课程讲师列表页

- (1)定义 TeacherListView 类视图,处理课程讲师列表页
# apps/organization/views.py
class TeacherListView(View):
"""
课程讲师列表页类视图
"""
def get(self, request):
current_page_name = "teacher_list_page"
all_teachers = Teacher.objects.all().order_by("-add_time")
# 根据人气(点击量)对 all_teachers 进行排序
sort = request.GET.get("sort", "")
if sort:
if sort == "hot":
all_teachers = all_teachers.order_by("-click_nums")
# 获取人气排行前3的讲师
sorted_teachers = all_teachers.order_by("-click_nums")[:3]
# 对课程讲师进行分页
try:
page = request.GET.get('page', 1)
except PageNotAnInteger:
page = 1
# Paginator 接收 3 个参数, 需要分页的对象列表, 每页显示的对象数量, 以及 request
p = Paginator(all_teachers, 2, request=request)
teachers = p.page(page)
context = {
"all_teachers": teachers,
"sorted_teachers": sorted_teachers,
"sort": sort,
"current_page_name": current_page_name,
}
return render(request, "teachers-list.html", context)
- (2)配置 url
# apps/organization/urls.py
from django.urls import path, re_path
from .views import TeacherListView
app_name = "org"
urlpatterns = [
...
# 课程讲师列表页
path("teacher/list/", TeacherListView.as_view(), name="teacher_list"),
]
- (3)前端 teacher-list.html 页面
# templates/teacher-list.html

二、课程讲师详情页
003.png
- (1)定义 TeacherDetailView 类视图
# apps/organization/views.py
class TeacherDetailView(View):
def get(self, request, id):
current_page_name = "teacher_list_page"
teacher = Teacher.objects.get(pk=id)
# 获取人气排行前3的讲师
sorted_teachers = Teacher.objects.all().order_by("-click_nums")[:3]
# 获取讲师所有课程
teacher_courses = Course.objects.filter(teacher=teacher)
# 判断用户是否已收藏过这个讲师
has_teacher_favorite = False
if UserFavorite.objects.filter(user=request.user, favorite_type=3, favorite_id=teacher.id):
has_teacher_favorite = True
# 判断用户是否已收藏过这个讲师所在机构
has_organization_favorite = False
if UserFavorite.objects.filter(user=request.user, favorite_type=2, favorite_id=teacher.organization.id):
has_organization_favorite = True
context = {
"teacher": teacher,
"sorted_teachers": sorted_teachers,
"teacher_courses": teacher_courses,
"has_teacher_favorite": has_teacher_favorite,
"has_organization_favorite": has_organization_favorite,
"current_page_name": current_page_name,
}
return render(request, "teacher-detail.html", context)
- (2)配置 url
# apps/organization/urls.py
from django.urls import path, re_path
from .views import TeacherDetailView
app_name = "org"
urlpatterns = [
...
# 课程讲师详情页
path("teacher/detail/<int:id>", TeacherDetailView.as_view(), name="teacher_detail"),
]
- (3)前端页面 teacher-detail.html
课程讲师详情页有两个收藏按钮,分别是左侧的收藏讲师和右侧的收藏结构,这两个收藏是通过 ajax 实现的,同第7章的课程机构收藏功能是完全相同的,直接拷贝原有的代码即可.
详情页的讲师排行榜也是和列表页讲师排行榜是相同的,代码一致.
