1、复制teracher-list.html到templates目录下
2、编辑teacher-list.html，继承base模板
3、编辑organization.views.py
...
from .models import Teacher
class TeacherListView(View):
def get(self, request):
all_teachers = Teacher.objects.all()
return render(request, 'teachers-list.html', {
'all_teachers': all_teachers,
})
4、配置url，编辑organization.urls.py
...
from .views import TeacherListView
urlpatterns = [
...
url(r'teacher/list/$', TeacherListView.as_view(), name='teacher_list' ),
]
5、修改index.html,base.html中的授课教师链接
6、先把所有的讲师都展示出来
分页
编辑organization.views.py
class TeacherListView(View):
def get(self, request):
all_teachers = Teacher.objects.all()
# 分页
try:
page = request.GET.get('page', 1)
except PageNotAnInteger:
page = 1
p = Paginator(all_teachers, 2, request=request)
teachers = p.page(page)
return render(request, 'teachers-list.html', {
'all_teachers': teachers,
})
编辑前端页码
修改前面的展示教师列表
人气排序 和统计教师
编辑organization.views.py
class TeacherListView(View):
def get(self, request):
all_teachers = Teacher.objects.all()
# 人气排序
sort = request.GET.get('sort', '')
if sort:
if sort == 'hot':
all_teachers = all_teachers.order_by('-click_nums')
# 统计教师数
teacher_nums = all_teachers.count()
# 分页
try:
page = request.GET.get('page', 1)
except PageNotAnInteger:
page = 1
p = Paginator(all_teachers, 2, request=request)
teachers = p.page(page)
return render(request, 'teachers-list.html', {
'all_teachers': teachers,
'sort': sort,
'teracher_nums': teacher_nums
})
前端配置
讲师排行榜
编辑organization.views.py
class TeacherListView(View):
def get(self, request):
all_teachers = Teacher.objects.all()
# 人气排序
sort = request.GET.get('sort', '')
if sort:
if sort == 'hot':
all_teachers = all_teachers.order_by('-click_nums')
# 统计教师数
teacher_nums = all_teachers.count()
# 讲师排行榜
rank_teachers = all_teachers.order_by('-click_nums')[:2]
# 分页
try:
page = request.GET.get('page', 1)
except PageNotAnInteger:
page = 1
p = Paginator(all_teachers, 2, request=request)
teachers = p.page(page)
return render(request, 'teachers-list.html', {
'all_teachers': teachers,
'sort': sort,
'teracher_nums': teacher_nums,
'rank_teachers': rank_teachers,
})
前端展示
