9-1 讲师列表页

teacherlist 和 teacher detail 一起放到template目录之下

继承base页面

书写view与配置url

    # 讲师列表path('teacher_list/', TeacherListView.as_view(), name="teacher_list"),

添加讲师的年龄字段

    age = models.IntegerField(default=18, verbose_name=u"年龄")

分页仿照orglist 注意object_list

view

# 课程讲师列表页
class TeacherListView(View):def get(self, request):all_teacher = Teacher.objects.all()# 总共有多少老师使用count进行统计teacher_nums = all_teacher.count()# 对讲师进行分页# 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_teacher, 4, request=request)teachers = p.page(page)return render(request, "teachers-list.html", {"all_teacher":teachers,"teacher_nums":teacher_nums})

排序 & 讲师排行榜

 sort = request.GET.get("sort", "")if sort:if sort == "hot":all_teacher = all_teacher.order_by("-click_nums")

 "sort":sort

将sort return到前端。实现active

排行榜讲师

            # 排行榜讲师rank_teacher = Teacher.objects.all().order_by("-fav_nums")[:5]

forloop.count 取出当前是第几次循环

9-2 讲师详情页

配置url和view

列表页中配置入口

# 教师详情页面class TeacherDetailView(View):def get(self, request, teacher_id):teacher = Teacher.objects.get(id = int(teacher_id))all_course = teacher.course_set.all()# 排行榜讲师rank_teacher = Teacher.objects.all().order_by("-fav_nums")[:5]has_fav_teacher = Falseif UserFavorite.objects.filter(user=request.user, fav_type=3, fav_id= teacher.id):has_fav_teacher = Truehas_fav_org = Falseif  UserFavorite.objects.filter(user=request.user, fav_type=2, fav_id= teacher.org.id):has_fav_org = Truereturn render(request, "teacher-detail.html", {"teacher":teacher,"all_course":all_course,"rank_teacher":rank_teacher,"has_fav_teacher":has_fav_teacher,"has_fav_org":has_fav_org,})

    # 访问机构讲师re_path('teacher/detail/(?P<teacher_id>\d+)/', TeacherDetailView.as_view(), name="teacher_detail"),
