学习自慕课网-使用python3.x与Django2.0.1开发的在线教育平台
十、授课教师
10.1.讲师列表页
拷贝teacher-list.html和teacher-detail.html到templates目录下
先改teacher-list.html，同样继承base.html
（1）urls配置
organazition/urls.py
# 讲师列表 re_path('teacher/list/', TeacherListView.as_view(), name="teacher_list"),
(2)给Teacher Model添加一个年龄字段
teacher_age = models.IntegerField('年龄',default=25)
（3）view和模板
# 讲师列表 class TeacherListView(View): def get(self, request): all_teachers = Teacher.objects.all() return render(request,'teachers-list.html',{ 'all_teachers':all_teachers, })
{% for teacher in all_teachers %} <dl class="des"> <dt> <a href="/org/teacher/detail/1/"> <div class="picpic"> <img width="100" height="100" class="scrollLoading" src="{{ MEDIA_URL }}{{ teacher.image }}"/> </div> </a> <div class="btn"> <div class="fr btn2 bdsharebuttonbox" data-text="授课教师-奥巴马-慕学在线" data-desc="我在#慕课网#发现了教师“奥巴马”，对学习中的小伙伴很有帮助，一起来看看吧。" data-comment="奥巴马金牌讲师，从业年限：5年" > <span class="fl">分享</span> <a href="#" class="bds_more" data-cmd="more"></a> </div> </div> </dt> <dd> <a href="/org/teacher/detail/1/"> <h1>{{ teacher.name }}<span class="key picbig">金牌讲师</span></h1> </a> <ul class="cont"> <li>工作年限：<span>{{ teacher.work_years }}年</span></li> <li>工作职位：<span>{{ teacher.work_position }}</span></li> <li>就职公司：<span>{{ teacher.work_company }} </span></li> <li>年龄：<span>{{ teacher.teacher_age }}岁</span></li> <li>教学特点：<span>{{ teacher.points }}</span></li> </ul> </dd> <a class="buy buyservice" href="/org/teacher/detail/1/"><br/>查看<br/>详情</a> </dl> {% endfor %}
10.2.分页
# 讲师列表 class TeacherListView(View): def get(self, request): all_teachers = Teacher.objects.all() # 总共有多少老师使用count进行统计 teacher_nums = all_teachers.count() # 进行分页 try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_teachers, 1, request=request) teachers = p.page(page) return render(request, "teachers-list.html", { "all_teachers": teachers, "teacher_nums": teacher_nums })
<div class="pageturn"> <ul class="pagelist"> {% if all_teachers.has_previous %} <li class="long"><a href="?{{ all_teachers.previous_page_number.querystring }}">上一页</a></li> {% endif %} {% for page in all_teachers.pages %} {% if page %} {% ifequal page all_teachers.number %} <li class="active"><a href="?{{ page.querystring }}">{{ page }}</a></li> {% else %} <li><a href="?{{ page.querystring }}" class="page">{{ page }}</a></li> {% endifequal %} {% else %} <li class="none"><a href="">...</a></li> {% endif %} {% endfor %} {% if all_teachers.has_next %} <li class="long"><a href="?{{ all_teachers.next_page_number.querystring }}">下一页</a></li> {% endif %} </ul> </div>
10.3.排序
# 讲师列表 class TeacherListView(View): def get(self, request): all_teachers = Teacher.objects.all() # 总共有多少老师使用count进行统计 teacher_nums = all_teachers.count() # 人气排序 sort = request.GET.get('sort','') if sort: if sort == 'hot': all_teachers = all_teachers.order_by('-click_nums') #讲师排行榜 sorted_teacher = Teacher.objects.all().order_by('-click_nums')[:3] # 进行分页 try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_teachers, 1, request=request) teachers = p.page(page) return render(request, "teachers-list.html", { "all_teachers": teachers, "teacher_nums": teacher_nums, 'sorted_teacher':sorted_teacher, 'sort':sort, })
排序
<ul class="fl tab_header"> <li {% if sort == '' %}class="active"{% endif %}><a href="?sort=">全部</a> </li> <li {% if sort == 'hot' %}class="active"{% endif %}><a href="?sort=hot">人气 ↓</a></li> </ul>
讲师排行榜
