十五、首页全局配置
1、首页前端页面配置
将index.html继承base.html页面，修改继承的block地方：
修改base.html页面中导航栏选中状态的代码：
2、全局搜索功能
首页的全局搜索功能可以对课程，机构，教师进行全局搜索，搜索的代码放在deco-common.js文件中：
1 //顶部搜索栏搜索方法 2 function search_click(){ 3 var type = $('#jsSelectOption').attr('data-value'), 4 keywords = $('#search_keywords').val(), 5 request_url = ''; 6 if(keywords == ""){ 7 return 8 } 9 if(type == "course"){ 10 request_url = "/course/list?keywords="+keywords 11 }else if(type == "teacher"){ 12 request_url = "/org/teacher/list?keywords="+keywords 13 }else if(type == "org"){ 14 request_url = "/org/list?keywords="+keywords 15 } 16 window.location.href = request_url 17 }
只需要在课程列表接口、机构列表接口、讲师列表接口中加入搜索的逻辑即可：
1 class CourseListView(View): 2 """课程列表页""" 3 def get(self, request): 4 # 获取所有的课程 5 all_courses = Course.objects.all() 6 7 # 排序（学习人数，点击数） 8 sort = request.GET.get('sort', '') 9 if sort: 10 if sort == 'students': 11 all_courses = all_courses.order_by('-students') 12 elif sort == 'hot': 13 all_courses = all_courses.order_by('-click_nums') 14 15 # 热门课程 16 hot_courses = all_courses.order_by('-click_nums')[:2] 17 18 # 搜索 19 search_keywords = request.GET.get('keywords', '') 20 if search_keywords: 21 all_courses = all_courses.filter(Q(name__icontains=search_keywords)| 22 Q(desc__icontains=search_keywords)| 23 Q(detail__icontains=search_keywords)) 24 25 # 分页 26 try: 27 page = request.GET.get('page', 1) 28 except PageNotAnInteger: 29 page = 1 30 p = Paginator(all_courses, 3, request=request) 31 courses = p.page(page) 32 33 return render(request, 'course-list.html', { 34 'all_courses': courses, 35 'sort': sort, 36 'hot_courses': hot_courses 37 })
1 class OrgView(View): 2 """机构列表""" 3 def get(self, request): 4 # 取出所有的机构 5 all_orgs = CourseOrg.objects.all() 6 7 # 取出所有的城市 8 all_citys = CityDict.objects.all() 9 10 # 搜索 11 search_keywords = request.GET.get('keywords', '') 12 if search_keywords: 13 all_orgs = all_orgs.filter(Q(name__icontains=search_keywords)| 14 Q(desc__icontains=search_keywords)) 15 16 # 排名筛选(根据点击量排名) 17 hot_orgs = all_orgs.order_by('-click_nums')[:3] 18 19 # 学习人数和课程数排名筛选 20 sort = request.GET.get('sort', '') 21 if sort: 22 if sort == 'students': 23 all_orgs = all_orgs.order_by('-students') 24 elif sort == 'courses': 25 all_orgs = all_orgs.order_by('-course_nums') 26 27 # 城市筛选(从request中获取城市的id) 28 city_id = request.GET.get('city', '') 29 if city_id: 30 all_orgs = all_orgs.filter(city_id=int(city_id)) 31 32 # 类别筛选(从request中获取机构类别ct) 33 category = request.GET.get('ct', '') 34 if category: 35 all_orgs = all_orgs.filter(category=category) 36 37 # 筛选完再统计数量 38 org_nums = all_orgs.count() 39 40 # 分页 41 try: 42 page = request.GET.get('page', 1) 43 except PageNotAnInteger: 44 page = 1 45 p = Paginator(all_orgs, 5, request=request) 46 orgs = p.page(page) 47 48 return render(request, 'org-list.html', { 49 'all_orgs': orgs, 50 'all_citys': all_citys, 51 'org_nums': org_nums, 52 'city_id': city_id, 53 'category': category, 54 'hot_orgs': hot_orgs, 55 'sort': sort 56 })
