使用Django框架实现音频上传功能

数据库设计（models.py）

class Music(models.Model):""" 音乐 """name = models.CharField(verbose_name="音乐名字", max_length=32)singer = models.CharField(verbose_name="歌手", max_length=32)# 本质上数据库也是CharField,自动保存数据。music = models.FileField(verbose_name="音频", max_length=128)

链接（urls.py）

# 音频上传path('music/upload/', music.music_upload),path('music/add/', music.music_add),

处理代码（music.py）

from django.shortcuts import render, redirect
from app01 import modelsdef music_upload(request):queryset = models.Music.objects.all()return render(request, 'music_upload.html', {'queryset': queryset})from app01.utils.bootstrap import BootStrapModelFormclass UpModelForm(BootStrapModelForm):bootstrap_exclude_fields = ['music']class Meta:model = models.Musicfields = "__all__"def music_add(request):""" 上传文件和数据 """title = "音频上传"if request.method == "GET":form = UpModelForm()return render(request, 'upload_form.html', {"form": form, "title": title})form = UpModelForm(data=request.POST, files=request.FILES)if form.is_valid():# 对于文件:自动保存;# 字段 + 上传路径写入到数据库form.save()return redirect("/music/upload/")return render(request, 'upload_form.html', {"form": form, "title": title})
