Flask开发微电影网站(四)

会员中心页面，如下图所示

用户登录后，修改密码页面，如下图所示

用户查看自己的评论页面，如下图所示

用户查看自己的登录日志页面，如下图所示

用户查看自己收藏的电影的页面，如下图所示

1. 定义用户主页面左侧部分

在上面的图片里，可以看到，整个页面的顶部和左侧都是一样的

在之前，已经把顶部部分单独定义在templates目录的home目录下

这里可以把用户主页的左侧也单独定义一个文件menu.html，然后让包含左侧部分的页面引入menu.html页面

menu.html页面的内容：

<div class="col-md-3">
    <div class="list-group">
        <a id='m-1' href="{{ url_for('home.user') }}" class="list-group-item">
            <span class="glyphicon glyphicon-user"></span>&nbsp;会员中心
        </a>
        <a id='m-2' href="{{ url_for('home.pwd') }}" class="list-group-item">
            <span class="glyphicon glyphicon-lock"></span>&nbsp;修改密码
        </a>
        <a id='m-3' href="{{ url_for('home.comments',page=1) }}" class="list-group-item">
            <span class="glyphicon glyphicon-comment"></span>&nbsp;评论记录
        </a>
        <a id='m-4' href="{{ url_for('home.loginlog',page=1) }}" class="list-group-item">
            <span class="glyphicon glyphicon-calendar"></span>&nbsp;登录日志
        </a>
        <a id='m-5' href="{{ url_for('home.moviecol',page=1) }}" class="list-group-item">
            <span class="glyphicon glyphicon-heart"></span>&nbsp;收藏电影
        </a>
    </div>
</div>

2. 定义用户登录后的主页面代码

2.1 在home目录下的forms.py文件中，定义用户主页显示用户详细信息的表单类UserdetailForm

可以通过调用UserdetailForm表单类直接在前端页面上渲染生成用户详细信息的字段标签

from flask_wtf import FlaskForm
from wtforms.fields import StringField, PasswordField, SubmitField, FileField, TextAreaField
from wtforms.validators import DataRequired, EqualTo, Email, Regexp, ValidationError

from app.models import User

class UserdetailForm(FlaskForm):
    name = StringField(
        label="呢称",
        validators=[
            DataRequired("请输入呢称！")
        ],
        description="呢称",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入呢称！"
        }
    )
    email = StringField(
        label="邮箱",
        validators=[
            DataRequired("请输入邮箱！"),
            Email("邮箱的格式不正确，请重新输入！")
        ],
        description="邮箱",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入邮箱！"
        }
    )
    phone = StringField(
        label="手机号",
        validators=[
            DataRequired("请输入手机号！"),
            Regexp("1[34578]\d{9}", message="输入的手机号格式不正确！"),
        ],
        description="手机号",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入手机号！"
        }
    )
    face = FileField(
        label="头像",
        validators=[
            DataRequired("请上传头像！")
        ],
        description="头像"
    )
    info = TextAreaField(
        label="简介",
        validators=[
            DataRequired("请输入简介！")
        ],
        description="简介",
        render_kw={
            "class": "form-control",
            "rows": "10"
        }
    )
    submit = SubmitField(
        "保存修改",
        render_kw={
            "class": "btn btn-success",
        }
    )

2.2 定义用户主页面的视图函数user

@home.route("/user/", methods=['GET', 'POST'])
def user():
    form = UserdetailForm()
    user = User.query.get(int(session.get("user_id")))
    form.face.validators = []
    if request.method == 'GET':
        form.name.data = user.name
        form.email.data = user.email
        form.phone.data = user.phone
        form.info.data = user.info

    if form.validate_on_submit():
        data = form.data
        file_face = secure_filename(form.face.data.filename)
        if not os.path.exists(app.config['FC_DIR']):
            os.makedirs(app.config['FC_DIR'])
            os.chmod(app.config['FC_DIR'])
        user.face = change_filename(file_face)
        form.face.data.save(app.config['FC_DIR'] + user.face)

        name_count = User.query.filter_by(name=data.get("name")).count()
        if data.get("name") != user.name and name_count == 1:
            flash("用户名已经存在,请重新输入！", "err")
            return redirect(url_for("home.user"))
        email_count = User.query.filter_by(email=data.get("email")).count()
        if data.get("email") != user.email and email_count == 1:
            flash("邮箱已经存在，请重新输入！", "err")
            return redirect(url_for("home.user"))

        phone_count = User.query.filter_by(phone=data.get('phone')).count()
        if data.get("phone") != user.phone and phone_count == 1:
            flash("手机号已经存在，请重新输入！", "err")
            return redirect(url_for("home.user"))

        user.name = data.get("name")
        user.email = data.get("email")
        user.phone = data.get("phone")
        user.info = data.get("info")
        db.session.add(user)
        db.session.commit()
        flash("修改已经保存！", "ok")
        return redirect(url_for("home.user"))
    return render_template("home/user.html", form=form, user=user)

