flask-wtforms

问题 I'm currently using Flask-WTF v0.13.1, i have a few forms on my website, all created including the CSRF token. For some reasons i have to set a different expiration on each form, so far i could set manually the time_limit value upon creating the csrf token. I would like to update to the v0.14, according to the changelog time_limit is gone and there is no reference in the docs on how to change it anymore. Looking in the source code i saw that the form has a csrf_time_limit meta parameter. I

问题 I have a RadioField form item that uses values for its field from the database. If the database is not created I cannot start the Flask Webserver even though it should only access the database when I go to that page and load that form. If I update the database while the Webserver is running I don't see the form with the new database information. Until I restart the Flask webserver. How can I get it so that it forces the form to reload its values from the database when you visit the page. Also

问题 I am building a simple CMS that includes a profile management page. On this profile page, along with other fields, there exists a dropdown list, which I generate from a table 'parks' using the wtforms extension's QuerySelectField: from wtforms.ext.sqlalchemy.fields import QuerySelectField The rest of the fields on the profile page are populated by the 'user' table. Let assume that a user has logged in, and that their record in the 'user' table is already populated. Among the fields in the

问题 So I'm just using the FileField to add files to the server and it worked the time I tested it on Heroku (by worked I mean the image was rendering properly, granted I should be using some more proper ways to render images), but after a couple days I checked again and the image is no longer rendering properly. I checked my uploads folder and the image is not there any longer (one of the old images were). I ran the test again and the image is showing but the picture file is not in the uploads

问题 Has anyone successfully implemented CSRF protection for a form submitted with React (as a controlled component) to a Flask back-end (ideally with WTForms)? I've seen a lot of partial answers, and one with Django, but couldn't find anything definitive for Flask. My big issue seems to be that I don't know how to send the csrf token to my react front end, store it as a header before submitting my form, then submit my form with the correct token. Any direction would be really helpful. 回答1: So,