1 class TeacherListView(View): 2 """讲师列表页面""" 3 def get(self, request): 4 # 获取所有的讲师 5 all_teachers = Teacher.objects.all() 6 7 # 搜索 8 search_keywords = request.GET.get('keywords', '') 9 if search_keywords: 10 all_teachers = all_teachers.filter(name__icontains=search_keywords) 11 12 # 统计讲师的总数 13 teacher_nums = all_teachers.count() 14 15 # 排序,按点击数排序 16 sort = request.GET.get('sort', '') 17 if sort: 18 if sort == 'hot': 19 all_teachers = all_teachers.order_by('-click_nums') 20 21 # 讲师排行版 22 teacher_sorted = all_teachers.order_by('-click_nums')[:3] 23 24 # 分页 25 try: 26 page = request.GET.get('page', 1) 27 except PageNotAnInteger: 28 page = 1 29 p = Paginator(all_teachers, 5, request=request) 30 teachers = p.page(page) 31 32 return render(request, 'teachers-list.html', { 33 'all_teachers': teachers, 34 'teacher_nums': teacher_nums, 35 'sort': sort, 36 'teacher_sorted': teacher_sorted 37 })
十六、个人中心
1、个人中心页面
1.1 个人中心前端页面配置
在templates目录下新建usercenter-base.html文件，作为个人中心页面的母版，然后将usercenter-info.html页面拷贝到该目录下，并把其中的内容拷贝到母版中，修改其中需要block的地方：
1 {% load staticfiles %} 2 3 <!DOCTYPE html> 4 <html> 5 6 <head> 7 <meta charset="UTF-8"> 8 <meta name="renderer" content="webkit"> 9 <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1" > 10

</script> 385 </body> 386 </html>
然后将usercenter-info.html页面继承母版：
1.2 个人信息接口
在users/views.py中编写个人中心的接口：
1 class UserInfoView(View): 2 """个人中心页面""" 3 def get(self, request): 4 return render(request, 'usercenter-info.html', { 5 6 })
先在users下新建urls.py文件，然后在MxOnline/urls.py中配置个人信息的路由分发：
1 urlpatterns = [ 2 path('users/', include('users.urls', namespace='users')), # 个人信息 3 ]
在users/urls.py中配置个人中心页面的url：
1 from django.urls import path 2 3 from .views import UserInfoView 4 5 6 app_name = 'users' 7 8 urlpatterns = [ 9 path('info/', UserInfoView.as_view(), name='user_info'), # 个人中心 10 ]
修改个人中心页面中显示个人信息的代码：
要完善个人信息接口，首先需要在form.py中加入个人信息的form表单验证：
1 class UserInfoForm(forms.ModelForm): 2 """个人信息表单验证""" 3 class Meta: 4 model = UserProfile 5 fields = ['nick_name', 'gender', 'birthday', 'address', 'mobile']
然后完善个人信息接口中更新个人信息的逻辑：
1 class UserInfoView(View): 2 """个人中心页面""" 3 def get(self, request): 4 return render(request, 'usercenter-info.html') 5 6 def post(self, request): 7 userinfo_form = UserInfoForm(request.POST, instance=request.user) 8 if userinfo_form.is_valid(): 9 userinfo_form.save() 10 return HttpResponse('{"status": "success"}', content_type='application/json') 11 else: 12 return HttpResponse(json.dumps(userinfo_form.errors), content_type='application/json')
然后修改个人中心页面中显示个人信息的代码，加上{% csrf_token %}：
1.3 修改用户头像接口
首先在form.py文件中加入头像的ModelForm表单验证：
1 class UploadImageForm(forms.ModelForm): 2 """修改用户头像""" 3 class Meta: 4 model = UserProfile 5 fields = ['image']
然后完成修改用户头像的接口：