<div class="right layout"> <div class="head">讲师排行榜</div> {% for hot_teacher in sorted_teacher %} <dl class="des"> <span class="num fl">1</span> <a href="/diary/hk_detail/6/"> <dt> <img width="50" height="50" class="scrollLoading" src="{{ MEDIA_URL }}{{ hot_teacher.image }}"/> </dt> </a> <dd> <a href="/diary/hk_detail/6/"> <h1 title="{{ hot_teacher.name }}">{{ hot_teacher.name }}</h1> </a> <p>工作年限：<span>{{ hot_teacher.work_years }}年</span></p> </dd> </dl> {% endfor %} </div>
10.4.讲师详情页展示
# 讲师详情 re_path('teacher/detail/(?P<teacher_id>\d+)/', TeacherDetailView.as_view(), name="teacher_detail"),
#讲师详情 class TeacherDetailView(View): def get(self,request,teacher_id): teacher = Teacher.objects.get(id=int(teacher_id)) all_course = Course.objects.filter(teacher=teacher) # 讲师排行榜 sorted_teacher = Teacher.objects.all().order_by('-click_nums')[:3] return render(request,'teacher-detail.html',{ 'teacher':teacher, 'all_course':all_course, 'sorted_teacher':sorted_teacher, })

10.5.收藏功能
view和前端
# 教师收藏和机构收藏 has_teacher_faved = False if UserFavorite.objects.filter(user=request.user, fav_type=3, fav_id=teacher.id): has_teacher_faved = True has_org_faved = False if UserFavorite.objects.filter(user=request.user, fav_type=2, fav_id=teacher.org.id): has_org_faved = True
{% if has_teacher_faved %}已收藏{% else %}收藏{% endif %} <a class="btn" id="jsRightBtn">{% if has_org_faved %}已收藏{% else %}收藏{% endif %}</a>
teacher-detail.html Ajax代码如下：
{% block custom_js %} <script type="text/javascript"> //收藏分享 function add_fav(current_elem, fav_id, fav_type){ $.ajax({ cache: false, type: "POST", url:"{% url "org:add_fav" %}", data:{'fav_id':fav_id, 'fav_type':fav_type}, async: true, beforeSend:function(xhr, settings){ xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}"); }, success: function(data) { if(data.status == 'fail'){ if(data.msg == '用户未登录'){ window.location.href="/login/"; }else{ alert(data.msg) } }else if(data.status == 'success'){ current_elem.text(data.msg) } }, }); } $('#jsLeftBtn').on('click', function(){ add_fav($(this), {{ teacher.id }}, 3); }); $('#jsRightBtn').on('click', function(){ add_fav($(this), {{ teacher.org.id }}, 2); }); </script> {% endblock %}

10.6.配置全局导航
（1）index.html继承base.html
注意首页有个单独的“index.js”
{% extends 'base.html' %} {% load staticfiles %} {% block title %}课程机构列表{% endblock %} {% block custom_bread %} {% endblock %} {% block content %} <div class="banner"> <div class="wp"> <div

(2)配置全局导航和全局"active"状态
base.html里面设置
<div class="wp"> <ul> <li {% if request.path == '/' %}class="active"{% endif %}><a href="{% url 'index' %}">首页</a></li> <li {% if request.path|slice:'7' == '/course' %}class="active"{% endif %}> <a href="{% url 'course:course_list' %}"> 公开课<img class="hot" src="{% static 'images/nav_hot.png' %}"> </a> </li> <li {% if request.path|slice:'12' == '/org/teacher' %}class="active"{% endif %}> <a href="{% url 'org:teacher_list' %}">授课教师</a> </li > <li {% if request.path|slice:'9' == '/org/list' %}class="active"{% endif %}> <a href="{% url 'org:org_list' %}">授课机构</a></li> </ul> </div>
说明：
- request.path 可以获取当前访问页面的相对url
- 比如“http://127.0.0.1:8000/org/teacher_list/”，则request.path 就是“/org/teacher_list/”
- 比如"http://127.0.0.1:8000/org/teacher/detail/1/"，则request.path 就是“/org/teacher/detail/1/”
- slice:12 是过滤器，取前七位数
- 利用这种发发可以达到全局的“active”效果，而不用每个子页面都要去设置“active”了
10.7.全局搜索功能
通过url中加参数keywords来达到全局搜索的功能
以Course搜索为例：
