如何使用django信号刷新特定页面

# signals.py
from django.db.models.signals import post_save
from django.dispatch import receiver
from django.core.cache import cache
from .models import YourModel

@receiver(post_save, sender=YourModel)
def refresh_specific_page(sender, instance, **kwargs):
    # 假设我们使用缓存来标记页面是否需要刷新
    cache_key = 'refresh_page_flag'
    cache.set(cache_key, True, timeout=60)  # 设置缓存60秒

# apps.py
from django.apps import AppConfig

class YourAppConfig(AppConfig):
    name = 'your_app'

    def ready(self):
        import your_app.signals

# views.py
from django.shortcuts import render
from django.core.cache import cache

def your_view(request):
    cache_key = 'refresh_page_flag'
    if cache.get(cache_key):
        # 执行刷新页面的逻辑
        # 例如，重新获取数据并渲染模板
        data = YourModel.objects.all()
        cache.delete(cache_key)  # 清除缓存标志
    else:
        data = YourModel.objects.all()
    
    return render(request, 'your_template.html', {'data': data})
