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">

view和前端

# 教师收藏和机构收藏
        has_teacher_faved = False

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

(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,
        })
