Flask 构建微电影视频网站(六)

会员模块实现

会员注册

class RegistForm(FlaskForm):
    name = StringField(
        label="昵称",
        validators=[
            DataRequired("昵称不能为空！")
        ],
        description="昵称",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入昵称！",

    )
    email = StringField(
        label="邮箱",
        validators=[
            DataRequired("邮箱不能为空！"),
            Email("邮箱格式不正确！")
        ],
        description="邮箱",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入邮箱！",
        }
    )
    phone = StringField(
        label="手机",
        validators=[
            DataRequired("手机号不能为空！"),
            Regexp("1[34578]\d{9}", message="手机格式不正确！"),

            "class": "form-control input-lg",
            "placeholder": "请输入手机！",
        }
    )
    pwd = PasswordField(
        label="密码",
        validators=[
            DataRequired("密码不能为空！")
        ],
        description="密码",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入密码！",
        }
    )
    repwd = PasswordField(
        label="确认密码",
        validators=[
            DataRequired("请输入确认密码！"),
            EqualTo('pwd', message="两次密码不一致！")
        ],
        description="确认密码",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入确认密码！",
        }
    )
    submit = SubmitField(
        '注册',
        render_kw={
            "class": "btn btn-lg btn-success btn-block",
        }
    )

    def validate_name(self, field):
        name = field.data
        user = User.query.filter_by(name=name).count()
        if user == 1:
            raise ValidationError("昵称已经存在！")

    def validate_email(self, field):
        email = field.data
        user = User.query.filter_by(email=email).count()
        if user == 1:
            raise ValidationError("邮箱已经存在！")

    def validate_phone(self, field):
        phone = field.data
        user = User.query.filter_by(phone=phone).count()
        if user == 1:
            raise ValidationError("手机号码已经存在！")

视图函数

@home.route("/regist/", methods=["GET", "POST"])
def regist():
    """
    会员注册
    """
    form = RegistForm()
    if form.validate_on_submit():
        data = form.data
        user = User(
            name=data["name"],
            email=data["email"],
            phone=data["phone"],
            pwd=generate_password_hash(data["pwd"]),
            uuid=uuid.uuid4().hex
        )
        db.session.add(user)
        db.session.commit()
        flash("注册成功！", "ok")
    return render_template("home/regist.html", form=form)

修改对应的前端文件

会员登录

class LoginForm(FlaskForm):
    name = StringField(
        label="账号",
        validators=[
            DataRequired("账号不能为空！")
        ],
        description="账号",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入账号！",
        }
    )
    pwd = PasswordField(
        label="密码",
        validators=[
            DataRequired("密码不能为空！")
        ],
        description="密码",
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "请输入密码！",
        }
    )
    submit = SubmitField(
        '登录',
        render_kw={
            "class": "btn btn-lg btn-primary btn-block",
        }
    )

视图函数

在登录时需要校验密码,需要在User模型中添加check_pwd函数,和admin模型中的一样

@home.route("/login/", methods=["GET", "POST"])
def login():
    """
    登录
    """
    form = LoginForm()
    if form.validate_on_submit():
        data = form.data
        user = User.query.filter_by(name=data["name"]).first()
        if user:
            if not user.check_pwd(data["pwd"]):
                flash("密码错误！", "err")
                return redirect(url_for("home.login"))
        else:
            flash("账户不存在！", "err")
            return redirect(url_for("home.login"))
        session["user"] = user.name
        session["user_id"] = user.id
        userlog = Userlog(
            user_id=user.id,
            ip=request.remote_addr
        )
        db.session.add(userlog)
        db.session.commit()
        return redirect(url_for("home.user"))
    return render_template("home/login.html", form=form)

在登录时添加登录日志

修改对应的前端文件

修改会员资料

        render_kw={
            "class": "btn btn-success",
        }

会员登录日志

登陆日志不需要表单

@home.route("/loginlog/<int:page>/", methods=["GET"])
@user_login_req
def loginlog(page=1):
    """
    会员登录日志
    """
    if page <= 0:
        page = 1
    page_data = Userlog.query.filter_by(
        user_id=int(session["user_id"])
    ).order_by(
        Userlog.addtime.desc()
    ).paginate(page=page, per_page=10)
    return render_template("home/loginlog.html", page_data=page_data)

新建app/templates/ui/home_page.html,用来分页

{% macro page(data,url) -%}
    {% if data %}
        <nav aria-label="Page navigation">
            <ul class="pagination">
                <li><a href="{{ url_for(url,page=1) }}">首页</a></li>

                {% if data.has_prev %}
                    <li><a href="{{ url_for(url,page=data.prev_num) }}">上一页</a></li>
                {% else %}
                    <li class="disabled"><a href="#">上一页</a></li>
                {% endif %}

                {% for v in data.iter_pages() %}
                    {% if v %}
                        {% if v == data.page %}
                            <li class="active"><a href="#">{{ v }}</a></li>
                        {% else %}
                            <li><a href="{{ url_for(url,page=v) }}">{{ v }}</a></li>
                        {% endif %}
                    {% endif %}
                {% endfor %}

                {% if data.has_next %}
                    <li><a href="{{ url_for(url,page=data.next_num) }}">下一页</a></li>
                {% else %}
                    <li class="disabled"><a href="#">下一页</a></li>
                {% endif %}

                <li><a href="{{ url_for(url,page=data.pages) }}">尾页</a></li>
            </ul>
        </nav>
    {% endif %}
{%- endmacro %}

修改对应的前端代码,并使用这个分页
