注册首页路由

import Vue from "vue"
import Router from "vue-router"

// 导入需要注册路由的组件
import Home from "../components/Home"
Vue.use(Router);

// 配置路由列表
export default new Router({
  mode:"history",
  routes:[
    // 路由列表
    {
      name:"Home",
      path: "/home",
      component:Home,
    },
    {
      name:"Home",
      path: "/",
      component:Home,
    }
  ]
})

1.2轮播图功能实现

安装依赖模块和配置

图片处理模块

前面已经安装了，如果没有安装则需要安装

pip install pillow

上传文件相关配置

settings.py

# 访问静态文件的url地址前缀
STATIC_URL = '/static/'
# 设置django的静态文件目录
STATICFILES_DIRS = [
    os.path.join(BASE_DIR,"luffy/statics")
]

# 项目中存储上传文件的根目录[暂时配置]，注意，static目录需要手动创建否则上传文件时报错
MEDIA_ROOT=os.path.join(BASE_DIR,"luffy/statics")
# 访问上传文件的url地址前缀
MEDIA_URL ="/media/"

在xadmin中输出上传文件的Url地址

总路由urls.py新增代码：

from django.urls import re_path
from django.conf import settings
from django.views.static import serve

urlpatterns = [
  	...
    re_path(r'media/(?P<path>.*)', serve, {"document_root": settings.MEDIA_ROOT}),
]

创建轮播图的模型

因为当前功能是drf的第一个功能，所以我们先创建一个子应用home，创建在luffy/apps目录下

注册home子应用，因为子应用的位置发生了改变，所以为了原来子应用的注册写法，所以新增一个导包路径：

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# 新增一个系统导包路径
import sys
sys.path.insert(0,os.path.join(BASE_DIR,"apps"))



INSTALLED_APPS = [
	# 注意，加上drf框架的注册	
    'rest_framework',
    
    # 子应用
    'home',

]

注意，pycharm会路径错误的提示。

home/models.py

from django.db import models

# Create your models here.
class BannerInfo(models.Model):
    """
    轮播图
    """
    # upload_to 存储子目录，真实存放地址会使用配置中的MADIE_ROOT+upload_to
    image = models.ImageField(upload_to='banner', verbose_name='轮播图', null=True,blank=True)
    name = models.CharField(max_length=150, verbose_name='轮播图名称')
    note = models.CharField(max_length=150, verbose_name='备注信息')
    link = models.CharField(max_length=150, verbose_name='轮播图广告地址')
    orders = models.IntegerField(verbose_name='显示顺序')
    is_show=models.BooleanField(verbose_name="是否上架",default=False)
    is_delete=models.BooleanField(verbose_name="逻辑删除",default=False)

    class Meta:
        db_table = 'ly_banner'
        verbose_name = '轮播图'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name

数据迁移

python manage.py makemigrations
python manage.py migrate

效果：

序列化器

home/serializers.py

from rest_framework.serializers import ModelSerializer
from .models import BannerInfo
class BannerInfoSerializer(ModelSerializer):
    """轮播图序列化器"""
    class Meta:
        model=BannerInfo
        fields = ("image","link")

视图代码

views.py

from django.db.models import Q
from rest_framework.generics import ListAPIView
from .models import BannerInfo
from .serializers import BannerInfoSerializer
class BannerInfoListAPIView(ListAPIView):
    """
    轮播图列表
    """
    queryset = BannerInfo.objects.filter( Q(is_show=True) & Q(is_delete=False) ).order_by("-orders")
    serializer_class = BannerInfoSerializer

路由代码

urls.py

from django.urls import path,re_path
from . import views
urlpatterns = [
    path(r"banner/",views.BannerInfoListAPIView.as_view()),
]

把home的路由urls.py注册到总路由

from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("home.urls")),
]

访问http://api.luffycity.cn:8000/banner/，效果：

所以我们需要有一个后台提供数据.安装xadmin

pip install https://codeload.github.com/sshwsfc/xadmin/zip/django2

在配置文件中注册如下应用

INSTALLED_APPS = [
    ...
    'xadmin',
    'crispy_forms',
    'reversion',
    ...
]

# 修改使用中文界面
LANGUAGE_CODE = 'zh-Hans'

# 修改时区
TIME_ZONE = 'Asia/Shanghai'

xadmin有建立自己的数据库模型类，需要进行数据库迁移

python manage.py makemigrations
python manage.py migrate

在总路由中添加xadmin的路由信息

import xadmin
xadmin.autodiscover()

# version模块自动注册需要版本控制的 Model
from xadmin.plugins import xversion
xversion.register_models()

urlpatterns = [
    path(r'xadmin/', xadmin.site.urls),
]

