全局导航&个人中心&全局搜索
配置全局导航
让index页面也继承base页面,注意首页有个单独的__index.js__
base页面的导航栏也进行配置
<nav>
<div class="nav">
<div class="wp">
<ul>
<li ><a href="{% url 'index' %}">首页</a></li>
<li >
<a href="{% url 'course:list' %}">
公开课<img class="hot" src="{% static "images/nav_hot.png" %}">
</a>
</li>
<li >
<a href="{% url 'org:teacher_list' %}">授课教师</a>
</li>
<li class="active" ><a href="{% url 'org:org_list' %}">授课机构</a></li>
</ul>
</div>
</div>
</nav>
但是现在我们不知道当前是哪一个页面，因为后端没有传值过来
这里可以使用request.path进行判断
比如http://127.0.0.1:8000/org/teacher_list/，则request.path 就是`/org/teacher_list/``
slice:12 是过滤器，取前12位数
利用这种方法可以达到全局的“active”效果，而不用每个子页面都要去设置“active”了
<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: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>
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_course = all_course.filter(
Q(name__icontains=search_keywords) | Q(desc__icontains=search_keywords) | Q(
detail__icontains=search_keywords))
搜索的代码放在deco-common.js中
如果自己写的url和js文件中的不同,可自行修改
//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))
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_teacher.filter(name__icontains=search_keywords)
个人中心信息展示
新建usercenter-bae.html当模板
进行配置
path("users/", include('users.urls', namespace="users")),

app_name = 'users'
urlpatterns = [

path("info/", UserinfoView.as_view(),name='user_info'),
]
class UserinfoView(LoginRequiredMixin,View):
'''用户个人信息'''
def get(self,request):
return render(request,'usercenter-info.html',{})
前端显示个人信息

修改密码和修改头像
#用户图像上传
path("image/upload/", UploadImageView.as_view(),name='image_upload'),
新建一个用于保存图片的form
这里继承的是ModelForm,该类具有save功能
# 用于文件上传，修改头像
class UploadImageForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ['image']
class UploadImageView(LoginRequiredMixin,View):

if image_form.is_valid():
image_form.save()
# 所有验证通过的字段放在cleaned data
# # 取出cleaned data中的值,一个dict
# image = image_form.cleaned_data['image']
# request.user.image = image
# request.user.save()
return HttpResponse('{"status":"success"}', content_type='application/json')
else:
return HttpResponse('{"status":"fail"}', content_type='application/json')
#用户个人中心修改密码
path("update/pwd/", UpdatePwdView.as_view(),name='update_pwd'),
# 在个人中心修改用户密码
class UpdatePwdView(View):

user =request.user
# 加密成密文

# 验证失败说明密码位数不够。
else:

Ajxa代码放在deco-user.js里面
如果url不正确可自行配置'
如果遇到403,检查base中的csrf_token是否填写
发送修改邮箱验证码
有两个接口需要完成。点击获取验证码时，后台需要向用户新邮箱发送验证码。
邮箱如果出错，会返回错误信息。
输入了邮箱和验证码，验证是否匹配。
给EmailVerifyRecord再添加一个选择类型
SEND_CHOICES = (
("register", "注册"),
("forget", "找回密码"),
("update_email", "修改邮箱")
)
#发送邮箱验证码
path("sendemail_code/", SendEmailCodeView.as_view(),name='sendemail_code'),
# 发送邮箱验证码view

email = request.GET.get("email", "")
# 不能是已注册的邮箱

return HttpResponse('{"email":"邮箱已经存在"}', content_type='application/json')
send_register_eamil(email, "update_email")
return HttpResponse('{"status":"success"}', content_type='application/json')
修改utils/email_send.py
if send_type == "update_email":
email_title = "慕课在线 修改邮箱"
email_body = "验证码:{0}".format(code)
# 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，从哪里发，接受者list
send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
# 如果发送成功
if send_status:
pass
修改邮箱
#修改邮箱
path("update_email/", UpdateEmailView.as_view(),name='update_email'),
# 修改邮箱的view:

code = request.POST.get("code", "")

个人信息修改
# 个人中心信息修改
class UserInfoForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ['nick_name','gender','birthday','address','mobile']
给UserinfoView添加post方法
class UserinfoView(LoginRequiredMixin,View):
'''用户个人信息'''
def get(self,request):
return render(request,'usercenter-info.html',{})
def post(self, request):
# 需要指明instance。不然无法修改，而是新增用户
user_info_form = UserInfoForm(request.POST, instance=request.user)
if user_info_form.is_valid():