1 class UploadImageView(LoginRequiredMixin, View): 2 """用户头像修改""" 3 def post(self, request): 4 # 上传的文件都在request.FILES里面获取 5 image_form = UploadImageForm(request.POST, request.FILES) 6 if image_form.is_valid(): 7 # 将获取到的图片保存到数据库 8 image = image_form.cleaned_data['image'] 9 request.user.image = image 10 request.user.save() 11 12 return HttpResponse('{"status": "success"}', content_type='application/json') 13 else: 14 return HttpResponse('{"status": "fail"}', content_type='application/json')
配置url：
1 from .views import UploadImageView 2 3 4 urlpatterns = [ 5 path('image/upload', UploadImageView.as_view(), name='image_upload'), # 修改头像 6 ]
修改个人中心页面显示用户头像的代码：
1.4 修改密码接口
1 class UpdatePwdView(LoginRequiredMixin, View): 2 """修改密码""" 3 def post(self, request): 4 modify_form = ModifyPwdForm(request.POST) 5 if modify_form.is_valid(): 6 # 从request中获取密码 7 pwd1 = request.POST.get('password1', '') 8 pwd2 = request.POST.get('password2', '') 9 if pwd1 != pwd2: 10 return HttpResponse('{"status": "fail", "mag": "密码不一致"}', content_type='application/json') 11 12 # 保存密码 13 user = request.user 14 user.password = make_password(pwd2) 15 user.save() 16 17 return HttpResponse('{"status": "success"}', content_type='application/json') 18 else: 19 return HttpResponse(json.dumps(modify_form.errors), content_type='application/json')
配置url：
1 from .views import UpdatePwdView 2 3 urlpatterns = [ 4 path('update/pwd/', UpdatePwdView.as_view(), name='update_pwd'), # 修改密码 5 ]
修改密码的ajax代码在deco-user.js文件中，现在只需要在usercenter-base.html页面中修改密码的form表单中加上{% csrf_token %}：
修改完成之后需要重新登录，现在修改右上角的登录状态以及显示信息，在usercenter-base.html页面中：
同时将base.html页面和org_base.html页面也修改了。
1.5 发送邮箱验证码接口
首先在邮箱验证码的model中添加SEND_CHOICES的选项，并将发送类型字段的长度改成30：
1 class EmailVerifyRecord(models.Model): 2 """邮箱验证码""" 3 SEND_CHOICES = ( 4 ('register', '注册'), 5 ('forget', '找回密码'), 6 ('update_email', '修改邮箱') 7 ) 8 9 code = models.CharField('验证码', max_length=20) 10 email = models.EmailField('邮箱', max_length=50) 11 send_type = models.CharField('发送类型', max_length=30, choices=SEND_CHOICES) 12 send_time = models.DateTimeField('发送时间', default=datetime.now) 13 14 class Meta: 15 verbose_name = '邮箱验证码' 16 verbose_name_plural = verbose_name
迁移数据库。
1 class SendEmailCodeView(LoginRequiredMixin, View): 2 """发送邮箱验证码""" 3 def get(self, request): 4 # 从request中获取email 5 email = request.GET.get('email', '') 6 7 # 判断邮箱是否已经存在 8 if UserProfile.objects.filter(email=email): 9 return HttpResponse('{"email": "邮箱已存在"}', content_type='application/json') 10 11 # 发送邮件 12 send_register_email(email, 'update_email') 13 return HttpResponse('{"status": "success"}', content_type='application/json')
配置url：
from .views import SendEmailCodeView urlpatterns = [ path("sendemail_code/", SendEmailCodeView.as_view(),name='sendemail_code'), # 发送邮箱验证码 ]
发送邮件的ajax代码在dec-user.js中，在utils/email_send.py中增加发送邮件的内容:
