在django中创建标签并根据标签进行过滤

from django.db import models

class Tag(models.Model):
    name = models.CharField(max_length=50)

    def __str__(self):
        return self.name

from django.db import models
from .tag import Tag

class YourModel(models.Model):
    # 其他字段...
    tags = models.ManyToManyField(Tag)

from django.contrib import admin
from .models import Tag

admin.site.register(Tag)

from django.shortcuts import render
from .models import YourModel

def your_view(request):
    tag_name = request.GET.get('tag')  # 从请求参数中获取标签名
    if tag_name:
        queryset = YourModel.objects.filter(tags__name=tag_name)
    else:
        queryset = YourModel.objects.all()
    
    # 其他处理...
    
    return render(request, 'your_template.html', {'queryset': queryset})