2.3 定义用户主页的前端页面

{% extends "home/home.html" %}

{% block css %}
    <style>
        .col-lg-1, .col-lg-10, .col-lg-11, .col-lg-12, .col-lg-2, .col-lg-3, .col-lg-4, .col-lg-5, .col-lg-6, .col-lg-7,
        .col-lg-8, .col-lg-9, .col-md-1, .col-md-10, .col-md-11, .col-md-12, .col-md-2, .col-md-3, .col-md-4, .col-md-5,
        .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-sm-1, .col-sm-10, .col-sm-11, .col-sm-12, .col-sm-2, .col-sm-3,
        .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-xs-1, .col-xs-10, .col-xs-11, .col-xs-12,
        .col-xs-2, .col-xs-3, .col-xs-4, .col-xs-5, .col-xs-6, .col-xs-7, .col-xs-8, .col-xs-9 {
            padding-right: 3px;
            padding-left: 3px;
        }
    </style>
{% endblock %}

{% block content %}
    {% include "home/menu.html" %}
    <div class="col-md-9">
        <div class="panel panel-warning">
            <div class="panel-heading">
                <h3 class="panel-title"><span class="glyphicon glyphicon-map-marker"></span>&nbsp;会员中心</h3>

{% endblock %}

3. 定义用户修改密码的页面代码

3.1 在home目录下的forms.py文件中，定义用户修改密码的表单类PwdForm

可以通过调用PwdForm表单类直接在前端页面上渲染生成用户修改密码需要的字段标签

from flask_wtf import FlaskForm
from wtforms.fields import StringField, PasswordField, SubmitField, FileField, TextAreaField
from wtforms.validators import DataRequired, EqualTo, Email, Regexp, ValidationError

class PwdForm(FlaskForm):
    old_pwd = PasswordField(
        label="旧密码",
        validators=[
            DataRequired("请输入旧密码!")
        ],
        description="旧密码",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入旧密码!"
        }
    ),
    new_pwd = PasswordField(
        label="新密码",
        validators=[
            DataRequired("请输入新密码!")
        ],
        description="新密码",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入新密码!"
        }
    )
    submit = SubmitField(
        "修改密码",
        render_kw={
            "class": "btn btn-success"
        }
    )

3.2 定义用户修改密码的视图函数pwd

@home.route("/pwd/", methods=['GET', 'POST'])
def pwd():
    form = PwdForm()
    if form.validate_on_submit():
        data = form.data
        user = User.query.filter_by(name=session.get("user")).first()
        if not user.check_pwd(data.get("pwd")):
            flash("旧密码输入错误，请重新输入！", "err")
            return redirect(url_for("home.pwd"))

        from werkzeug.security import generate_password_hash
        user.pwd = generate_password_hash(data.get("new_pwd"))
        db.session.add(user)
        db.session.commit()
        flash("修改密码成功，请重新登录！", "ok")
        return redirect(url_for("home.logout"))
    return render_template("home/pwd.html", form=form)

3.3 定义用户修改密码的前端页面的代码

{% extends "home/home.html" %}

{% block content %}

{% block css %}
<style>
    .col-lg-1, .col-lg-10, .col-lg-11, .col-lg-12, .col-lg-2, .col-lg-3, .col-lg-4, .col-lg-5, .col-lg-6, .col-lg-7, .col-lg-8, .col-lg-9, .col-md-1, .col-md-10, .col-md-11, .col-md-12, .col-md-2, .col-md-3, .col-md-4, .col-md-5, .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-sm-1, .col-sm-10, .col-sm-11, .col-sm-12, .col-sm-2, .col-sm-3, .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-xs-1, .col-xs-10, .col-xs-11, .col-xs-12, .col-xs-2, .col-xs-3, .col-xs-4, .col-xs-5, .col-xs-6, .col-xs-7, .col-xs-8, .col-xs-9{
            padding-right: 3px;
            padding-left: 3px;
        }
</style>
{% endblock%}

{% include "home/menu.html" %}
<div class="col-md-9">
        <div class="panel panel-warning">
            <div class="panel-heading">
                <h3 class="panel-title"><span class="glyphicon glyphicon-map-marker"></span>&nbsp;会员中心</h3>
            </div>
            <div class="panel-body">
                <form role="form">
                    <fieldset>
                            <div class="form-group">
                                <label for="input_oldpwd"><span class="glyphicon glyphicon-lock"></span>&nbsp;旧密码</label>
                                <input id="input_oldpwd" class="form-control" placeholder="旧密码" name="oldpwd" type="password" autofocus>
                            </div>

                            <div class="form-group">
                                <label for="input_newpwd"><span class="glyphicon glyphicon-lock"></span>&nbsp;新密码</label>
                                <input id="input_newpwd" class="form-control" placeholder="新密码" name="newpwd" type="password" autofocus>
                            </div>
                            <div class="col-md-12" id="error_newpwd"></div>
                            <a href="login.html" class="btn btn-success"><span class="glyphicon glyphicon-edit"></span>&nbsp;修改密码</a>
                        </fieldset>
                </form>
            </div>
        </div>
    </div>
{% endblock %}
{% block js %}
<script>
    $(document).ready(function(){
       $('#m-2').addClass('active')
    });
</script>
{% endblock %}

