I've already pushed my Django files to Heroku via Git and now I'd like to configure at Heroku server the Postgres database. After that, I need to transfer my local sqlite database to Heroku Postgres.
All of this issue is because I don't have admin rights on my local PC (corporate unit) to install Postgres.
So basically:
1. Configure remotely Postegres at Heroku;
2. Migrate local database (sqlite) to Heroku (Postgres).
I don't know if there is another path to go on...
Thank you!
That's some crazy gymnastics you're trying to do. Getting a grasp of PostgreSQL setup is hard as it is. There are several user/table privileges you have to maintain. Sqlite3 has very simple settings in the settings.py file in Django, while Postgres requires a username, password, Host, and Port.
Also the sql you export from sqlite3, might not ingest directly into the PostgreSQL. See this. You'll have to install Postgres on your local machine, if you plan to have any sort of ok workflow as far as I can see. You can probably explore docker to create a local dev environment on your corporate PC.

I have just inherrited a jDango app with .tar.gz compression extention and a .sql file which is a postgreSQL database dump. My mission which I did not choose to accept is to somehow find its way onto AWS. I'm not familier with Django. I believe the app was built with the Ubuntu OS.
I thought that maybe the best thing would be to get postgreSQL and Django working on my local machine. I have all working in vanilla on Windows, and Ubuntu (virtual box) and have set up Amazon Lightsail with a postgreSQL database..
I'm a bit stuck as to what to do next to migrate the app. Would it all be CLI/Cmd Prompt/Terminal or is there a procedure I should be using.
I'm guessing it's not as simple as importing the database and then copying files over and replacing existing vanilla Django ones? Any pointers would be of great help. Thanks.
Open your editor terminal and write code below:
python manage.py makemigrations
python manage.py migrate
I've built an app using Django etc. I ran into a whole bunch of problems with database on Heroku after accidentally pushing to production before running heroku run python manage.py makemigrations and heroku run python manage.py migrate.
I decided to just completely destroy the database currently on Heroku and want to recommit my app's models to heroku. My hope is to completely start from a clean slate.
I just want to make sure I do this correctly so I'm asking for clear instructions about how to recommit my app's database to Heroku after destroying the database in the dashboard.
Current error I get when I open my app online is:
settings.DATABASES is improperly configured. Please supply the NAME or OPTIONS['service'] value.
Thanks!
If you completely removed your database you'll have to provision another one. Assuming you are using Heroku Postgres¹, you can do that using the Heroku CLI like so:
heroku addons:create heroku-postgresql:hobby-dev
Here we are asking Heroku to provision the heroku-postgresql add-on using the free hobby-dev tier. Modify as needed.
You can also provision add-ons using the Dashboard if you prefer.
As part of the provisioning process, Heroku Postgres will automatically set a new DATABASE_URL for your app. As long as your project was using this variable before you deleted your old database, it should find the new database without requiring any changes.
¹If you were using a different database add-on the solution should be more or less the same. Provision a new instance of the add-on, let it set its environment variable, and if your app was using that variable before it should pick it up on its own.
I am developing an app with Django and I successfully pushed it on Heroku.
This app has a postgres database and a form to allow users to fill the database.
I have coupled the local directory and Heroku, so that both if I run the server by command prompt, or if I access the app, and submit the form, my database get changed.
Now I want to make some experiments on the local database without changing the one on Heroku.
Is it possible?
Can I do it by just commenting the database URL in settings.py ?
I have searched for this matter on Google but I don't know the name it, so that I cound not find proper answer.
This is not a question of "decoupling" directories. It is because you are trying to use sqlite on Heroku, and you have added the sqlite file to your git repo.
You cannot use sqlite on Heroku; use the postgres add-on. Additionally, your sqlite file must not be in source control.
I want to migrate my django's database from MySQL to PostgreSQL.
Previously I've used database configuration options just like this example from Django website.
The MySQL engine on database setting has options: 'read_default_file', so I can separate my database credential on external file.
Now I'm ready to switch to PostgreSQL with psycopg2 engine, but I can't find the similar options like read_default_file.
Is there any solution for this?
Or may be I should change to other database engine of PostgreSQL which has this options? Thanks
read_default_file is purely a mysql thing. It cannot be used for postgresql. The closest equivalent in postgresql is the .pgpass file which is a file that needs to be created in the home directory of the user running the psql client. That defines the user's password.
When you are using django in development creating a file in your your home directory would do the trick. But in production you are not supposed to run the django dev server. Production WSGI servers run under restricted user accounts that may not have a home directory. In that case you need to use the PGPASSFILE environment variable to tell django where to look for the password.
I want to start developing a django app on heroku which uses the postgresql database. I already got my hello world django app working on heroku, but now I am wondering how to develop with the postgresql database.
How do people do this? Can I link to the heroku postgresql database in the settings.py and develop on my local 'django runserver' server?
How do people do this? Do they use a postgresql database on their own machine? How would you keep the online one and your local one the same?
I think one of the best way - it is to copy database to your local machine, but it will be hard, if you have got huge database.
You can also use working database from remote server. Just type ip/host and other settings for database on your server and you'll get access.
Not sure about python and how you interact with heroku (do you use the heroku cli??) but in the Ruby land we can do heroku db:pull which will pull the DB from heroku and magically transpose it into whatever DB you use locally, the same for pushes. It also supports individual/combintations of tables to push/pull.
