Flask-SQLAlchemy TypeError: %d format: a number is required, not str when using filter on a string f-CodePudding

I really don't have a clue of what is going on that i can't filter this query, tried filter_by() and filter() both return the same error, it is probably a stupid mistake that i'm failing to notice, your help would be really appreciated. The MariaDB(MySQL) table structure is

 -------------- -------------- ------ ----- --------- ----------------

 -------------- -------------- ------ ----- --------- ----------------

CodePudding user response：

Found the issue, the problem was on line

token = request.args.get('apitoken', '1', type=String)

The correct way is

token = request.args.get('apitoken', '1', type=str)