# 搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # icontains是包含的意思（不区分大小写） # Q可以实现多个字段，之间是or的关系 all_courses = all_courses.filter(Q(name__icontains=search_keywords) | Q(desc__icontains=search_keywords) | Q( detail__icontains=search_keywords))
class CourseListView(View): '''课程列表''' def get(self, request): all_courses = Course.objects.all().order_by('-add_time') # 热门课程推荐 hot_courses = Course.objects.all().order_by('-click_nums')[:3] # 搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # 在name字段进行操作,做like语句的操作。i代表不区分大小写 # or操作使用Q all_courses = all_courses.filter(Q(name__icontains=search_keywords) | Q(desc__icontains=search_keywords) | Q( detail__icontains=search_keywords)) # 排序 sort = request.GET.get('sort', "") if sort: if sort == "students": all_courses = all_courses.order_by("-students") elif sort == "hot": all_courses = all_courses.order_by("-click_nums") # 分页 try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_courses,2 , request=request) courses = p.page(page) return render(request, "course-list.html", { "all_courses":courses, 'sort': sort, 'hot_courses':hot_courses, })
搜索的代码放在deco-common js中：
//顶部搜索栏搜索方法 function search_click(){ var type = $('#jsSelectOption').attr('data-value'), keywords = $('#search_keywords').val(), request_url = ''; if(keywords == ""){ return } if(type == "course"){ request_url = "/course/list?keywords="+keywords }else if(type == "teacher"){ request_url = "/org/teacher/list?keywords="+keywords }else if(type == "org"){ request_url = "/org/list?keywords="+keywords } window.location.href = request_url }
课程机构搜索功能
# 机构搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # 在name字段进行操作,做like语句的操作。i代表不区分大小写 # or操作使用Q all_orgs = all_orgs.filter(Q(name__icontains=search_keywords) | Q(desc__icontains=search_keywords))
class OrgView(View): '''课程机构''' def get(self, request): # 所有课程机构 all_orgs = CourseOrg.objects.all() # 所有城市 all_citys = CityDict.objects.all() # 机构搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # 在name字段进行操作,做like语句的操作。i代表不区分大小写 # or操作使用Q all_orgs = all_orgs.filter(Q(name__icontains=search_keywords) | Q(desc__icontains=search_keywords)) # 城市筛选 city_id = request.GET.get('city','') if city_id: all_orgs = all_orgs.filter(city_id=int(city_id)) # 类别筛选 category = request.GET.get('ct','') if category: all_orgs = all_orgs.filter(category=category) # 热门课程机构排名 hot_orgs = all_orgs.order_by('-click_nums')[:3] # 学习人数和课程数筛选 sort = request.GET.get('sort', "") if sort: if sort == "students": all_orgs = all_orgs.order_by("-students") elif sort == "courses": all_orgs = all_orgs.order_by("-course_nums") # 有多少家机构 org_nums = all_orgs.count() # 对课程机构进行分页 # 尝试获取前台get请求传递过来的page参数 # 如果是不合法的配置参数默认返回第一页 try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 # 这里指从allorg中取五个出来，每页显示5个 p = Paginator(all_orgs, 2, request=request) orgs = p.page(page) return render(request, "org-list.html", { "all_orgs": orgs, "all_citys": all_citys, "org_nums": org_nums, 'city_id':city_id, "category": category, 'hot_orgs':hot_orgs, 'sort':sort, })
授课老师搜索功能
# 搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # 在name字段进行操作,做like语句的操作。i代表不区分大小写 # or操作使用Q all_teachers = all_teachers.filter(name__icontains=search_keywords)
# 讲师列表 class TeacherListView(View): def get(self, request): all_teachers = Teacher.objects.all() # 总共有多少老师使用count进行统计 teacher_nums = all_teachers.count() # 搜索功能 search_keywords = request.GET.get('keywords', '') if search_keywords: # 在name字段进行操作,做like语句的操作。i代表不区分大小写 # or操作使用Q all_teachers = all_teachers.filter(name__icontains=search_keywords) # 人气排序 sort = request.GET.get('sort','') if sort: if sort == 'hot': all_teachers = all_teachers.order_by('-click_nums') #讲师排行榜 sorted_teacher = Teacher.objects.all().order_by('-click_nums')[:3] # 进行分页 try: page = request.GET.get('page', 1) except PageNotAnInteger: page = 1 p = Paginator(all_teachers, 1, request=request) teachers = p.page(page) return render(request, "teachers-list.html", { "all_teachers": teachers, "teacher_nums": teacher_nums, 'sorted_teacher':sorted_teacher, 'sort':sort, })
