代码
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">

{% endblock %}
{% block custom_js %}
<script type="text/javascript" src="{% static 'js/index.js' %}"></script>
{% endblock %}(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,
