小编Ben*_*min的帖子

我开始将 Babel 与 WTForms 和 Flask 一起使用。下面我尝试 gettext 我的用户名和密码的占位符关键字字段的占位符关键字：

#!/usr/bin/env python\n# -*- coding: utf-8 -*-\n\nfrom flask_babel import gettext\nfrom flask_wtf import FlaskForm\nfrom wtforms import PasswordField, StringField\nfrom wtforms.validators import DataRequired\n\n\nclass LoginForm(FlaskForm):\n    username = StringField(label=\'username\',\n                           validators=[DataRequired()],\n                           render_kw={"placeholder": gettext(\'Username\')})\n    password = PasswordField(label=\'password\',\n                             validators=[DataRequired()],\n                             render_kw={"placeholder": gettext(\'Password\')})\n
