title: Flask Form, keep values after submit
body: <p>I have a flask form that has some values for a given event. On submit I redirect the user to page where I take the values from the form and calculate some statistics about the event. The user can accept these values, and submit the event to the database, or click an edit button which will take them back to the form for them to modify the values. The issue is since the form has already been submitted, when they click edit and are redirected back to the form, all the values are gone. I want the values to stay because chances are they will only be modifying one or two fields and I don't want them to have to re-enter all of them. Any ideas how to do this?</p>
