models
模型中有文章主表DetailInfo
、文章分类表Types
、文章资源表ResourcesLink
,有一对多和多对多的关系。
1、models.py
:
`# 文章分类
class Types(models.Model):
name = models.CharField(max_length=10,verbose_name="类型名称")
#文章信息表
class DetailInfo(models.Model):
title = models.CharField(max_length=200,blank=False,verbose_name="文章名称")
types = models.ManyToManyField(Types,verbose_name="文章类型")
context = models.TextField(max_length=1024,verbose_name="文章内容")
...
# 文章资源表
class ResourcesLink(models.Model):
detailinfo = models.ForeignKey(DetailInfo, on_delete=models.CASCADE,verbose_name="文章信息")
title = models.CharField(max_length=200,verbose_name="资源名称")
link = models.CharField(max_length=500,verbose_name="资源链接")
...`
2、json数据格式
[
{
"标题": "小武",
"内容": "测试",
"类型":["情感","文学","散文"]
"文章资源":[{
"title":"小武.1998.HD.1080p.x264.aac.Mandarine .CHS.mkv ",
"links":"https://www.xxx1.com"
},
{
"title":"小武.1998.HD.1080p.x264.aac.Mandarin.CHS.mp4",
"links":"https://www.xxx2.com"
}]
},
{
...
}
]
3.实现批量插入数据
from (自己项目名称).wsgi import *
from (app名称).models import Types,DetailInfo,MagnetLink
import json
def insertDB():
with open('E:workspacexxxxx.json', 'r', encoding='utf8') as f:
data = json.load(f)
for list in data:
#先写入分类(多对多关系)
for t in list['类型']:
c = Types.objects.get_or_create(name=t)[0]
# 然后插入文章
article = DetailInfo.objects.get_or_create(title=list['标题'],
context=list['内容'])[0]
# 获取文章id
article_id = article.id
for m in list['文章资源']:
print(m)
# 根据文章id将数据插入到文章资源表中(一对多)
ResourcesLink.objects.get_or_create(detailinfo_id=article_id,title=m['title'],link=m['links'])[0]
#最后将分类添加到文章中
article.types.add(c)
