As stated in my question, I am now configuring my djagno project to connect with postgres. The issue i am facing is that, when making migrations, it shows me the following error:
<code>python manage.py makemigrations

i have tried literally everything, from adding psql to path to trying to install previous version of psycopg2, but to no avail. I have also ran a dozen session on chatgpt
Can someone help me with this?

The solution was actually really simple. I had been using Python 3.13, and I downgraded to Python 3.12, created a new virtualenv, and the migrations ran smoothly.
To resolve this PostgreSQL connection issue in Django you can follow this-
First, install the correct PostgreSQL database driver. Use:
<code>pip install psycopg2-binary
</code>
<code>pip install psycopg2-binary
</code>
pip install psycopg2-binary
If you prefer the regular psycopg2, you’ll need the PostgreSQL binaries installed first:
<code>pip install psycopg2
</code>
<code>pip install psycopg2
</code>
pip install psycopg2
Make sure your settings.py has the correct database configuration:
<code>DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'put_your_db_name',
'USER': 'put_your_username',
'PASSWORD': 'put_your_password', # or use from env
'HOST': 'localhost',
'PORT': '5432',
}
}
</code>
<code>DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'put_your_db_name',
'USER': 'put_your_username',
'PASSWORD': 'put_your_password', # or use from env
'HOST': 'localhost',
'PORT': '5432',
}
}
</code>
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'put_your_db_name',
'USER': 'put_your_username',
'PASSWORD': 'put_your_password', # or use from env
'HOST': 'localhost',
'PORT': '5432',
}
}