1 if send_type == 'update_email': 2 email_title = "知能网邮箱修改验证码" 3 email_body = "你的邮箱验证码为{0}".format(code) 4 5 send_status = send_mail(email_title, email_body, EMAIL_FROM, [email]) 6 if send_status: 7 pass
1.6 修改邮箱接口
1 class UpdateEmailView(LoginRequiredMixin, View): 2 """修改邮箱""" 3 def post(self, request): 4 # 从request中获取email和code 5 email = request.POST.get('email', '') 6 code = request.POST.get('code', '') 7 8 # 在数据库中查找是否已有记录 9 existed_records = EmailVerifyRecord.objects.filter(email=email, code=code, send_type='update_email') 10 if existed_records: 11 # 修改邮箱 12 user = request.user 13 user.email = email 14 user.save() 15 16 return HttpResponse('{"status": "success"}', content_type='application/json') 17 else: 18 return HttpResponse('{"email": "验证码无效"}', content_type='application/json')
配置url：
1 from .views import UpdateEmailView 2 3 urlpatterns = [ 4 path("update_email/", UpdateEmailView.as_view(), name='update_email'), # 修改邮箱 5 ]
修改邮箱的ajax代码在dec-user.js中，然后在usercenter-base.html中显示修改邮箱代码加上{% csrf_token %}：
2、我的课程页面
2.1 前端页面配置
将前端页面usercenter-mycourse.html拷贝到templates下。
然后继承usercenter-base.html页面，重写需要block的地方：
2.2 我的课程接口
1 class MyCourseView(LoginRequiredMixin, View): 2 """我的课程页面""" 3 def get(self, request): 4 # 获取用户的课程 5 user_courses = UserCourse.objects.filter(user=request.user) 6 7 return render(request, 'usercenter-mycourse.html', { 8 'user_courses': user_courses 9 })
配置url：
1 urlpatterns = [ 2 path('mycourse/', MyCourseView.as_view(), name='mycourse'), # 我的课程 3 ]
然后修改usercenter.html页面中跳转到我的课程页面的url：
修改我的课程页面中显示我的课程的代码：
3、我的收藏页面
3.1 课程机构页面
前端页面配置，先将usercenter-fav-org.html页面拷贝到templates下，继承usercenter-base.html页面，重写需要block的地方：

配置url：
1 urlpatterns = [ 2 path('myfav/org/', MyFavOrgView.as_view(), name="myfav_org"), # 我的收藏 - 机构 3 ]
修改usercenter-base.html页面中跳转到我的收藏的url：
修改我的收藏页面显示收藏机构的代码：
3.2 授课教师页面
前端页面配置，先将usercenter-fav-teacher.html页面拷贝到templates下，继承usercenter-base.html页面，重写需要block的地方：
我的收藏 - 教师接口编写：
1 class MyFavTeacherView(LoginRequiredMixin, View): 2 """我的收藏 - 教师""" 3 def get(self, request): 4 teacher_list = [] 5 fav_teachers = UserFavorite.objects.filter(user=request.user, fav_type=3) 6 for fav_teacher in fav_teachers: 7 teacher_id = fav_teacher.fav_id 8 teacher = Teacher.objects.get(id=teacher_id) 9 teacher_list.append(teacher) 10 11 return render(request, 'usercenter-fav-teacher.html', { 12 'teacher_list': teacher_list 13 })
配置url：
1 urlpatterns = [ 2 path('myfav/teacher/', MyFavTeacherView.as_view(), name="myfav_teacher"), # 我的收藏 - 教师 3 ]
该页面需要显示教师课程的数量，需要在teacher的model中添加获取课程数量的函数：
