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 models


def music_upload(request):
    queryset = models.Music.objects.all()
    return render(request, 'music_upload.html', {'queryset': queryset})


from app01.utils.bootstrap import BootStrapModelForm


class UpModelForm(BootStrapModelForm):
    bootstrap_exclude_fields = ['music']

    class Meta:
        model = models.Music
        fields = "__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})
