How to Handle Special Characters in Passwords When Connecting to SQLalchemy?

Connecting to SQLalchemy with Passwords Containing Special Characters

When using SQLalchemy to access a database, it is often convenient to use a connection string to specify the connection parameters. However, passwords that contain special characters can lead to errors due to delimiter interpretation.

Encoding the Password

To resolve this issue, it is necessary to URL-encode the password within the connection string. This can be achieved with the quote_plus function from the urllib.parse module:

from urllib.parse import quote_plus
from sqlalchemy.engine import create_engine

# Create a connection string with a URL-encoded password
connection_string = "postgres://user:%s@host/database" % quote_plus("p@ss")
engine = create_engine(connection_string)

This will correctly handle the special characters in the password, allowing the connection string to be successfully parsed.

Implementation in SQLAlchemy

The URL class used in SQLAlchemy for representing connection URLs also uses this encoding technique when converting them into strings. By understanding the implementation, it is possible to confidently use URL-encoded passwords in connection strings with SQLalchemy.
