接着上期代码框架，开发第6个功能，用户管理，查看用户信息和学生用户属性值，尤其是总积分值，还可以查看积分流水明细，完成任务奖励积分，兑换物品消耗积分。

第一步：编写第6个功能-用户管理

1，编辑模型文件：

./mysite/study_system/models.py:

无新增模型

2，编辑urls配置文件：
./mysite/study_system/urls.py

# 用户管理url
path('user/getUserInfo/', views.getUserInfo, name='getUserInfo'),
path('user/toModUserInfo/', views.toModUserInfo, name='toModUserInfo'),
path('user/updateUserInfo/', views.updateUserInfo, name='updateUserInfo'),
# 积分流水url
path('item/getStudyPointsList/', views.getStudyPointsList, name='getStudyPointsList'),

3，编辑视图文件：
./mysite/study_system/views.py

def getUserInfo(request):'''@方法名称: 用户管理视图@作    者: PandaCode辉@weixin公众号: PandaCode辉@创建时间: 2023-10-10'''# 响应容器rsp_dict = {}# 获取当前用户名username = request.session.get('username')# 根据用户名获取用户对象cur_user = StudyUser.objects.get(username=username)print('根据用户名查询用户对象:' + str(cur_user))try:# 学生用户总积分值，需要取学生用户，关联的属性表的值cur_user_attr = StudyUserAttribute.objects.get(user_id=cur_user)rsp_dict['cur_user_attr'] = cur_user_attrexcept Exception as e:print('根据用户名查询属性表，查无记录.')template_name = "study_system/home.html"rsp_dict["pageTitle"] = "用户信息"rsp_dict['html_file'] = 'study_system/user/userInfo.html'rsp_dict['cur_user'] = cur_userreturn render(request, template_name, rsp_dict)def toModUserInfo(request):'''@方法名称: 跳转到修改用户视图@作    者: PandaCode辉@weixin公众号: PandaCode辉@创建时间: 2023-10-10'''# 响应容器rsp_dict = {}rest = request.GETuser_id = rest['userId']# 根据用户名获取用户对象cur_user = StudyUser.objects.get(user_id=user_id)print('查询用户对象:' + str(cur_user))try:# 学生用户总积分值，需要取学生用户，关联的属性表的值cur_user_attr = StudyUserAttribute.objects.get(user_id=cur_user)rsp_dict['cur_user_attr'] = cur_user_attrexcept Exception as e:print('根据用户名查询属性表，查无记录.')rsp_dict["pageTitle"] = "修改用户"rsp_dict['html_file'] = 'study_system/user/updateUserInfo.html'rsp_dict['cur_user'] = cur_userreturn render(request, "study_system/home.html", rsp_dict)def updateUserInfo(request):'''@方法名称: ajax请求, 表单视图，更新用户信息@作    者: PandaCode辉@weixin公众号: PandaCode辉@创建时间: 2023-10-10'''# 初始化响应容器rsp_dict = {"result": "error", "errorMsg": "系统错误"}# 是否ajax请求if request.is_ajax():try:rest = request.POST# 用户值user_id = int(rest['userId'])username = rest['userName']password = rest['password']email = rest['email']phone_num = rest['phoneNum']role = int(rest['role'])# 根据ID查询对象数据, filter 返回的是列表对象，一个对象取list.0studyUser = StudyUser.objects.filter(user_id=user_id)# 今天# UTC格式当前时区时间t = time.localtime()work_date = time.strftime("%Y-%m-%d %H:%M:%S", t)print('当前日期时间:' + str(work_date))# 保存到数据库是否成功，更新用户表studyUser.update(username=username, password=password,email=email, phone_num=phone_num, update_time=work_date)print('更新用户表成功.')# 属性值study_level = int(rest['studyLevel'])#  用户属性值，学习级别，不为空，则更新属性值if study_level != "":# 属性值study_level = int(rest['studyLevel'])intelligence = int(rest['intelligence'])memory = int(rest['memory'])diligence = int(rest['diligence'])physical_fitness = int(rest['physicalFitness'])other_subjects = rest['otherSubjects']notes = rest['notes']# 根据用户名获取用户对象cur_user = StudyUser.objects.get(user_id=user_id)# print('查询用户对象:' + str(cur_user))# 学生用户总积分值，需要取学生用户，关联的属性表的值studyUserAttribute = StudyUserAttribute.objects.filter(user_id=cur_user)# 保存到数据库是否成功，更新用户属性表studyUserAttribute.update(study_level=study_level, intelligence=intelligence,memory=memory, diligence=diligence,physical_fitness=physical_fitness,other_subjects=other_subjects, notes=notes,update_time=work_date)print('更新用户属性表成功.')rsp_dict["result"] = "success"except Exception as e:rsp_dict["errorMsg"] = "更新用户信息,保存到数据库失败."# 成功与否都返回json数据格式return JsonResponse(rsp_dict)def getStudyPointsList(request):'''@方法名称: 获取积分明细列表@作    者: PandaCode辉@weixin公众号: PandaCode辉@创建时间: 2023-10-10'''# 响应容器rsp_dict = {}# 获取当前用户名username = request.session.get('username')# 根据用户名获取用户对象cur_user = StudyUser.objects.get(username=username)print('根据用户名查询用户对象:' + str(cur_user))#查询积分列表data_list = StudyPoint.objects.filter(user_id=cur_user).order_by('-created_time')rsp_dict['data_list'] = data_listcontext_object_name = "study_points_list"template_name = "study_system/home.html"rsp_dict['html_file'] = 'study_system/item/studyPointsList.html'rsp_dict['context_object_name'] = context_object_namereturn render(request, template_name, rsp_dict)

