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 = 1p = 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 = 1p = 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

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 = Falseif UserFavorite.objects.filter(user=request.user, fav_type=3, fav_id=teacher.id):has_teacher_faved = Truehas_org_faved = Falseif 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”

(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Qall_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 = 1p = 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Qall_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Qall_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Qall_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Qall_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 = 1p = 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,})