如果之前没有创建超级用户，需要创建，如果有了，则可以直接使用之前的。

python manage.py createsuperuser

给xadmin设置基本站点配置信息

import xadmin
from xadmin import views

class BaseSetting(object):
    """xadmin的基本配置"""
    enable_themes = True  # 开启主题切换功能
    use_bootswatch = True

xadmin.site.register(views.BaseAdminView, BaseSetting)

class GlobalSettings(object):
    """xadmin的全局配置"""
    site_title = "路飞学城"  # 设置站点标题
    site_footer = "路飞学城有限公司"  # 设置站点的页脚
    menu_style = "accordion"  # 设置菜单折叠

xadmin.site.register(views.CommAdminView, GlobalSettings)

注册模型到xadmin中

在当前子应用中创建adminx.py，添加如下代码

# 轮播图
from .models import BannerInfo
class BannerInfoModelAdmin(object):
    list_display=["name","orders","is_show"]
xadmin.site.register(BannerInfo, BannerInfoModelAdmin)

修改后端xadmin中子应用名称

apps.py

class HomeConfig(AppConfig):
    name = 'home'
    verbose_name = '我的首页'

__init__.py

default_app_config = "home.apps.HomeConfig"

给轮播图添加测试数据

添加几条测试数据效果：

客户端代码获取数据

Banner.vue代码：

<template>
  <div class="banner">
      <el-carousel trigger="click" height="506px">
      <el-carousel-item v-for="item in banner_list">
        <a :href="item.link"><img :src="item.image"></a>
      </el-carousel-item>
    </el-carousel>
  </div>
</template>

<script>
  export default {
    name:"Banner",
    data(){
      return {
        banner_list:[],
      };
    },
    created: function(){
      // 获取轮播图
      this.$axios.get(this.$settings+"/banner/").then(response => {
        console.log(response.data)
        this.banner_list = response.data
      }).catch(error => {
        console.log(error.response);
      });
    }
  }
</script>

效果：

1.3导航功能实现

创建模型

引入一个公共模型【抽象模型，不会在数据迁移的时候为它创建表】

from django.db import models
from luffy.utils.models import BaseModel
# Create your models here.
class BannerInfo(BaseModel):
    """
    轮播图
    """
    # upload_to 存储子目录，真实存放地址会使用配置中的MADIE_ROOT+upload_to
    image = models.ImageField(upload_to='banner', verbose_name='轮播图', null=True,blank=True)
    name = models.CharField(max_length=150, verbose_name='轮播图名称')
    note = models.CharField(max_length=150, verbose_name='备注信息')
    link = models.CharField(max_length=150, verbose_name='轮播图广告地址')

    class Meta:
        db_table = 'ly_banner'
        verbose_name = '轮播图'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name


class NavInfo(BaseModel):
    """
    导航
    """
    NAV_POSITION = (
        (0, 'top'),
        (1, 'footer')
    )
    name = models.CharField(max_length=50, verbose_name='导航名称')
    link = models.CharField(max_length=250, verbose_name='导航地址')
    opt = models.SmallIntegerField(choices=NAV_POSITION, default=0, verbose_name='位置')

    class Meta:
        db_table = 'ly_nav'
        verbose_name = '导航'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name

公共模型，保存项目的公共代码库目录下luffy/utils.py文件中。

from django.db import models

class BaseModel(models.Model):
    """公共字段模型"""
    orders = models.IntegerField(verbose_name='显示顺序')
    is_show=models.BooleanField(verbose_name="是否上架",default=False)
    is_delete=models.BooleanField(verbose_name="逻辑删除",default=False)
    create_time = models.DateTimeField(auto_now_add=True,verbose_name="添加时间")
    update_time = models.DateTimeField(auto_now=True,verbose_name="更新时间")

    class Meta:
        # 设置当前模型在数据迁移的时候不要为它创建表
        abstract = True

数据迁移

python manage.py makemigrations
python manage.py migrate

序列化器代码

from rest_framework.serializers import ModelSerializer
from .models import NavInfo
class NavInfoSerializer(ModelSerializer):
    """导航序列化器"""
    class Meta:
        model=NavInfo
        fields = ("name","link")

视图代码

views.py

from .models import NavInfo
from .serializers import NavInfoSerializer
class NavInfoAPIView(ListAPIView):
    """
    导航列表
    """
    queryset = NavInfo.objects.filter( Q(is_show=True) & Q(is_delete=False) & Q(opt=0) ).order_by("-orders")
    serializer_class = NavInfoSerializer

路由代码

urls.py

from django.urls import path,re_path
from . import views
urlpatterns = [
    ...
	  path(r"nav/",views.NavInfoAPIView.as_view()),
]

注册模型到xadmin中

在当前子应用adminx.py，添加如下代码

# 导航
from home.models import NavInfo
class NavInfoInfoModelAdmin(object):
    list_display=["name","link","is_show"]
xadmin.site.register(NavInfo, NavInfoInfoModelAdmin)

添加测试数据

客户端代码获取数据

Header.vue代码：

<template>
  <div class="header">
    <el-container>
      <el-header>
        <el-row>
