一百：CMS系统之修改密码逻辑

标签：格式   ber   val   field   逻辑   mamicode   data   class   err   

定义一个基类form，用于获取错误信息

from wtforms import Form


class BaseForm(Form):
    def get_error(self):
        # a = {‘aaa‘: [xxx], ‘bbb‘: [www]}   a.popitem()[1][0]=xxx
        message = self.errors.popitem()[1][0]  # 取第一个错误的错误信息
        return message

form验证，继承自定义的BaseForm

from wtforms import StringField, IntegerField
from wtforms.validators import Email, InputRequired, Length, EqualTo

from ..forms import BaseForm


class ResetpwdForm(BaseForm):
    oldpwd = StringField(validators=[InputRequired(message=‘请输入密码‘), Length(6, 20, message=‘密码6~20位‘)])
    newpwd = StringField(validators=[InputRequired(message=‘请输入密码‘), Length(6, 20, message=‘密码6~20位‘)])
    newpwd2 = StringField(validators=[EqualTo(‘newpwd‘, message=‘两次密码不一致‘)])


class LoginForm(BaseForm):
    email = StringField(validators=[InputRequired(message=‘请输入邮箱‘), Email(message=‘邮箱格式错误‘)])
    password = StringField(validators=[InputRequired(message=‘请输入密码‘), Length(6, 20, message=‘密码6~20位‘)])
    remember = IntegerField()

视图逻辑

class ResetPwd(views.MethodView):
    decorators = [login_required]  # 校验登录状态

    def get(self, message=None):
        return render_template(‘cms/cms_resetpwd.html‘, message=message)

    def post(self):
        form = ResetpwdForm(request.form)
        if form.validate():
            newpwd = form.newpwd.data
            oldpwd = form.oldpwd.data
            user = g.cms_user
            if user.check_password(oldpwd):
                user.password = newpwd
                db.session.commit()
                return jsonify({‘code‘: 200, ‘message‘: ‘修改成功‘})
            else:
                return jsonify({‘code‘: 400, ‘message‘: ‘旧密码错误‘})
        else:
            return jsonify({‘code‘: 400, ‘message‘: form.get_error()})


bp.add_url_rule(‘/resetpwd/‘, view_func=ResetPwd.as_view(‘resetpwd‘))
