export default {

Home模块创建:
"""
前提：在 luffy 虚拟环境下
1.终端从项目根目录进入apps目录
>: cd luffyapi & cd apps
2.创建app
>: python ../../manage.py startapp home
"""
注册home模块：dev.py
INSTALLED_APPS = [
# ...
'rest_framework',
'home',
]
路由分发
主路由:luffyapi/urls.py
from django.urls import path, re_path, include
urlpatterns = [
# ...
path('user/', include('home.urls')),
# ...
]
子路由:home/urls.py
from django.urls import path, re_path
from . import views
urlpatterns = [
path('banners/', views.BannerListAPIView.as_view())
]
Banner数据表model设计
基表:utils/model.py
from django.db import models
class BaseModel(models.Model):
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:
abstract = True
home/models.py
from django.db import models
from utils.model import BaseModel
class Banner(BaseModel):
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 = 'luffy_banner'
verbose_name = '轮播图'
verbose_name_plural = verbose_name
def __str__(self):
return self.name
数据迁移：在大luffyapi路径下的终端
# >: python manage.py makemigrations
# >: python manage.py migrate
设计Banner数据接口
序列化类:home/serializers.py
from rest_framework.serializers import ModelSerializer
from . import models
class BannerModelSerializer(ModelSerializer):
class Meta:
model = models.Banner
fields = ('name', 'note', 'image', 'link')
home/views.py
from rest_framework.generics import ListAPIView
from utils.response import APIResponse
from . import models, serializers
class BannerListAPIView(ListAPIView):
queryset = models.Banner.objects.filter(is_delete=False, is_show=True).order_by('-orders')
serializer_class = serializers.BannerModelSerializer
home/urls.py
from django.urls import path, re_path
from . import views
urlpatterns = [
path('banners/', views.BannerListAPIView.as_view())
]
接口:
http://api.luffy.cn:8000/home/banner/
前后台分离的前后台交互
后台处理跨域
安装插件:
>: pip install django-cors-headers
# 插件参考地址：https://github.com/ottoyiu/django-cors-headers/
项目配置：dev.py
# 注册app
INSTALLED_APPS = [
...
'corsheaders'
]
# 添加中间件
MIDDLEWARE = [
...
'corsheaders.middleware.CorsMiddleware'
]
# 允许跨域源
CORS_ORIGIN_ALLOW_ALL = True
前台请求Banner数据
修订Banner.vue
<template>
<el-carousel height="520px" :interval="3000" arrow="always">
<!-- 渲染后台数据 -->
<el-carousel-item v-for="banner in banner_list" :key="banner.name">
<a :href="banner.link">
<img :src="banner.image" alt="" :title="banner.note">
</a>
</el-carousel-item>
</el-carousel>
</template>
<script>
export default {
name: "Banner",
data() {
return {
banner_list: []
}
},
created() {
// 请求后台数据
this.$axios({
url: this.$settings.base_url + '/home/banners/',
method: 'get',
}).then(response => {
// window.console.log(response.data);
this.banner_list = response.data;
}).catch(errors => {
window.console.log(errors)
})
}
}
</script>
<style scoped>
.el-carousel__item h3 {
color: #475669;
font-size: 18px;
opacity: 0.75;
line-height: 300px;
margin: 0;
}
.el-carousel__item:nth-child(2n) {
background-color: #99a9bf;
}
.el-carousel__item:nth-child(2n+1) {
background-color: #d3dce6;
}
.el-carousel__item img {
text-align: center;
height: 520px;
margin: 0 auto;
display: block;
}
</style>
Xadmin后台管理：
安装：luffy虚拟环境下
# >: pip install https://codeload.github.com/sshwsfc/xadmin/zip/django2
注册app：dev.py
INSTALLED_APPS = [
# ...
# xamin主体模块
'xadmin',
# 渲染表格模块
'crispy_forms',
# 为模型通过版本控制，可以回滚数据
'reversion',
]
xadmin：需要自己的数据库模型类，完成数据库迁移
python manage.py makemigrations
python manage.py migrate
设置主路由替换掉admin：主urls.py
# xadmin的依赖
import xadmin
xadmin.autodiscover()
# xversion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),
]
创建超级用户：大luffyapi路径终端
# 在项目根目录下的终端
python manage.py createsuperuser
# 账号密码设置：admin | admin123
完成xadmin全局配置：新建home/adminx.py
# home/adminx.py
# xadmin全局配置
import xadmin
from xadmin import views
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)
在adminx.py中注册model：home/adminx.py
from . import models
# 注册
xadmin.site.register(models.Banner)
修改app:home的名字：xadmin页面上的显示效果
# home/__init__.py
default_app_config = "home.apps.HomeConfig"
# home/apps.py
from django.apps import AppConfig
class HomeConfig(AppConfig):
name = 'home'
verbose_name = '我的首页'
