十一、用户信息

11.1.个人信息展示

 （1）新建‘usercenter-bae.html’当母板

 

(2)修改‘usercenter-info.html’继承usercenter-bae.html

 

（3）配置urls

MxOnline/urls.py

　　#个人信息
    path("users/", include('users.urls', namespace="users")),

users/urls.py

from django.urls import path,include,re_path
from .views import UserinfoView

app_name = 'users'

urlpatterns = [
    #用户信息
    path("info/", UserinfoView.as_view(),name='user_info'),
]

users/views.py

class UserinfoView(LoginRequiredMixin,View):
    '''用户个人信息'''
    def get(self,request):
        return render(request,'usercenter-info.html',{})

然后访问http://127.0.0.1:8000/users/info/  看看能不能正常显示

（4）显示个人信息

<ul class="right">
                        <li>昵&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;称：

                        </li>
                        <li class="p_infor_city">地&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;址：
                            <input type="text" name="address" id="address" placeholder="请输入你的地址" value="{{ request.user.adress }}" maxlength="10">
                            <i class="error-tips"></i>
                        </li>
                        <li>手&nbsp;&nbsp;机&nbsp;&nbsp;号：
                            <input type="text" name="mobile" id="mobile" placeholder="请输入你的手机号码" value="{{ request.user.mobile|default_if_none:'' }}" maxlength="10">
                        </li>
                        <li>邮&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;箱：
                            <input class="borderno" type="text" name="email" readonly="readonly" value="{{ request.user.email }}"/>
                            <span class="green changeemai_btn">[修改]</span>
                        </li>
                        <li class="button heibtn">
                            <input type="button" id="jsEditUserBtn" value="保存">
                        </li>
                    </ul>

说明：
　　{{ request.user.mobile|default_if_none:'' }}   如果字段没有值，值默认为空字符串

 

 

11.2.修改用户图像

 (1)url

#用户图像上传
    path("image/upload", UploadImageView.as_view(),name='image_upload'),

(2)urers/forms.py

class UploadImageForm(forms.ModelForm):
    '''用户更改图像'''
    class Meta:
        model = UserProfile
        fields = ['image']

(3)views.py

class UploadImageView(LoginRequiredMixin,View):
    '''用户图像修改'''
    def post(self,request):
        #上传的文件都在request.FILES里面获取，所以这里要多传一个这个参数
        image_form = UploadImageForm(request.POST,request.FILES)
        if image_form.is_valid():
            image = image_form.cleaned_data['image']
            request.user.image = image
            request.user.save()
            return HttpResponse('{"status":"success"}', content_type='application/json')
        else:
            return HttpResponse('{"status":"fail"}', content_type='application/json')

(4)前端页面

<iframe id='frameFile' name='frameFile' style='display: none;'></iframe>

<form class="clearfix" id="jsAvatarForm" enctype="multipart/form-data" autocomplete="off" method="post" action="{% url 'users:image_upload' %}" target='frameFile'>
                        <label class="changearea" for="avatarUp">
                            <span id="avatardiv" class="pic">
                                <img width="100" height="100" class="js-img-show" id="avatarShow" src="{{ MEDIA_URL }}{{ request.user.image }}"/>
                            </span>
                            <span class="fl upload-inp-box" style="margin-left:70px;">
                                <span class="button btn-green btn-w100" id="jsAvatarBtn">修改头像</span>
                                <input type="file" name="image" id="avatarUp" class="js-img-up"/>

                        <input type='hidden' name='csrfmiddlewaretoken' value='799Y6iPeEDNSGvrTu3noBrO4MBLv6enY' />
                        {% csrf_token %}
                    </form>

 

11.3.修改密码

 (1)urls

#用户个人中心修改密码
    path("update/pwd/", UpdatePwdView.as_view(),name='update_pwd'),

(2)后台处理

class UpdatePwdView(View):
    """
    个人中心修改用户密码
    """
    def post(self, request):
        modify_form = ModifyPwdForm(request.POST)
        if modify_form.is_valid():
            pwd1 = request.POST.get("password1", "")
            pwd2 = request.POST.get("password2", "")
            if pwd1 != pwd2:
                return HttpResponse('{"status":"fail","msg":"密码不一致"}',  content_type='application/json')
            user = request.user
            user.password = make_password(pwd2)
            user.save()

            return HttpResponse('{"status":"success"}', content_type='application/json')
        else:
            return HttpResponse(json.dumps(modify_form.errors), content_type='application/json')

