Flask view shows 400 error instead of template with form
I’m trying to display a page with a form, then add a Player to the database when the form is submitted. However, I can’t view the form because the browser always shows a 400 Bad Request error. Other posts indicate that this could be because the name of the form input doesn’t match the key I get from request.form, but all my keys match. Why do I get this error?