1 class Teacher(models.Model): 2 """机构老师""" 3 org = models.ForeignKey(CourseOrg, verbose_name='所属机构', on_delete=models.CASCADE) 4 name = models.CharField('老师名', max_length=50) 5 age = models.IntegerField('年龄', default=25) 6 work_years =models.IntegerField('工作年限', default=0) 7 work_company = models.CharField('就职公司', max_length=50) 8 work_position = models.CharField('工作职位', max_length=50) 9 points = models.CharField('教学特点', max_length=50) 10 click_nums = models.IntegerField('点击数', default=0) 11 fav_nums = models.IntegerField('收藏数', default=0) 12 image = models.ImageField('头像', upload_to='teacher/%Y/%m', max_length=100, default='') 13 add_time = models.DateTimeField('添加时间', default=datetime.now) 14 15 class Meta: 16 verbose_name = '教师' 17 verbose_name_plural = verbose_name 18 19 # 获取教师课程的数量 20 def get_course_nums(self): 21 return self.course_set.all().count() 22 23 def __str__(self): 24 return '[{}]机构的教师:{}'.format(self.org.name, self.name)

在MxOnline/urls.py中配置url：
1 urlpatterns = [ 2 path('logout/', LogoutView.as_view(), name='logout'), # 登出 3 ]
然后在三个base页面修改登出的url。
6、点击数、收藏数
在用户点击开始学习之后，学习人数需要加1，在课程章节接口CourseLessonView中完善加1操作：
1 class CourseLessonView(LoginRequiredMixin, View): 2 """课程章节""" 3 def get(self, request, course_id): 4 # 根据前端传递的课程id找到对应的课程 5 course = Course.objects.get(id=int(course_id)) 6 7 # 学习人数+1 8 course.students += 1 9 course.save() 10 11 # 课程和用户关联，先判断用户是否已经学习过该课程 12 user_courses = UserCourse.objects.filter(user=request.user, course=course) 13 if not user_courses: 14 # 没有学习过该课程，关联 15 user_course = UserCourse(user=request.user, course=course) 16 user_course.save() 17 18 # 获取所有的资源文件 19 all_resources = CourseResourse.objects.filter(course=course) 20 21 # 相关课程推荐 22 # 找到学习这门课程的所有用户 23 user_courses = UserCourse.objects.filter(course=course) 24 # 找到学习这门课的所有用户的id 25 user_ids = [user_course.user_id for user_course in user_courses] 26 # 通过所有用户的id，找到所有用户学习过的所有课程 27 all_user_courses = UserCourse.objects.filter(user_id__in=user_ids) 28 # 取出所有课程id 29 course_ids = [all_user_course.course_id for all_user_course in all_user_courses] 30 # 通过所有课程id找到所有的课程，按点击量区5个 31 relate_courses = Course.objects.filter(id__in=course_ids).order_by('-click_nums')[:5] 32 33 return render(request, 'course-video.html', { 34 'course': course, 35 'all_resources': all_resources, 36 'relate_courses': relate_courses 37 })
在点击教师进入教师详情页面，教师的点击数加1，在教师详情接口TeacherDetailView中完善加1逻辑：
1 class TeacherDetailView(View): 2 """讲师详情页面""" 3 def get(self, request, teacher_id): 4 # 根据前端的讲师id找到对应的讲师 5 teacher = Teacher.objects.get(id=int(teacher_id)) 6 7 # 老师点击数加1 8 teacher.click_nums += 1 9 teacher.save() 10 11 # 获取该老师所有的课程 12 all_courses = Course.objects.filter(teacher=teacher) 13 14 # 讲师排行 15 teacher_sorted = Teacher.objects.all().order_by('-click_nums')[:3] 16 17 # 讲师收藏、机构收藏 18 has_teahcer_faved = False 19 if UserFavorite.objects.filter(user=request.user, fav_type=3, fav_id=teacher_id): 20 has_teahcer_faved = True 21 has_org_faved = False 22 if UserFavorite.objects.filter(user=request.user, fav_type=2, fav_id=teacher.org.id): 23 has_org_faved = True 24 25 return render(request, 'teacher-detail.html', { 26 'teacher': teacher, 27 'all_courses': all_courses, 28 'teacher_sorted': teacher_sorted, 29 'has_teahcer_faved': has_teahcer_faved, 30 'has_org_faved': has_org_faved 31 })
