I had to sacrifice that default (commenting it out).

A better solution would be to prepopulate your database with initial migration or fixtures.

Solution 7

Follow this steps to get fixed this issue.

python manage.py migrate --fake APPNAME zero

This will make your migration to fake. Now you can run the migrate script

python manage.py migrate APPNAME


python manage.py migrate

Tables will be created and you solved your problem.. Cheers!!!

Solution 8

I read the above Answers given by other teams.
Majorly were asking to delete SQLite(DB) and reset the "migrations" folder.

If you are working in a production environment then this will not be the right choice.

  1. python manage.py migrate --fake APPNAME zero
  2. python manage.py migrate APPNAME
  3. python manage.py makemigrations APPNAME
  4. python manage.py migrate APPNAME

These four steps are enough to solve this issue.

Solution 9

This error is happening because of the database of Django , this is not user fault. Its easiest solution is create new app with different name .Then create same models and then run python manage.py makemigrations and then migrate. By doing this your error should be solved

Solution 10

I faced the same problem. I removed all migrations and run this command

python manage.py makemigrations
python manage.py migrate --run-syncdb

It worked for me and the data was also safe (I didn’t lose any)

Solution 11

While running any management command “django.contrib.admin” automatically attempts to discover and admin.py modules in installed apps.

If there is a code related to database, it runs automatically and tries to load data from database when it can not find data related table in database throw this Error.

To fix this error just change "django.contrib.admin" in INSTALLED_APPS to "django.contrib.admin.apps.SimpleAdminConfig", it will prevent “django.contrib.admin” from auto discovering and running admin modules.

django.contrib.admin automatically performs auto discovery of admin modules in installed applications. To prevent it, change your INSTALLED_APPS to contain ‘django.contrib.admin.apps.SimpleAdminConfig’ instead of ‘django.contrib.admin’.


Solution 12

You don’t need views to makemigrations. Comment out all references to other apps from urls.py, clear db and old migrations, run makemigrations, and comment your urls.py back in. Worked for me.

Solution 13

I had the same problem.
None of the above solutions worked for me.
It all probably started when I added a new model, had a few objects in the database and then I changed model’s name.
I needed to delete the whole model from my app and then run app’s admin page. Then I restored the model by clicking ctrl + z in all files from which I deleted it and finally I was able to run makemigrations and migrate commands.

Solution 14

I was facing the same error. The steps I used to solve this issue is:

  1. Make sure that there’s migrations folder inside your app. If there isn’t any, create the migrations folder inside the app folder, and then create __init__.py file inside the folder.

  2. If the migrations folder is already there, then delete all the migration files.

  3. Delete the database file which is by default db.sqlite3.

  4. Run the command python manage.py makemigrations

  5. python manage.py migrate

Solution 15

Maybe out of time but…I have same problem when I tried to “clone” Django 1.11 installation into other directory and then with initial try to manage makemigrations.

I solve the problem following way:

  1. settup initial Django installation and creating main application by:

django-admin.py startproject app_name

  1. initial migrations
    manage makemigrations, manage migrate

  2. Setup the superuser:

manage createsuperuser

  1. copy all files and directories (Django applications) except the urls.py and settings.py in main directory

  2. Added all apps into INSTALLED_APPS

  3. manage makemigrations, manage migrate

  4. Copied settings.py and urls.py from source Django application directory

Thats it no errors and all is working fine.


Solution 16

If someone else has this problem and the accepted solution is not working, have a look at your db path,
the db path should be absolute path,

'NAME': '/pathto-db/default.db',


Solution 17

If none of the above solution worked for you then add the appname along with the makemigration and migrate command.

 makemigration login
 migrate login

That might help you to figure out the problem.

Solution 18

I got this error while creating a model.
I opened the db.sqlite3 file and created a table for the model using SQLite DB Browser. Then I created a migration and fake migrated it. Don’t know what caused the issue but this workaround helped.

Solution 19

would you delete a production bank?
I saw that many have the sqlite deleted, but if it is a production bank?

solution to delete data from django_migrations table less contenttypes

already in the table django_content_type you remotely app_label

inside the migrations folder deletes everything but init.py

python manage.py makemigrations

python manage.py migrate –fake

that’s how I solved the app duplication problems (I had two apps with the same name after installing a plugin) and django created the missing tables, among other things.

in my normally functional case

Solution 20

With same error and without removing database:

  • remove migrations
  • remove __pychache__
  • python manage.py makemigrations --empty alias
  • python manage.py makemigrations alias
  • python manage.py migrate alias zero
  • remove again migrations
  • remove again __pycache__
  • python manage.py makemigrations
  • python manage.py migrate alias zero

Where alias is the app name.

Solution 21

If you have deleted the DB and migrating now this will happens.

For eg if your error says no such table table1 then

  • python manage.py makemigrations
  • python manage.py migrate
  • python manage.py table1 app1

Here table1 is the name of the table and app1 is the Django app name where the table1 model exists.

Solution 22

I know this commonly solved by deleting de sqlite3 DB that is used in the development process.

Also, I know this question is currently solved, but I want to leave my case here as an alternative.

Sometimes while we are programming we change a lot of things in our models. When we run python manage.py makemigrations a file is created inside of our app folder/migrations. And when we run python manage.py migrate a record in the table django_migrations is created. this record contains 3 fields we must check in detail:

  • 1 – name (this is the file name created in the migrations app folder)
  • 2 – app (this is the name of our app. Also works like a namespace to prevent conflicts)
  • 3 – applied (this is the date-time when the migration was executed).

If you’ve modified your model previously, you should have several files inside migrations (amount accordingly with the times you’ve executed makemigrations on every change), in my case I wanted to erase these files just to have only one migration file.

The problem with this is that when makemigrations was run again it creates a file 0001_initial.py. If you remember the table django_migrations contains a log of this file, this is to prevent the execution of migrations that already have been done.

If this is your case, you would erase the records of your app migrations from this table.

Solution 23

I did some alterations in my database and was facing the same issue. None of solutions worked for me so after spending hours i finally decided to delete the "db.sqlite3" file and runs the makemigrations and migrate commands. After it worked fine. But this solution is not a good one to use immediately, use it only when you are out of options.

Solution 24

Maybe migrations Folder was not created:

python manage.py makemigrations app_name
python manage.py migrate 

Solution 25

The only way to fix my error was commenting out every single file. This error might occur while a file thinks the database is not empty, or that it actually exists.

I just commented out the entire project, migrated, uncommented the models.py file, migrated again, uncommented the entire project. I have no idea why it worked.

Note: Use and implement solution 1 because this method fully tested our system.
