home模块

创建home模块

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

路由分发

主路由：luffyapi/urls.py

from django.urls import path, re_path, include
urlpatterns = [
	# ...
    path('home/', include('home.urls')),
    # ...
]

子路由：home/urls.py

from django.urls import path, re_path
urlpatterns = [

]

Banner数据表model设计

utils/model.py

from django.db import models

class BaseModel(models.Model):
    created_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')
    updated_time = models.DateTimeField(auto_now=True, verbose_name='最后更新时间')
    is_delete = models.BooleanField(default=False, verbose_name='是否删除')
    is_show = models.BooleanField(default=True, verbose_name='是否上架')
    orders = models.IntegerField(verbose_name='优先级')

    class Meta:
        abstract = True

home/models.py

from django.db import models
from utils.model import BaseModel

class Banner(BaseModel):
    title = models.CharField(max_length=16, unique=True, verbose_name='名称')
    image = models.ImageField(upload_to='banner', verbose_name='图片')
    link = models.CharField(max_length=64, verbose_name='跳转链接')
    info = models.TextField(verbose_name='详情')  # 也可以用详情表，宽高出处

    class Meta:
        db_table = 'luffy_banner'
        verbose_name_plural = '轮播图表'

    def __str__(self):
        return self.title

数据迁移：在大luffyapi路径下的终端

>: python manage.py makemigrations
>: python manage.py migrate

注册home模块：dev.py

INSTALLED_APPS = [
    # ...
    'rest_framework',
    'home',
]

设计Banner数据接口

home/serializers.py

from rest_framework import serializers
from . import models
class BannerSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Banner
        fields = ['title', 'image', 'link']

home/views.py

from rest_framework.viewsets import GenericViewSet
from rest_framework import mixins
from . import models, serializers

class BannerViewSet(GenericViewSet, mixins.ListModelMixin):
    queryset = models.Banner.objects.filter(is_delete=False, is_show=True).all()
    serializer_class = serializers.BannerSerializer

home/urls.py

from django.urls import path, include
from utils.router import router
from . import views
# 注册ViewSet的路由
router.register('banners', views.BannerViewSet, 'banner')

urlpatterns = [
    path('', include(router.urls)),
]

接口
