I am working on an django project. I am trying to connect django with a redshift database using postgresql_psycopg2 backend of django.
I am not able to migrate my database.
Can any one suggest relevant solutions? It will be very helpful.

I am creating a Django project where I have to use existing database data. The existing database is Postgres and it is hosted on Aws. My goal is to copy them from Aws to my local Postgres DB and use in my project.
Thanks
You can dump the database from AWS and import locally from tools like Mysql workbench
I am building a Django project with a postgresql in it. This databasa has to be populated from an API. This database doesn't have to be updated.
As I understood, the tables inside my database have to be created in my Django models. But where should I populate it?
In a script outside Django or inside my app views?
I did find a way to populate my DataBase from Django itself. I added a custom populate_db command in managment/command that runs a scritp that populate my DataBase from an external API.
Then I just have to run python3 manage.py populate_db
For some background, I worked on a Django app that had a SQLite3 database. I just created models in Django using the python manage.py startapp model_name, and just directly manipulated the database by creating API endpoints in python. I would then make API requests and change my database like that.
But this time, I've created a Django app that has a PostgreSQL database. I managed to connect my database to Django after figuring out how to install psycopg2. Then, I created a Users table in PostgreSQL through the command line. I want to get this table to show on my Django admin site, and hopefully repeat the same method for the other app. But the Django admin site can render only Django models that have been registered to the admin. So now, I'm wondering if there is a better method for working with PostgreSQL in Django.
I saw SO posts suggesting inspectdb, but this creates a large models.py file generating other classes for my app. I also couldn't successfully register the Users model to the Django admin site. I am now curious if I am working in the opposite direction. Should I be generating User models in Django and then from there, generate my PostgreSQL database?
Basically, can someone explain how to work with a PostgreSQL database in a Django app?
Can you be more specific with your question?
If you are confused on how to register the User table in django admin, you can register it in admin.py. But the method of registering depends on the type of User model you are using. You can see the docs for Custom User model.
And to get the user table in your database, you need to do migrate:
python manage.py makemigrations
python manage.py migrate
Let me know if you need any help.
I'm creating a web application on the Flask RESTful framework to serve API requests to my mobile applications. Our requirement is to integrate with the databases of different clients dynamically to access data pertinent to transactions conducted via the mobile application which also requires access to our MySQL database.
I have used MySQL queries instead of SQL Alchemy on my Flask application to interact with the database.
Is there a method to connect to multiple MySQL databases on Flask without using SQL Alchemy or having to create a new Flask server for each client?
I am learning Python / Flask. Now I am at the point where I am learning Flask with MySQL Database. I read lots of posts about using Flask with databases and most of them suggest to use SQLAlchemy. I tried to read about SQLAlchemy, but I didn't like that because I prefer building and executing SQL queries and creating tables in the database only. Is there any way that I can take full benefit of using Flask with MySQL Database without SQLAlchemy?
Please suggest.
You don't have to use SQLAlchemy, no. You just have to connect to the database in Flask and execute your queries manually.
This question is about how to connect to MySQL with Python, and the official docs go over creating a site with a SQLite database. Modify the examples provided there with your MySQL connection.
