Flask-WTF-Decorators is easy to use. You can define a view that requires
validation.
from flask-wtf-decorators import FormValidator
form_validator = FormValidator()
@form_validator.validate_form(TestForm)
@app.route('/', methods=['GET', 'POST'])
def index(form):
pass
You can tell Flask-WTF-Decorators what to do when a form is illegal.
To do this you should provide a callback for error_handler.
@form_validator.error_handler
def error_handler(errors):
return jsonify({'errors': errors}), 400
