学习自慕课网-使用python3.x与Django2.0.1开发的在线教育平台

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">

                    <dt>

                        <a href="/org/teacher/detail/1/">

(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,

        })

course/views.py

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))

        all_citys = CityDict.objects.all()

        # 机构搜索功能

        search_keywords = request.GET.get('keywords', '')

        if search_keywords:

            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))

                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:

        except PageNotAnInteger:

        p = Paginator(all_orgs, 2, request=request)

        orgs = p.page(page)

        return render(request, "org-list.html", {
