PythonAnywhere error trying to access MySQL database (Access denied) - mysql

Question

I have setup an environment in PythonAnywhere with a simple database (new_db), following all the guides and tutorials.
I have a simple python Flask app which is trying to connect to the database using the following code:
from flask import Flask, render_template, request, redirect, url_for
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config["DEBUG"] = True
SQLALCHEMY_DATABASE_URI = "mysql+mysqlconnector://{username}:{password}#{hostname}/{databasename}".format(
username="WazzalJohn",
password="my_password_here",
hostname="WazzalJohn.mysql.pythonanywhere-services.com",
databasename="WazzalJohn$new_db>",
)
app.config["SQLALCHEMY_DATABASE_URI"] = SQLALCHEMY_DATABASE_URI
app.config["SQLALCHEMY_POOL_RECYCLE"] = 299
app.config["SQLALCHEMY_TRACK_MODIFICATIONS"] = True
db = SQLAlchemy(app)
But i keep getting the error:
ProgrammingError: (mysql.connector.errors.ProgrammingError) 1044 (42000): Access denied for user 'WazzalJohn'#'%' to database 'WazzalJohn$new_db>'
I have tried creating a new database but get the same problem. I thought PythonAnywhere handled all these types of issues so don't know what to do... has anyone had the same problem specifically on PythonAnywhere?
I have now tried to log in through a BASH console and got similar message - screen shot is here

Answer 1

In your original code, you have an error in the database name:
databasename="WazzalJohn$new_db>",
...should be:
databasename="WazzalJohn$new_db",
...without the extra ">".
The problem in the screenshot is that you're not specifying a database on the command line; you need to do something like:
mysql -u TWarren -h TWarren.mysql.pythonanywhere-services.com -p 'TWarren$default'
...where 'TWarren$default' should be replaced with the actual database name. The single quotes around the database name are important, BTW -- if you don't use them, Bash will interpret "$default" as an environment variable and mysql will try to connect to the wrong database.