4，编辑页面模板代码：

4.1. 用户管理页面
./mysite/study_system/templates/study_system/user/userInfo.html

<!-- 结果显示区 -->
<div id="dataList">{% if cur_user %}<ul class="dataCardList"><li>【用户ID ：{{ cur_user.user_id }}】</li><li>【用户名 ：{{ cur_user.username }}】</li><li>【邮箱 ： {{ cur_user.email }}】</li><li>【手机号码 ： {{ cur_user.phone_num }}】</li>{% if cur_user.role == 1 %}<li>【角色 ：系统管理员 】</li>{% elif cur_user.role == 2 %}<li>【角色 ：辅导员 】</li>{% elif cur_user.role == 3 %}<li>【角色 ：学生 】</li>{% elif cur_user.role == 4 %}<li>【角色 ：自导自学 】</li>{% endif %}{#             学生用户属性值#}{% if cur_user_attr %}{% if cur_user_attr.study_level == 1 %}<li>【级别 ：Lv1-小学 】</li>{% elif cur_user_attr.study_level == 2 %}<li>【级别 ：Lv2-初中 】</li>{% elif cur_user_attr.study_level == 3 %}<li>【级别 ：Lv3-高中 】</li>{% elif cur_user_attr.study_level == 4 %}<li>【级别 ：Lv4-本科 】</li>{% elif cur_user_attr.study_level == 5 %}<li>【级别 ：Lv5-硕士 】</li>{% elif cur_user_attr.study_level == 6 %}<li>【级别 ：Lv6-博士 】</li>{% elif cur_user_attr.study_level == 7 %}<li>【级别 ：Lv7-博士后 】</li>{% endif %}<li>【智力 ：{{ cur_user_attr.intelligence }} 点】</li><li>【记忆力 ：{{ cur_user_attr.memory }} 点】</li><li>【勤奋力 ：{{ cur_user_attr.diligence }} 点】</li><li>【体能 ：{{ cur_user_attr.physical_fitness }} 点】</li><li class="strongTab"><span>【总积分 ：{{ cur_user_attr.total_points }} 点】<a href="/study_system/item/getStudyPointsList/">积分明细</a></span></li><li>【学科属性 ：{{ cur_user_attr.other_subjects }}】</li><li class="strongTab">【备注提醒 ：{{ cur_user_attr.notes }}】</li>{% endif %}<li>【更新时间 ：{{ cur_user.update_time| date:'Y-m-d H:i:s' }}】</li><li><a href="/study_system/user/toModUserInfo?userId={{ cur_user.user_id }}"class="btn btn-default btn-lg btn-block btn-a">修改用户信息</a></li></ul>{% else %}<strong>查无记录</strong>{% endif %}
</div>

4.2. 修改用户信息页面
./mysite/study_system/templates/study_system/user/updateUserInfo.html

<script type="text/javascript">function updateUserInfo() {var userId = $("input[name='userId']").val();var userName = $("input[name='userName']").val();var password = $("input[name='password']").val();var email = $("input[name='email']").val();var phoneNum = $("input[name='phoneNum']").val();var role = $("select[name='role']").val();var studyLevel = "";var intelligence = "";var memory = "";var diligence = "";var physicalFitness = "";var otherSubjects = "";var notes = "";var cur_user_attr = '{{ cur_user_attr }}';// 用户属性不为空时if (cur_user_attr) {studyLevel = $("select[name='studyLevel']").val();intelligence = $("input[name='intelligence']").val();memory = $("input[name='memory']").val();diligence = $("input[name='diligence']").val();physicalFitness = $("input[name='physicalFitness']").val();otherSubjects = $("textarea[name='otherSubjects']").val();notes = $("textarea[name='notes']").val();}var csrf_token = '{{ csrf_token }}';$.post("/study_system/user/updateUserInfo/",{'userId': userId,'userName': userName,'password': password,'email': email,'phoneNum': phoneNum,'role': role,'studyLevel': studyLevel,'intelligence': intelligence,'memory': memory,'diligence': diligence,'physicalFitness': physicalFitness,'otherSubjects': otherSubjects,'notes': notes,// 将token值放到请求数据部分,token的键必须是 csrfmiddlewaretoken'csrfmiddlewaretoken': csrf_token,}, function (data) {if ("success" == data.result) {alert("更新成功");window.location.href = "/study_system/user/getUserInfo/";} else {alert("更新失败:" + data.errorMsg);}});}

第二步：运行测试-用户管理功能

1，登录用户后，点击查看用户信息页面

2，点击查看积分明细页面

3，点击修改用户页面