4. 定义用户查看自己评论的页面代码

4.1 定义用户查看自己评论的视图函数

由于每个用户的电影评论数可能有很多，这许多的评论不可能在一个页面上全部显示完成，所以要进行分页，默认显示第一页的评论内容

@home.route("/comments/<int:page>/")
def comments(page=None):
    if page is None:
        page = 1
    page_data = Comment.query.join(Movie).join(User).filter(
        Movie.id == Comment.movie_id,
        User.id == session["user_id"]
    ).order_by(Comment.id).paginate(page=page, per_page=10)
    return render_template("home/comments.html", page_data=page_data)

4.2 定义用户查看自己的评论的前端页面代码

{% extends "home/home.html" %}

5. 定义用户登录日志部分代码

5.1 定义用户查看自己的登录日志的视图函数

每个用户登录的次数可以有很多，所以要进行分页，默认显示第一页的登录日志

@home.route("/loginlog/<int:page>/", methods=['GET'])
def loginlog(page=None):
    if page is None:
        page = 1
    page_data = Userlog.query.filter_by(user_id=int(session.get("user_id"))).order_by(
        Userlog.id
    ).paginate(page=page, per_page=10)

    return render_template("home/loginlog.html", page_data=page_data)

5.2 定义用户查看自己的登录日志的前端页面代码

{% extends "home/home.html" %}
{% import "ui/home_page.html" as pg %}

{% block css %}
    <style>
        .col-lg-1, .col-lg-10, .col-lg-11, .col-lg-12, .col-lg-2, .col-lg-3, .col-lg-4, .col-lg-5, .col-lg-6, .col-lg-7,
        .col-lg-8, .col-lg-9, .col-md-1, .col-md-10, .col-md-11, .col-md-12, .col-md-2, .col-md-3, .col-md-4, .col-md-5,
        .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-sm-1, .col-sm-10, .col-sm-11, .col-sm-12, .col-sm-2, .col-sm-3,
        .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-xs-1, .col-xs-10, .col-xs-11, .col-xs-12,
        .col-xs-2, .col-xs-3, .col-xs-4, .col-xs-5, .col-xs-6, .col-xs-7, .col-xs-8, .col-xs-9 {
            padding-right: 3px;
            padding-left: 3px;
        }
    </style>
{% endblock %}

{% block content %}
    {% include "home/menu.html" %}
    <div class="col-md-9">
        <div class="panel panel-warning">
            <div class="panel-heading">
                <h3 class="panel-title"><span class="glyphicon glyphicon-map-marker"></span>&nbsp;登录日志</h3>
            </div>
            <div class="panel-body">
                <table class="table table-bordered">
                    <tr>
                        <td style="10%">编号</td>
                        <td style="30%">登录时间</td>
                        <td style="30%">登录IP</td>
                    </tr>
                    {% for v in page_data.items %}
                        <tr>
                            <td>{{ v.id }}</td>
                            <td>{{ v.addtime }}</td>
                            <td>{{ v.ip }}</td>
                        </tr>
                    {% endfor %}

                    {{ pg.page(page_data,'home.loginlog') }}
                </div>
            </div>
        </div>
    </div>

{% endblock %}

{% block js %}
    <script>
        $(document).ready(function () {
            $("#m-4").addClass("active");
        });
    </script>
{% endblock %}

6. 定义用户查看自己的电影收藏的部分的代码

6.1 定义用户查看自己收藏的电影的视图函数

当用户收藏的电影可能有很多，所以需要进行分页，默认显示第一页的内容

@home.route("/moviecol/<int:page>/")
def moviecol(page=None):
    if page is None:
        page = 1
    page_data = Moviecol.query.join(Movie).join(User).filter(
        Movie.id == Moviecol.movie_id,
        User.id == session.get("user_id")
    ).order_by(Moviecol.id).paginate(page=page, per_page=10)
    return render_template("home/moviecol.html", page_data=page_data)

6.2 定义用户查看自己收藏的电影的前端页面代码

{% extends "home/home.html" %}
{% import "ui/home_page.html" as pg %}
{% block css %}
    <style>
        .col-lg-1, .col-lg-10, .col-lg-11, .col-lg-12, .col-lg-2, .col-lg-3, .col-lg-4, .col-lg-5, .col-lg-6, .col-lg-7,
        .col-lg-8, .col-lg-9, .col-md-1, .col-md-10, .col-md-11, .col-md-12, .col-md-2, .col-md-3, .col-md-4, .col-md-5,
        .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-sm-1, .col-sm-10, .col-sm-11, .col-sm-12, .col-sm-2, .col-sm-3,
        .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-xs-1, .col-xs-10, .col-xs-11, .col-xs-12,
        .col-xs-2, .col-xs-3, .col-xs-4, .col-xs-5, .col-xs-6, .col-xs-7, .col-xs-8, .col-xs-9 {
            padding-right: 3px;
            padding-left: 3px;
        }
    </style>
