For the whole form, form.errors
contains a map of fields to lists of errors. If it is not empty, then the form did not validate. For an individual field, field.errors
contains a list of errors for that field. The list is the same as the one in form.errors
.
form.validate()
performs validation and populates errors
. When using Flask-WTF, form.validate_on_submit()
performs an additional check that request.method
is a "submit" method, which mostly means it is not a GET
request.
