I have Django apps, which include users and posts models. The apps work perfectly at local following making migrations and migrating. I tried two different ways to deploy the apps to Heroku. First, using Heroku Git, the apps works on Heroku the same as at local.
When using GitHub, however, all data were not brought to Heroku. I tried to run "python manage.py makemigrations" and "python manage.py migrate" on Heroku, but the data from local was not brought still.
I would really appreciate it if you could please explain and help with the issue using GitHub.
I think you have to migrate on Heroku as well, try:
heroku run python manage.py migrate
See the heroku docs
check your .gitignore file maybe db.sqlite in gitignore file and you can remove it
another option is dumpdata and load in production
you can run
python3 manage.py dumpdata > data.json
and load data in production
python3 manage.py loaddata data.json
I have a django project source code, which includes several apps. The source code have been run successfully on one environment, but when transplanted to another device, with the same postgresql version(9.4.4), python version(2.7.5), and django version(1.8.5), but the runserver reports errors like this. The database has been imported in advance.
return self.cursor.execute(sql)
django.db.utils.ProgrammingError: relation "django_migrations" already exists
Try this python manage.py migrate --fake
You can read more about it in official documentation
Try troubleshooting Initial migrations using --fake-initial
python manage.py migrate --fake-initial
https://docs.djangoproject.com/en/1.8/ref/django-admin/#django-admin-option---fake-initial
If you have an empty database you can clear all your migrations and then again run migrations and migrate command.
python manage.py makemigrations
python manage.py migrate
Good day. How do I run
py manage.py migrate
On my Google app engine instance
And how to run Django admin site after deploying. I've checked the tutorials online and most are not very clear
try:
python manage.py migrate
instead of:
py manage.py migrate
How can I run python manage.py makemigrations and python manage.py migrate automatically when deploying a Django app to Heroku via CircleCI. It seems all commands run local to CircleCI, but not on the deployed application in production.
Is there a way?
python manage.py makemigrations should be running locally, and you may commit the migration files along with the code.
Regaridng the migrations, open your Procfile and add this line: release: python manage.py migrate.
This will tell Heroku to migrate before deploying a new version of your code.
I want to create the tables of one database called "database1.sqlite", so I run the command:
python manage.py syncdb
but when I execute the command I receive the following error:
Unknown command: 'syncdb'
Type 'manage.py help' for usage.
But when I run
manage.py help
I don`t see any command suspicious to substitute
python manage.py syncdb
Version of Python I use: 3.4.2 Version of Django I use:1.9
I would be very grateful if somebody could help me to solve this issue.
Regards and thanks in advance
If you look at the release notes for django 1.9, syncdb command is removed.
Please use migrate instead. Moving forward, the migration commands would be as documented here
Please note that the django-1.9 release is not stable as of today.
Edit: Django 1.9 is stable now
the new django 1.9 has removed "syncdb",
run "python manage.py migrate",
if you are trying to create a super user, run "python manage.py createsuperuser"
$python manage.py syncdb is deprecated and not supported now.
So instead of this follow below instructions..
Whatever model you have created:
First run:
$python manage.py makemigrations
After running this command you model will be reflected in a migration.
Then you have to run:
$python manage.py migrate
Then run server:
$python manage.py runserver
Now, your project will run perfectly.
In Django 1.9 onwards syncdb command is removed. So instead of use that one, you can use migrate command,eg: python manage.py migrate.Then you can run your server by python manage.py runserver command.
Django has removed python manage.py syncdb command now you can simply use python manage.py makemigrations followed bypython manage.py migrate. The database will sync automatically.
You can run the command from the project folder as: "python.exe manage.py migrate", from a commandline or in a batch-file.
You could also downgrade Django to an older version (before 1.9) if you really need syncdb.
For people trying to run Syncdb from Visual Studio 2015:
The option syncdb was removed from Django 1.9 (deprecated from 1.7), but this option is currently not updated in the context menu of VS2015.
Also, in case you didn't get asked to create a superuser you should manually run this command to create one: python.exe manage.py createsuperuser
Run the command python manage.py makemigratons,and than python manage.py migrate to sync.
Alternarte Way:
Uninstall Django Module from environment
Edit Requirements.txt a type Django<1.9
Run Install from Requirments option in the enviroment
Try Syncdb again
This worked for me.
I also tried this command. Lastly I found the release note from django
Features removed in 1.9
The syncdb command is removed.
Djnago Releases note 1.9
I had the same problem, the only thing worked for me was this command.
python3 manage.py migrate --run-syncdb
Running this got me this result.
Ranvijays-Mac:djangodemo rana.singh$ python3 manage.py migrate --run-syncdb