在点击机构进入机构详情页，机构的点击数加1，在机构详情接口OrgHomeView中完善点击数加1逻辑：
1 class OrgHomeView(View): 2 """机构首页页面""" 3 def get(self, request, org_id): 4 # 根据前端的id找机构 5 org = CourseOrg.objects.get(id=int(org_id)) 6 7 # 点击数加1 8 org.click_nums += 1 9 org.save() 10 11 # 反向查询机构所有的课程和教师 12 all_courses = org.course_set.all() 13 all_teachers =org.teacher_set.all() 14 15 # 标记 16 current_page = 'home' 17 18 # 判断收藏状态 19 has_fav = False 20 if request.user.is_authenticated: 21 if UserFavorite.objects.filter(user=request.user, fav_id=org.id, fav_type=2): 22 has_fav = True 23 24 return render(request, 'org-detail-homepage.html', { 25 'org': org, 26 'all_courses': all_courses, 27 'all_teachers': all_teachers, 28 'current_page': current_page, 29 'has_fav': has_fav 30 })
用户在进行收藏和取消收藏时都需要对收藏数进行加和减的操作，在机构收藏接口OrgFavView中完善收藏数的逻辑：
1 class OrgFavView(View): 2 """机构收藏""" 3 def post(self, request): 4 # 从request中获取收藏的机构id和类型 5 id = request.POST.get('fav_id', 0) 6 type = request.POST.get('fav_type', 0) 7 8 # 未登录返回json数据到前端，由前端进行登录页面的跳转 9 if not request.user.is_authenticated: 10 return HttpResponse('{"status": "fail", "msg": "用户未登录"}', content_type='application/json') 11 12 # 在数据库中查找是否有过收藏记录: 13 exist_record = UserFavorite.objects.filter(user=request.user, fav_id=int(id), fav_type=int(type)) 14 if exist_record: 15 # 记录存在，取消收藏 16 exist_record.delete() 17 18 # 收藏数减1 19 if int(type) == 1: 20 course = Course.objects.get(id=int(id)) 21 course.fav_nums -= 1 22 if course.fav_nums < 0: 23 course.fav_nums = 0 24 course.save() 25 elif int(type) == 2: 26 org = CourseOrg.objects.get(id=int(id)) 27 org.fav_nums -= 1 28 if org.fav_nums < 0: 29 org.fav_nums = 0 30 org.save() 31 elif int(type) == 3: 32 teacher = Teacher.objects.get(id=int(id)) 33 teacher.fav_nums -= 1 34 if teacher.fav_nums < 0: 35 teacher.fav_nums = 0 36 teacher.save() 37 return HttpResponse('{"status": "success", "msg": "收藏"}', content_type='application/json') 38 else: 39 # 记录不存在，收藏 40 user_fav = UserFavorite() 41 if int(id)>0 and int(type)>0: 42 user_fav.user = request.user 43 user_fav.fav_id = int(id) 44 user_fav.fav_type = int(type) 45 user_fav.save() 46 47 # 收藏数 48 if int(type) == 1: 49 course = Course.objects.get(id=int(id)) 50 course.fav_nums += 1 51 course.save() 52 elif int(type) == 2: 53 org = CourseOrg.objects.get(id=int(id)) 54 org.fav_nums += 1 55 org.save() 56 elif int(type) == 3: 57 teacher = Teacher.objects.get(id=int(id)) 58 teacher.fav_nums += 1 59 teacher.save() 60 return HttpResponse('{"status": "success", "msg": "已收藏"}', content_type='application/json') 61 else: 62 return HttpResponse('{"status": "fail", "msg": "收藏出错"}', content_type='application/json')
7、个人中心页面左侧选中状态
现在在usercenter-base.html页面中修改左侧导航栏选中状态的代码：
还有一个问题，就是我的收藏中删除机构收藏，需要修改usercenter-base.html页面中最下面的代码：
下面的教师和课程也是同样的改法。
