How To Make Flask-wtf Validate Override Execute Properly

I have created a simple form which contains a URLField and StringField. As shown below: from flask_wtf import Form from wtforms.fields import StringField from wtforms.fields.html5

Solution 1:

I faced the same/similar issue where only the first conditio would be evaulated in this code

if not self.url.data.startswith("http://") or\
        self.url.data.startswith("https://"):
        self.url.data = "http://" + self.url.data

You need add () for the OR logic:

if not (self.url.data.startswith("http://") or\
        self.url.data.startswith("https://")):
        self.url.data = "http://" + self.url.data