（3）Ajxa代码放在deco-user.js里面

            async: true,
            success: function(data) {
                if(data.password1){
                    Dml.fun.showValidateError($("#pwd"), data.password1);
                }else if(data.password2){
                    Dml.fun.showValidateError($("#repwd"), data.password2);
                }else if(data.status == "success"){
                    Dml.fun.showTipsDialog({
                        title:'提交成功',
                        h2:'修改密码成功，请重新登录!',
                    });
                    Dml.fun.winReload();
                }else if(data.msg){
                    Dml.fun.showValidateError($("#pwd"), data.msg);
                    Dml.fun.showValidateError($("#repwd"), data.msg);
                }

 base.html

  <header>
        <div class=" header">
            <div class="top">
                <div class="wp">
                    <div class="fl"><p>服务电话：<b>33333333</b></p></div>
                    <!--登录后跳转-->

                    {% if request.user.is_authenticated %}
                        <div class="personal">
                            <dl class="user fr">
                                <dd>{{ user.username }}<img class="down fr"
                                                            src="{% static "images/top_down.png" %}"/></dd>
                                <dt><img width="20" height="20" src="{{ MEDIA_URL }}{{ request.user.image }}"/></dt>
                            </dl>
                            <div class="userdetail">
                                <dl>
                                    <dt><img width="80" height="80" src="{{ MEDIA_URL }}{{ request.user.image }}"/></dt>
                                    <dd>
                                        <h2>{{ request.user.nick_name }}</h2>
                                        <p>{{ request.user.username }}</p>
                                    </dd>
                                </dl>
                                <div class="btn">
                                    <a class="personcenter fl" href="{% url 'users:user_info' %}">进入个人中心</a>
                                    <a class="fr" href="{% url 'logout' %}">退出</a>
                                </div>
                            </div>
                        </div>
                    {% else %}
                        <a style="color:white" class="fr registerbtn" href="{% url 'register' %}">注册</a>
                        <a style="color:white" class="fr loginbtn" href="{% url 'login' %}">登录</a>
                    {% endif %}


                </div>
            </div>

 

同样的把org_base.html和user-center.html也修改一下

            return HttpResponse('{"email":"邮箱已存在"}', content_type='application/json')

        send_register_eamil(email,'update_email')
        return HttpResponse('{"status":"success"}', content_type='application/json')

（4）urils/email_send.py

• 添加一个send_type update_email
• update_email的验证码长度为4

 

(4)Ajax

Ajax代码在dec-user.js里面

    var verify = verifyDialogSubmit(
        [
          {id: '#jsChangeEmail', tips: Dml.Msg.epMail, errorTips: Dml.Msg.erMail, regName: 'email', require: true}
        ]
    );
    if(!verify){
       return;
    }
    $.ajax({
        cache: false,
        type: "get",
        dataType:'json',
        url:"/users/sendemail_code/",
        data:$('#jsChangeEmailForm').serialize(),
        async: true,
        beforeSend:function(XMLHttpRequest){
            $btn.val("发送中...");
            $btn.attr('disabled',true);
        },
        success: function(data){
            if(data.email){
                Dml.fun.showValidateError($('#jsChangeEmail'), data.email);
            }else if(data.status == 'success'){
                Dml.fun.showErrorTips($('#jsChangeEmailTips'), "邮箱验证码已发送");
            }else if(data.status == 'failure'){
                 Dml.fun.showValidateError($('#jsChangeEmail'), "邮箱验证码发送失败");
            }else if(data.status == 'success'){
            }
        },
        complete: function(XMLHttpRequest){
            $btn.val("获取验证码");
            $btn.removeAttr("disabled");
        }
    });

}

加的时候

user_fav.save()
                if int(type) == 1:
                    course = Course.objects.get(id=int(id))
                    course.fav_nums += 1
                    course.save()
                elif int(type) == 2:
                    org = CourseOrg.objects.get(id=int(id))
                    org.fav_nums += 1
                    org.save()
                elif int(type) == 3:
                    teacher = Teacher.objects.get(id=int(id))
                    teacher.fav_nums += 1
                    teacher.save()
