flask_wtf在import的时候如果写成:

from flask_wtf import Form

flask在运行的时候会有警告信息:

FlaskWTFDeprecationWarning: "flask_wtf.Form" has been renamed to "FlaskForm" and will be removed in 1.0...

修改为:

from flask_wtf import FlaskForm

即可正常,相应的class也要从Form改成FlaskForm如:

class LoginForm(FlaskForm):

即可去除FlaskWTFDeprecationWarning: "flask_wtf.Form" has been renamed to "FlaskForm" and will be removed in 1.0警告信息。

带符号 * 的表示必填项
